Efficacy of Sodium-Glucose 2 Transporter Inhibitors in Heart Failure With Preserved Ejection Fraction: A Narrative Review
Abstract
Heart failure with preserved ejection fraction (HFpEF) is an increasingly prevalent condition. It occurs more commonly in older patient populations with multiple comorbidities, such as hypertension, diabetes, and obesity. However, managing HFpEF has been challenging due to its complex pathophysiology, and medications effective for heart failure with reduced ejection fraction (HFrEF) have not shown similar efficacy in HFpEF. Sodium-glucose 2 transporter (SGLT2) inhibitors were originally developed for the treatment of type 2 diabetes mellitus, yet several trials and papers have proved their significant role in HFpEF. Through a variety of mechanisms, including natriuresis, diuresis, and anti-inflammatory effects, to name a few, this class of drugs has shown promising results in HFpEF patients. The use of SGLT2 inhibitors in HFpEF has resulted in improvements in several aspects, including biomarkers, imaging, symptomatology, and mortality. Moreover, SGLT2 inhibitors have a favorable safety profile, which is especially significant given the high comorbidity burden in HFpEF patients. This feature is particularly notable given the type of patient being managed. Extensive research is still being undertaken for their use in HFpEF, given the positive results obtained thus far.
