Calcium channel blockers are potent and widely used antihypertensive drugs. They act by preventing calcium entry through voltage-gated calcium channels, predominantly the L-type, into cells resulting in the relaxation of vascular smooth muscle. They dilate arteries and arterioles that increase end-organ perfusion and exhibit a few adverse effects especially in the elderly hypertensive patients. The safety of calcium channel blockers is well established. Clinical trials have established non-inferiority of calcium channel blockers as compared to angiotensinconverting enzyme inhibitors, angiotensin-II AT 1 receptor blockers, and diuretics for the prespecifi ed cardiovascular endpoints. Calcium channel blockers can manifest blood pressure-independent cardiovascular protection, but this effect largely depends on their effi cacy to lower blood pressure including that of central blood pressure. Calcium channel blockers are essential antihypertensive drugs to reach goal blood pressure and thus the treatment of choice (although not always the fi rstline agent) for most hypertensive patients, especially for the high-risk population and those with resistant hypertension. An intense treatment of hypertensive patients with adequate doses of calcium channel blockers is mandatory to improve cardiovascular prognosis. In this chapter, important clinical evidence to support the effi cacy of calcium channel blockers to improve cardiovascular endpoints will be reviewed.
