ABSTRACT=<p>The aim of this study is to explore the association between obstructive sleep apnea hypopnea syndrome (OSAHS) complicated with coronary heart disease (CHD) and inflammatory factors, glycolipid metabolism, obesity, and insulin resistance. A total of 400 patients diagnosed with OSAHS who underwent polysomnography (PSG) monitoring in the Sleep Diagnosis and Treatment Center of Beijing Luhe Hospital from March 2015 to September 2018 were selected and divided into the OSAHS group (<italic>n</italic> = 200) and the OSAHS + CHD group (<italic>n</italic> = 200) according to disease condition. The questionnaire survey was conducted, the somatology indexes were measured, and the PSG, insulin, glycolipid metabolism parameters, and serum inflammatory factors were detected. Body weight, body mass index, waist circumference, and Epworth sleepiness scale (ESS) score were all significantly increased in the OSAHS + CHD group compared with those in the OSAHS group (<italic>p</italic> &lt; 0.05). The microarousal index (MAI), apnea hypopnea index (AHI), cumulative percentage of time spent at oxygen saturation below 90% (CT90%), oxygen desaturation index (ODI), lowest oxygen saturation (LSaO<sub>2</sub>), total apnea time (TAT), and mean oxygen saturation (MSaO<sub>2</sub>) had statistically significant differences between the OSAHS + CHD group and the OSAHS group (<italic>p</italic> &lt; 0.05). According to the Spearman correlation analysis of AHI, LSaO<sub>2</sub>, MSaO<sub>2</sub>, CT90%, ODI, and MAI with HOMA-IR in both groups, MAI, AHI, CT90%, and ODI were positively correlated with HOMA-IR (<italic>r</italic> &gt; 0), while LSaO<sub>2</sub> and MSaO<sub>2</sub> were negatively correlated with HOMA-IR (<italic>r</italic> &lt; 0). Compared with the OSAHS group, the OSAHS + CHD group had an obviously increased level of triglyceride (TG) (<italic>p</italic> &lt; 0.05), and obviously increased levels of serum inflammatory factors C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interferon-γ (IFN-γ) (<italic>p</italic> &lt; 0.05). The occurrence of OSAHS complicated with CHD is related to inflammatory factors, glycolipid metabolism, obesity rate, and HOMA-IR.</p>
