摘　　要：目的探讨老年慢性心力衰竭(CHF)患者血清嗜铬粒蛋白A(CgA)和热休克转录因子1(HSF1)的水平变化与心肌重构及心肌损伤的关系。方法选择2019年1月至2022年5月太原市中心医院收治的老年CHF患者165例(疾病组),其中纽约心脏病协会心功能分级Ⅰ级28例,Ⅱ级29例,Ⅲ级65例和Ⅳ级43例。收集同期本院健康志愿者80例(对照组)。检测2组入院血清CgA和HSF1水平,心肌重构和心肌损伤指标,用Pearson分析血清CgA和HSF1与心肌重构及心肌损伤的相关性。随访1年,失访6例,根据是否发生主要不良心血管事件(MACE)分为MACE组51例和非MACE组108例。用单因素和多因素logistic回归分析,使用ROC曲线分析血清CgA和HSF1对MACE的预测价值。结果疾病组血清CgA、左心室质量指数(LVMI)、左心室收缩末期容积(LVESV)、左心室后壁厚度(LVPWT)、肌钙蛋白I(cTnI)、肌酸激酶同工酶(CK-MB)和N末端B型钠尿肽前体(NT-proBNP)水平显著高于对照组,HSF1和左心室射血分数(LVEF)显著低于对照组,差异有统计学意义(P<0.01)。Pearson相关性分析显示,血清CgA与LVEF呈负相关,与LVMI、LVESV、LVPWT、cTnI、CK-MB和NT-proBNP呈正相关(P<0.01);血清HSF1与LVEF呈正相关,与LVMI、LVESV、LVPWT、cTnI、CK-MB和NT-proBNP呈负相关(P<0.01)。多因素logistic回归分析显示,CgA、HSF1、LVEF、LVMI、LVESV、LVPWT和cTnI是老年CHF患者MACE发生的影响因素(P<0.05,P<0.01)。ROC曲线分析显示,血清CgA截断值为387.55μg/L,敏感性为74.51%,特异性为71.30%,曲线下面积为0.802(95%CI:0.751~0.855);血清HSF1截断值为2.34 ng/L,敏感性为74.51%,特异性为69.44%,曲线下面积为0.760(95%CI:0.707~0.812)。结论老年CHF患者血清CgA和HSF1水平与心肌重构及心肌损伤有密切关联,可作为预测MACE的有力工具。Objective To investigate the relationship of changes in serum chromogranin A(CgA)and heat shock transcription factor 1(HSF1)levels with cardiac remodeling and myocardial injury in elderly patients with chronic heart failure(CHF).Methods A total of 165 elderly CHF patients admitted to our hospital from January 2019 to May 2022 were selected as the disease group,and according to NYHA classification,they were divided into ClassⅠ(28 patients),Ⅱ(29 patients),Ⅲ(65 patients)andⅣ(43 patients)subgroups.Another 80 healthy individuals taking physical examination in our hospital during the same period were enrolled as the control group.The serum CgA and HSF1 levels were detected,and the indicators of cardiac remodeling and myocardial injury were collected at admission in the two groups.The correlation of serum CgA and HSF1 levels with cardiac remodeling and myocardial injury was determined with Pearson correlation analysis.During 1 year's follow-up,6 cases were lost,and the left 159 patients were divided into MACE group(51 cases)and non-MACE group(108 cases)according to whether MACE occurred.Univariate and multivariate logistic regression analyses were used to analyze the influencing factors of MACE,and ROC curve was plotted to analyze the predictive value of serum CgA and HSF1 levels for MACE.Results The disease group had significantly higher left ventricular mass index(LVMI),left ventricular end-systolic volume(LVESV),left ventricular posterior wall thickness(LVPWT),serum levels of CgA,cardiac troponin I(cTnI),creatine kinase isoenzyme(CK-MB)and N-terminal B-type natriuretic peptide precursor(NT-proBNP),and obviously lower HSF1 level and left ventricular ejection fraction(LVEF)when compared with the control group(P<0.01).Pearson correlation analysis showed that serum CgA level was negatively correlated with LVEF and positively with LVMI,LVESV,LVPWT,and serum levels of cTnI,CK-MB and NT-proBNP(P<0.01);serum HSF1 level was positively correlated with LVEF and negatively with LVMI,LVESV,LVPWT,and serum cTnI,CK-MB and N
