摘要: 背景 血脂代谢异常是急性心肌梗死(AMI)发生、发展的重要危险因素,但在一些血脂正常的人群中,仍有AMI的发生。残粒脂蛋白胆固醇(RLP-C)、血浆致动脉粥样硬化指数(AIP)作为非常规血脂指标,与AMI之间的研究尚少,同时两者对青年初发AMI的预测价值有待研究。 目的 探讨RLP-C、AIP对青年初发AMI的预测价值。 方法 选取江苏省苏北人民医院心血管内科于2014年11月至2021年11月拟诊冠心病入院的患者1 201例为研究对象,根据是否为AMI将其分为AMI组(627例)和非AMI组(574例)。收集两组患者的一般资料以及三酰甘油(TG)、总胆固醇(TC)、高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C)等指标,根据公式计算出RLP-C和AIP,并进行比较。采用Logistic回归分析探讨青年初发AMI的影响因素;采用受试者工作特征曲线(ROC曲线)评估RLP-C、AIP对青年初发AMI的预测价值。 结果 两组患者男性、吸烟史、高血压史比例,TG、TC、HDL-C、LDL-C、RLP-C、AIP水平比较,差异有统计学意义(P<0.05)。多因素Logisitic回归分析结果显示,有吸烟史〔OR=2.541,95%CI(1.824,3.538)〕、TC≥5.17 mmol/L〔OR=2.787,95%CI(1.405,5.531)〕、RLP-C≥0.6 mmol/L〔OR=3.786,95%CI(2.648,5.413)〕、AIP≥0.2〔OR=3.427,95%CI(2.106,5.576)〕为青年初发AMI的独立危险因素(P<0.05);HDL-C≥1.19 mmol/L〔OR=0.049,95%CI(0.025,0.093)〕为青年初发AMI的独立保护因素(P<0.05)。RLP-C预测青年初发AMI的ROC曲线下面积(AUC)为0.851〔95%CI(0.830,0.873)〕,最佳截断值为0.535 mmol/L,灵敏度和特异度分别为0.848和0.699;AIP预测青年初发AMI的AUC为0.813〔95%CI(0.789,0.837)〕,最佳截断值为0.122,灵敏度和特异度分别为0.852和0.660。 结论 研究结果提示有吸烟史、TC≥5.17 mmol/L、RLP-C≥0.6 mmol/L、AIP≥0.2可能为青年初发AMI的独立危险因素;HDL-C≥1.19 mmol/L可能为青年初发AMI的独立保护因素。RLP-C、AIP对青年初发AMI具有一定的临床预测价值。

Abstract:

Background

Acute myocardial infarction (AMI) can be found in some patients with normal serum lipids although abnormal lipid metabolism is a major risk of AMI. The association of AMI with two unconventional lipid parameters, namely residual lipoprotein-cholesterol (RLP-C) and atherogenic index of plasma (AIP), has been studied rarely, and the predictive value of RLP-C and AIP for first-time AMI in young adults still needs to be explored.

Objective

To assess the value of RLP-C and AIP in predicting first-time AMI in young adults.

Methods

A total of 1 201 inpatients aged 18-45 years old with an initial diagnosis of coronary heart disease (CHD) were selected from Northern Jiangsu People's Hospital from November 2014 to November 2021, including 627 with first-time AMI and 574 without. General demographics, triglyceride (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) and other indicators were collected, and RPL-C and AIP were calculated according to the formula for statistical analysis. Logistic regression analysis was used to explore the influencing factors of first-time AMI. Receiver operating characteristic (ROC) analysis was used to evaluate the predictive value of RLP-C and AIP for first-time AMI.

Results

CHD patients with and without first-time AMI had significant differences in male ratio, smoking history, hypertension history, and average levels of TG, TC, HDL-C, LDL-C, RLP-C and AIP (P<0.05). Multivariate Logistic regression analysis showed that smoking history〔OR=2.541, 95%CI (1.824, 3.538) 〕, TC≥5.17 mmol/L〔OR=2.787, 95%CI (1.405, 5.531) 〕, RLP-C≥0.6 mmol/L〔OR=3.786, 95%CI (2.648, 5.413) 〕 and AIP≥0.2〔OR=3.427, 95%CI (2.106, 5.576) 〕independently increased the risk for first-time AMI (P<0.05), while HDL-C≥1.19 mmol/L〔OR=0.049, 95%CI (0.025, 0.093) 〕independently decreased the risk of first-time AMI (P<0.05). In ROC analysis, the performance of RLP-C and AIP predicting first-time AMI was as follows: RLP-C had an AUC of 0.851〔95%CI (0.830, 0.873) 〕, with 0.535 mmol/L as the optimal cut-off value, 0.848 sensitivity and 0.699 specificity; AIP had an AUC of 0.813〔95%CI (0.789, 0.837) 〕, with 0.122 as the optimal cut-off value, 0.852 sensitivity and 0.660 specificity.

Conclusion

The risk of first-time AMI in young adults may be increased by smoking history, TC≥5.17 mmol/L, RLP-C≥0.6 mmol/L and AIP≥0.2, and decreased by HDL-C≥1.19 mmol/L. RLP-C and AIP may partially predict first-time AMI.
