Yang KL, Lin PW, Chang CT, et al. OSA Treatment on Cardio- and Cerebrovascular Comorbidities: A Long-term Nationwide Cohort Study. Otolaryngol Head Neck Surg. 2022;167(3):600-606. doi:10.1177/01945998211065656
Objective: To compare the cardio- and cerebrovascular outcomes and survival rates of surgical and nonsurgical interventions for patients with obstructive sleep apnea (OSA) based on a national population-based database.
Study design: Retrospective cohort study.
Setting: Taiwan National Health Insurance Research Database.
Methods: We analyzed all cases of OSA among adults (age >20 years and confirmed with ICD-9-CM) from January 2001 to December 2013. We compared the patients with OSA who received upper airway surgery with age-, sex-, and comorbidity index-matched controls with continuous positive airway pressure (CPAP) treatment. The risk of myocardial infarction (MI) or stroke after treatment of OSA-related surgery versus CPAP was investigated.
Results: During follow-up, 112 and 92 incident cases of MI occurred in the OSA surgery and CPAP treatment groups, respectively (rates of 327 and 298 per 100,000 person-years). Furthermore, 50 and 39 cases were newly diagnosed with stroke in the OSA surgery and CPAP treatment groups (rates of 144 and 125 per 100,000 person-years). Cox proportional hazard regressions showed that the OSA treatment groups (OSA surgery vs CPAP) were not significantly related to MI (hazard ratio, 1.03 [95% CI, 0.781-1.359]; P = .833) and stroke (hazard ratio, 1.12 [95% CI, 0.736-1.706]; P = .596) at follow-up, after adjustment for sex, age at index date, days from diagnosis to treatment, and comorbidities.
Conclusion: Our study demonstrated that there was no difference of cardio- and cerebrovascular results between CPAP and surgery for patients with OSA in a 13-year follow-up.
