SLC5A2 and heart failure: Compared to placebo, SGLT2 inhibitors significantly reduced heart failure hospitalization [risk ratio (RR) 0.70, 95% confidence interval (CI) 0.59–0.83] and kidney-specific composite outcome (RR 0.55, 95% CI 0.40–0.75) and increased Kansas City Cardiomyopathy Questionnaire total score by 1.15 (95% CI 1.05–1.25) in patients without T2DM with heart failure (HF) or chronic kidney disease (CKD), whereas gliflozins did not significantly affect cardiovascular death, all-cause mortality, volume depletion, fracture, and amputation in this vulnerable population.
