Objective To investigate the association between the serum creatinine/cystatin C ratio (SCr/Cys C) as a Sarcopenia index (SI) and the incidence of in-hospital adverse events in patients with acute myocardial infarction (AMI) undergoing emergency percutaneous coronary intervention (PCI). Additionally, we evaluate the predictive efficacy of the SI in predicting major adverse cardiovascular events (MACEs) during hospitalization. Methods A total of 306 patients with AMI who underwent emergency PCI in the 904th Hospital of PLA Joint Logistics Support Force from January 2020 to March 2023 were consecutively included in this retrospective analysis. Patients were divided into two groups based on the occurrence of MACEs during hospitalization: MACEs group (n=43) and non-MACEs group (n=263). Clinical characteristics and pre-PCI laboratory test results were collected. Univariate and multivariate logistic regression analyses were performed to identify independent risk factors for MACEs. The predictive performance of SI was assessed using receiver operating characteristic (ROC) curve analysis. Results The incidence of in-hospital MACEs in AMI patients was 14.1%.The results of the independent samples t-test showed that the SI level in MACEs group was significantly lower than that in non-MACEs group, with a statistically significant difference (P<0.001). The results of the multivariate logistic regression analysis suggested that new-onset atrial fibrillation, Killip class 2-4, SI, and TG were independent risk factors for in-hospital adverse events after emergency PCI. The ROC curve results showed that the predictive value of SI (AUC=0.741, 95%CI 0.666-0.816) using the SCr/Cys C ratio was superior to that of single Cys C (AUC=0.658, 95%CI 0.570-0.746) for predicting post-PCI MACEs, with a statistically significant difference (P<0.05), and the optimal cutoff value for SI was 78.14. After stratifying SI based on the cutoff value, the results of the independent samples t-test showed that compared to the higher SI group, the lower SI group had a higher occurrence of specific adverse events such as heart failure (P<0.001), malignant arrhythmias (P=0.009), and strokes (P=0.003), with statistically significant differences. Conclusions The results highlight SI as an independent risk factor for MACEs during hospitalization after emergency PCI in AMI patients. Furthermore, SI has proven to be an effective prognostic index for patient outcomes.

目的 探讨血清肌酐/胱抑素C比值(SCr/Cys C)作为肌肉减少指数(SI),与急性心肌梗死(AMI)患者行急诊经皮冠状动脉介入治疗(PCI)后,发生院内不良事件之间的相关性,并评估SI预测发生院内主要不良心血管事件(MACEs)的效能。方法 选取2020年1月-2023年3月在解放军联勤保障部队第904医院接受急诊PCI的306例AMI患者进行回顾性分析。根据患者术后住院期间是否发生MACEs分为MACEs组(n=43)与非MACES组(n=263)。收集两组患者的临床特征和急诊PCI术前实验室检查结果并进行比较。对有差异的指标进一步采用单因素和多因素logistic回归分析影响AMI患者PCI术后住院期间发生MACEs的独立危险因素,并绘制受试者工作特征(ROC)曲线评价SI的预测效能。结果 AMI患者住院期间MACEs发生率为14.1%。术前MACEs组SI水平明显低于非MACES组,差异有统计学意义(P<0.001)。通过多次校正多因素logistic回归分析结果显示,新发房颤、Killip 2-4级、SI、三酰甘油是急诊PCI术后院内不良事件的独立危险因素。ROC曲线结果显示,采用SCr/Cys C比值计算的SI(AUC=0.741,95%CI 0.666~0.816)对急诊PCI术后MACEs的预测价值优于单项Cys C(AUC=0.658,95%CI 0.570~0.746),差异有统计学意义(P<0.05),且SI的最佳截断值为78.14。根据截断值对SI分层后,与较高的SI组相比,较低的SI组具体不良事件心力衰竭(P<0.001)、恶性心律失常(P=0.009)、卒中(P=0.003)的发生更多,差异有统计学意义。结论 SI是AMI患者行急诊PCI术后住院期间发生MACEs的独立危险因素,是预测患者预后的有效指标。

