Cardiac safety in the European Stroke Prevention Study 2 (ESPS2).

The second European Stroke Prevention Study investigated the prevention of stroke and/or death in 6602 patients with transient ischaemic attack or stroke with aspirin (25 mg b.d.), dipyridamole (400 mg b.d.), the combination of aspirin and dipyridamole or placebo. This post hoc analysis investigated cardiac events in patients with coronary heart disease or myocardial infarction (MI) at entry. Dipyridamole did not result in a higher number of cardiac events, e.g. angina pectoris, MI, or death from all causes. The combination of aspirin plus dipyridamole was superior to either drug alone in the prevention of stroke.
