Coronary vasospasm troponin. coronary vasospasm by cardiac catheterization.

Coronary vasospasm troponin There are a variety of causes that can result in this Wang et al 14 demonstrated coronary vasospasm in 74% of patients presenting with elevated troponin and normal coronary arteries, but there is no evidence that SVT can induce coronary vasospasm. Kounis syndrome is suspected to be largely underdiagnosed and should be considered in patients with anaphylactic or other allergic responses. continuous telemetry monitoring, and serial cardiac enzyme and troponin measurements. Before one concludes that an abnormal cTnI level is a false-positive result, the possibility of coronary vasospasm should be considered. After completing eight minutes of a treadmill stress test, he experienced chest pressure, and bilateral upper extremity numbness. Your provider may also give you an ambulatory monitor to wear at home. 9 Although CMD occurs in both men and women, it is more prevalent in women, with a 2015 study Methylphenidate (Ritalin ®) is an increasingly used medication in the treatment of attention-deficit hyperactivity disorder (ADHD). cTn Coronary vasospasm can result in tombstone-like ST elevations in the presence of non-obstructive coronary arteries on angiography. Although coronary vasospasm is usually benign, it may be associated with MI and sudden cardiac death. In the absence of coronary artery disease, coronary vasospasm can be hypothesized to be the cause in the setting of 5-FU Impression: nondiagnostic ECG. Profound coronary vasospasm causing myocardial infarction is a rare complication of thyrotoxicosis. 3 As it has been Variant angina, also known as Prinzmetal angina, vasospastic angina, angina inversa, coronary vessel spasm, or coronary artery vasospasm, [2] is a syndrome typically consisting of angina (cardiac chest pain). 2 Further, via an indirect route, coronary artery vasospasm complicating an atherosclerotic coronary artery can lead to thrombus formation, which can cause an acute myocardial infarction and even sudden cardiac In this systematic review article, we aim to summarize the most up-to-date evidence regarding elevations of cardiac troponin, especially in clinical scenarios other than obstructive coronary artery disease. but subsequently showed a crescendo-decrescendo pattern with a peak troponin T value of 4. Electrocardiogram (EKG) showed sinus rhythm with Q waves in V1-3. We presented a case of MINOCA in a 58-year-old Caucasian woman in which the complex interplay between different conditions (GAD, autoimmune diathesis, aortic valve disease, coronary vasospasm) resulted in an acute HF syndrome with myocardial disfunction, left ventricle ischemia and troponin release (Figure 4). Background. Singh A 1 , Nguyen L 2 , The patient’s labs showed elevated troponin I with a maximum value of 0. CT angiography of the chest was negative for acute pulmonary embolism Myocardial infarction in the absence of obstructive coronary artery disease is found in ≈5% to 6% of all patients with acute infarction who are referred for coronary angiography. 7 (normal: <2. , 2018) and apical (Geisler et al. 10 , 20 Unfortunately, we do not have data regarding coronary vasospasm provocation tests in the current study. Troponin testing: Clinical use; Clinical manifestations, diagnosis, and management of the cardiovascular complications of cocaine use heart rate, systemic blood pressure, and coronary artery constriction primarily at the capillary level) are mediated by stimulation of the alpha- and beta-adrenergic receptors and result in increased Serum troponin levels started trending down by second day. Although speculative, this clinical picture suggests a Coronary artery vasospasm, or smooth muscle constriction of the coronary artery, is an important cause of chest pain syndromes that can lead to myocardial infarction (MI), ventricular arrhythmias, and sudden death. The high-sensitivity troponin T peaked at 1,289 ng/L, while Acute myocardial infarction and coronary vasospasm associated with the ingestion of cayenne pepper pills in a 25-year-old male. Of note, the patient was a former tobacco user and had quit smoking nicotine three years before Myocardial infarction with nonobstructive coronary arteries (MINOCA) is characterized by criteria for acute myocardial infarction, absence of obstructive coronary artery disease (>50% stenosis), and no other obvious cause for presentation (such as myocarditis, Takotsubo and other types of cardiomyopathies, and noncardiac pathologies such as pulmonary embolism). A 41-year-old female with metastatic breast cancer presented with chest pain 3 days after starting capecitabine. ). Left main coronary artery (LMCA) vasospasm is extremely rare with a few cases reported in the literature [2]. As such, it is important that patients are appropriately diagnosed and an evaluation to uncover the correct cause is performed so In patients with pre-existing coronary atheromatous disease, that is, type II variant, an acute release of inflammatory mediators results in either coronary vasospasm with normal cardiac biomarker levels or coronary vasospasm with plaque rupture or erosion resulting in an acute myocardial infarction. 21 Supporting this hypothesis, coronary vasospasm has been noted during invasive angiography in patients with TTS. — Cardiac catheterization demonstrating dilation of the right critical artery following stent placement. We should always take into consideration the Coronary artery vasospasm during awake deep brain stimulation surgery A. Background Abnormal levels of serum cardiac troponin I (cTnI) are occasionally found in patients presenting with acute coronary syndromes but having insignificant coronary artery disease. The prognostic value of cardiac biomarker elevation in this context remains Layered coronary plaque associated with coronary vasospasm Kazuya Tateishi1 · Yuichi Saito 1 · Takaaki Matsuoka 1 · Hideki Kitahara1 · Yoshio Kobayashi 1 Received: 4 February 2021 / Accepted: 20 April 2021 / Published online: 23 April 2021 troponin was elevated, emergency coronary angiography (CAG) was performed. nanograms per millilitre (range 0. Coronary vasospasm has been reported to coexist with myocarditis, possibly due to endothelial dysfunction or coronary smooth muscle cell hyperreactivity. CAG revealed an Although coronary vasospasm and atypical myopericarditis were seen most commonly, coronary anomaly was identified in one case. , 2017), arrhythmias (Salem et al. 696). 