Abstract

Background The European Society of Cardiology has recently defined heart failure (HF) patient group with a left ventricular ejection fraction (LVEF) of 41-49% as a different category with the term heart failure with mildly reduced ejection fraction (HFmrEF). In this study, we aimed to conduct a research about the correlation between left atrial volume index (LAVI) and atrial fibrillation in patients HFmrEF. Methods A total of 282 patients HFmrEF who were admitted to the cardiology department from three different centres were included in the study. The study was planned as multicenter, cross-sectional study. The patients were divided into two groups as sinus rhythm and atrial fibrillation based on their electrocardiographic findings. Results It was found out that Nt-ProBNP, LA area, LAVI, pulmonary artery pressure, and severe mitral regurgitation rates were significantly higher in the AF group (p < 0.001). ROC analysis resulting in LAVI > 30.5 had 64% sensitivity and 66% specificity in the predicting presence of AF (ROC area under the curve: 0.660, 95% CI: 0.587-0.733, p < 0.001). We also observed that the LA area being >16.55 predicting presence of AF with 60% sensitivity and 58% specificity (ROC area under the curve: 0.624, 95% CI: 0.549-0.699, p = 0.002). Conclusion In the study conducted, we found a correlation between AF and LAVI values in patients in the HFmrEF group. If the LAVI value increases in the follow-up of this group of patients with echocardiography, close follow-up in terms of AF may allow the early control and treatment of AF-related incidents.
