Gender features of structural and functional changes of the heart and levels of copeptin and NTproBNP in patients with acute Q-myocardial infarction in the presence of pulmonary hypertension

Abstract

The aim. To evaluate the gender features of structural and functional changes in the heart and levels of copeptin and NTproBNP in patients with acute myocardial infarction (AMI) with concomitant pulmonary hypertension (PH). Materials and methods. 74 patients with AMI and concomitant PH who were treated in the intensive care unit and emergency cardiology for patients with myocardial infarction of the Municipal Non-Profit Enterprise “City Hospital of Emergency and Ambulance” of Zaporizhzhia City Council were examined. The patients were divided into two groups: the first group consisted of 42 male patients (mean age 71.06 ± 2.21 years) and 32 female patients (mean age 76.41 ± 2.32 years). All the patients were examined in the first three days by two-dimensional echocardiography on a device MyLab50 (“Esaote”, Italy). The serum levels of kopeptin and NTproBNP were determined by enzyme-linked immunosorbent assay using a set of reagents Elabscience (USA). Results. There was a trend towards a predominantly anterior AMI in the group of men and lower AMI – in the group of women. Individuals with functional class III and IV heart failure predominated (76.1 %) among the men with AMI and PH. At the same time, there were significantly more persons with III and IV functional class in the group of men than in the group of women (P < 0.05). There was a significant diastolic left ventricular posterior wall thickening in women compared to men (8.4 %; P < 0.05) and a tendency to diastolic interventricular septal thickening in females. There was an upward trend in end-systolic and end-diastolic sizes in the group of men compared to women; however, the differences did not reach the required level of significance. Evaluation of serum copeptin and NTproBNP in patients with AMI and PH revealed significantly higher levels of these indicators in the group of men compared to women (P < 0.05). Conclusions. Men with AMI and PH had more severe heart failure compared to women due to the predominance of patients with functional classes III and IV. Women with AMI and PH demonstrated predominantly concentric type of remodeling in the form of significantly thickened LV posterior wall and the tendency to increase interventricular septum wall thickness, and eccentric hypertrophy in the form of LV dilatation prevailed in men. Men with AMI and PH had significantly higher serum copeptin and NTproBNP levels compared to women.
