He had a medical history of diabetes mellitus and hyperlipemia without hypertension or myocarditis. However, he mentioned that his son had dilated cardiomyopathy (DCM) and ankylosing spondylitis (AS). Examination at admission revealed a blood pressure of 115/69 mmHg and pulse of 82 beats/min. The results of routine blood tests for creatine kinase (CK), CK muscle and brain (CK-MB), troponin T, and thyroid function were all within normal limits. ECG revealed I, aVL, and V4--6 T wave inversion (Figure 1). Ultrasonic cardiography showed that the left ventricular ejection fraction (EF) was 32%, in- dicating ventricular wall dysfunction. Angiography showed no coronary stenosis. Radionuclide imaging demonstrated myopathy of the anterior, part of the inferior, the posterior,and the lateral apical segments based on reduced radioactivity with a patchy pattern, consistent with DCM (Figure 2A).展开更多
