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 confirmed 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.
