Abstract

Patients on hemodialysis (HD) are prone to atherosclerotic cardiovascular complications. In an attempt to determine the significance of several atherosclerotic and thrombogenic parameters as risk factors for atherothrombotic cardiovascular disease (CVD) in these patients, we compared two groups of non-diabetic HD patients matched for age and sex, selected according to the absence (group 1, n = 30) or presence (group 2, n = 30) of symptomatic atherothrombotic vascular disease affecting the coronary, cerebral, or peripheral arteries. Duration of HD, primary renal disease (PRD), presence of hypertension, EPO treatment, and smoking habits were recorded. Serum total cholesterol (TC), triglycerides (TG), HDL-C, LDL-C, TC/HDL-C ratio, lipoprotein(a) (Lp(a)), fibrinogen (FG), plasminogen (PLG), fibronectin (FN), and hematocrit (HCT) were measured pre-HD in a midweek session. The same blood parameters were also assessed in twenty matched clinically healthy subjects (controls). None of the blood parameters differed between groups 1 and 2, except for serum Lp(a) and FN, which were higher in group 2 (p = 0.005 and p = 0.041, respectively). Both groups were not different regarding PRD, duration of HD, and EPO treatment, but the presence of hypertension and smoking habits were more common in group 2 (p = 0.008 and p = 0.045, respectively). Moreover, multiple stepwise logistic regression analysis with Lp(a), FN, hypertension, and smoking showed that the presence of hypertension (p = 0.016) and the Lp(a) (p = 0.027) and FN (p = 0.024) levels, but not smoking, were independent predictors for the presence of atherothrombotic CVD. Our results suggest that hypertension, abnormal lipid particles, and thrombogenic proteins may contribute to the high prevalence of CVD in HD patients.
