title: [Drug treatment of hypertrophic cardiomyopathy].
abstract: Both, beta-receptor blocking agents and calcium-antagonists have been proven to be very effective in the treatment of idiopathic hypertrophic cardiomyopathy. In the vast majority of patients they lead to a significant reduction of the predominant clinical symptoms--angina and dyspnea--or even abolish them. Since beta-blockers primarily act on the contractile behaviour of the left ventricle they are especially suited in the obstructive form of the disease where they reduce outflow tract obstruction. In contrast, calcium-antagonists seem to mainly influence diastolic muscle mechanics by increasing diastolic distensibility, and thus may be indicated in the nonobstructive forms of hypertrophic cardiomyopathy. In cases with severe, life-threatening arrhythmias especially if associated with syncope, an antiarrhythmic therapy is mandatory.