目的 探讨血清肌酐/胱抑素C比值(SCr/Cys C)作为肌肉减少指数(SI),与急性心肌梗死(AMI)患者行急诊经皮冠状动脉介入治疗(PCI)后,发生院内不良事件之间的相关性,并评估SI预测发生院内主要不良心血管事件(MACEs)的效能。方法 选取2020年1月-2023年3月在解放军联勤保障部队第904医院接受急诊PCI的306例AMI患者进行回顾性分析。根据患者术后住院期间是否发生MACEs分为MACEs组(n=43)与非MACES组(n=263)。收集两组患者的临床特征和急诊PCI术前实验室检查结果并进行比较。对有差异的指标进一步采用单因素和多因素logistic回归分析影响AMI患者PCI术后住院期间发生MACEs的独立危险因素,并绘制受试者工作特征(ROC)曲线评价SI的预测效能。结果 AMI患者住院期间MACEs发生率为14.1%。术前MACEs组SI水平明显低于非MACES组,差异有统计学意义(P<0.001)。通过多次校正多因素logistic回归分析结果显示,新发房颤、Killip 2-4级、SI、三酰甘油是急诊PCI术后院内不良事件的独立危险因素。ROC曲线结果显示,采用SCr/Cys C比值计算的SI(AUC=0.741,95%CI 0.666~0.816)对急诊PCI术后MACEs的预测价值优于单项Cys C(AUC=0.658,95%CI 0.570~0.746),差异有统计学意义(P<0.05),且SI的最佳截断值为78.14。根据截断值对SI分层后,与较高的SI组相比,较低的SI组具体不良事件心力衰竭(P<0.001)、恶性心律失常(P=0.009)、卒中(P=0.003)的发生更多,差异有统计学意义。结论 SI是AMI患者行急诊PCI术后住院期间发生MACEs的独立危险因素,是预测患者预后的有效指标。

Objective To investigate the association between the serum creatinine/cystatin C ratio (SCr/Cys C) as a Sarcopenia index (SI) and the incidence of in-hospital adverse events in patients with acute myocardial infarction (AMI) undergoing emergency percutaneous coronary intervention (PCI). Additionally, we evaluate the predictive efficacy of the SI in predicting major adverse cardiovascular events (MACEs) during hospitalization. Methods A total of 306 patients with AMI who underwent emergency PCI in the 904th Hospital of PLA Joint Logistics Support Force from January 2020 to March 2023 were consecutively included in this retrospective analysis. Patients were divided into two groups based on the occurrence of MACEs during hospitalization: MACEs group (n=43) and non-MACEs group (n=263). Clinical characteristics and pre-PCI laboratory test results were collected. Univariate and multivariate logistic regression analyses were performed to identify independent risk factors for MACEs. The predictive performance of SI was assessed using receiver operating characteristic (ROC) curve analysis. Results The incidence of in-hospital MACEs in AMI patients was 14.1%.The results of the independent samples t-test showed that the SI level in MACEs group was significantly lower than that in non-MACEs group, with a statistically significant difference (P<0.001). The results of the multivariate logistic regression analysis suggested that new-onset atrial fibrillation, Killip class 2-4, SI, and TG were independent risk factors for in-hospital adverse events after emergency PCI. The ROC curve results showed that the predictive value of SI (AUC=0.741, 95%CI 0.666-0.816) using the SCr/Cys C ratio was superior to that of single Cys C (AUC=0.658, 95%CI 0.570-0.746) for predicting post-PCI MACEs, with a statistically significant difference (P<0.05), and the optimal cutoff value for SI was 78.14. After stratifying SI based on the cutoff value, the results of the independent samples t-test showed that compared to the higher SI group, the lower SI group had a higher occurrence of specific adverse events such as heart failure (P<0.001), malignant arrhythmias (P=0.009), and strokes (P=0.003), with statistically significant differences. Conclusions The results highlight SI as an independent risk factor for MACEs during hospitalization after emergency PCI in AMI patients. Furthermore, SI has proven to be an effective prognostic index for patient outcomes.

