Purpose

This study will be the first trial to evaluate the safety and efficacy of dapagliflozin treatment in preventing readmissions/ER visits/urgent clinic visits, and death in patients with and without T2D after admission for heart failure. Treatment with SGLT2-i has been shown to reduce both heart failure hospitalizations and mortality in patients with established heart disease. However, the time of initiation of SGLT2-i therapy has not been evaluated in patients with HF. In addition, the impact of treatment on HF symptoms quality of life, resource utilization, and cost-effectiveness of dapagliflozin versus placebo will be evaluated. The results of this study have great potential to impact and facilitate care and to change current clinical guidelines in the management of patients with heart failure.

Detailed Description

The prevalence of both heart failure and type 2 diabetes (T2D) or prediabetes are reaching epidemic proportions globally and in the United States. More than 40% of patients with established heart failure (HF) have diabetes. This study will be the first trial to evaluate the safety and efficacy of dapagliflozin treatment in preventing hospital re-admissions/ER visits/urgent clinic visits, and death in patients with and without T2D after admission for heart failure. Treatment with SGLT2-i has been shown to reduce both heart failure hospitalizations and mortality in patients with established heart disease. However, the time of initiation of SGLT2-i therapy has not been evaluated in patients with HF. In addition, the impact of treatment on HF symptoms quality of life, resource utilization, and cost-effectiveness of dapagliflozin versus placebo will be evaluated. The results of this study have great potential to impact and facilitate care and to change current clinical guidelines in the management of patients with heart failure. Patients with and without diabetes who have acute decompensated heart failure (ADHF) will be randomized to receive either dapagliflozin (10 mg once daily) or placebo at hospital discharge for 26 weeks.
