Any heart failure treatments associated with worsening renal function in patients admitted due to acute heart failure?

Abstract

Background: Worsening renal function (WRF) occurs in approximately 25% of acute heart failure patients, and both baseline characteristics and heart failure treatment may increase the risk of WRF. This study aimed to evaluate additional risk factors for WRF in acute heart failure, particularly those related to heart failure treatment. Methods: This was a retrospective, observational, analytical study. The inclusion criteria were age 18 years or over, hospital admission due to acute heart failure, and having undergone at least two serum creatinine tests during admission. The eligible patients were classified into two groups: WRF and non-WRF. Predictors for WRF (including treatment parameters) were determined using logistic regression analysis. Results: During the study period, there were 301 eligible patients who met the study criteria. Of those, 82 (27.24%) had WRF. There were two independent factors associated with WRF occurrence: baseline diastolic blood pressure and beta blocker treatment, with adjusted odds ratios (95% confidence interval) of 1.060 (1.008, 1.114) and 0.064 (0.006, 0.634), respectively. The Hosmer-Lemeshow Chi square for the final model was 6.11 (p =.634). Conclusions: After examining several heart failure treatments and baseline factors, we found that beta blocker treatment results improvement in kidney function. © 2021 The Author(s).
