目的:探讨超声心动图联合血清高敏C反应蛋白(hs-CRP)、N末端B型钠尿肽前体(NT-proBNP)水平对冠心病心衰患者心功能的评估价值。方法:选择2021年11月至2022年11月北京市大兴区人民医院收治的306例冠心病心衰患者作为研究组,其中纽约心脏病协会(NYHA)心功能分级中Ⅱ级144例,Ⅲ级103例,Ⅳ级59例。另选同期在本院进行体检的108名健康体检者作为健康对照组,对所有受检者均进行NYHA心功能分级,采用超声心动图检测左室舒张末容积(LVEDV)、左室收缩末容积(LVESV)、左室射血分数(LVEF)、峰值射血率(PER)及峰值充盈率(PFR),检测所有受试者的NT-proBNP、hs-CRP水平,采用受试者工作特征(ROC)曲线分析LVEDV、LVESV、LVEF、PER、PFR、hs-CRP及NT-proBNP各指标单独检测及联合检测的价值。结果:研究组LVEDV(122.69±18.24)ml、LVESV(70.79±10.03)ml明显高于健康对照组(92.27±15.22)ml、(33.16±7.22)ml;LVEF(42.26±5.13)%、PER(2.49±0.22)EDV/s及PFR(1.79±0.26)EDV/s明显低于健康对照组(69.34±5.27)%、(3.56±0.27)EDV/s及(2.59±0.23)EDV/s,差异均有统计学意义(t=15.526、35.837、46.828、40.825、28.302,P<0.05);研究组hs-CRP和NT-proBNP水平明显高于健康对照组,差异有统计学意义(t=88.000、29.099,P<0.05);Ⅱ/Ⅲ级患者的LVEDV、LVESV明显低于IV级,LVEF、PER及PFR明显高于IV级,差异有统计学意义(t=53.391、92.658、32.140、240.474、116.921,P<0.05);Ⅱ/Ⅲ级患者hs-CRP、NT-proBNP水平明显低于Ⅳ级,差异有统计学意义(t=41.037、5.955,P<0.05);ROC曲线分析结果显示,LVEDV、LVESV、LVEF、PER、PFR、hs-CRP及NT-proBNP各指标单独检测及联合检测的灵敏度分别为45.00%、50.00%、70.00%、70.00%、75.00%、70.00%和90.00%,特异性分别为76.70%、57.00%、82.60%、44.20%、58.10%、52.30%和96.50%。LVEDV、LVESV、LVEF、PER、PFR、hs-CRP及NT-proBNP和联合检测的曲线下面积(AUC)分别为0.592(95%CI:0.441~0.743)、0.615(95%CI:0.468~0.761)、0.766(95%CI:0.634~0.899)、0.717(95%CI:0.575~0.860)、0.674(95%CI:0.536~0.812)、0.734(95%CI:0.592~0.876)、0.581(95%CI:0.469~0.694)和0.978(95%CI:0.947~1.000)。结论:冠心病心衰患者血清hs-CRP、NT-proBNP水平与左心功能参数均发生了相应的改变,且上述指标对冠心病心衰心功能具有较高的评估价值,联合评估的价值更高。
Objective:To explore the assessment value of echocardiogram combined with serum high-sensitivity C-reactive protein(hs CRP)and N-terminal pro brain natriuretic peptide(NT proBNP)levels on cardiac function of patients with coronary heart failure.Methods:A total of 306 patients with coronary heart failure admitted to Beijing Daxing District People's Hospital from November 2021 to November 2022 were selected as the study group.Among of them,144 cases were grade II,103 cases were grade III and 59 cases were grade IV as the classification of New York Heart Association(NYHA)for cardiac function.A total of 108 healthy examinees who underwent physical examinations in our hospital during the same period were selected as the healthy control group.All examinees were classified as the NYHA for cardiac function,and left ventricular end diastolic volume(LVEDV),left ventricular end systolic volume(LVESV),left ventricular ejection fraction(LVEF),peak ejection rate(PER)and peak filling rate(PFR)of them were measured by echocardiogram.The NT proBNP and hs CRP levels of all examinees were measured.Receiver operating characteristic(ROC)curve was used to analyze the values of single LVEDV,LVESV,LVEF,PER,PFR,hs CRP and NT-proBNP,and the combination of them.Results:LVEDV(122.69±18.24)ml and LVESV(70.79±10.03)ml of the study group were significantly higher than(92.27±15.22)ml and(33.16±7.22)ml of the healthy control group,and the LVEF(42.26±5.13)%,PER(2.49±0.22)EDV/s and PFR(1.79±0.26)EDV/s of the study group were significantly lower than(69.34±5.27)%,(3.56±0.27)EDV/s,and(2.59±0.23)EDV/s of the healthy control group,with statistical significances(t=15.526,35.837,46.828,40.825,28.302,P<0.05),respectively.The levels of hs CRP and NT proBNP of the study group were significantly higher than those of the healthy control group,with statistical significance(t=88.000,29.099,P<0.05),respectively.The LVEDV and LVESV of grade II/III patients were significantly lower than those of grade IV patients,while LVEF,PER and PFR of grade II/III patients were significantly higher than those of grade IV patients,with statistically significant differences(t=53.391,92.658,32.140,240.474,116.921,P<0.05),respectively.The levels of hs CRP and NT proBNP of grade II/III patients were significantly lower than those in grade IV patients,with statistical significance(t=41.037,5.955,P<0.05),respectively.The results of ROC curve analysis showed that the sensitivities of single LVEDV,LVESV,LVEF,PER,PFR,hs CRP,NT proBNP and the combined examination of them were respectively 45.00%,50.00%,70.00%,70.00%,75.00%,70.00%and 90.00%,and the specificities of them were respectively 76.70%,57.00%,82.60%,44.20%,58.10%,52.30%and 96.50%.The area under curve(AUC)values of LVEDV,LVESV,LVEF,PER,PFR,hs CRP,NT proBNP and the combined examination of them were 0.592(95%CI:0.441-0.743),0.615(95%CI:0.468-0.761),0.766(95%CI:0.634-0.899),0.717(95%CI:0.575-0.860),0.674(95%CI:0.536-0.812),0.734(95%CI:0.592-0.876),0.581(95%CI:0.469-0.694)and 0.978(95%CI:0.947-1.000),respectively.Conclusion:The serum hs CRP,NT proBNP levels and function parameters of left heart in patients with coronary heart failure have occurred corresponding changes,and the above indicators have higher assessment value for the heart function of coronary heart failure,and the value of combined assessment is higher.
