Abstract:

Objective To explore the predictive value of metabolic score for insulin resistance (METS-IR) in patients with essential hypertension combined with aortic arch calcification (AAC). Methods A total of 170 patients with essential hypertension admitted in the Beijing Renhe Hospital from February 2022 to February 2025 were retrospectively selected. According to the Symeonidis method, the aortic arch calcification score (AoACS) was measured and divided patients into the AoACS =0 group (n=60), AoACS =1 group (n=46), AoACS=2 group (n=33) and AoACS=3 group (n=31). Smoking history, drinking history, diabetes history, gender, age, blood pressure, body mass index (BMI), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and fasting plasma glucose (FPG) were compared. The correlation and predictive value of each index with AAC in patients with essential hypertension were analyzed. Results There were no significant differences in the proportions of drinking history, gender and TG level among the four groups (P>0.05). There were significant differences in the proportion of smoking history, the proportion of diabetes history, age, diastolic blood pressure, systolic blood pressure, LDL-C, HDL-C, FPG, BMI and METS-IR among the four groups (P<0.05). METS-IR, smoking history, diabetes history, age, LDL-C, HDL-C, FPG, BMI, systolic blood pressure and diastolic blood pressure were used as independent variables for ordinal logistic regression analysis. The results showed that HDL-C was a protective factor for AAC, and the other indicators were risk factors for AAC (P<0.05). The receiver operating characteristic (ROC) curve showed that the area under the curve (AUC) of METS-IR in predicting primary hypertension complicated with AAC was 0.92, with a specificity of 96.67%, and a sensitivity of 80.00%(P<0.001). Conclusion METS-IR, age, smoking, LDL-C, diabetes history, FPG, BMI, and blood pressure (both systolic and diastolic) are significant risk factors for AAC in patients with essential hypertension, while HDL-C serves as a protective factor. METS-IR demonstrated superior predictive value for the presence and severity of AAC.
