Thirty-seven patients affected by spontaneous angina and 15 comparable control subjects were enrolled in a 12-month prospective study to evaluate the relationship between blood clotting activation (assessed by fibrinopeptide A [FPA] plasma concentration) and the occurrence of myocardial ischemic attacks. FPA measurements and clinical examinations in patients were performed every 2 weeks. In control subjects blood sampling was performed every 4 weeks. Data from 28 patients who completed the study and from the 15 control subjects were analyzed. The clinical activity of angina was divided into three classes (asymptomatic, mildly symptomatic, and severely symptomatic) on the basis of the number and time-concentration of the ischemic attacks and ECG changes during the 15 days preceding each clinical examination. In all but one patient, a cyclic pattern of activity of coronary artery disease was observed. During follow-up studies, 624 FPA measurements were performed in patients and 173 in control subjects. Mean values were 4.68 +/- 4.53 and 1.32 +/- 0.60 ng/ml, respectively (p less than 0.001). FPA levels differed markedly in relation to the activity of angina. A relationship between FPA levels and activity of disease (r = 0.54, p less than 0.01) was found in time course. Bolus heparin administration (100 IU/kg) during the active phase of angina sharply but incompletely lowered FPA plasma levels, indicating thrombin formation both intravascularly and extravascularly. Present results indicate that a marked blood clotting activation occurs simultaneously with the outbursts of clinical activity of spontaneous angina.
