In acute coronary events, plaque rupture and the subsequent formation of the catalytic tissue factor-factor VIIa complex is considered to initiate coagulation. It is unknown whether clotting factors XI and IX are activated in acute coronary events. Therefore, we prospectively investigated the activation of clotting factors XI and IX as well as activation of the contact system and the common pathway in 50 patients with acute myocardial infarction (AMI), in 50 patients with unstable angina pectoris (UAP), and in 50 patients with stable angina pectoris (SAP). Factor XIa-C1 inhibitor complexes, which reflect acute activation of factor XI, were detected in 24% of the patients with AMI, 8% of the patients with UAP, and 4% of the patients with SAP (P<0.05), whereas factor XIa-alpha(1)-antitrypsin complexes, which reflect chronic activation, were observed equally in all 3 study groups. Factor IX peptide levels were significantly higher in the patients with AMI and UAP compared with the patients with SAP (P<0.01). No differences regarding markers of the common pathway were demonstrated. Fibrinopeptide A levels were elevated in patients with AMI compared with patients with UAP and those with SAP (P<0.01). Factor XIIa- or kallikrein-C1 inhibitor complexes were not increased. In conclusion, this is the first demonstration of the activation of clotting factors XI and IX in patients with acute coronary syndromes. Because these clotting factors are considered to be important for continuous thrombin generation and clot stability, their activation might have clinical and therapeutic consequences.

The aim of this study was to search for the factors favouring the revealing of a coronary artery disease by comparing selected lipids and carbohydrate parameters between two groups--younger and older men with coronary artery disease. Into the study were included 60 men with stable angina confirmed by coronarography (at least 6 months after CABG, PTC A or myocardial infraction, with EF > 40%) and 33 men without atherosclerotic changes in the coronary vasseles as the control group. The two groups were divided depending on age: the younger subgroup [(under 60-ty years old-group: A with CAD, n = 30) and (B without CAD, n = l8)] and older subgroup [(over 70 years old-group: C with CAD, n = 30) and (D without CAD, n = 15)]. Men of middle age were not included. Serum semples were analyzed for the concentration of lipids parameters including apolipoprotein AI and B. The oral glucose tolerance test was carried out for all patients. In control groups (B and C) in comparison to the groups with CAD (A and C) was observed significantly higher concentration of the HDL cholesterol (by abouth 28% in younger men and 16% in older men (r with CAD = 0.40) and ApoAI (respectively by about 17% and 12.5%, r = 0.47). Weak, but positive corelation with the presence of coronary heart disease was shown for fasting glucose concentration. The younger and older men with CAD (A vs C) statistically significantly differed in concentration of HDL (a.v. 9.1 +/- 6.2 vs 46.7 +/- 11,7 ng/dl) and strongly correlated with HDL ApoAI (av. 137.6 +/- 12.6 vs 146.6 +/- 21.5 ng/dl). The negative family history was more often in younger patients.
