Abstract
Introduction: The aim of this study was to explore the 5-to-8-year mortality rates of OSA patients diagnosed with overnight PSG and to find out the relation between PSG parameters and all-cause mortality.
Methods: There were total of 762 patients diagnosed as OSA by overnight polysomnography between 2007-2013 and whom 5- and 8-year mortality data can be reached.
Results: In the age adjusted model, being male, AHI, prolongation of desaturation time, low O2 saturation and presence of comorbidity were found to be factors affecting mortality(Table 1).
Age and desaturation time were found to be a statistically significant risk factor effecting both 5 and 8 year mortality in patients with OSA (OR1.1 95%CI 1.07-1.15 p<0.001, OR1.1 95%CI 1.06-1.15 p<0.001for age 5-year and 8 year mortality respectively, OR1.0 95%CI 1.01-1.06 p=0.001, OR1.01 95%CI 1.00-1.01 p<0.001 for desaturation time 5-year and 8 year mortality respectively)(Table 2).
Conclusion: In this study we showed that desaturation time is a significant risk factor effecting both 5 and 8 year mortality in patients with OSA.
