In a 21-year-old male with apical hypertrophic cardiomyopathy and a coronary muscle bridge, extensive stress testing revealed no objective evidence of myocardial ischemia, emphasizing its benign nature.

We describe the case of a 21-year-old Italian male who presented with giant negative T-waves and left ventricular hypertrophy on the electrocardiogram suggestive of apical hypertrophic cardiomyopathy. Clinically, he suffered from new onset of exertional angina, dyspnea and palpitations during soccer playing or heavy exercise beginning one week before admission. Echocardiography and cardiac catheterization conformed the rare combination of a nonobstructive apical hypertrophic cardiomyopathy of the "Japanese" type coexistent with an extensive muscular bridge involving almost the entire anterior interventricular branch of the left coronary artery. Although the patient complained of exertional angina pectoris, absence of objective evidence of myocardial ischemia by means of treadmill stress test, exercise thallium scan, dobutamine stress echocardiography as well as atrial pacing stress emphasized the benign nature of this complex anomaly.
Giannitsis et al. (Wed,) conducted a case report in Apical hypertrophic cardiomyopathy with coronary muscle bridge (n=1). Diltiazem was evaluated on Objective evidence of myocardial ischemia. In a 21-year-old male with apical hypertrophic cardiomyopathy and a coronary muscle bridge, extensive stress testing revealed no objective evidence of myocardial ischemia, emphasizing its benign nature.