急性心肌梗死(acute myocardial infarction,AMI)是心血管疾病中较严重的类型,在世界范围内发病率和病死率均较高[1]。肥胖作为冠心病的危险因素,既往许多国内外大型研究均提示,肥胖与心血管疾病病死率增高有关[2-3],但新近有研究发现肥胖在心血管疾病住院患者尤其是老年患者中起保护作用[4-5]。基于体重指数(BMI)的研究发现,BMI增高与较低的住院病死率独立相关,超重组心血管全因死亡率与轻度肥胖组比较明显降低,且BMI为35 kg/m2的冠心病患者死亡风险降低[6-7]。这些研究表明,BMI缺乏对体脂和肌肉质量的描述,在没有超重的情况下,脂肪量的增加、肌肉质量的下降,以及脂肪向腹部重新分布均可发生。2010年,欧洲老年人肌肉减少症工作组(EWGSOP)发布了肌肉减少症的定义[8],提示肌肉减少症是一种肌肉衰竭疾病,其根源是终生不断累积的不良肌肉变化。而众多研究证实,肌肉减少症与各种心血管疾病的风险[9-14]和病死率增高[15-17]相关。目前判断肌肉减少症的方法多依赖于全身肌肉质量即阑尾肌肉质量、磁共振成像(MRI)、双能X线吸收仪(DXA)、生物电阻抗分析(BIA)等工具实现[18]。这些检测方法和工具或多或少受到场地、经济成本及从业人员的限制,难以在临床工作中广泛开展。因此,基于血清肌酐(SCr)与胱抑素C(Cys C)的比值的计算—肌肉减少指数(sarcopenia index,SI)应运而生[19]。近期已有报道,较低的SI是阻塞性冠状动脉疾病(CAD)患者发生长期主要不良心血管事件(major adverse cardiovascular events,MACEs)的独立危险因素[10]。然而SI对短期不良临床事件的发生是否有意义仍有待研究,因此本研究旨在探寻SI与AMI患者经皮冠状动脉介入治疗(percutaneous coronary intervention,PCI)术后短期院内MACEs发生的关系,并挖掘其预测价值。
收集2020年1月-2023年3月就诊于联勤保障部队第904医院心血管内科首次发生急性心肌梗死(AMI)并接受急诊冠状动脉造影术的306例患者进行回顾性分析。AMI的诊断参考2022年《综述:急性冠脉综合征的诊断与治疗》指南推荐[20]。纳入标准:(1)年龄18~80岁,确诊为AMI后行PCI治疗;(2)神志清楚,可以交流沟通,无严重神经及精神类疾病。所有受试者入院后均规范服用阿司匹林、替格瑞洛/氯吡格雷双抗治疗。排除标准:(1)既往有慢性冠心病、陈旧性心肌梗死、脑梗死病史,或行PCI、冠状动脉旁路移植术病史;(2)急性肾损伤及终末期肾病(ESRD),定义为血肌酐(Scr)≥110 μmol/L或肾小球滤过率(GFR)≤15 ml/(min.1.73 m2)或已接受肾脏替代治疗;(3)严重肝脏疾病;(4)存在免疫性疾病、恶性肿瘤、血液系统疾病或严重精神功能障碍;(5)缺少研究所需临床数据。观察患者入院期间是否发生MACEs,发生MACEs的43例AMI患者设为MACEs组;未发生MACEs的263例AMI患者设为非MACEs组。本研究获解放军联勤保障部队第904医院伦理委员会审批(20231201),所有患者均已签署知情同意书。
所有基础数据通过详细的病历回顾获得,包括患者的临床人口统计数据,如年龄、性别、高血压病史、糖尿病史、吸烟史。患者急诊PCI前空腹采集肘静脉血,检测血常规:血红蛋白(Hb)、红细胞计数(RBC)、白细胞计数(WBC)、血小板计数(PLT)、淋巴细胞计数(LY)、单核细胞计数(MONO)等、凝血功能[包括D-二聚体、血浆纤维蛋白原(FIB)];采用全自动生化分析仪(美国Beckman公司)检测白蛋白(ALB)、SCr、Cys C、β2微球蛋白(β2(HDL-C),并计算SI值[SI=(SCr/Cys C)×100];采用彩色多普勒超声诊断仪(飞利浦EPIQ5型)检测左室射血分数(LVEF)。冠脉病变分析方法采用标准Judkins法行冠脉造影,冠脉狭窄程度及病变血管支数由两名以上介入专科医师根据造影结果进行判断,并使用Gensini冠脉评分评价冠脉病变严重程度(轻度狭窄,Gensini评分≤58分;重度狭窄,Gensini评分>58分)。
主要观察终点为AMI患者急诊PCI术后住院期间是否发生MACEs,包括心力衰竭、再发心肌梗死/心绞痛、恶性心律失常、卒中及全因死亡。
