Abstract
The aim of the study was to assess MMP-2 (matrix metalloproteinase-2) and TIMP-2 (tissue inhibitor of metalloproteinase-2) serum levels in patients with diverse types of heart failure (HF) and chronic kidney disease (CKD).101 patients with chronic HF were enrolled. Each patient has assessed the serum levels of MMP-2, TIMP-2, and NT-proBNP. Patients were initially classified into 2 groups based on their LVEF. 43 patients were classified into the HFREF group (HF with Reduced Ejection Fraction) and 58 characterized as HFPEF (HF with Preserved Ejection Fraction). Next, all patients were subdivided into 4 groups according to the degree of diastolic dysfunction.38 patients with CKD were classified into HF/CKD(+) group. The HF/CKD(-) (HF without CKD) group comprised 61 patients.This study provides original data on positive correlation between ejection fraction and MMP-2 levels in all patients with heart failure. Elevated levels of MMP-2 and TIMP-2 were found in serum from patients with chronic kidney disease; in addition, serum levels of MMP-2 were correlated with the degree of kidney failure. In all groups of patients there was positive correlation between MMP-2 and TIMP-2. Among patients with heart failure etiology was not related to MMP-2 and TIMP-2 serum levels.
