Insights
Sodium-glucose cotransporter-2 inhibitors (SGLT2i) significantly reduced hospitalization, mortality, and pulmonary edema in heart failure and end-stage kidney disease patients. This suggests SGLT2i may be a valuable treatment for this high-risk population.
Area of Science:
- Nephrology
- Cardiology
- Pharmacology
Background:
- Patients with heart failure (HF) and end-stage kidney disease (ESKD) have limited therapeutic options and high mortality rates.
- Sodium-glucose cotransporter-2 inhibitors (SGLT2i) show cardiovascular and renal benefits, but their impact in HF and ESKD is understudied due to trial exclusions.
Purpose of the Study:
- To evaluate the effectiveness of SGLT2i in reducing one-year clinical outcomes in patients with HF and ESKD.
- Key outcomes included all-cause hospitalization, all-cause mortality, and acute pulmonary edema.
Main Methods:
- A retrospective cohort study utilized the TriNetX network, analyzing patients with HF and ESKD from 2016-2025.
- Propensity score matching (PSM) balanced baseline characteristics between SGLT2i users and non-users.
- Cox proportional hazard models assessed the primary composite outcome and secondary outcomes, with sensitivity analyses performed.
Main Results:
- The study analyzed 10,032 patients post-PSM.
- SGLT2i use was linked to a significantly lower risk of the primary composite outcome (all-cause hospitalization, mortality, acute pulmonary edema) at one year (HR 0.80, 95% CI 0.76-0.84).
- Consistent benefits were observed across various HF phenotypes, comorbidities, and SGLT2i types.
Conclusions:
- SGLT2i are significantly associated with reduced one-year hospitalization, mortality, and acute pulmonary edema in patients with HF and ESKD.
- These findings suggest a potential therapeutic role for SGLT2i in this vulnerable population.
- Further clinical trials are warranted to confirm the efficacy and safety of SGLT2i in HF and ESKD patients.
Background:
Patients with heart failure (HF) and end-stage kidney disease (ESKD) face a high burden of mortality and hospitalization, yet effective therapeutic options remain limited. While sodium-glucose cotransporter-2 inhibitors (SGLT2i) have demonstrated cardiovascular and renal benefits across various chronic kidney disease (CKD) stages, their effects in patients with HF and ESKD remain uncertain due to their exclusion from major clinical trials.
Objectives:
This study aimed to evaluate the effectiveness of SGLT2i in reducing one-year clinical outcomes, including all-cause hospitalization, all-cause mortality, and acute pulmonary edema in patients with HF and ESKD.
Methods:
A retrospective cohort study was conducted using the TriNetX network. Patients with HF and ESKD diagnosed between 2016 and 2025 were identified and categorized into SGLT2i users and non-users. The primary outcome was a composite of all-cause hospitalization, all-cause mortality, and acute pulmonary edema at 1 year. Secondary outcomes included each component of the primary composite. Propensity score matching (PSM) was applied to balance baseline characteristics. Cox proportional hazard models estimated hazard ratios (HRs) with 95% confidence intervals (CIs) for primary and secondary outcomes. Sensitivity analyses, including negative control and landmark analyses, were performed to validate findings.
Results:
After PSM, 10,032 patients were analyzed. SGLT2i use was associated with a significantly lower risk of the primary composite outcome (HR 0.80, 95% CI 0.76-0.84, p < 0.001). Subgroup analyses demonstrated consistent benefits across different HF phenotypes, comorbidities, and different types of SGLT2i.
Conclusions:
SGLT2i are significantly associated with reduced 1 year all-cause hospitalization, mortality, and acute pulmonary edema in HF and ESKD patients. These findings highlight the potential therapeutic role of SGLT2i in this high-risk population, warranting further clinical trials to confirm their efficacy and safety.
