Phantom Ischemia Mimicking ST Segment Elevation Myocardial Infarction in Fulminant Myocarditis
نویسندگان
چکیده
A 30-year-old man visited the emergency room for chest pain, dyspnea and fever. Despite increased serum cardiac enzymes, ST segment elevation and inferior wall akinesis in electrocardiography and echocardiography, no atherosclerosis was evident in the coronary angiography. However, radionuclide myocardial perfusion image at day 2 showed a persistent perfusion defect in the left ventricular (LV) inferior wall. At day 3, prominent myocardial edema and severe LV systolic dysfunction developed with signs of heart failure. In this case, fulminant myocarditis seemed to originate from the right coronary artery territory and simulated a ST segment elevation myocardial infarction without coronary artery obstruction. The pathogenesis of the localized perfusion defect was unlcear. (Ewha Med J 2012;35(2):129-134)

Atrial Repolarization Waves (Ta) Mimicking Inferior Wall ST Segment Elevation Myocardial Infarction in a Patient with Ectopic Atrial Rhythm
We present a case of atrial repolarization waves from an ectopic atrial rhythm mimicking inferior ST segment elevation myocardial infarction in a 78-year-old male patient who presented with left sided chest wall and shoulder pain. His ischemic workup was negative, and the ST elevations completely resolved upon the resumption of sinus rhythm before discharge.

A 58-year-old man presented himself to the emergency room with chief complaints of chest pain and progressively exacerbated dyspnea for 4 days. Electrocardiography showed Q wave and ST-segment elevation in inferior leads. A thallium scan showed mixed ischemia and infarction in the inferior wall of the left ventricle. However, coronary artery angiography showed normal coronary arteries. Cardiac ...

Acute myocarditis mimicking ST-segment elevation myocardial infarction (STEMI) is highly deceptive for an accurate diagnosis, and a systematic study is lacking with regard to the clinical features and prognosis of this distinct clinical entity.Patients with suspected STEMI and eventually diagnosed with myocarditis by cardiac magnetic resonance (CMR) from January 2012 to April 2016 at Fuwai Hosp...
متن کاملAcute perimyocarditis mimicking transmural myocardial infarction
Although acute pericarditis has charachteristic electrocardiographic (ECG) findings that differentiate it from acute ST segment elevation myocardial infarction (MI); in certain cases diagnosis is somewhat difficult especially when the ECG reveals focal instead of diffuse changes and moreover when pericarditis is associated with an underlying myocarditis causing elevation of the cardiac biomarke...
متن کاملPresumptive myocarditis with ST-Elevation myocardial infarction presentation in young males as a new syndrome. Clinical significance and long term follow up
BACKGROUND Acute myocarditis may mimic myocardial infarction, since affected patients complain of "typical" chest pain, the ECG changes are identical to those observed in acute coronary syndromes, and serum markers are increased. We describe a case series of presumptive myocarditis with ST segment elevation on admission ECG. METHODS AND RESULTS From 1998 to 2009, 21 patients (20 males; age 17...