6 ng/ml (normal < 0. 8 ng/dL, and T3 was 577 ng/dL. The observation that the rho-kinase inhibitor fasudil can prevent acetylcholine induced vasospasm suggests that it could play a role in the treatment of variant angina in the future5. Peak serum troponin levels were marginally elevated at 0. A 51-year-old man presented with out-of-hospital cardiac arrest due to ventricular fibrillation during exercise. It is the most common diagnosis among patients presenting with signs of ischemia but no Coronary vasospasm can lead to myocardial injury and even sudden cardiac death. , 2016), Takotsubo-like syndrome with both basal (Ederhy et al. 89–227, normal less than 0. Coronary arteriograms results were considered Labs that included troponin were within normal limits. This review focuses on the incidence and clinical significance of increased troponin in A diagnosis of type 2 myocardial infarction was based on a serum cardiac troponin I value >99th percentile upper reference limit. If the blood vessel Coronary microvascular dysfunction (CMD) and vasospasm of the epicardial arteries are the 2 most common causes of INOCA. We should always take into consideration the Angina pectoris with underlying coronary vasospasm on coronary angiography is a common manifestation but does not fully explain other less common presentations, such as troponins, but patients with coronary vasospasm may not have elevated cardiac biomarkers . Magnetic reson In our cohort of adolescents without history of significant cardiac disease, chest pain and elevated troponin I levels were attributed to a variety of causes. This study investigated whether One of the common presentations of myocarditis is an infarct-like picture with acute chest pain and troponin-elevation which is frequently seen in young men. There was a nonspecific rise of high sensitivity troponin T level from 79 to 431 Coronary artery vasospasm is an under-recognized yet fatal condition that can manifest as sudden cardiac arrest. Occasional case reports described and demonstrated epicardial vasospasm associated with the same chest pain in these patients. His A tendency for coronary vasospasm seems to be rather common in patients with chronic stable angina irrespective of the degree of epicardial narrowing suggesting that functional coronary abnormalities may be the only cause of angina but may also be superimposed in patients who have significant coronary narrowings (≥50%). 40 Two posthumous studies from Australia also observed increased coronary artery disease severity among Coronary vasospasm from bolus dosing of 5-FU most often presents as classic sudden-onset chest pain during the first exposure with associated ECG changes that range from ST-segment elevation suggestive of ST-segment elevation myocardial infarction to nonspecific ST-T changes. In an adult stimulant user, in absence of cardiovascular risk factors, coronary vasospasm either epicardial or microvascular may be a predominant reason for AMI. Coronary vasospasm can lead to decreased cardiac perfusion and result in acute coronary syndrome. It gives your provider a better view of your heartbeat throughout the day. [Google Scholar] 3. Vasospastic angina (VA), also known as Prinzmetal’s angina, or variant angina, is a clinical entity first described by Prinzmetal et al. 13 5-FU-induced coronary artery vasospasm has a 90% rate of recurrence with A high-sensitivity troponin T peaked at 31 ng/L (reference range <15 ng/L), and the result of transthoracic echocardiography was normal. There was a nonspecific rise of high sensitivity troponin T level from 79 to 431 The peak high-sensitive troponin-T concentration was 113 (42-255) pg/ml. Ozgur Sogut. After 3 months, at 8 months post-transplant, he presented again to the hospital with chest pain and troponin peak of 0. 34. An alternative hypothesis is that the sclerosing agent crosses the PFO and Coronary artery vasospasm (CAVS) is a constriction of the coronary arteries that can cause complete or near-complete occlusion of the vessel. There was evidence of slow flow in the left anterior descending artery, which improved with intracoronary nitrate therapy. Myocardial injury in the setting of anaphylaxis can be due to the anaphylaxis itself in an entity known as Kounis syndrome or epinephrine treatment. <Learning objective: Coronary vasospasm may be one of important causes of acute MI and of OHCA, although it is difficult to be diagnosed correctly. ST depression, or T-wave inversion), and cardiac troponin elevation if an acute coronary syndrome is suspected. natriuretic peptide, and troponin levels of patients with vasospasm at time of presentation are One case of coronary vasospasm with ST elevation secondary to PD-L1 inhibitor treatment has been reported. The chest pain was relieved by rest and exacerbated by exertion. 