[Long-term prospective observation of patients with hypertrophic cardiomyopathy].

This paper summarizes results of a long-term prospective study of the patients with hypertrophic cardiomyopathy (GCMP) divided into two groups, one with progressive disease (42%) the other with its stable course (58%). The progress of GCMP was not associated with thickening of the left ventricle. Predictors of the progress included manifest and extensive asymmetry of myocardial hypertrophy. Dilatation cardiomyopathy developed in 5.5% of the cases of nonobstructive GCMP. Therapy had no significant effect on clinical manifestations of GCMP.
