Background
Sodium Glucose Cotransporter-2 inhibitors (SGLT2-i) have been found tohave protective and therapeutic properties in Heart Failure (HF) patients,regardless of ejection fraction.
Methods
A systematic review and meta-analysis of placebo-controlled randomizedcontrolled trials (RCTs) of SGLT2-i in three groups of HF patients, includingthose with mildly reduced, reduced, or preserved ejection fraction. PubMed,SCOPUS, and Web of Science databases were searched for trials published up tothe 20th of November 2022, using keywords. Data were extracted from publishedreports and bias assessment was performed by the Cochrane risk of bias tool. Wecalculated risk/hazard ratios or mean differences (for dichotomous andcontinuous outcomes; respectively, with corresponding 95% confidence intervals(CI).

Results
A total of 30 RCTs were included. Collectively, 33,517 HF patients,irrespective of the Ejection (EF), were included. Initiation of SGLT2-i inpatients with HF significantly reduced the risk of hospitalization for heartfailure (HHF) (RR=0.74, 95% CI: 0.69, 0.79) and cardiovascular death (RR=0.84,95% CI: 0.77, 0.92). SGLT2-i significantly lowered the death rates and firsthospitalization for heart failure (RR=0.78, 95% CI: 0.74, 0.83). Theysignificantly improved Kansas City clinical summary scores (Meandifference=1.67, 95% CI: 0.56, 2.78) and KCCQ-Total symptom score(MD=3.88, 95%CI: 3.28, 4.47). There was a statistically significant decrease in all-causemortality (RR=0.89, 95% CI: 0.83, 0.96). SGLT2-i reduced the rate of seriousadverse events (RR = 0.92, 95% CI: 0.87, 0.96). SGLT2-i showed bothsimilarities and variations across EF groups. On one hand, the magnitude ofreduction of cardiovascular death was to some extent similar across patientswith HFrEF, HFpEF, and Acute HF (15%, 11%, and 11% relative risk reduction,respectively). But on the other hand, the risk of hospitalization varied acrossthese groups, with reductions of 27%, 19%, and 33%, respectively.
Conclusion
SGLT2inhibitors are safe and effective drugs that reduce the risk of cardiovasculardeath and hospitalization and improve the quality of life of heart failure inpatients with heart failure, irrespective of ejection fraction, supportingtheir role as a foundational therapy for heart failure.