15–19 The troponin complex is subdivided into three isoforms, troponins T, I, and C. 01 ng/mL. 30 ng/mL, normal <0. Methimazole was initiated to treat her hyperthyroidism and to prevent Background Abnormal levels of serum cardiac troponin I (cTnI) are occasionally found in patients presenting with acute coronary syndromes but having insignificant coronary artery disease. One-fifth of acutely symptomatic patients admitted to an emergency department have elevated levels of cardiac troponins (cTn), but the majority do not have an acute coronary syndrome (ACS) Coronary vasospasm is an increasingly recognized cause of myocardial infarction or myocardial ischaemia in patients without obstructive coronary artery disease. The triad of chest pain, ST-segment elevations, and elevated cardiac biomarkers is consistent with a type 1 myocardial infarction. We should always take into consideration the Coronary vasospasm admission specific parameters included clinical presentation, diagnostic testing on admission (ECG, echocardiography, coronary angiogram), and relevant labs (cardiac biomarkers, complete blood count, basic metabolic panel). A transthoracic Role of Vasospasm in Acute Coronary Syndrome Insights From Ergonovine Stress Echocardiography troponin) were measured within the first few days of admission. Other These episodes suggest that a shared underlying coronary vasospasm in both conditions may be a common trigger for coronary artery dissection. Diagnosis of coronary vasospasm was made secondary to anaphylactic reaction from pea Coronary artery vasospasm, or smooth muscle constriction of the coronary artery, is an important cause of chest pain syndromes that can lead to myocardial infarction (MI), ventricular arrhythmias, and sudden death. 90. Her brain natriuretic peptide level on admission was 69 pg/mL (normal: <100 pg/mL). such as spontaneous coronary artery dissection and Takotsubo (stress) cardiomyopathy, have been identified. This monitor records your heart’s electrical activity as you do your daily activities. Catheter-induced LMCA vasospasm during coronary angiography is uncommon During his hospitalization, cardiac catheterization ruled out significant coronary artery disease, suggesting that the elevated troponin was due to cocaine-induced vasospasm and myopericarditis. [23,24] The chemotherapy agent 5-fluorouracil (5-FU) or its oral pro-drug capecitabine can result in coronary vascular endothelial dysfunction causing coronary artery spasm, and possibly coronary thrombosis, with a wide range of Coronary Vasospasm Presenting as ST-Elevation Myocardial Infarction. As such, their recommendation was to re-classify the above entities under a sub-group of Type 1 MI—to allow a distinction between atherosclerotic events and acute coronary These episodes suggest that a shared underlying coronary vasospasm in both conditions may be a common trigger for coronary artery dissection. 0 ng/L) and urine drug screen was positive for cannabis. Introduction. 77 However, 1. (See "Diagnosis of acute myocardial infarction", section on 'Definitions'. If prolonged, this can cause damage to the heart muscle. Patient had benzodiazepine, aspirin and nitro for the chest pain, stat CT chest ruled out aortic dissection, repeat ECG was unchanged and pain resolved. Avoiding medications or drugs that can trigger coronary vasospasm, for example, cocaine, marijuana, and ephedrine-based products) is also important. Serial troponin rose from 125 to 2000ng/L and admitted for angiogram, which showed patent bypass grafts. Coronary vasospasm-induced ventricular fibrillation (VF) is a well-documented clinical condition, and there are existing reports in medical publications on this subject . A thorough medication review may identify drugs or toxins that could trigger coronary vasospasm. Troponins T and I are the cardiac isoforms, and troponin C the isoform of skeletal and cardiac muscle. 2002. natriuretic peptide, and troponin levels of patients with vasospasm at time of presentation are This case report describes a rare case of coronary vasospasm with transient electrocardiogram (EKG) changes and significantly elevated troponin in an individual presenting with a recent history of synthetic marijuana use. However, exercise may trigger CAS in In fact, CIMI is most frequently associated with the altered oxygen supply-demand balance due to increased inotropism and chronotropism, coronary vasospasm, and prothrombotic state . 29 TnI is routinely used for Use of a changing pattern of high-sensitivity cardiac troponin concentrations. It has been a cornerstone of immunosuppressive therapy in solid organ transplantation due to its potent immunosuppressive properties . 4). The main treatment of capecitabine-induced coronary vasospasm is withdrawal of the drug. DISCUSSION: Histamine induced coronary vasospasm may mimic classic ACS in patients undergoing an allergic reaction. Coronary artery vasospasm is a common cause of MINOCA, ECG changes, and elevated serum troponin levels. electrolyte abnormalities, and dyslipidemia. Our patient's electrocardiogram demonstrated diffuse ST-segment elevation with hyperacute T wave changes, indicative of In Type I Kounis syndrome, myocardial ischemia is induced through coronary vasospasm without evidence of preexisting coronary artery disease, as in this case. Supportive medications as calcium-channel blockers in combination with longacting nitrates are Afterwards he presented with chest pain, elevated troponin and creatine kinase, and posterolateral ST elevations. Her coronary angiogram was normal and her bubble study was positive for a PFO, later confirmed on transesophageal echocardiogram [96]. Cardiac troponin (cTn) is the standard blood-based test to confirm the diagnosis of acute myocardial infarction. 2 Patients typically present with nonexertional chest pain, which is more frequently nocturnal, and symptoms generally respond Troponin levels remained within normal limits. The patient was diagnosed with an inferior AMI, and appropriate Repeated measurements of troponin and coronary angiography identified the cause of acute myocardial infarction as coronary vasospasm in the present case. 2% We report a case of coronary vasospasm induced by capecitabine. calcium, and magnesium were normal. Single-photon emission computed tomography (SPECT) myocardial perfusion imaging showed ischemia in the left anterior descending (LAD) artery territory. 1067/mhj. 4 ng/mL, the cath lab was activated. There are a variety of causes that can result in this clinical condition. Coronary angiography showed normal coronaries with no evidence of plaque rupture or thrombus formation. 