Abstract

Abstract. Atrial fibrillation (AF) and heart failure (HF) are closely interconnected clinical conditions associated with high prevalence among the general population, substantial morbidity, and unfavorable long-term prognosis. This literature review aims to summarize current evidence regarding clinical, electrocardiographic, echocardiographic, and laboratory predictors of incident AF across the major HF phenotypes: reduced, mildly reduced, and preserved left ventricular ejection fraction. Advanced age, arterial hypertension, diabetes mellitus, coronary artery disease, and obesity emerge as the most consistently reported clinical risk factors. Markers of atrial structural and electrical remodeling including abnormalities in P-wave indices, left atrial enlargement, and parameters of left ventricular diastolic dysfunction demonstrate significant predictive value. Biomarkers such as natriuretic peptides, galectin-3, CA-125, and inflammatory mediators further refine risk assessment by reflecting myocardial stress, fibrosis, and congestion. Although phenotype-specific determinants exist, the substantial overlap in predictors suggests a shared pathophysiological substrate underlying AF development in HF patients. Early identification of individuals at increased risk may facilitate improved risk stratification, closer surveillance, and the implementation of personalized therapeutic strategies. Future prospective studies are warranted to validate integrated predictive models and optimize clinical management in this high-risk population.
