Prinzmetal's angina is caused by coronary artery spasm. Calcium channel blockers (e.g.,diltiazem,amlodipine [Norvasc])are a first-line therapy for this type of angina. Lipid-lowering drugs help reduce atherosclerosis (i.e.,plaque formation),and b-adrenergic blockers decrease sympathetic stimulation of the heart (i.e.,palpitations). Medications or activities that increase myocardial contractility will increase the incidence of angina by increasing O? demand.
