Abstract
OBJECTIVE: The aim of this study was to assess the clinical characteristics of patients with heart failure and preserved ejection fraction (HFpEF) and atrial fibrillation (AF) and compare them with those of HFpEF patients without AF. METHODS: This study was a sub-group analysis of a multicenter, observational, and cross-sectional registry conducted in Turkey (ClinicalTrials.gov identifier: NCT03026114). Patients with HFpEF were divided into 2 groups: HFpEF with AF and HFpEF with sinus rhythm (SR), and the clinical characteristics of the groups were compared. RESULTS: In a total of 819 HFpEF patients (median age: 67 years; 58% women), 313 (38.2%) had AF. Compared to the patients with SR, those with AF were older (70 years vs 66 years; p<0.001) and more symptomatic, with a higher rate of classification as New York Heart Association functional class III-IV, paroxysmal nocturnal dyspnea, orthopnea, palpitations, fatigue, pulmonary crepitations, and peripheral edema. The hospitalization rate for heart failure was higher (28.4% vs 12.6%; p<0.001) in patients with AF, and participants with AF had higher level of N-terminal pro-B-type natriuretic peptide (887 pg/mL vs 394.8 pg/mL; p<0.001) and higher left atrial volume index level. Patients without AF had a higher burden of diabetes mellitus, obstructive sleep apnea, and coronary artery disease. The prescription rate of nondihydropyridine calcium blockers, digoxin, loop diuretics, and anticoagulant drugs was higher in the AF group. CONCLUSION: The results of this study revealed that in a large Turkish cohort with HFpEF, significant clinical differences were present between those with and without AF and. Further prospective studies are needed to clarify the prognostic implications of AF in this growing heart failure population in our country.
