title: Increased plasminogen activator inhibitor activity in survivors of myocardial infarction is associated with metabolic risk factors of atherosclerosis.
abstract: To assess the relationship between the fibrinolytic system and coronary risk factors, several fibrinolytic parameters were measured in 72 male survivors of myocardial infarction and in 53 age-matched healthy controls. The coronary patients had significantly higher plasminogen activator inhibitor (PAI) activity than the control subjects, while t-PA antigen did not differ between the groups. After stratifying the coronary patients in 14 diabetic and 58 nondiabetic patients, the elevated PAI activity remained limited to the diabetic group. PAI activity correlated significantly with systolic blood pressure, blood glucose, body mass index and LDL cholesterol. In multivariate regression analysis, significant associations persisted between PAI and diabetes, body mass index and LDL cholesterol. Coronary disease had no impact on the regression model. Our results suggest that the increased PAI-1 in selected groups of coronary patients is not a consequence of coronary disease itself, but is rather related to the metabolic risk factors of atherosclerosis, especially diabetes.
