Do tissue plasminogen activator and plasminogen activator inhibitor levels predict death and non-fatal cardiovascular events in patients with severe angina pectoris?
High tissue plasminogen activator antigen concentration is a predictor of increased risk for cardiovascular events in patients with severe angina pectoris.
The value of measurements of the fibrinolytic factors, tissue plasminogen activator and plasminogen activator inhibitor, for predicting death and non-fatal cardiovascular events was studied in 213 consecutive patients with angiographically documented coronary artery disease. In the course of 4-year follow-up, 47 patients (22.1%) had at least one cardiovascular event. We found the incidence of cardiovascular events to be positively associated with high tissue plasminogen activator antigen concentration, in addition to previous myocardial infarction, low ejection fraction, hypertension, high body mass index and high triglyceride levels. Cholesterol was not found to be associated with cardiovascular events. A high concentration of tissue plasminogen activator antigen thus implies an increased risk of cardiovascular events in patients with severe angina pectoris.
