摘　　要：目的探讨老年慢性心力衰竭(CHF)患者住院期间的营养不良风险及其与随访主要不良心脑血管事件(MACCE)的相关性。方法本研究为前瞻性队列研究。连续选取首都医科大学附属北京安贞医院2017年1月至2019年12月收治的老年CHF患者683例。入院24 h内应用2002年营养风险筛查量表(NRS-2002)评分进行营养不良风险筛查,根据结果分为高风险组(NRS-2002评分≥3分)和低风险组(NRS-2002评分<3分)。比较2组患者基线资料。随访2年,主要观察终点MACCE,为心血管死亡、因心力衰竭加重再入院、新发急性冠状动脉综合征和脑卒中的复合事件。采用Kaplan-Meier生存分析和Log-rank检验分析MACCE发生风险,单因素和多因素Cox回归分析临床指标与MACCE的相关性。结果683例老年CHF患者中,605例(88.6%)患者为低营养不良风险(低风险组)、78例(11.4%)患者为高营养不良风险(高风险组)。2组年龄、体重指数、心力衰竭病程、缺血性心力衰竭比例、糖尿病比例、慢性肾病比例、血红蛋白、C反应蛋白、白蛋白、N末端B型脑钠肽前体(NT-proBNP)、估算肾小球滤过率(eGFR)、左心室射血分数、左心室舒张末期内径水平、住院时间以及噻嗪类利尿剂和硝酸甘油使用比例比较,差异均有统计学意义(均P<0.05)。平均随访22.1个月,失访53例。随访期间,高风险组因心力衰竭加重再入院发生率和MACCE总发生率均高于低风险组(Log-rankχ^(2)=4.526、6.818,P=0.031、0.001)。多因素Cox回归分析结果显示,NRS-2002评分与MACCE发生风险呈正相关(风险比=1.715,95%置信区间:1.121~2.624),此外,年龄(风险比=1.506,95%置信区间:1.118~2.029)、体重指数(风险比=1.347,95%置信区间:1.102~1.647)、心力衰竭病程(风险比=1.559,95%置信区间:1.198~2.029)、糖尿病(风险比=1.481,95%置信区间:1.034~2.121)、白蛋白(风险比=1.392,95%置信区间:1.075~1.803)、NT-proBNP(风险比=2.017,95%置信区间:1.136~3.581)�Objective To explore the hospitalization malnutrition risk in elderly patients with chronic heart failure(CHF)and its correlation with major adverse cardiovascular and cerebrovascular events(MACCE)during follow-up.Methods It was a prospective cohort study.Totally 683 elderly patients with CHF admitted to Beijing Anzhen Hospital,Capital Medical University from January 2017 to December 2019 were selected consecutively.Within 24 h after admission,nutritional risk screening(NRS-2002)score was used to investigate the nutritional status of patients,and they were divided into high-risk group(NRS-2002 score≥3)and low-risk group(NRS-2002 score<3)according to the results of NRS-2002.Baseline data of patients were compared between the two groups.Followed-up for 2 years,the main end point was MACCE,a complex event of cardiovascular death,re-admission due to aggravated heart failure,new acute coronary syndrome(ACS)and stroke.Kaplan-Meier survival analysis and Log-rank test were used to analyze the risk of MACCE.Univariate and multivariate Cox regression analyses were used to evaluate the correlation between clinical indexes and MACCE.Results Among the 683 elderly patients with CHF,605 cases(88.6%)had low malnutrition risk(low-risk group)and 78 cases(11.4%)had high malnutrition risk(high-risk group).The age,body mass index,duration of heart failure,ischemic heart failure rate,diabetes mellitus rate,chronic kidney disease rate,hemoglobin,C-reactive protein,albumin,N-terminal pro-brain natriuretic peptide(NT-proBNP),estimated glomerular filtration rate(eGFR),left ventricular ejection fraction,left ventricular end diastolic diameter levels,length of stay,and application rates of thiazide diuretics and nitroglycerin were significantly different between the two groups(all P<0.05).The average follow-up was 22.1 months,and 53 cases were lost.During the follow-up period,the rate of re-admission due to aggravated heart failure and totally rate of MACCE in the high-risk group were higher than those in the low-risk group(Log-rankχ^(2)
