血浆致动脉硬化指数评价急性ST段抬高型心肌梗死的临床价值

Clinical value of atherogenic index of plasma in elevating acute ST-segment elevation myocardial infarction

目的:探讨血浆致动脉硬化指数(atherogenic index of plasma, AIP)预测急性ST段抬高型心肌梗死的临床价值。方法:选取我院2018年12月—2022年3月期间因胸痛、胸闷等疑诊急性心肌梗死(acute myocardial infarction, AMI)住院且行冠状动脉造影(coronary angiography, CAG)检查的患者80例为AMI组,同期因胸闷、胸痛住院,行CAG检查为正常者48例为对照组,比较两组患者的一般资料和相关实验室检查结果并计算AIP。以是否AMI为因变量,控制混杂因素吸烟史、入院时收缩压、入院时舒张压、空腹血糖、白细胞计数(WBC)、尿酸,分别以AIP为自变量进行二元logistic回归分析。结果:两组患者在吸烟比例、入院时收缩压、入院时舒张压、WBC、甘油三酯(triglyceride, TG)、高密度脂蛋白(high density lipoprotein, HDL)、低密度脂蛋白(low density lipoprotein, LDL)、空腹血糖、尿酸、AIP等方面进行比较,均差异有统计学意义(均P<0.05)。二元logistic回归分析显示,AIP是AMI的独立预测指标;AIP预测AMI的AUC为0.81,差异有统计学意义(95%CI:0.732~0.887,P<0.001)。最佳截断值为-0.061,并根据最大约登指数确定灵敏度为82.5%,特异度为66.7%。结论:AIP是AMI的独立危险因素,对预测AMI的发生和临床防治均有一定的指导价值。

Objective:To investigate the clinical value of atherogenic index of plasma(AIP)in predicting acute ST-segment elevation myocardial infarction.Methods:Eighty patients who were hospitalized for suspected acute myocardial infarction with chest pain and underwent coronary angiography(CAG)during the period from December 2018 to March 2022 were collected as the experimental group,and 48 patients who were hospitalized for chest tightness and chest and underwent CAG examination as normal during the same period were selected as the control group.The general data and relevant laboratory findings of the patients were compared and the AIP was calculate.Take whether acute myocardial infarction or not as the dependent variable,control the confounding factors,including smoking history,systolic and diastolic blood pressure at admission,fasting blood glucose,white blood cell(WBC),uric acid,and carry out binary logistic regression analysis according to the AIP as the independent variable.Results:There were statistically significant differences in the proportion of patients smoking,systolic blood pressure on admission,diastolic blood pressure on admission,WBC,triglyceride(TG),high density lipoprotein(HDL),low density lipoprotein(LDL),fasting glucose,uric acid and AIP between the two groups,the differences were statistically significant(all P<0.05).Binary logistic regression analysis showed that AIP was an independent predictor of acute myocardial infarction;The area under the curve of acute myocardial infarction predicted by AIP was 0.81(95%CI:0.732-0.887,P<0.001).The best cutoff value was-0.061.The sensitivity was 82.5%and the specificity was 66.7% based on the maximum Jordan index.Conclusion:AIP is an independent risk factor for acute myocardial infarction and is a useful guide for predicting the occurrence of acute myocardial infarction and clinical prevention management.
