Summary: This study aimed to explore the effect of bisphosphonate treatment on stroke using a large population cohort study. We found that the patients who received bisphosphonate therapy were less likely to suffer a stroke than comparison patients (hazard ratio (HR)00.79; 95% confidence interval (CI)00.66-0.99; p00.005) during a 2-year follow-up period. Introduction: Animal models have suggested that bisphosphonates have a beneficial effect on the cardiovascular system. However, data on this topic in human subjects are still lacking. This study aimed to explore the protective effect of bisphosphonate treatment on stroke using a large population cohort study. Methods: We identified 2,148 patients who received bisphosphonate therapy for osteoporotic fractures. We randomly extracted 6,444 subjects with vertebral or hip fractures as a comparison group matched with the study group on age, sex, and year of index date. Each patient was individually tracked for 2 years to identify those who suffered a stroke. Stratified Cox proportional hazards regressions were performed to assess the effect of bisphosphonate treatment on the risk of stroke. Results: We found that 184 (8.6%) patients who received bisphosphonate therapy and 696 (10.8%) comparison patients suffered a stroke during the follow-up period. After adjusting for demographic variables and medical comorbidities, stratified Cox proportional hazards regressions stratified by propensity score revealed that patients who received bisphosphonate therapy were less likely to suffer a stroke than comparison patients (HR00.79; 95% CI0 0.66-0.99). The adjusted HR for subarachnoid/intracerebral hemorrhage for patients who received bisphosphonate therapy was only 0.53 times (95% CI00.33-0.92) that of comparison patients, and the hazard of having an ischemic stroke during the 2-year follow-up period was 0.81 times that of comparison patients (95% CI00.65-0.96). Conclusion: Patients who received bisphosphonate therapy were associated with a lower risk of stroke during a 2-year follow-up period.
