Abstract:
Objective:To explore the predictive value of triglyceride-glucose (TyG) index and residual cholesterol (RC) for intracranial artery stenosis (ICAS) in a physical examination population with H-type hypertension.Methods:It was a cross-sectional study. A total of 3 452 individuals with H-type hypertension who underwent physical examinations at the Health Management Center of Fuwai Central China Cardiovascular Hospital from September 2021 to March 2025 were continuously selected as the research subjects. Magnetic resonance angiography was used to assess intracranial artery stenosis, and the subjects were divided into a non-ICAS group (2 018 cases) and ICAS group (1 344 cases). The clinical indicators of the two groups were collected, including past medical history, height, weight, waist-hip ratio, smoking history, drinking history, blood pressure, total cholesterol, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, fasting plasma glucose and homocysteine. The logistic regression analysis was used to analyze the related factors of ICAS in the physical examination population with H-type hypertension. The predictive value of TyG index and RC for the occurrence of ICAS in the physical examination population with H-type hypertension was evaluated by using the receiver operating characteristic (ROC) curve.Results:Among the 3 452 physical examination individuals with H-type hypertension included in the analysis, there were 2 285 males (66.2%) and 1 167 females (33.8%), with an age of (41.36±8.99) years. The levels of smoking history, drinking history, overweight/obesity, increased waist-to-hip ratio, age, triglycerides, homocysteine, TyG index and RC in the ICAS group were all higher than those in the non-ICAS group [66.6% vs 36.8%, 70.2% vs 38.0%, 70.0% vs 48.5%, 76.2% vs 40.6%, (45.53±10.32) vs (39.59±9.38) years, 1.79 (1.35, 2.97) vs 1.42 (0.91, 2.53) mmol/L, 22.15 (19.76, 24.89) vs 18.52 (16.26, 20.66) μmol/L, 8.89 (8.62, 9.75) vs 7.85 (7.24, 8.47), 0.84 (0.50, 1.60) vs 0.66 (0.42, 1.04) mmol/L], the level of high-density lipoprotein cholesterol was lower than that in the non-ICAS group [1.03 (0.91, 1.24) vs 1.26 (0.99, 1.52) mmol/L](all P<0.05). Spearman correlation analysis showed that ICAS was positively correlated with body mass index, waist-hip ratio, total cholesterol, TyG index and RC ( r=0.167, 0.219, 0.224, 2.536, 0.379), and it was negatively correlated with high-density lipoprotein cholesterol ( r=-0.314) (all P<0.05). The logistic regression analysis showed that TyG index ( OR=10.293, 95% CI: 5.128-21.614) and RC ( OR=1.045, 95% CI: 0.139-1.328) were both positively correlated with ICAS (both P<0.05). The ROC curve analysis showed that the area under the ROC curve of TyG index combined with RC for predicting ICAS in the physical examination population with H-type hypertension was 0.750, with a sensitivity of 80.8% and a specificity of 73.2%, which was superior to predictive power of TyG index or RC alone (both P<0.05). Conclusion:Both TyG index and RC have good predictive value for ICAS in the physical examination population with H-type hypertension, and combination of both has a higher predictive performance.
