摘要:

目的 分析脂代谢指标、血清γ-谷氨酰转肽酶(γ-GGT)与冠心病(CHD)合并冠状动脉钙化(CAC)的相关性。方法 选取300例CHD患者的临床资料并根据是否存在CAC将其分为CAC组193例、非CAC组107例。比较2组患者的基本资料,高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C)、总胆固醇(TC)、三酰甘油(TG)、载脂蛋白A1(Apo-A1)、载脂蛋白B(Apo-B)以及γ-GGT水平差异,多因素Logistic回归分析CAC的影响因素,并建立列线图预测模型。结果 比较CAC组和非CAC组基本资料,CAC组年龄更高,高血压和糖尿病患者占比更高,LDL-C、TC、Apo-B、γ-GGT水平更高,Apo-A1水平更低(P<0.05)。Logistic多因素回归分析结果显示,高龄、合并糖尿病以及LDL-C、TC、Apo-B、γ-GGT升高是CHD合并CAC的危险因素,Apo-A1升高是CHD合并CAC的保护因素(P<0.05)。构建的列线图模型AUC为0.880(95%CI:0.840~0.919),具有较好的区分能力。结论 CHD合并CAC与患者脂代谢及γ-GGT水平有关,基于影响因素构建的列线图模型可用于临床预警CAC风险。

Abstract:

Objective To analyze the correlation between lipid metabolism indexes, serum gamma-glutamyl transpeptidyase (γ-GGT) and coronary heart disease (CHD) complicated with coronary artery calcification (CAC). Methods A total of 300 CHD patients admitted in this study were divided into the CAC group (n=193) and the non-CAC group (n=107). Clinical data of the two groups were compared, including high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), total cholesterol (TC), triglyceride (TG), Apolipoprotein A1 (Apo-A1), Apo-B (APO-B) and γ-GGT. The influencing factors of CAC were analyzed by multiple Logistic factors. And a nomogram prediction model was established. Results The basic data of the two groups were compared. Patients of the CAC group was older, had higher proportion of patients with hypertension and diabetes, had higher levels of LDL-C, TC, Apo-B and γ-GGT and lower level of Apo-A1 than those of the non-CAC group (P<0.05). The results of Logistic multivariate regression analysis showed that advanced age, combined history of diabetes, elevated LDL-C, TC, Apo-B and γ-GGT were risk factors of CHD complicated with CAC, while elevated Apo-A1 was the protective factor of CHD complicated with CAC (P<0.05). The AUC of the constructed nomogram model was 0.880 (95%CI:0.840-0.919), which showed good distinguishing ability. Conclusion CHD complicated with CAC is related to lipid metabolism and γ-GGT level. The nomogram model constructed based on influencing factors can be used for clinical early warning of CAC risk.
