Abstract
AbstractAimsHeart failure (HF) is one of the leading causes of cardiovascular morbidity and mortality. HF with preserved ejection fraction (HFpEF), or diastolic failure, accounts for half of all HF cases and differs from HF with reduced ejection fraction (HFrEF). Patients with HFpEF are typically older, female, and commonly seen with chronic kidney disease (CKD), one of the leading independent risk factors for mortality in these patients. Unfortunately, drugs that had shown significant improvements in mortality in HFrEF have not shown similar benefits in HFpEF. Recently, sodium glucose transporter 2 inhibitors (SGLT2i) have been shown to reduce cardiovascular morbidity and mortality in HFrEF patients and slow down CKD progression. This study aimed to elucidate the impact of this drug class on mortality and risk of end stage renal disease in patients with HFpEF, which is currently unclear.Methods and resultsWe retrospectively analysed the Research Data Warehouse containing electronic health records from de‐identified patients (n = 1 266 290) from the University of Mississippi Medical Center from 2013 to 2022. HFpEF patients had an average follow‐up of 4 ± 2 years. Factors associated with increased all‐cause mortality during HFpEF included age, male sex, and CKD. Interestingly, the only treatments associated with significant improvements in survival were angiotensin converting enzyme inhibitors/angiotensin receptor blockers and SGLT2i, regardless of CKD or diabetes status. Additionally, SGLT2i use was also associated with significant decrease in the risk of end stage renal disease.ConclusionsOur results support the use of SGLT2i in an HFpEF population with relatively high rates of hypertension, CKD, and black race and suggests that improvements in mortality may be through preserving kidney function.
