Abstract

Background: Sodium-glucose cotransporter 2 (SGLT2) inhibitors improve health status in heart failure (HF) across the left ejection fraction ejection spectrum. However, the effects of SGLT1 and SGLT2 inhibition on health status are unknown. Objectives: These prespecified analyses of the SOLOIST-WHF (Effect of Sotagliflozin on Cardiovascular Events in Patients with Type 2 Diabetes Post Worsening Heart Failure) trial examined the effects of sotagliflozin vs placebo on HF-related health status. Methods: SOLOIST-WHF randomized patients hospitalized or recently discharged after a worsening HF episode to receive sotagliflozin or placebo. The primary endpoint was total number of HF hospitalizations, urgent HF visits, and cardiovascular death. Kansas City Cardiomyopathy Questionnaire-12 (KCCQ-12) score was a prespecified secondary endpoint. This analysis evaluated change in the KCCQ-12 score from baseline to month 4. Results: Of 1,222 patients randomized, 1,113 (91%) had complete KCCQ-12 data at baseline and 4 months. The baseline KCCQ-12 score was low overall (median: 41.7; Q1-Q3: 27.1-58.3) and improved by 4 months in both groups. Sotagliflozin vs placebo reduced the risk of the primary endpoint consistently across KCCQ-12 tertiles (Ptrend = 0.54). Sotagliflozin-treated patients vs those receiving placebo experienced modest improvement in KCCQ-12 at 4 months (adjusted mean change: 4.1 points; 95% CI: 1.3-7.0 points; P = 0.005). KCCQ-12 improvements were consistent across prespecified subgroups, including left ventricular ejection fraction <50% or ≥50%. More patients receiving sotagliflozin vs those receiving placebo had at least small (≥5 points) improvements in KCCQ-12 at 4 months (OR: 1.38; 95% CI: 1.06-1.80; P = 0.017). Conclusions: Sotagliflozin improved symptoms, physical limitations, and quality of life within 4 months after worsening HF, with consistent benefits across baseline demographic and clinical characteristics.
