Prevalence dynamics, sex-age characteristics and mortality in acute heart failure in patients with myocardial infarction

Abstract

Annotation. Acute heart failure (AHF) is a major cause of death and/or reduced quality of life in patients with acute myocardial infarction (MI). Purpose: to assess the dynamics of the prevalence of severe AHF (Killip III, Killip IV) in the patients with acute MI over a five-year period at specialized center for medical care for the patients with myocardial infarction. The study is a retrospective analysis of medical records of acute MI patients over 5 years. Statistical analysis of the results was performed using a software package in the system “Statistica 7.0” (Statsoft.Inc., USA). We used parametric methods (Student’s t-test), non-parametric statistics (Mann-Whitney U-test) and non-parametric Spearman correlation analysis. It is established that the prevalence of AHF in patients with acute MI averages 12.1 %. In the structure of AHF were prevalence of men over women however, in 2019 the ratio of men and women did not differ significantly. Predominant the patients older than 70 years. Mortality of AHF patients on the background of acute MI for a 5-year period is 40.8 %. There is a positive correlation of AHF with Q-MI (r=0.22, p=0.002), concomitant arterial hypertension (r=0.19, p=0.007), diabetes mellitus (r=0.18, p=0.011) and heart rates disorders (r=0.30, p<0.001). The inverse correlation was determined between AHF and hospitalization time more than 24 hours (r= -0.17, p=0.002) and non-Q MI (r= -0.19, p<0.001).
