[Hemostatic factors and family history of thrombosis in patients with a myocardial infarct: a case-control study. The participants in GISSI-2-Efrim. Gruppo Italiano per lo Studio della Streptochinasi nell'Infarto Miocardico].
We studied a series of hemostasis factors in a group of patients selected from a cohort of 916 patients affected by MI from the GISSI-2 study population. Following a case-control design, 73 patients with a family history of thrombosis (the presence of at least two first degree relatives affected by MI and/or stroke before 65 years) were matched with MI patients with no family history of thrombosis. Blood collection could be performed 6 +/- 1 months after the acute phase following MI in 53 pairs of such patients. The presence of mixed disulphides (MDS) was significantly higher in patients with family history than in controls; MDS were detected in 7 cases and only in 1 control. No difference was found in contrast in the distribution of fibrinogen, factor VII, factor VIII, vWF, protein C, protein S, AT III, HC II, PAI-1, lipoprotein (a). Nevertheless, independently from the family history, in the whole population of MI patients studied, 21 cases of suspected deficiency of protein C were found. Sixteen out of 53 patients with family history of MI and/or stroke had a family history of MI only. In patients with family history of MI the t-PA antigen levels were significantly lower than in the control group (7.5 +/- 4.4 vs 11.1 +/- 3.5 ng/ml, t = -2.6, p < 0.02). In the whole population of MI patients and in patients with a family history of thrombosis t-PA antigen was positively correlated with PAI-1 antigen and vWF. The correlation with PAI-1 was lost in patients with family history of MI.(ABSTRACT TRUNCATED AT 250 WORDS)