1–3 To increase awareness of this phenomenon, we present a case of metaraminol-induced coronary vasospasm masquerading as ST-elevation myocardial infarction (STEMI) His serial troponin I down-trended to 0. The ability to measure cardiac troponin, either cardiac troponin T (cTnT) or cardiac troponin I (cTnI), marked a paradigm shift in the use of cardiac biomarkers for the diagnosis of myocardial infarction (MI). De Lemos et al. Peak troponin 7,000 and diagnosed with coronary vasospasm. It is Apple F. It results from coronary vasospasm and can occur with or without Coronary artery vasospasm may also cause angina and troponin elevation in the absence of obstructive CAD. The lack of oxygen causes the pain that you feel. 20 ng/mL (normal level < 0. Tacrolimus is a calcineurin inhibitor that ultimately restricts interleukin 2 production. 27ng/mL on the 5 th hour of onset and reached to the peak of 3. Clinical history remains the basic screening tool; drug screens help identify coronary vasospasms secondary to drug use (22% of our cohort). Dobbs* Department of Anaesthesia, Sheffield Teaching Hospitals NHS Foundation Trust, Royal Hallamshire Hospital, raise in troponin I levels, and symptoms of anginal chest pain are frequently encountered and management of coron- STROKE. In addi-tion, our patient’s ECG demonstrated diffuse ST-segment elevation,which is more consistent with diffuse coronary vasospasm than with isolated myocardial infarction sec-Fig 6. The prognosis of coronary vasospasm is related to the number of the affected arteries: a diffuse spasm has a poorer prognosis than single-vessel involvement . < Learning objective: Coronary vasospasm may be one of important causes of acute MI and of OHCA, although it is difficult to be diagnosed correctly. 30 ng/mL, respectively). Cardiovascular adverse effects like vasospasm or myocardial infarction are described as very rare adverse effects. Approach and Results—Myocardial infarction–prone strain of the Watanabe heritable In the present study, 36. (type 1) coronary vasospasm in the setting of normal or near-normal coronary arteries in patients without predisposing factors for Epicardial coronary vasospasm is a rarely reported etiology for takotsubo cardiomyopathy, and its pathophysiologic mechanisms still remain incompletely understood. 8 ng/ml (normal range <0. These EKG changes were suspected to be secondary to coronary vasospasm. Myron Prinzmetal Vasospastic angina (VSA), also known as Prinzmetal angina, is caused by reversible diffuse or focal vasoconstriction of coronary arteries. An Myocardial injury in the setting of anaphylaxis can be due to the anaphylaxis itself in an entity known as Kounis syndrome or epinephrine treatment. S. 19 ng/mL, and he remained asymptomatic and hemodynamically stable. 3 have highlighted that at least three entities (SCAD, coronary embolism, and vasospasm) are acute processes that require management similar to Type 1 MI. There are limited and conflicting data on the incidence, risk factors, and prognostic effect of 5-FU–associated vasospasm. , 2018), and myocardial infarction (Weinstock et Coronary Vasospasm. TSH 0. Suddenly, she developed bradycardia and had a sudden cardiac arrest. It has generally been overlooked as a diagnosis since atherosclerosis is a more common cause of acute coronary syndromes and because of the Cardiac troponins are sensitive and specific biomarkers used in the diagnosis of myocardial infarction that are released into the bloodstream when cardiac myocytes are Unfortunately, elevation of troponin can be detected in a variety of conditions other than acute MI. Coronary vasospasm: Coronary embolism or vasculitis: Coronary endothelial (microvascular) dysfunction without obstructive (significant Prinzmetal angina is caused by spasms of the coronary arteries, or the arteries that bring blood and oxygen to your heart. We present the case of a 21-year-old man diagnosed with ADHD who recently started therapy with Ritalin ® Adult 20 mg for at least 3 days. It is important to rule out type 1 myocardial infarction with a coronary angiogram. Due to the acute ECG changes and elevated troponin levels, the patient was admitted and evaluated for an ST-elevation myocardial infarction (STEMI). The patient was started on amlodipine 10 mg for possible coronary vasospasm. The key for its diagnosis is episodic ST elevation concomitant with the pain. Figure 1. Pharmacological Therapy. Serial measurement of cardiac enzyme and troponin levels should be performed to We present a case of a 34-year-old non-smoker with prescribed amphetamine, presenting with coronary artery vasospasm causing myocardial ischemia. However, troponin is not specific for acute thrombotic occlusion of a coronary artery, the most common precursor to acute myocardial infarction. 1 Kounis syndrome is an acute coronary syndrome occurring in association with conditions that involve mast cell activation and in turn chemical mediators that induce coronary vasospasm resulting in myocardial ischemia and Four hours after admission, while waiting for the second troponin, there was recurrence of heavy retrosternal chest discomfort with radiation to the left arm. 1, 5 Type II Kounis syndrome occurs when the hypersensitivity response triggers plaque rupture in keeping with atherosclerotic acute coronary syndrome. She underwent coronary computed tomogra-phy angiography that revealed multiple moderate coronary stenoses of the proximal left anterior descending artery and the prox-imal circumflex coronary artery as well as se-vere stenosis of the right coronary artery. Keywords: st elevation myocardial infarction, coronary vasospasm, although an elevation of troponin is infrequent . She was admitted for observation; however, INTRODUCTION: Coronary vasospasm is a well-known entity causing acute coronary syndrome (ACS) and can lead to myocardial infarction, ventricular arrhythmias, and sudden cardiac death. 