[Gender differences in the state of the system of hemostasis in patients with ischemic heart disease]

Abstract

Levels of fibrinogen, von Willebrand factor, d-dimer, antithrombin III, protein C, plasminogen, and plasminogen activator inhibitor were measured in 62 men and 37 women with ischemic heart disease before and after 20-min venous occlusion. Women compared with men had higher baseline levels of fibrinogen (4.046-/+0.1785 and 3.584-/+0.1591 g/l, respectively, p=0.021), von Willebrand factor (122.1-/+9.31 and 99.5-/+6.16%, respectively, p=0.035), plasminogen activator inhibitor (4.8-/+0.31 and 2.9-/+0.27 IU/l, respectively, p=0.009). Levels of antithrombin III, protein C, and plasminogen in women were higher than in men both at baseline (108.5-/+1.65 and 100.7-/+1.60 %, p=0.001; 129.1-/+2.91 and 107.2-/+3.79%, p=0.001; 113.6-/+2.13 and 104.1-/+1.89%; p=0.001, respectively) and after venous occlusion. There were no gender differences in dynamics of parameters of hemostasis during venous occlusion. Multifactorial regression analysis showed that gender was independently (of age, duration of hypertension, smoking, body mass index, and total cholesterol level) related to only antithrombin III and protein C levels.
