[Comparative data charasteristic of laboratory examination of patients with chronic heart failure of ishemic origin with systolic left ventricular dysfunction and preserved left ventricular ejection fraction].

581 patients with chronic heart failure (CHF) of ischemic origin with systolic left ventricular dysfunction (SLVD) and preserved left ventricular ejection fraction (PLVEF) were examined. The aim of the study was to investigate the comparative aspect of laboratory examination of patients with chronic heart failure of ischemic origin with left ventricular systolic dysfunction and patients with heart failure and preserved left ventricular ejection fraction. The study found no differences in the groups on the basic parameters: the number of white blood cells, hemoglobin concentration, red blood cell count, platelet count, the number of potassium and sodium ions. At the same time, patients with CHF and left ventricular systolic dysfunction characterized by the presence of a moderate decline in glomerular filtration rate, including more frequent patients with lymphocytopenia, hypoholesteremia, hyperuricemia. For patients with chronic heart failure and preserved left ventricular ejection fraction the following characteristics have been characterized: normal or increased glomerular filtration rate, hypercholesterolemia.