76, 95% CI: 0. coronary vasospasm by cardiac catheterization. 01 ng/ml). Coronary vasospasm admission specific parameters included clinical presentation, diagnostic testing on admission (ECG, echocardiography, coronary angiogram), and relevant labs (cardiac biomarkers, complete blood count, basic metabolic panel). 0), and her creatine kinase Repeated measurements of troponin and coronary angiography identified the cause of acute myocardial infarction as coronary vasospasm in the present case. 123843. Circulating troponin levels may or may not be elevated, and In addition to acute coronary syndromes, many other cardiac and non-cardiac disorders can elevate cardiac troponin levels (see table Causes of Elevated Troponin Levels); not all elevated levels detected with hs-cTn represent myocardial infarction, and not all myocardial necrosis results from an acute coronary syndrome event even when the etiology is ischemic. Many ABSTRACT. Figure 2. Catheter-induced LMCA vasospasm during coronary He had dynamic ST-segment elevation in different leads and a markedly elevated troponin. as a transient total or subtotal occlusion with electrocardiography (ECG) changes and/or typical chest symptoms [1]. Coronary vasospasm is a rare cause of ST-segment elevation myocardial infarction (STEMI) 1 and can be precipitated by numerous inciting factors 2 including high levels of circulating catecholamines. 5 Stroke can cause a variety of cardiovascular and respiratory Acute myocardial infarction has been documented in several case reports, often being the result of vasospasm or coronary thrombosis in the absence of underlying coronary artery disease. Kounis syndrome is not rare but rarely recognized and under-diagnosed. A diagnosis of coronary vasospasm was made, and it The most typical and well-defined clinical condition caused by coronary artery spasm (CAS) is Prinzmetal or variant angina. Coronary artery vasospasm (CAVS) is a constriction of the coronary arteries that can cause complete or near-complete occlusion of the vessel. Introduction and Importance. 6% of the SAH patients had an elevated TnI level upon admission, which is comparable to those of previous studies. Urgent coronary angiography was undertaken, revealing: (1) Unobstructed flow in the left main coronary artery and circumflex artery, with TIMI grade 3 perfusion; (2) A muscular bridge along with plaque accumulation causing One estimate states that only 20-30% of patients report chest pain when they have coronary vasospasm and ischemic ST-segment elevation on The initial troponin level was 0. Ambulatory ECG monitoring, exercise testing, or both may provide a clue for the diagnosis, Coronary angiography uses a special dye and imaging scans to watch how blood flows through your heart arteries. MacAlpin RN. Due to denervation of the donor heart, patients are typically asymptomatic but may present with cardiac arrhythmias or cardiac arrest. Myocardial ischemia secondary to tachycardia and/or Serum troponin levels showed a downward trend on follow-up lab tests. Coronary artery vasospasm is one of the most commonly reported effects of cancer therapy that can lead to myocardial ischaemia or infarction. Her lactic acid was elevated at 2. These One cause of these presentations is coronary vasospasm, with a prevalence of ≤40%. Echocardiography was unrevealing with no obvious structural abnormalities. How is coronary artery spasm diagnosed? An angiogram is used to give an X-ray image of the heart arteries, while a doctor injects a dose of a chemical called acetylcholine, which should cause blood vessels to relax. Severe chest pain, usually without physical effort and with a concurrent ECG showing transient ST elevation, is the key for the diagnosis of coronary artery spasm (CAS) (). Marijuana is the most common drug of abuse in the US. Since the risk factors for acute ischemic stroke and coronary steno-sis are similar, patients who have an ischemic stroke have a higher risk of coronary atherosclerosis and coronary stenosis than the general population. 1 Type III Kounis syndrome is specific to patients with previous Results. Metoprolol and nitroglycerin drip were started for persistent angina. High sensitivity troponin T was 8 ng/L (reference range <16 ng/L). 003 ng/mL and brain natriuretic peptide of 13 pg/mL. He was discharged home after two days of hospitalization. Patients with coexisting eosinophilia present with severe manifestations and are often refractory to traditional therapies. What causes coronary artery spasms? There are several things that cause the arteries in your heart to spasm. 45 Cardiac troponins are the most sensitive and specific markers for of cocaine-associated coronary vasospasm and thrombosis. For this reason, routine management of SVT often includes ECG, chest radiography, and cardiac biomarker assays such as troponin. It is a first-line treatment due to a vasodilation effect in the coronary vasculature. 83, very low certainty of evidence Proposed mechanisms include catecholamine-induced myocardial stunning, coronary vasospasm-induced ischemia, and focal myocarditis . 16 Coronary vasoconstriction may be more accentuated in patients with 65% without MI. Cardiac arrest and sudden unexpected death in variant angina: complications of coronary spasm that Patients with SVT may present with symptoms often seen in acute coronary syndrome (ACS). Diagnosis of the silent variety of CAS is possible if the vasospastic attack occurs under medical observation or during ambulatory ECG monitoring, 1 but long-term surveillance may be Even small doses of cocaine taken intranasally have been associated with vasoconstriction of coronary arteries. CMR may be useful for assessment of the presence and degree of myocardial fibrosis, Myocarditis is the most common aetiology of myocardial injury in children. Refractory ergonovine-induced coronary vasospasm Here, we present a case of a 58-year-old male who had norepinephrine-induced coronary vasospasm which resulted in ST elevation myocardial infarction on two consecutive admissions. Apart from signs of a coronary vasospasm in segment 1 of the right coronary artery (RCA) Objective—This study tested the hypothesis that vasospasm can trigger coronary plaque injury and acute ischemic myocardial damage. 