Abstract

The aim of current study was to investigate the level of Myeloperoxidase (MPO) in chronic heart failure patients with different severity and find the correlation with cardiac structural and functional markers and disease outcome. Initially eighty-six patients with different stages of CHF and ten healthy persons were included in our study. Excluded criteria were myocardial infarction or other concomitant acute diseases, renal failure (creatinine >250 µmol/L) in past 3 months. All patients underwent ECG, echocardiographic evaluation, anthropometric and other clinical examination, as well as plasma samples were collected for further analysis. MPO level (ng/ml) was measured by ELISA method, hs-CRP (mg/L) was measured by turbidimetric immunoassay and Leukocyte level (109/L) - by flow cytometry. Echocardiographic studies were performed using standard methods by parasternal and apical view. Statistical analyses were performed using IBM SPSS Statistics 16.0. After 6 month follow up we investigate our research primary outcome (mortality). The data were collected by telephone follow up from patients or members of family. Collection of information had been became possible in 79% of total cases (68 patients), from which 10 patients died: 8 cases were cardiovascular mortality, 1 case - suicide and 1 case from cancer. We found that MPO levels in the patients with CHF (mean value 9.3±7) are different from control group (mean value 4.19±2). MPO correlates with HF severity. MPO significantly were elevated in mortality group p<0,007 , as the level of hs-CRP p˂ 0.001. Changes of RV (right ventricule) sizes from normal ranges also were associated to worse outcome ( p<0.005). Depending on our data certain level of MPO (˃7.1 ng/ml) in studied patients and increased RVDD have independent importance for identification of patients with worse outcome.
