The correlation between triglyceride glucose index and brachial-ankle pulse wave velocity in patients with obstructive sleep apnea

Objective: To investigate the correlation between triglyceride-glucose (TyG) index and brachial-ankle pulse wave velocity (baPWV) in patients with obstructive sleep apnea (OSA). Methods: From October 2020 to February 2023, 205 patients who underwent sleep-breathing monitoring at the Jiangbei Campus and the Cardiac Rehabilitation Center of Zhongda Hospital were selected. According to the quartile of TyG index, the patients were divided into Q1, Q2, Q3 and Q4 groups, and according to the sleep apnea hypopnea index (AHI), the patients were divided into no OSA plus mild OSA group and moderate plus severe OSA group. The relationships between baPWV and each index were evaluated. Results: Among the 250 OSA patients, the higher the TyG index, the higher the proportion of male and hypertension, the higher levels of the body mass index (BMI), total cholesterol, triacylgycerol, low-density lipoprotein cholesterol, fasting blood glucose, uric acid, AHI and baPWV (P＜0.05), while the lower values of the age and mean blood
