[Calcium channel blockers in the treatment of cardiovascular disease].

Drugs classified as calcium channel blockers (CHBs) are now among the most frequently prescribed drugs for the treatment of cardiovascular disease. Although the currently available CCBs have major differences in their structural and cardiovascular effects, they share the common property of blocking the transmembrane flow calcium ions through voltage gated L-type channels. These drugs have been approved for the treatment of hypertensive heart disease: they reduce left ventricular hypertrophy and improve its sequelae, such as ventricular dysrhythmias, impaired filling and contractility, and myocardial ischemia. Long-acting CCBs have been shown to reduce mortality and morbidity in elderly patients with systolic hypertension, appear to be extremely useful in patients with cyclosporin-induced hypertension, and can be used as alternatives to ACE inhibitors in patients with hypertension and concomitant diabetes mellitus, renal disease, Raynaud's phenomenon or migraine. Long-acting dihydropyridine have been shown to be effective and safe in the treatment classic angina pectoris and vasospastic angina, supraventricular arrhythmias, particularly reentrant AV-nodal tachycardia, others to be beneficial in patients with congestive heart failure, and all of them have potential for decreasing atherogenesis.
