Abstract

Objective To analyse the association between triglyceride glucose (TyG) index and the number of coronary artery lesions in patients with stable coronary artery disease. Methods It was a cross‑sectional study. Patients with stable coronary artery disease who were admitted to Zhongshan Hospital, Fudan University from 1st January 2019 to 30th April 2020 for percutaneous coronary intervention (PCI) were selected. We collected general clinical information and laboratory results from the enrolled patients, then calculated the TyG index. We evaluated coronary artery lesions by coronary angiography and analysed the factors associated with the number of coronary artery lesion branches by the logistic regression model. Results A total of 832 patients were included in this study, 641 (77.0%) were male, the age was (64.6±11.5) years. The mean TyG index was 8.78. Patients with the TyG index≥8.78 were included in the high TyG index group (411 patients), and those with the TyG index<8.78 were included in the low TyG index group (421 patients). Compared with the low TyG index group, the high TyG index group had the higher body mass index and diastolic blood pressure, more smokers and diabetes mellitus, younger age of onset of coronary heart disease (all P<0.05), and a lower proportion of patients using statins (P= 0.027). Compared with the low TyG index group, the high TyG index group had the higher levels of erythrocyte count, hemoglobin, white blood cell count, albumin, urea nitrogen, uric acid, fasting blood glucose, HbA1c, triglyceride, low‑density lipoprotein cholesterol, non‑high‑density lipoprotein cholesterol, apolipoprotein B, apolipoprotein E, and C ‑ reactive protein (all P<0.05). However, the levels of high density lipoprotein, apolipoprotein A1 and apolipoprotein A were lower in the high TyG index group than those in the low TyG index group (all P<0.05). The number of coronary artery lesions in patients in the high TyG index group was 2.35±0.91, more than the low TyG index group 2.10±0.95 (P<0.001). After adjusting for the other factors, multivariate logistic regression analysis showed that male, smoking history (smoking cessation or smoking), TyG index and troponin T levels were independently positively associated with the number of coronary artery lesions (all OR>1, P< 0.05), while ApoA1 was independently negatively associated with the number of coronary artery lesions (OR=0.140, P=0.007). Conclusions TyG index is positively associated with the number of coronary artery lesions in patients with stable coronary artery disease.
