ABSTRACT
BACKGROUND:
Heart failure with preserved ejection fraction (HFpEF) with renal dysfunction (RD) is considered to be a specific phenotype of HFpEF. This study aimed to compare the clinical characteristics and prognostic factors for in-hospital mortality between HFpEF-diagnosed patients with and without RD.METHODS:
This multicenter retrospective study included 5867 consecutive patients with acute HFpEF. RD was defined by an estimated glomerular filtration rate (eGFR) of <60 mL/min per 1.73 m2. Kaplan-Meier survival curves and log-rank tests were used to compare the in-hospital mortality between the groups. Univariable and multivariable Cox regression analyses were performed to identify significant prognostic factors.RESULTS:
Across the study cohort, 68% of patients had RD. In-hospital mortality was significantly higher in HFpEF patients with RD than in those without RD. The comorbidities and laboratory data differed significantly between the groups. Independent prognostic factors for in-hospital mortality in the HFpEF patients with RD were age (hazard ratio [HR], 1.039), systolic blood pressure (HR, 0.991), eGFR (HR, 0.981), C-reactive protein (CRP; HR, 1.028), diuretics (HR, 0.374), angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers (ACE-I/ARBs; HR, 0.680), and beta-blockers (HR, 0.662). In HFpEF patients without RD, age (HR, 1.039), systolic blood pressure (HR, 0.979), and ACE-I/ARBs (HR, 0.373) were independent prognostic factors.CONCLUSIONS:
Significant differences in the clinical characteristics and prognostic factors, such as CRP and beta-blockers, were observed between the HFpEF patients with and without RD. These results have implications for future research and may help guide individualized patient management strategies.
