Objective  To evaluate prognostic impact of treatment with Continuous Positive Airway Pressure (CPAP) or upper airway surgery on the patients with obstructive sleep apnea (OSA) and coronary heart disease (CHD).
Methods  Database search in The Cochrane Library, PubMed, OVID and CBM (from establishment dates to October 2009) were conducted. Cohort studies and randomized controlled trials of OSA with CPAP or upper airway surgery in CHD patients were identified. We assessed the quality of the included trials and extracted the relevant data. Statistical analysis was performed using RevMan 4.3.2 software.
Results  A total of 4 cohort studies involving 945 participants were included. The results of meta-analysis were as follows: a) there were no significant differences in the rate of late lumen loss and 10-year mortality between CHD patients with OSA treated by CPAP and those without OSA (RR=1.84, 95%CI 0.73 to 4.68, P=0.20; RR=0.80, 95%CI 0.24 to 2.64, P=0.71). b) CPAP or uvulopalatopharyngoplasty used in the treatment of OSA on CHD patients after PCI had a significant decrease in the rate of 5-year cardiac death when compared with those untreated OSA patients (RR=0.34, 95%CI 0.14 to 0.82, P=0.02). But there were no differences in the rate of 5-year all-cause mortality, major adverse cardiac events (MACE) between the two groups respectively (RR=0.66, 95%CI 0.39 to 1.10, P=0.11; RR=0.97, 95%CI 0.81 to 1.15, P=0.69). c) CPAP or upper airway surgery in treating OSA significantly reduced the risk of MACE occurrence during the 86.5±39 months follow-up period (RR=0.22, 95%CI 0.07 to 0.72, P=0.01).
Conclusion  Current evidence indicates that treating OSA with CPAP or upper airway surgery in CHD patients might be associated with a decrease in the risk of cardiac death. But more studies are necessary to evaluate prognostic impact of treatment with CPAP or upper airway surgery on the patients with OSA and CHD. However, due to the limited quantity and quality of the included studies, more high-quality studies are need.
