摘要: 背景 代谢功能障碍相关脂肪性肝病(MASLD)是一种与代谢紊乱密切相关的脂肪肝疾病,胰岛素抵抗(IR)在其病理生理机制中起关键作用,并被认为是心血管代谢风险的重要组成部分。 目的 探讨不同IR替代指标与MASLD合并冠心病(CHD)患者经皮冠状动脉介入治疗(PCI)术后主要不良心血管事件(MACEs)的关联,并筛选适用于该人群的简便预测指标。 方法 回顾性纳入2019-01-01—2023-10-31在苏北人民医院确诊MASLD合并CHD并行PCI的958例患者为研究对象,收集患者基线资料,超声心动图评估患者心脏功能,超声检查患者肝脏情况,依据患者实验室检查结果计算IR替代指标。对患者进行随访,收集患者术后MACEs的发生情况。采用Cox比例风险回归模型探讨患者预后的影响因素,绘制受试者工作特征(ROC)曲线评估IR替代指标对MACEs的预测效能。绘制Kaplan-Meier生存曲线比较患者随访过程中累积生存率的差异,组间比较采用Log-rank检验。采用非线性趋势限制立方样条(RCS)曲线探讨IR替代指标与患者术后预后的关系。 结果 根据随访结果,将患者分为非MACEs组(n=768)和MACEs组(n=190)。非MACEs组与MACEs组白细胞计数、中性粒细胞计数、单核细胞计数、空腹血糖(FPG)、甘油三酯(TG)、高密度脂蛋白胆固醇(HDL-C)、载脂蛋白A、载脂蛋白B、白蛋白、天冬氨酸氨基转移酶、甘油三酯高密度脂蛋白胆固醇-葡萄糖体指数(TyHGB)、甘油三酯-葡萄糖指数(TyG)、TG/HDL-C、胰岛素抵抗代谢评分(METS-IR)比较,差异有统计学意义(P<0.05)。Cox比例风险回归模型分析结果显示,TyG(HR=1.820,95%CI=1.223~2.707)、METS-IR(HR=7.309,95%CI=3.770~14.170)升高是患者术后发生MACEs的危险因素(P<0.05);分别将研究对象按TyG、TG/HDL-C、TyHGB、METS-IR四分位数分组(Q1~Q4组),分组分析结果显示TyG Q2~Q4组、TG/HDL-C Q4组、TyHGB Q3、TyAGB Q4组、METS-IR Q3、METS-IR Q4组是患者术后发生MACEs的危险因素(P<0.05)。Kaplan-Meier生存曲线结果显示,不同TyG(χ2=17.428)、TG/HDL-C(χ2=41.682)、TyHGB(χ2=47.345)、METS-IR(χ2=104.233)四分位数患者发生MACEs的风险比较,差异有统计学意义(P<0.05)。RCS曲线结果表明,TG/HDL-C、TyHGB、METS-IR与MACEs发生非线性相关(P非线性<0.001,P<0.05);TyG与MACEs发生线性相关(P非线性=0.643,P<0.05)。ROC曲线分析结果显示,TyHGB、TyG、TG/HDL-C、METS-IR预测MASLD合并CHD患者PCI术后发生MACEs的ROC曲线下面积(AUC)分别为0.653(95%CI=0.611~0.696)、0.599(95%CI=0.553~0.644)、0.652(95%CI=0.608~0.695)和0.741(95%CI=0.702~0.780)。 结论 TyHGB、TyG、TG/HDL-C和METS-IR与MASLD合并CHD患者PCI术后MACEs的发生呈正相关,并可作为潜在的流行病学预测指标,其中METS-IR的预测效能最优。

Abstract:

Background

Metabolic dysfunction-associated steatotic liver disease (MASLD) is a steatotic liver disorder closely linked to metabolic dysregulation. Insulin resistance (IR) plays a key role in its pathophysiology and is considered a significant component of cardiometabolic risk.

Objective

To investigate the association between different surrogate indicators of IR and the occurrence of major adverse cardiovascular events (MACEs) after percutaneous coronary intervention (PCI) in patients with MASLD and coronary heart disease (CHD), and to identify simple predictive indicators suitable for this population.

Methods

A total of 958 patients diagnosed with MASLD and CHD who underwent PCI at Northern Jiangsu People's Hospital from January 1, 2019 to October 31, 2023, were retrospectively enrolled. Baseline data were collected, cardiac function was assessed by echocardiography, and liver status was evaluated by ultrasound. IR surrogate indicators were calculated based on laboratory results. Patients were followed up to collect the occurrence of postoperative MACEs. Cox proportional hazards regression models were used to explore prognostic factors. Receiver operating characteristic (ROC) curves were plotted to evaluate the predictive efficacy of IR surrogate indicators. Kaplan-Meier survival curves were drawn to compare cumulative survival rates, with Log-rank tests for group comparisons. Restricted cubic spline (RCS) curves were used to explore the nonlinear trends between IR indicators and prognosis.

Results

Based on follow-up results, patients were divided into the non-MACEs group (n=768) and the MACEs group (n=190). Significant differences were observed between the two groups in white blood cell count, neutrophil count, monocyte count, fasting plasma glucose (FPG), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), apolipoprotein A, apolipoprotein B, albumin, aspartate aminotransferase, TyHGB, TyG, TG/HDL-C, and METS-IR (P<0.05). Cox regression analysis showed that elevated TyG (HR=1.820, 95%CI=1.223-2.707) and METS-IR (HR=7.309, 95%CI=3.770-14.170) were risk factors for postoperative MACEs (P<0.05). Group analysis indicated that TyG Q2-Q4, TG/HDL-C Q4, TyHGB Q3-Q4, and METS-IR Q3-Q4 were risk factors for MACEs (P<0.05). Kaplan-Meier curves showed significant differences in MACEs risk across quartiles of TyG (χ2=17.428), TG/HDL-C (χ2=41.682), TyHGB (χ2=47.345), and METS-IR (χ2=104.233) (P<0.05). RCS curves indicated a nonlinear correlation of TG/HDL-C, TyHGB, and METS-IR with MACEs (Pnonlinear<0.001), while TyG showed a linear correlation (Pnonlinear=0.643). ROC analysis showed the AUC for TyHGB, TyG, TG/HDL-C, and METS-IR were 0.653(95%CI=0.611-0.696), 0.599(95%CI=0.553-0.644), 0.652(95%CI=0.608-0.695), and 0.741, respectively.

Conclusion

TyHGB, TyG, TG/HDL-C, and METS-IR are positively associated with the occurrence of MACEs after PCI in patients with MASLD and CHD and can serve as potential epidemiological predictive indicators, with METS-IR demonstrating the best predictive performance.