对比分析两组患者的一般临床数据、生化指标、血常规指标及冠状动脉造影结果,将有差异的参数纳入单因素logistic回归分析。对单因素logistic回归分析中有统计学意义(P<0.05)的参数进行共线性诊断,排除共线性指标后进行多因素logistic回归分析,得出AMI患者发生院内MACEs的独立危险因素;进一步根据SI截断值分层分析研究指标与具体院内MACEs之间的差异。最后比较研究指标对AMI患者急诊PCI术后住院期间发生MACEs的预测效能。
采用SPSS 27.0软件进行统计分析。计量资料中正态分布且方差齐者以$\bar{x}±s$表示,两组间比较采用独立样本t检验;偏态分布资料以M(Q1Q3)表示,组间比较采用非参数检验。计数资料以例(%)表示,组间比较采用χ2检验。将一般资料纳入单因素logistic回归分析,将有统计学意义的参数排除共线性后进行多因素logistic回归分析。采用Spearman相关分析评估SI与PCI术后各个不良事件的相关性。采用MedCalc15.2.2统计软件绘制受试者工作特征(ROC)曲线。P<0.05为差异有统计学意义。
与非MACEs组比较,MACEs组患者的年龄大,Killip 2-4级比例高,有糖尿病病史、新发房颤、冠脉多支病变及冠脉狭窄重度的患者比例高,Cys C、β2-MG、D-二聚体、FIB水平明显升高,而身高、体重、左室射血分数(LVEF)、Hb、RBC、SI、ALB、ApoA-1、HDL-C、TG水平明显降低,差异均有统计学意义(P<0.05),而两组间Scr差异无统计学意义(P=0.358,表1)。
筛选出一般资料中有差异的参数(P<0.1)纳入单因素logistic回归分析,结果显示,年龄、性别、糖尿病、新发房颤、Killip 2-4级、病变血管支数、Gensini分级、Hb、RBC、ALB、Cys C、β2-MG、ApoA-1、HDL-C、TG、FIB及SI是AMI患者急诊PCI术后院内不良事件发生的危险因素(P<0.05,表2)。
选择单因素logistic分析结果中有统计学意义的指标(P<0.05),经共线性诊断提示各指标方差膨胀因子均<10,容忍度>0.1,将新发房颤、Killip 2-4级、LVEF、Hb、RBC、ALB、Cys C、β2-MG、ApoA-1、HDL-C、TG、FIB、SI纳入多因素logistic回归分析得到模型1。其中,SI(OR=0.949,95%CI 0.920~0.979,P<0.001)是AMI患者急诊PCI术后院内不良事件发生的独立危险因素。进一步通过校正心肌梗死类型、性别、年龄、身高、体重、高血压病、糖尿病、吸烟史等参数构建模型2,其中,新发房颤、Killip 2-4级、β2-MG、TG、FIB、SI是AMI患者急诊PCI术后院内不良事件发生的独立危险因素。最后再进一步通过校正冠脉血管病变支数及冠脉狭窄情况构建模型3,结果显示,新发房颤、Killip 2-4级、SI、TG仍然是AMI患者急诊PCI术后院内不良事件的独立危险因素(P<0.05,表3)。
通过上述分析,SI与AMI患者急诊PCI术后院内不良事件发生呈负相关,因此取SI倒数。采用ROC曲线评估SI倒数和Cys C的预测价值,并对曲线下面积(AUC)进行比较。SI倒数与Cys C的AUC分别为0.741(95%CI 0.666~0.816)和0.658(95%CI 0.570~0.746)。SI与Cys C的敏感度和特异度分别为60.5%、77.6%和51.2%、74.1%,SI的最佳截断值为78.14(图1)。
通过上述SI截断值将患者分为低SI组(SI<78.14)与高SI组(SI≥78.14)。住院期间,低SI组患者的住院MACEs发生率明显高于高SI组(P<0.001)。而在具体的住院MACEs中,高SI组的心力衰竭(P<0.001)、恶性心律失常(P=0.009)、卒中(P=0.003)发生率明显低于低SI组,但两组间再发心肌梗死/心绞痛和全因死亡发生率差异无统计学意义(P>0.05,表4)。
心血管疾病已成为全球性的公共卫生问题,AMI则是心血管疾病中比较严重的高病死率疾病,直接威胁患者的健康[20-21]。近年来,虽然随着急诊PCI的推广普及和医师技术的提升,再灌注治疗率逐年上升,在很大程度上降低了AMI患者的病死率[22-23],然而患者的院内MACEs发生率并未明显下降。因此,大量研究在血清学、影像学、药理学和各种评分量表等方面探究影响院内MACEs发生的因素[24-27]。在日常实践中,年龄或慢性基础性疾病相关的冠状动脉事件可能促成心肌梗死发生已成为共识。然而,在较年轻的患者中,也可能因肌肉减少或质量下降出现相关临床疾病[27]。SI通过Scr/Cys C比值这种简易方法获得的预测不良事件发生的生物标志物有助于辅助临床医师及护理工作者识别并重点关注高危患者,从而改善AMI患者院内短期临床预后。
