Brief Summary

The aim of prospective, open label, single center, randomized controlled trial is to investigate the efficacy of enavogliflozin on exercise performance, diastolic dysfunction, and quality of life in patients with heart failure with preserved ejection fraction (HFpEF).

Detailed Description

HFpEF is a clinically heterogenous syndrome and has unique characteristics that differ from the other entities of heart failure. Cardiovascular and non-cardiovascular comorbidities are known to contribute to the pathogenesis of HFpEF, and consequently, the importance of HFpEF is increasingly emphasized as the population ages. In fact, HFpEF occurs in approximately 5% of the general population aged over 60 years and account for half of hospitalization for heart failure. Notwithstanding, no medication has been found to be effective for HFpEF. Only recently, Sodium glucose cotransporter 2 (SGLT2) inhibitors was proven effective in patients with HFpEF in two landmark trials, EMPEROR-Preserved and DELIVER trials. In both trials, SGLT2 inhibitor was consistently associated with reduced risk of composite outcome of cardiovascular death and hospitalization for heart failure. In this regard, 2023 focused update of the 2021 European Society of Cardiology (ESC) guidelines for heart failure recommends SGLT2 inhibitor as class 1A recommendation in patients with HFpEF.

Despite the solid evidence about the clinical benefit of SGLT2 inhibitor in patients with HFpEF, little is known about the mechanisms responsible for the beneficial cardiac effects of SGLT2 inhibitor. Patients with HFpEF are known to have impaired exercise and functional capacity, which lead to declined quality of life and debilitating symptoms. Along with unclear mechanisms responsible for the beneficial cardiac effect of SGLT2 inhibitor, the impacts of SGLT2 inhibitor on exercise and functional capacity in patients with HFpEF have also not been clearly evaluated. Therefore, this trial aim to evaluate the impact of SGLT2 inhibitor on exercise performance, diastolic function, and quality of life in patients with HFpEF using newly developed SGLT2 inhibitor, Enavogliflozin.
