CLINICAL AND EPIDEMIOLOGICAL PARALLELS OF HEART FAILURE AND ATRIAL FIBRILLATION

SUMMARY. The aim – to assess the prevalence of HF in patients with AF. Material and Methods. The study was performed on the basis of the regional clinical hospital (Odesa) in 2018–2021. Medical records of 2459 patients with HF were retrospectively studied. All patients were examined in accordance with the Unified Protocol of Medical Care, Order of the Ministry of Health of Ukraine No. 384 (2012). All patients were assessed for exercise tolerance using a 6-minute walk test. Statistical processing was performed by methods of analysis of variance and correlation. Results. The average age of patients was 64.3–1.9 years, In 2.2 % of patients under the age of 60 was found AF, whereas amongst older patients there were 13.3 % cases. Ist FC CH was in 34 (65.4 %) patients, III FC CH – in 34.6 %. The average test score with a 6-minute walk was 277.5±12.5 m, the average time of restitution after exercise – 32.3±3.7 s. The average score on the CHADS-VASC scale was 4.2±0.3 points, HAS-BLED – 2.9±0.2 points. The results of 6-minutes walking test correlated with the duration of AF (r=-0.66). Conclusions.1. There were 2.2 % of patients under the age of 60 had AF, in older patients – in 13.3 % of cases. The constant form of AF is the most often noted variant. Inverse correlation between the distance traveled by the patient in 6 minutes and the duration of AF (r=-0.66) was found.
