Long Term Cardiovascular Outcomes Between Sleep Surgery and Continuous Positive Airway Pressure

Objectives: Individuals with obstructive sleep apnea (OSA) suffer from a multitude of concurrent morbidities including cardiovascular disease (CVD). Limited data exists comparing long term cardiovascular disease (CVD) clinical outcomes for patients treated with surgical intervention versus continuous positive airway pressure (CPAP). The purpose of this study was to compare CVD outcomes at multiple time points comparing those treated with sleep surgery versus CPAP alone.Methods: A research database was used to assess outcomes: death, myocardial infarction, atrial fibrillation, heart failure, essential hypertension, and pulmonary hypertension at 5, 8, and 20 years for patients with OSA treated with surgical interventions (upper airway stimulation [UAS], uvulopalatopharyngoplasty [UPPP], and tonsillectomy) or CPAP alone. Subjects were identified using ICD and CPT codes and analyses were conducted with and without propensity score matching for age, sex, race, BMI, myocardial infarction (MI), essential hypertension, pulmonary hypertension, atrial fibrillation, and heart failure.Results: All surgical interventions demonstrated benefit over CPAP alone at most time points for most surgical interventions. At 8 years, for all sleep surgeries (UAS or UPPP or tonsillectomy) (n = 6627) versus treatment with CPAP alone (n = 6627), matched subjects demonstrated decreased risk (odds ratios) and superior survival (hazard ratios and log ranks tests) for death (OR = 0.49 [0.39, 0.62] P <= .0001, HR = 0.29 [0.23, 0.37], chi 2 = 109.58 P <= .0001), myocardial infarction (OR = 0.67 [0.54, 0.84] P = .0005*, HR = 0.48 [0.38, 0.60], chi 2 = 42.40 P <= .0001), atrial fibrillation (OR = 0.70 [0.59, 0.83] P <= .0001, HR = 0.54 [0.45, 0.64], chi 2 = 51.53 P <= .0001), heart failure (OR = 0.55 [0.47, 0.64] P <= .0001, HR = 0.41 [0.35, 0.47], chi 2 = 137.416 P <= .0001), essential hypertension (OR = 0.88 [0.82, 0.94] P = .0002, HR = 0.78 [0.74, 0.82], chi 2 = 76.38 P <= .0001), and pulmonary hypertension (OR = 0.51 [0.40, 0.65] P <= .0001, HR = 0.38 [0.29, 0.48], chi 2 = 60.67 P <= .0001) where P <= .00037 indicated statistical significance*.Conclusion: This investigation suggests surgical management of obstructive sleep apnea may contribute to the mitigation of long-term clinical CVD morbidity.
