[Platelet aggregation and plasma lipid spectrum in patients with myocardial infarct developing on the background of first-time appearing angina pectoris].

Patients with myocardial infarction in the presence of first angina pectoris have been found to display less platelet aggregability in the acute period of the disease than those with recurrent myocardial infarction, which is associated with a lower incidence of postinfarction complications and smaller plasma triglyceride levels. The changes observed in plasma lipid concentrations and platelet aggregation in different periods of the disease have been shown to be similar to those seen in patients with myocardial infarction concurrent with sustained angina.
