The effect of obstructive sleep apnea hypopnea syndrome on short-term all-cause death in elderly patients with coronary heart disease

Objective To explore the impact of obstructive sleep apnea hypopnea syndrome(OSAHS)on all-cause death in elderly patients with coronary heart disease(CHD).Methods A total of 504 elderly patients with CHD admitted to the Structural Cardiology Department of the First Affiliated Hospital of Xi’an Jiaotong University from January 2015 to January 2016 were selected.Among them,285 patients with OSAHS were included in the observation group,and the remaining 219 patients were included in the control group.The patients were followed up every 6 months after being discharged from the hospital.The follow-up time ended in June 2018,with all-cause death of the patient as the study endpoint.The clinical data,respiratory function,cardiac function,blood glucose,blood lipids,inflammatory factor levels and causes of death were collected and compared between the two groups of patients,and the multivariate Cox regression model was used to analyze the risk factors of death in elderly patients with CHD.Results The observation group patients’hypoventilation index(AHI),oxygen desaturation index(ODI4),and blood oxygen saturation below 90%of the total monitoring time percentage(SIT90)were higher than those in the control group(t/χ2=12.410,18.729,38.823,P=0.000),body mass index(BMI),high-sensitivity C-reactive protein(hs-CRP)and interleukin 6(IL-6)levels were higher than those of the control group(t=5.001,38.063,6.981,P=0.000).CHD fatality rate,the all-cause mortality rate was higher than that of the control group(χ2=9.334,15.863,P=0.002,0.000),and the cumulative survival rate was lower than that of the control group(P<0.05).hs-CRP,BMI,OSAHS,SIT90 are an independent risk factors for all-cause mortality in elderly patients with CHD(P<0.05).Conclusion OSAHS is an independent risk factor for all-cause death in elderly patients with CHD.It should arouse sufficient attention in clinic and be given corresponding treatment.
