title: [Thrombophilic state inpatients suffering from myocardial infarction with or without carotid atherosclerotic lesions].
abstract: The aim of the present study was to evaluate some metabolic, coagulation and fibrinolytic parameters in 35 patients (24 males and 11 females, mean age 57 +/- 4 years) suffering from myocardial infarction more than 6 months before with or without carotid atherosclerotic lesions. After evaluation by B-mode duplex scanning system of extracranial carotid arteries, the patients were subdivided into two groups: Group 1 (n = 16, with carotid plaques or intima-media thickening) and Group 2 (n = 19, without carotid plaques or intima-media thickening). Eighteen age- and sex-matched subjects were recruited as controls (Group 3). Groups 1 and 2 displayed significantly higher levels of total cholesterol and apolipoprotein B and significantly lower levels of HDL-cholesterol and apolipoprotein A1 than Group 3, while serum triglyceride and lipoprotein (a)-Lp (a) levels were significantly higher in Group 1 as compared to the control group. Moreover, Group 1 and 2 displayed significantly higher levels of factor VII, fibrinogen, F1+2, thrombin-antithrombin complex and plasminogen activator inhibitor (PAI) post venous occlusion and significantly lower levels of tissue plasminogen activator (t-PA) post venous occlusion than Group 3. Significantly higher levels of t-PA and PAI pre venous occlusion and significantly lower levels of antithrombin III, C-protein and S-protein were observed in Group 1 as compared to controls. In patients with highest Lp(a) level, the lowest t-PA level post venous occlusion and the highest PAI level post venous occlusion were observed. Our data show an activation of coagulation and a deficient fibrinolysis in survivors of myocardial infarction, particularly in those with associated carotid atherosclerotic lesions. We speculate that this thrombophilic state may play a key role in the pathogenesis of atherosclerotic vascular disease and thromboembolic complications.
