title: [Myocarditis in the differential diagnosis of acute coronary syndrome].
abstract: A 69-year-old man with no remarkable medical history was admitted to the intensive care unit in septic shock due to severe community-acquired pneumonia. Twelve hours later he developed electrocardiographic abnormalities with ST elevation in leads II, III, aVF, V5, and V6 in the absence of chest pain and the presence of dyspnea, agitation, and hypertension. Serial measurements of cardiac enzymes were also elevated. Acute coronary syndrome was suspected. A cardiac ultrasound revealed left ventricular dilation with akinesia and systolic dysfunction (ejection fraction, 40%). Emergency catheterization revealed normal coronary arteries, suggesting a probable diagnosis of acute myocarditis. From the fourth day, the patient was progressing favorably. Findings in a follow-up ultrasound were consistent with the onset of dilated myocardiopathy, and angiotensin converting enzyme inhibitors were prescribed. All serology and microbiological studies were negative. Fifteen days after admission the patient was discharged to home after clinical, radiologic and analytic recovery.
