RESUMO
Eleven patients of apical hypertrophic cardiomyopathy were studied by clinical, electrocardiography, systolic and diastolic time intervals, echocardiographic and pulsed Doppler methods. The patients were between 20-55 years of age. There were 10 males and 1 female. Chest discomfort was the predominant symptom. ECG revealed giant T wave inversion in precordial leads in six cases, LAHB and LBBB in 2 cases and abnormal Q waves in 2 cases. Systolic function was normal. However indices of diastolic function (IVRT, RF wave, a/H, LAEI) were abnormal. There was marked increase in the thickness of left ventricle towards the appex (septum 30.4 +/- 3 mm, LVPW 23.2 +/- 7 mm with cavity obliteration). SAM of AML was not observed. Doppler flow studies across aortic and mitral valves were normal.