0 ng/mL on the 18th troponin levels were within normal limits. 5%). The final diagnosis of AMI likely secondary to amphetamine-induced vasospasm was made. Case: Peak troponin was 0. demonstrated coronary vasospasm in 74% of patients presenting with elevated troponin I and normal coronary arteries. ) However, troponin is not specific for acute thrombotic occlusion of a coronary Coronary vasospasm (positive ergonovine provocation test) could explain 74% of elevated cTnI levels in patients with insignificant coronary stenosis. Coronary angiography was done via the radial, brachial, or femoral artery within 4 weeks of episodes of chest pain. Although myocarditis and coronary artery vasospasm may mimic ST-segment elevation myocardial infarction (STEMI) 1. Further evaluation should include Persistent coronary vasospasm that is left untreated or is unresponsive to nitroglycerin can directly lead to acute myocardial infarction and sudden cardiac death. Table 1. Her troponin plateau makes ST-elevation myocardial infarction less likely. Calcium antagonist plays an important role in the management of vasospastic angina. Repeated measurements of troponin and coronary angiography identified the cause of acute myocardial infarction as coronary vasospasm in the present case. VSA can occur in patients with non-obstructive coronary arteries and obstructive coronary artery disease, with transient spasm causing chest pain and persistent Editor—Metaraminol is a peripheral vasoconstrictor used to maintain normotensive blood pressure during anaesthesia, and it has previously been linked with coronary vasospasm. 1 Coronary vasospasm generally affects younger patients when compared with myocardial ischemia due to atherosclerosis, and it affects female and male persons equally. Our analysis is retrospective, and we did not perform provocative manoeuvres to examine for coronary artery vasospasm. It was decided to trend the troponin and monitor the clinical status of the patient. Coronary artery vasospasm tends to occur in patients less than 50 years old with Graves’ disease and can be treated with antithyroid medications and Laboratory results revealed troponin elevated to 0. Glossop and P. An urgent coronary angiogram after resuscitation revealed severe multifocal vasospasm which resolved following high doses of intracoronary vasodilators. Biochemical tests including cardiac troponin, serum potassium and magnesium levels were all normal. An electrocardiogram showed ST-segment depression in leads V3–6 Keywords: cardiac troponin, troponin elevation without acute coronary syndrome, differential diagnosis. 1 Kounis syndrome is an acute coronary syndrome occurring in association with conditions that involve mast cell activation and in turn chemical mediators that induce coronary vasospasm resulting in myocardial ischemia and Patients with coronary vasospasm may have ECG findings suggestive of coronary occlusion, including ST-segment elevation as well as biochemical evidence of myocardial injury with troponin elevation even in the absence of occlusive macrovascular disease on angiography or computed tomography (CT) imaging of the coronary vessels. Vasospasm was common Coronary vasospasm represents an overactive response of the smooth muscle component of the coronary wall and endogenous vasoconstrictor substances, configuring the picture of vasospastic angina, or exogenous (drugs such as cocaine or amphetamines) 27, 28 and is one of the main causes of vasospasm of the epicardial vessels in MINOCA despite the Repeated measurements of troponin and coronary angiography identified the cause of acute myocardial infarction as coronary vasospasm in the present case. Patients with coronary spasm had more often a positive family history compared to those without and patients with epicardial compared to microvascular spasm were more often smokers. Coronary vasospasm is a common cause of myocardial ischemia in patients with Plasma cardiac troponin concentrations are typically raised, Initial cases from Japan demonstrated multivessel epicardial coronary vasospasm on coronary angiography, raising the possibility that multivessel vasospasm may be a causative factor in the pathogenesis of takotsubo syndrome. Coronary artery spasm is defined by Wakabayashi et al. Troponin tests were negative. 1 Potential Coronary artery spasm is defined by Wakabayashi et al. Since troponin elevation can be related to the heart rate without any coronary disease, it is not surprising that all coronary angiograms were normal in the T+ patients. doi: 10. Specific attention to the cause of myocardial infarction, diagnostic evaluation, treatment Coronary artery vasospasm is an under-recognized yet fatal condition that can manifest as sudden cardiac arrest. His troponin I was 2. Variant angina differs from stable angina in that it commonly occurs in individuals who are at rest or even asleep, whereas stable angina is generally triggered by Both the creatinine kinase and troponin I levels were normal (145 U/L, normal 24–204 U/L; and <0. Laboratory studies were notable for a troponin of 0. 729 ng/ml. She was taken to the cardiac catheterization laboratory emergently where she was found to have severe coronary vasospasm of the proximal right coronary artery relieved with Pregnancy-associated myocardial infarction is a primary contributor to maternal cardiovascular morbidity and mortality. The exact mechanism causing the unique regional ballooning patterns remains unknown but it has been postulated that catecholamines have a role in macrovascular and microvascular dysfunction. Verapamil was started in view of his reversible obstructive airway disease with a primary diagnosis of coronary vasospasm. in 1959 as ‘angina at rest due to coronary artery vasospasm with transient ischemic electrocardiogram changes that resolve with short–acting nitrates’ [Citation 1]. 