Calcium-channel blockers are useful for the treatment of hypertrophic cardiomyopathy (HCM), but, their adverse effects, especially, those of diltiazem, have not been of much concern. Effects of beta-blockers (propranolol, penbutolol) and calcium antagonists (nifedipine, verapamil, diltiazem) were studied in 73 patients with hypertrophic cardiomyopathy (HC). Clinical trials have suggested that long-term administration of verapamil in patients with hypertrophic cardiomyopathy promotes improvement in symptomatic status and exercise tolerance in many but not all patients; similar results have been reported in preliminary studies using nifedipine. Calcium channel blockers prevent calcium from entering into the heart muscle cells, and into the smooth muscle cells that cause blood vessels to constrict. Hypertrophic cardiomyopathy is a cardiac contractile-muscle disorder most often caused by genetic mutations. Symptomatic HCM treatment with beta-blockers and non-DHP calcium channel blockers i… Clinical data, ECG and echo-CG findings were assessed. In contrast to beta-adrenergic blockers, these hemodynamic effects are not associated with depression of systolic function, but appear to be related to improved left ventricular distensibility. This causes blood vessels to relax and widen (vasodilate), improves oxygen supply to the heart, and lowers blood pressure. channel blockers calcium signaling cardiomyopathy, hypertrophic, familial Sources of Funding, see page 1527 BACKGROUND: Although the genetic causes of hypertrophic cardiomyopathy (HCM) are widely … In hypertrophic cardiomyopathy, cardiomyocyte stretch is believed to increase automaticity by influencing self-depolarizing channels, such as the funny channel If and the T-type calcium channel I CaT. While useful in treating coronary artery disease and lowering blood pressure, calcium channel blockers are good for a variety of different heart conditions, including arrhythmia, diastolic heart failure, coronary spasms, chest pain (angina), hypertrophic cardiomyopathy, and coronary spasms. Calcium channel blockers used in HCM include primarily nondihydropyridine agents without significant vasodilatory properties, i.e. Clipboard, Search History, and several other advanced features are temporarily unavailable. Within this group verapamil is the drug which has been most commonly used in HCM.
