Abstract

A forty-one-year-old male, with no risk factors for coronary artery disease (CAD) and with moderate alcohol intake, was admitted in 1992 to Portalegre Hospital with heart failure due to viral cardiomyopathy. He was re-admitted in 1998 with acute pulmonary edema and was put on mechanical ventilation for 48 hours, and transferred to Pulido Valente Hospital when stable. The physical exam was without abnormalities. ECG showed first degree AV block, left ventricular hypertrophy and 2 mm ST depression in the precordial leads. The echocardiogram revealed left ventricular dilatation and depressed systolic function. Coronary angiography showed single-vessel CAD and coronary artery anomaly. Dobutamine stress echocardiography was halted due to hypertension, making it impossible to evaluate ischemic response. Holter monitoring showed five-complex ventricular tachycardia. The patient was discharged medicated with amiodarone, with indication for cardiac scintigraphy and electrophysiological study.