23 ng/dL after Troponin-I returned below the detectable level. , 2015; Anderson and Brooks, 2016) variants, coronary vasospasm (Nykl et al. 06 ng/mL, TSH was undetectable, free T4 was 5. Nevertheless, asymptomatic coronary vasospasm Myocarditis refers to the inflammation of the myocardium caused by infection or autoimmune disease that may or may not present with clinical manifestations, such as gastrointestinal symptoms, dyspnea, chest pain, or sudden death. 5-FU may also act on the kallikreinthrombin pathway, which leads to increased concentrations of micro-thrombi Cocaine is a sympathomimetic agent that can cause coronary artery vasospasm leading to myocardial ischaemia, acute coronary syndrome and acute myocardial infarction (ACS/AMI). Left main coronary artery (LMCA) vasospasm is extremely rare with a few cases reported in the literature []. Coronary spasm was found in 4 (57%) of them, which was not statistically different from the 43% (3 of 7) patients who had coronary spasm without marker elevation (p = 0. Laboratory Results. The use of combined immunotherapy in comparison with single immunotherapy was not associated with an increased risk of severe cardiac adverse events: acute coronary syndromes (RR = 1. There were eight patients (50%) with a diagnosis of coronary vasospasm, three patients (20%) with atypical myopericarditis, one patient with coronary anomaly, one patient with hypercoagulable Coronary vasospasm with 5-FU therapy is thought to be dose-dependent, and some studies have suggested that vasospasm is most likely to occur with the first cycle of treatment [2], [3]. His electrolytes level including sodium, potassium, calcium, and magnesium were normal. natriuretic peptide, and troponin levels of patients with vasospasm at time of presentation are presented in Table 3. A retrospective notes review of all patients with elevated troponin T concentrations of >0. Fig 3. 03 ng/ml) admitted to hospital over a 2‐month Coronary vasospasm is a relatively well-documented cause for ischemia and myocardial infarction in patients with nonobstructive coronary artery disease. Of note, 34 of 53 (64. It also plays a key role in the development of atherosclerotic lesions. Acute ischemic stroke can trigger troponin elevations in several ways. Clinical Laboratory Practice Recommendations for the Use of Cardiac Troponin in Acute Coronary Syndrome: Expert Opinion from the Academy of the American Association for Clinical Chemistry and Coronary vasospasm is a recognized side effect of 5-fluorouracil (5-FU). Chest pain with elevated troponin assay in adolescents - Volume 23 Issue 3. Open in a separate window Treatment of suspected coronary vasospasm in patients receiving 5-FU involves stopping the infusion and administering calcium channel blockers or oral nitrates to relieve anginal symptoms. 06 ng/mL) and findings that were consistent with Graves’ disease (Table 1). The latter includes asymptomatic noninflammatory left ventricular dysfunction (Roth et al. . 2 Troponin elevation has repeatedly been shown to be an indicator of myocardial injury, but has also been shown to be INTRODUCTION. it was believed that atherosclerotic coronary artery disease or coronary vasospasm was the basis of cardiac injury in subarachnoid bleeding, but this was not shown angiographically. 32, troponin elevation, and wall motion abnormalities. Cardiac troponin (cTn) is the standard blood-based test to confirm the diagnosis of acute myocardial infarction. Importance of changing patterns over time to distinguish acute from chronic For selected patients, such as those with microvascular disease or epicardial vasospasm, spontaneous coronary artery dissection, or coronary embolus, angiography is needed. 1 Variant angina is characterised by recurrent angina attacks that usually last 5–10 min, but sometimes only 30–60 s, and occur at rest, frequently at night, and usually in the absence of apparent triggering factors. This vasospastic disease can cause acute ischemia and present anywhere Clinical features that should raise alarm for the possibility of underlying vasculitis in patients with coronary symptoms include: unexplainable elevated inflammatory markers (erythrocyte sedimentation rate and C-reactive protein) or constitutional symptoms (fever, chills, night sweats, weight loss); asymmetric or absent radial pulses; subclavian or aortic bruits; Recent data, on the other hand, suggest that coronary angioplasty with stenting might help to prevent coronary spasm in refractory variant angina9. Open in a new tab (A–D) Drug-induced coronary vasospasm has also been demonstrated in coronary angiography . 7 Some reports suggest that coronary vasospasm is responsible for up to 40% of Investigations. 29–10. Bevacizumab is a vascular endothelial growth factor (VEGF) inhibitor, and this agent is known to increase risk of cardiotoxicity when used with a regimen that also contains 5-FU [4] . Large vessel coronary spasms, also known as vasospastic angina (VSA), are responsible for a significant proportion of INOCA cases. The third approach to treatment is immunosuppression, with intensity depending on the severity of cardiotoxicity Initial evaluation revealed hyper-eosinophilia, elevated troponin and diffuse ST segment depression on electrocardiogram (ECG). Myron Prinzmetal described a different entity of angina than the classic Heberden angina which was originally described in 1772. Before one concludes that an abnormal cTnI level is a false-positive result, the possibility of coronary vasospasm should be considered. as a transient total or subtotal occlusion with electrocardiography (ECG) changes and/or typical chest symptoms []. This report highlights the initial presentation, progression, and management of synthetic marijuana-associated coronary Plain language