In order to investigate the factor VIII complex trend in atherosclerosis, 96 patients suffering from atherosclerosis, divided in 6 groups (angina pectoris, previous myocardial infarction, transient ischemic attacks, previous cerebral thrombosis, diabetes without symptoms of vascular injury and diabetes with vascular complications), were studied and compared to a control group of normal subjects. Plasma levels of Factor VII Coagulant (VIII C), Factor VIII-Related von Willebrand Factor (VIII-RWF) and Factor VIII-related Antigen (VIII ARg) were measured in all subjects. A significant rise of VIII RAg was noticed in all groups of patients as compared to the control group: this increase appears to be related to the severity of vascular injury. A significant rise of VIII RWF, parallel to the VIII RAg increase, was also noticed in all groups. Besides, all groups of patients showed a significant and uniform increase of VIII C. The average ratio of VIII RAg/VIII C was raised in all groups, except diabetics without complications; but the increase was statistically significant only in those patients with a heavier vascular injury which is related to the marked rise of VIII RAg in such clinical situations. The findings of this study are discussed in relation to the literature data. The significance of the determination of VIII RAg/VIII C ratio and of the VIII RAg assay as methods for monitoring the severity of the vascular injury in atherosclerosis are also discussed.

We report a case of 47-year-old patient with von Willebrand's disease (VWD) caused by polycythemia vera (PV) who underwent CABG surgery. The patient has been suffering of PV for 10 years and was admitted because of post infarction angina. On admission, she was found to have a decreased von Willebrand factor which was suggested by prolonged APTT. CABG was safely performed without undue bleeding with the use of Factor VIII concentrates. The appropriate control of polycythemic state before surgery and perioperative use of Factor VIII concentrates was considered to be important for successful open heart surgery associated with such complication.

Coagulation is triggered during the onset of myocardial infarction, resulting in vascular occlusion. However, a causal role for individual haemostatic factors in the development of thrombotic occlusion is not established. Three cases (all relatively young women) are reported of raised factor VIII associated with myocardial infarction. Two patients presented acutely with myocardial infarction at a relatively young age with no preceding history of angina. The other patient had had venous thrombosis when young and activated protein C resistance (APCR), without the presence of factor V Leiden. A functional relation exists between APCR and factor VIII; therefore, raised factor VIII may contribute to APCR and the increased thrombotic risk in patients without factor V Leiden. Factor VIII is an important risk factor for atherothrombotic events, including sudden death, in patients with vascular disease. These cases support the association of raised factor VIII with acute thrombotic events, even in patients without significant underlying atheromatous disease.

Little is known about the prospective associations of fibrinogen, factor VII, or factor VIII with cardiovascular disease (CVD) and mortality in the elderly. At baseline in the Cardiovascular Health Study (5888 white and African American men and women; aged >/=65 years), we measured fibrinogen, factor VIII, and factor VII. We used sex-stratified stepwise Cox survival analysis to determine relative risks (RRs) for CVD events and all-cause mortality (up to 5 years of follow-up), both unadjusted and adjusted for CVD risk factors and subclinical CVD. After adjustment, comparing the fifth quintile to the first, fibrinogen was significantly associated in men with coronary heart disease events (RR=2.1) and stroke or transient ischemic attack (RR=1.3), and also with mortality within 2.5 years of follow-up (RR=5.8) and later (RR=1.7). Factor VIII was significantly associated in men with coronary heart disease events (RR=1.5) and mortality (RR=1.8), and in women with stroke/transient ischemic attack (RR=1.4). For both factors, values were higher in those who died, whether causes were CVD-related or non-CVD-related, but highest in CVD death. Factor VII exhibited associations with incident angina (RR=1.44) in men and with death in women (RR, middle quintile compared with first=0.66). However, in general, factor VII was not consistently associated with CVD events in this population. We conclude that, if confirmed in other studies, the measurement of fibrinogen and/or factor VIII may help identify older individuals at higher risk for CVD events and mortality.

Plasma levels of haemostasis factors (HFs) such as fibrinogen, tissue-type plasminogen activator (t-PA), plasminogen activator inhibitor-1 (PAI-1) and D-dimer may be markers of arteriosclerosis for the following reasons: There seems to be no difference in levels of HFs between patients with longstanding stable angina and those with an isolated myocardial infarction. HF levels are generally positively associated with subclinical arteriosclerosis as determined by ankle-arm index and carotid ultrasonography in asymptomatic individuals. Levels of most HFs are positively associated with inflammation, which is an essential part of the initiation and progression of the disease. A rough classification is assigned to the associations found in under (2) and (3). Fibrinogen is strongly associated with subclinical arteriosclerosis and with inflammation; Factor VII is not, while an intermediate group is formed by, for instance, von Willebrand Factor (vWF), Factor VIII (F VIII), t-PA, PAI-1, and D-dimer. Also, the associations of HFs with cardiovascular events follow a similar pattern. Fibrinogen is a strong and consistent risk factor in several studies, Factor VII is not, and a similar intermediate group as mentioned under (2) and (3) exists. It suggests that the risk of cardiovascular events in relation to HF levels is explained by their identity as markers of arteriosclerosis. A causal association between HF levels and the disease is not proven. Out of the HF, the markers of coagulation such as thrombin-antithrombin complex and of fibrinolysis such as D-dimer are more likely to act causally. Increased levels indicate that they are markers of arteriosclerosis, but in addition, they may reflect a low-grade, continuous formation and subsequent lysis of fibrin in the disease. As the latter reflects an increased tendency to thrombosis, a causal association of levels of markers of coagulation and fibrinolysis with arteriosclerosis, although not yet proven, seems likely.

Thrombophilia-hypofibrinolysis may play an important role in rare premature (< or = age 45 years) arterial occlusive events in atherothrombotic cardiovascular (ATCVD) disease, particularly in normolipidemic patients. Whether thrombophilia-hypofibrinolysis contributed to ATCVD < or = age 45 years was assessed in 78 men and 40 women with 230 ATCVD events (myocardial infarction (MI) [n = 60], coronary artery bypass graft [CABG, n = 33], angioplasty [n = 52], chronic angina [n = 41], ischemic stroke [n = 11], transient ischemic attack [TIA, n = 24], claudication [n = 9]). Cases were compared with healthy normal adult controls (44 men and 76 women). In men, the Factor V Leiden mutation was present in 6/63 (10%) cases versus 0/44 (0%) controls (P = 0.042), Factor VIII was high (>150%) in 16/60 (27%) cases versus 1/42 (2%) controls (P = 0.001), Factor XI was high (>150%) in 9/57 (16%) cases versus 0/42 (0%) controls (P = 0.009), and plasminogen activator inhibitor activity (PAI-Fx) was high (>21.1 U/mL) in 15/63 (24%) cases versus 3/43 (7%) controls (P = 0.023). In women, protein C was low (<73%) in 4/26 (15%) cases versus 0/74 (0%) controls (P = 0.004), and free protein S was low (<66%) in 5/27 (19%) cases versus 2/74 (3%) controls (P = 0.014). In women, Factor XI was high (>150%) in 3/27 (11%) cases versus 1/74 (1%) controls (P = 0.057), and the lupus anticoagulant was present in 9/32 (28%) cases versus 2/51 (4%) controls (P = 0.002). In patients with ATCVD < or = age 45 years, thrombophilias (Factor V Leiden, Factor VIII, Factor XI, protein C and S deficiency, lupus anticoagulant) and hypofibrinolysis (PAI-Fx, Lp[a]) may promote arterial thrombosis, which is synergistic with atherosclerotic endothelial injury.