本研究发现,传统指标BMI对AMI患者是否发生院内MACEs的差异无统计学意义;而SI不仅差异有统计学意义,且多因素分析显示,SI是患者院内MACEs发生的独立危险因素,且较低的SI与院内MACEs的发生明显相关;提示BMI是缺乏区分体脂与肌肉质量的局限性指标,与健康人相比,应充分考虑AMI患者的肌肉质量。此外,非MACEs组的患者较MACEs组的患者更年轻,且男性居多,笔者认为与患者肌肉质量密切相关[28]。随着年龄的增长,肌肉质量逐渐下降。
笔者总结了3种AMI与SI之间的关系推断:(1)炎症和氧化应激在AMI的各个时期均发挥关键作用,并与缺血再灌注损伤、心脏重构不良、梗死面积和预后不良相关[29];研究表明,白细胞介素-6(IL-6)水平升高可促进肌肉的分解代谢和肌肉萎缩[30];活性氧(ROS)在引起血管收缩,促使动脉高血压、动脉粥样硬化斑块形成的同时,累积的ROS可通过促进肌肉水解而导致肌肉减少[31]。在既往研究的慢性炎症患者中观察到较高的Cys C水平,故而较低的Scr/Cys C水平与炎症有关[32]。(2)肌肉作为分泌器官,其肌肉纤维产生、表达和释放的肌因子对心血管是有益的[33]。(3)肌肉减少症的病理生理不仅涉及正常衰老相关的躯体功能损害,且可能与心肌梗死具有相似的危险因素[34]。此外,本研究还发现MACEs组患者既往有糖尿病病史者更多,这与许多近期关于糖尿病与SI的研究高度符合[32,35-36];西班牙一项观察性研究发现,49.5%的心房颤动患者会出现肌肉减少症[37]。病理学上,有研究纳入320例肌肉减少症患者发现其心传导系统的纤维化增加[38]。此外,肌肉减少也与左室舒张功能受损有关[39],并可能导致心房颤动的发生[40]
由于临床多种因素可对AMI患者急诊PCI术后院内MACEs产生影响,本研究采取分级建模的方法检测SI的评估价值。其中,构建的模型2校正了心肌梗死类型、性别、年龄、身高、体重、高血压、糖尿病、吸烟史等对SI患者急诊PCI预后有明显影响的临床因素,结果发现,新发房颤、Killip 2-4级、β2-MG、TG、FIB、SI是急诊PCI术后院内MACEs的独立危险因素。随后进一步校正了冠脉病变血管数和冠脉狭窄程度得到模型3,结果仍显示SI是稳定的急诊PCI术后院内MACEs的预测因子。此外,本研究发现,在具体不良事件中,与高SI组比较,低SI组更易发生心力衰竭、恶性心律失常、卒中(P<0.05),而再发心肌梗死/心绞痛及全因死亡差异无统计学意义(P>0.05)。本研究还发现,新发房颤、Killip分级、TG也与院内MACEs的发生密切相关,与Fauchier等[41]的早期研究结论一致:AMI后30 d内首次记录的房颤与死亡和缺血性卒中的风险独立相关,高于无房颤或先前已有房颤的患者。血清TG水平与PCI治疗ST段抬高心肌梗死(STEMI)患者的院内死亡和晚期结局呈负相关[42]
有研究显示,血清Cys C水平可作为各种心血管疾病患者短期和长期不良结局的预测因子[43-46]。其中,Budano等[46]建议在行冠状动脉造影前应先测定Cys C的基线水平,并提出Cys C是排除随后发生急性肾损伤和长期不良事件的有力指标。本研究进一步分析发现,在AMI患者中,由Scr/Cys C衍生的SI指标具有更好的短期预测价值。而SCr是一种由肌肉释放的内源性产物,其血药浓度依赖于肌肉质量,但受肾功能的影响[32]。因此,本研究在初始纳入标准中便排除了SCr≥110 μmol/L的患者,以避免肾功能不全对冠状动脉的影响。
综上所述,本研究发现,SI是AMI患者急诊PCI术后院内MACEs的独立危险因素,且SI水平较低者发生心力衰竭、恶性心律失常、卒中的风险较高,在预测住院期间不良事件的发生方面优于单独测量Cys C水平。但本研究仍存在一定的局限性:(1)为单中心回顾性设计,可能存在选择性偏倚;(2)血液参数均为急诊PCI术前的单次采样,对于多次采样或PCI手术前后的参数水平未进行动态水平监测;(3)未纳入其他用于评估营养状况的指标,如老年营养风险指数、控制营养状态评分和预后营养指数等,无法比较这些不同指标对住院MACEs发生的预测效果。因此,未来仍需通过多中心、大样本的前瞻性研究和长期随访来探讨SI对AMI患者急诊PCI术后住院期间及远期发生MACEs的预测价值。笔者将在后续的研究工作中对患者入院后不同时间节点,尤其是PCI术前及术后不同时间点进行多次采血分析比较,以探讨SI的动态变化对AMI患者急诊PCI术后住院期间及远期MACEs的预测价值。
