ABSTRACT
We examined activities or levels of plasmin and thrombin inhibitors in essentially untreated patients with angiographically documented coronary artery spasm. The patients received the ergonovine malate provocation test and were classified into two groups (a) those with significant coronary artery spasm that produced reduction of the internal luminal diameter of 50% or greater with chest pain and change of electrocardiography (n = 18), and (b) those without coronary artery spasm (n = 17). There was no significant differences in alpha 1-antitrypsin and alpha 2-macroglobulin levels, and C1-inactivator activity between the control and patients with coronary artery spasm. On the other hand, the lower antithrombin III and alpha 2-plasmin inhibitor activities were noted in patients with coronary artery spasm than the control. Thrombin/antithrombin III complex and alpha 2-plasmin inhibitor/plasmin complex levels were significantly higher in coronary artery spasm patients. These results suggest that the coagulation and fibrinolytic systems may maintain their equilibrium in untreated patients with coronary artery spasm.
