Abstract:

Objective To investigate the clinical characteristics and readmission risk factors of patients with ejection fraction preserved heart failure (HFpEF) and atrial fibrillation (AF). Methods The clinical data of 459 patients with HFpEF hospitalized at the Hebei General Hospital from June 2018 to May 2020 were retrospectively analyzed, and they were allocated to AF group (n=242) and sinus rhythm (SR) group (n=217) based on the presence or absence of AF during hospitalization. The clinical data of the two groups were compared, the clinical characteristics of patients with HFpEF and AF were analyzed; further, the readmission risk factors were discussed. Results Compared with those of the SR group, patients in the AF group presented significantly older age, lower proportion of smokers, body mass index (BMI), systolic blood pressure (SBP), proportion of comorbidities of hyperlipidemia and ischemic cardiomyopathy, and proportion of using neprilysin inhibitors, calcium antagonists and antiplatelet drugs, andhigher proportion of comorbidities of somatization disorder and heart valve disease, left ventricular end-systolic diameter, pulmonary artery systolic pressure, B-type natriuretic peptide, left and right atrium diameter, right ventricular diameter, and proportion of using anticoagulant and digitalis(all P<0.05). Univariate and multivariate logistic regression analysis showed that somatization disorder, type 2 diabetes, hyperuricemia, β-blockers were independent risk factors for readmission in patients with HFpEF and AF. Conclusion There were significant differences in clinical profiles between HFpEF patients with and without AF. The comorbidities such as type 2 diabetes, hyperuricemia, and the somatization disorder may be risk factors for readmission in patients with HFpEF and AF, whereas β-blockers may be an independent protective factor for it.
