OBJECTIVE: The purpose of this study was to investigate the relationship of obstructive sleep apnea hypopnea syndrome (OSAHS) with coronary artery lesion quantitative score Syntax Score (SX score) and risk factors for coronary heart disease (CHD).

PATIENTS AND METHODS: A total of 115 patients with OSAHS admitted to the Department of Cardiology in our hospital from January 2011 to June 2015 were selected. Philips Respironics Alice 5 Polysomnography was used for sleep monitoring. The patients were divided into mild group (n=32), moderate group (n=36) and severe group (n=47) according to apnea hypopnea index (AHI). Coronary angiography was performed for the patients, and SX score was calculated. Fasting venous blood was extracted from all patients with OSAHS and sent for detection of blood routine, coagulation, liver and kidney function, blood lipid and other indexes, and all patients received color Doppler echocardiography.

RESULTS: The body weight and body mass index (BMI) of patients with OSAHS in severe group were higher than those in the mild group and moderate group (p<0.05). The content of fibrinogen (FIB) of patients in severe group was higher than that in mild group (p<0.01). The levels of total cholesterol (TC) (p<0.05), blood uric acid (p<0.05), and serum creatinine (p<0.01) of patients in the severe group were significantly higher than those in mild group and moderate group, but there were no differences between mild group and moderate group (p>0.05). Echocardiography suggested that the left atrium diameter 1 (LAD) and pulmonary artery pressure (PAP) of patients in severe group were larger than those in the mild group and moderate group (p<0.01), and the right ventricle anteroposterior diameter (RVD) in the mild group was smaller than those in the moderate group (p<0.05) and severe group (p<0.01). The score of patients with OSAHS in the severe group was higher than those in the mild group and moderate group (p<0.01), and SX score was increased with AHI (r=0.416, p<0.01). Logistic regression analysis showed that AHI and SX score could not be used as indicators to judge the prognosis of patients.

CONCLUSIONS: There is a positive correlation between AHI and SX score in patients with OSAHS, indicating that with the aggravation of respiratory sleep disorder, SX score is increased significantly and the severity of coronary artery lesion is increased accordingly.
