ClinConnect Summary

This study will be a double-blind multicenter randomized study (1:1) to evaluate the effect of dapagliflozin 10 mg per day or placebo on short-term functional capacity evaluated through changes in peak oxygen consumption. This trial will include patients with stable symptomatic heart failure with reduced ejection fraction (HFrEF). Efficacy endpoints will be evaluated at 3 time points: 1) baseline (before dapagliflozin/placebo administration), 2) 30 days after randomization, and, 3) 90 days after randomization. An intermediate clinical visit will be performed one week after study initiation....