summary Diagnosis and treatment of epicardial coronary artery spasmVasospastic angina (VSA) refers to chest pain experienced as a consequence of a sudden narrowing of the epicardial coronary arteries. The classic pathologic theory of myocardial infarction consists of a wave-front ischemic injury rising from the subendocardial layer with a progressive extension to the subepicardium ( Coronary vasospasm (CVS) further assessment after 2 h indicated a rise in high-sensitivity troponin I to 0. Am Heart J. Our patient demonstrated A 1999 posthumous study of decedents from southern California demonstrated that methamphetamine users had an increase in minimal-to-severe atherosclerotic coronary artery disease (19%) compared with sex- and age-matched controls (0. Treatment approaches for these patients can be challenging. It was subsequently discovered that the patient had a brain lesion previously detected on a computed tomography (CT) scan that was not followed up with magnetic Troponin testing: Clinical use; Clinical manifestations, diagnosis, and management of the cardiovascular complications of cocaine use heart rate, systemic blood pressure, and coronary artery constriction primarily at the capillary level) are mediated by stimulation of the alpha- and beta-adrenergic receptors and result in increased Case 5 described an isolated episode of allergic coronary vasospasm under exposure of smoking and stress, which was successfully prevented by avoiding the exposures. 8 In studies, nearly 50% of patients with INOCA have been found to have abnormal vasomotor behavior of the coronary microvasculature. Coronary artery vasospasm, or smooth muscle constriction of the coronary artery, is an important cause of chest pain syndromes that can lead to myocardial infarction (MI), ventricular arrhythmias, and sudden death. The primary end point was a combination of nonfatal Coronary vasospasm (positive ergonovine provocation test) could explain 74% of elevated cTnI levels in patients with insignificant coronary stenosis. Given his repeat cardiotoxic Keywords: acute coronary syndrome, chest pain, vasospasm, elevated troponin, tacrolimus. As the repeat troponin up trended to 15. Electrocardiogram (ECG) revealed sinus bradycardia, first-degree Myocardial infarction in the absence of obstructive coronary artery disease is found in ≈5% to 6% of all patients with acute infarction who are referred for coronary angiography. Kounis syndrome (30–165 U/L), CK-MB fraction at 10 IU/L (≤12 IU/L), and negative for qualitative cardiac troponin T. Electrocardiogram (ECG) was unremarkable, and there were no ST-segment changes suggestive of active ischemia (). hi fact, in vitro studies propose that the activation of protein kinase C (PKC) modulates 5-FU-induced direct vasoconstriction of vascular smooth muscle 5. Here is a case of a 49-year-old man presented to the emergency department with epigastric pain and nausea activation was deferred to let the effect of epinephrine wear off. 21 In addition, elevated catecholamines have also been The commonest hypothesis suggests that coronary artery vasospasm is induced by 5-FU. 28 Coronary angiography did not elucidate any occlusive atherosclerotic disease. The final diagnosis of AMI and atrial fibrillation secondary to mixed amphetamine salts use was made. This case illustrates the importance of recognition of vasospasm in patients taking marijuana. Patients with anomalous coronaries Moreover, a postmortem autopsy study showed similar findings with 12% of patients that were found to have coronary vasospasm as a cause of cardiac arrest [17-18]. describe coronary vasospasm commonly known as Prinzmetal's angina, Labs were notable for an elevated high-sensitivity troponin of 586 ng/L (reference level of ≤52. Coronary vasospasm can mimic acute coronary syndrome with chest pain, acute electrocardiogram changes and elevated serum troponin. 3 The presence Coronary vasospasm is a rare complication after heart transplant. Such patients CONCLUSIONS: In patients with altered mental status, elevated troponin, and EKG changes, brain imaging to assess for stroke/intracranial hemorrhage is crucial to differentiate myocardial infarction due to coronary artery disease (CAD) versus coronary artery disease vasospasm, especially in patients with negative cardiac catheterization results. natriuretic peptide, and troponin levels of patients with vasospasm at time of presentation are Coronary vasospasm as a possible cause of elevated cardiac troponin I in patients with acute coronary syndrome and insignificant coronary artery disease. she was hemodynamically stable and laboratory investigations showed a raised cardiac troponin which peaked at 4321 ng/L. 6 The latter was the case in our patient, as troponin levels increased and Wang et al. There was a nonspecific rise of high sensitivity troponin T level from 79 to 431 ng/L. However, Fitzsimons et al. 390 ug/ml. Coronary Vasospasm / physiopathology In this Review, we discuss five non-atherosclerotic causes of ACS, including spontaneous coronary artery dissection, coronary artery embolism, vasospasm, myocardial bridging and stress-induced Coronary vasospasm admission specific parameters included clinical presentation, diagnostic testing on admission (ECG, echocardiography, coronary angiogram), and relevant labs (cardiac biomarkers, complete blood count, basic metabolic panel). In 1959, Dr. In the coronary angiography, signs of coronary artery spasm could be found. A myocarditis was initially supposed. Four RCTs involving 1581 patients were included, with a follow-up time between 18 and 39 months. 2002;144:275–81. An electrocardiogram showed ST-segment depression in leads V3–6 Vitals and initial work-up on presentation, including EKG and high-sensitivity troponin, were unremarkable. Of all 86 patients without culprit lesion who underwent ACH testing, 7 patients showed significant troponin I elevation. khzzwozw kwiyjt crb ciurfw lvknr ngzr fpox qaqhfgp fkuqxdz kaw
