Insights
Sodium-glucose cotransporter 2 inhibitors (SGLT2i) significantly reduce the risk of both ischaemic and haemorrhagic strokes in patients with type 2 diabetes and chronic kidney disease. This finding supports SGLT2i as a potential clinical option for stroke prevention in this high-risk population.
Area of Science:
- Cardiovascular Medicine
- Nephrology
- Endocrinology
Background:
- Type 2 diabetes and chronic kidney disease are significant risk factors for both ischaemic and haemorrhagic strokes.
- The role of sodium-glucose cotransporter 2 inhibitors (SGLT2i) in mitigating stroke risk in patients with co-existing type 2 diabetes and chronic kidney disease requires further elucidation.
Purpose of the Study:
- To investigate the efficacy of SGLT2 inhibitors in preventing incident ischaemic and haemorrhagic strokes among patients with type 2 diabetes and chronic kidney disease.
Main Methods:
- A retrospective cohort study utilizing propensity score matching (1:1) and Cox regression analysis to compare stroke incidence between SGLT2i users and non-users.
- Kaplan-Meier analysis assessed long-term stroke risk.
- Sensitivity analysis with 1:2 sex and age matching further validated the findings.
Main Results:
- Analysis included 107,819 SGLT2i users and 107,819 non-users after propensity score matching.
- SGLT2i therapy demonstrated a significant reduction in the incidence of ischaemic strokes (HR 0.86, 95% CI 0.81-0.90) and haemorrhagic strokes (HR 0.80, 95% CI 0.74-0.87).
- Sensitivity analyses confirmed the significant protective effect of SGLT2i against both stroke types.
Conclusions:
- SGLT2 inhibitors effectively reduce the risk of incident ischaemic and haemorrhagic strokes in patients concurrently diagnosed with type 2 diabetes and chronic kidney disease.
- The demonstrated protective effects position SGLT2 inhibitors as a viable clinical strategy for stroke prevention in this vulnerable patient group.
Background:
Type 2 diabetes (T2D) and chronic kidney disease (CKD) increase the risk of ischaemic and haemorrhagic strokes. However, the effect of sodium-glucose cotransporter 2 inhibitors (SGLT2i) on reducing the risk of ischaemic and haemorrhagic strokes in patients with T2D and CKD remains unclear. Thus, this study was conducted to explore the role of SGLT2i in the prevention of ischaemic and haemorrhagic strokes.
Methods:
In this retrospective cohort study, Cox regression analysis was employed to examine the hazard ratio (HR) between users and nonusers of SGLT2i on incident ischaemic and haemorrhagic strokes following 1:1 propensity score matching. The Kaplan-Meier method was used to determine the risk of study outcome over time between users and nonusers of SGLT2i. Finally, a sensitivity analysis of the HR was performed between users and nonusers of SGLT2i on incident ischaemic and haemorrhagic strokes after 1:2 sex and age matching.
Results:
After 1:1 propensity score matching of patients by age, sex, T2D duration, and comorbidities, 107,819 users of SGLT2i and 107,819 nonusers were enrolled for analysis. SGLT2i therapy was associated with significantly reduced incidence of ischaemic and haemorrhagic strokes (HR 0.86, [95% CI, 0.81-0.90]; HR 0.80, [95% CI, 0.74-0.87]). Furthermore, the HR was even more significant in the sensitivity test for incident ischaemic and haemorrhagic strokes.
Conclusion:
SGLT2i reduced the risk of incident ischaemic and haemorrhagic strokes among patients with T2D and CKD. The protective profile of the SGLT2i against incident ischaemic and haemorrhagic strokes makes it a clinical option for those with T2D with CKD.
