Calcium channel blockers reduce myocardial oxygen demands by depression of contractility, HR, and/or decreased arterial BP.7 Myocardial oxygen supply may be improved by dilation of coronary and collateral vessels. Calcium channel blockers, which block norepinephrine-mediated calcium transport into vascular smooth muscle, have been used successfully at several medical centers to preoperatively prepare patients with Calcium channel blockers (CCBs) are medications used in the treatment of a variety of heart conditions and high blood pressure.

Although they have generally been effective and well tolerated, recent concerns about their safety await the results of well designed, long term clinical trials currently underway. Calcium channel antagonists block the slow calcium channels in the myocardium and vascular smooth muscle, leading to coronary and peripheral vasodilation.Table 150-4 -- Selected Characteristics of Some Calcium Channel Blockers.

Doses of calcium channel blockers used in treating hypertension are similar to those used in treating angina. Some epidemiologic studies reported an increased risk of myocardial infarction or mortality in patients receiving short-act-ing nifedipine for hypertension.
