Early use of SGLT2 inhibitors in hospitalized patients with acute heart failure was associated with a reduction in the incidence of composite events in the short term (relative risk (RR) = 0.64, 95% confidence interval (CI) (0.56, 0.74)), all-cause mortality (RR = 0.72, 95% CI (0.60, 0.86)), and heart failure rehospitalization rates (RR= 0.77, 95% CI (0.63, 0.87)); however, the early use of SGLT2i did not improve the incidence of cardiogenic death (RR = 0.74, 95% CI (0.51, 1.08)). This evidence concerns the gene SLC5A2 and heart failure.
