Abstract

We recently experienced 2 cases of a novel cardiomyopathy following various stressful conditions. Here, we report on this novel cardiomyopathy showing transient left ventricular apical wall motion abnormalities following stress. Our cases exhibited an acute onset, transient left ventricular apical wall motion abnormalities with chest symptoms, electrocardiographic changes and minimal enzyme release, which mimicked acute myocardial infarction without stenosis on the coronary angiograms. The novel cardiomyopathy developed in our patients following aggravation of a systemic disorder (acute pyelonephritis with septicemia) and noncardiac surgery (total hysterectomy). Both our cases exhibited the typical echocardiographic findings of asynergy of the apical region with hypercontraction of the basal segment of the left ventricle, and wall motion abnormalities, which improved rapidly within a few weeks.
