All remained asymptomatic at long term follow-up. Although clinical COVID-19 cases with myocardial injury and normal coronary arteries have been reported and thought to be caused by myocarditis, here we show for the first time that ST-segment–elevation myocardial infarction may be caused by extensive microvascular thrombosis in the absence of epicardial coronary obstruction. Cardiac magnetic resonance imaging was later performed and showed epicardial delayed enhancement consistent with myocarditis. Ten patients had fever in the 3 days prior to admission. The ECG findings most commonly seen in myocarditis are diffuse T wave inversions; saddle-shaped ST-segment elevations may be present (these are also seen in pericarditis). Acute myocarditis may mimic an infarction. All remained asymptomatic at long term follow-up. Physicians should take into consideration several lines of evidence, such as clinical presentation, ECG alterations and cardiac enzyme changes, … He received fibrinolytic therapy for presumed STEMI. Related Topics. On admission, his electrocardiogram showed a sinus rhythm with a rate of 75 beats per minute and mild ST elevations in leads I, II, AVF, V4, V5, and V6(Figure 1). Echocardiography revealed preserved left ventricular ejection fraction in 32% of case reports and 51% of cases in the observational study; however, preserved systolic function did not predict greater survival. It has been found that group A streptococcus may be responsible for more cases of infection-induced acute myocarditis than previously thought, and often without the clinical features of rheumatic fever. Coronary angiogram revealed smooth arteries with no obstruction. A repeat troponin I level was markedly increased at 45.8 ng/mL. Myopericarditis: Widespread concave ST elevation (pericarditic changes) in a child with viral myocarditis. ST elevation myocardial infarction (STEMI) causes localized ST elevations, meaning that there are ST elevations in a few leads which are anatomically neighbouring (so called contiguous leads).
Troponin was significantly elevated and the echocardiogram exhibited mildly impaired LV function with hypokinetic … He presented with chest pain and the EKG changes were consistent with infero-laeral ST-segment elevation MI. In our experience in the last 6 years in a primary care coronary care unit of Southern Italy, we observed 11 patients with striking similarities in clinical presentation, laboratory findings, in-hospital outcome and long-term follow-up, … We report a case of focal myocarditis in a young boy mimicking acute ST-segment elevation MI.

Pericarditis; LITFL Further Reading . Die ST-Hebung kann auch als Normvariante in rechtspräkordialen Brustwandableitungen vorkommen. Acute myocarditis can mimic ST-elevation myocardial infarction (STEMI). The most common abnormality seen in myocarditis is sinus tachycardia with non-specific ST segment and T wave changes. Upon further questioning, he acknowledged 3 days of stuttering chest discomfort and a recent upper respiratory infection, as well as similar chest pain in his wife.A systematic evaluation is essential for acute chest pain, including a focused history, identification of cardiac risk factors, and ECG interpretation. His initial cardiac troponin T was 0.44 ng/mL. ECG Library … Acute myocarditis mimicking ST segment elevation myocardial infarction is a well-known phenomenon, but recurrence and progression are rare.
