摘要
目的探讨血清补体C1q肿瘤坏死因子相关蛋白3(CTRP3)浓度水平与瓣膜性心脏病(VHD)和扩张型心肌病(DCM)所合并的心力衰竭的相关性。方法选取的病例是由2016年11月至2017年1月本院收治的59例VHD和DCM导致的心力衰竭患者,患者心功能均为美国纽约心脏病协会(NYHA)分级Ⅱ~Ⅳ级,另选取50例同期来院的健康体检者作为健康对照组。收集两组患者一般临床资料,采用酶联免疫吸附法测定入院时采集的患者血清中CTRP3的浓度,进行统计学分析比较两组CTRP3的水平,并比较不同NYHA分级、不同病因所导致的心力衰竭患者的血清CTRP3水平,分析血清CTRP3水平与血清N末端B型利钠肽原(NT-proBNP)浓度和左室射血分数(LVEF)值的相关性。结果病例组患者血清CTRP3浓度较对照组显著升高,且NYHA心功能分级等级越高,血清CTRP3浓度越高,差异有统计学意义(P <0.05)。心衰患者血清CTRP3水平与血清NT-proBNP水平呈线性正相关,与LVEF值呈线性负相关,有统计学意义(P <0. 05)。DCM患者血清CTRP3水平较VHD患者高,差异有统计学意义(P <0.05)。结论慢性心力衰竭患者血清CTRP3水平显著升高,且随心衰程度加重而升高,不同病因导致的心衰血清CTRP3升高程度也存在差异。
Objective To investigate the relationship between serum CTRP3 level and heart failure in patients with valvular heart disease( VHD) or dilated cardiomyopathy( DCM). Methods A total of 59 patients with heart failure caused by VHD or DCM admitted to our hospital from November 2016 to January 2017 were selected. The heart function of the patients was New York Heart Association( NYHA) class 2-4. Another 50 healthy people were selected as the control group. Clinical data of the two groups were collected.Concentration of CTRP3 in the serum was determined by enzyme-linked immunosorbent assay( ELISA). Patients with heart failure under different NYHA classes and from different causes were compared respectively. Serum CTRP3 levels were analyzed for correlation with serum NT-proBNP concentrations and left ventricular ejection fraction( LVEF) values. Results Serum CTRP3 levels in patients were significantly higher than those in the control group.The patients under higher NYHA classes had higher serum CTRP3 levels( P <0.05). There was a linear positive correlation between serum CTRP3 level and serum NT-proBNP level in patients with heart failure,but a linear negative correlation with LVEF( P <0.05). Serum CTRP3 levels in DCM patients were significantly higher than those in VHD patients( P <0.05). Serum CTRP3 levels in DCM patients were higher than those in VHD patients,and the difference was statistically significant( P <0.05). Conclusion Serum CTRP3 levels in patients with chronic heart failure significantly increased with the severity of heart failure. There were also differences in the degree of CTRP3 elevation caused by heart failure with different causes.
