Why the study?

Recent RCTs showed prognostic cardiovascular benefits of SGLT2 inhibitors in diabetes, motivating an evaluation of their role in heart failure regardless of baseline diabetes status.

Do SGLT2 inhibitors reduce mortality and cardiovascular events in patients with heart failure regardless of baseline diabetes status?

Comparison

Design

Systematic review and meta-analysis

Key result

SGLT2 inhibitors reduced the risk of all-cause mortality (HR 0.83; 95% CI 0.75-0.91) and hospitalization for HF or CV death (HR 0.72; 95% CI 0.66-0.78) in patients with heart failure.

SGLT2 inhibitors significantly reduce all-cause mortality, cardiovascular death, and heart failure hospitalizations in patients with heart failure, regardless of their baseline diabetes status.

Cite This Study

Tsampasian et al. (2021) conducted a meta-analysis in Heart failure (n=13,275). SGLT2 inhibitors was evaluated on All-cause mortality (HR 0.83, 95% CI 0.75-0.91). SGLT2 inhibitors reduced the risk of all-cause mortality (HR 0.83; 95% CI 0.75-0.91) and hospitalization for HF or CV death (HR 0.72; 95% CI 0.66-0.78) in patients with heart failure.
