Antianginal drug therapy for silent myocardial ischemia

Many of the available nitrate preparations, beta-adrenergic blockers, and calcium antagonists appear to be useful in patients with painful and silent ischemic episodes detected on the ECG (Table 1). More controlled studies need to be done using standardized methodologies for assessing silent myocardial ischemia, to evaluate and compare the different antianginal medications. It is fortunate, however, that the nitrates, beta-blockers, and calcium antagonists, used alone and in combination, appear to have favorable effects not only on painful ischemic episodes but also on those ischemic episodes not associated with pain.
