PREVALENCE, CLINICAL AND FUNCTIONAL CHARACTERISTICS OF PATIENTS WITH ACUTE MYOCARDIAL INFARCTION COMPLICATED BY ACUTE HEART FAILURE

Abstract

The aim: The study was designed to establish the prevalence of acute heart failure in patients with acute myocardial infarction, to determine the sex-age characteristics of acute myocardial infarction course in case of complications by acute heart failure of high classes (Killip III and Killip IV). Materials and methods: We analyzed medical records of inpatients of the myocardial infarction department of the municipal non-profit enterprise Vinnytsia Regional Center for Cardiovascular Pathology in 2019. The survey covered 828 medical records of patients with acute myocardial infarction, average age (64.6 ± 0.38), including 569 (64.7%) males and 311 (35.3%) females. Results: 129 (15.6%) patients with acute myocardial infarction were diagnosed high-class acute heart failure. Patients with high-class acute heart failure were statistically significantly elderly individuals of the average age (69.0 ± 1.3), (p <0.001), including 53.7% of males, and 46.3% (p <0.001) female patients. Patients with acute myocardial infarction complicated by acute heart failure were hospitalized within 2 hours of symptoms` onset with statistically significantly higher probability (p = 0.004). Patients with acute myocardial infarction complicated by acute high-class heart failure were statistically significantly more likely diagnosed with concomitant hypertension, diabetes mellitus, chronic obstructive pulmonary disease, chronic kidney disease than individuals with uncomplicated acute myocardial infarction. Acute myocardial infarction patients` mortality was 3.4%, while the one in patients with acute heart failure was 38% (p <0.001). Conclusions: Patients with complicated myocardial infarction are characterized by statistically significantly higher comorbidity and increased lethality.
