Abstract
Reduced left ventricular ejection fraction (LVEF) is common in hemodialysis (HD) patients. Lipoprotein-associated phospholipase A2 (Lp-PLA2) is considered an important determinant of cardiovascular events. The aim of the study was to evaluate the relationship between Lp-PLA2 and LVEF in HD patients. Fifty-seven HD patients with coronary heart disease were enrolled. Predialysis and postdialysis venous whole blood samples were collected. The patients were divided into preserved and reduced LVEF groups. The relationship between Lp-PLA2 and LVEF was assessed. A significant difference in C-reactive protein (CRP) and Lp-PLA2 was observed, with higher levels noted in patients with reduced LVEF (P≤.001). Both Lp-PLA2 and CRP were negatively correlated with LVEF in the HD patients. Only Lp-PLA2 remained associated with LVEF in multiple regression analysis. Lipoprotein-associated phospholipase A2 levels are associated with LVEF and could potentially be used to evaluate chronic heart failure with reduced LVEF in HD patients for risk stratification management.
