Unusual Features of Apical Hypertrophic CardiomyopathyAmerican Journal of CardiologyVol. 105Issue 6PreviewApical hypertrophic cardiomyopathy (HC) is commonly regarded as a relatively benign condition of young to middle-aged Japanese men. Apical HC in a predominantly Caucasian population is not well characterized. The cardiovascular characteristics, morbidity, and mortality of a series of elderly, predominantly Caucasian subjects with apical HC are described. Thirty-two consecutive patients with apical HC (mean age 71 years, 15 men) were identified from a teaching hospital without a specialized HC clinic. Full-Text PDF
