目的 评价左心衰竭患者的N末端A型利钠肽原(NT-proANP)、N末端B型利钠肽原(NT-proBNP)和N末端C型利钠肽原(NT-proCNP)分别与临床NYHA心功能分级和超声心动图所测指标的相关性.方法 使用酶联免疫测定的方法测定112例左心衰竭患者(心衰组)和44例正常人(对照组)的血浆NT-proANP、NT-proBNP和NT-proCNP值,并分别与临床NYHA分级、左房内径(LAD)、左室舒张末内径(LVEDD)和左室射血分数(LVEF)进行相关性分析.结果 心衰组的NT-proANP、NT-proBNP、NT-proCNP均显著高于对照组(均为P＜0.05).心衰患者NT-proANP、NT-proBNP和NT-proCNP均两两相关.NT-proANP与NT-proBNP的相关性最强(r=0.790,P=0.000),而NT-proCNP分别与NT-proBNP(r=0.278,P=0.003)和NT-proANP(r=0.236,P=0.012)相关性较弱.单因素分析NT-proANP、NT-proBNP和NT-proCNP与超声心动图指标相关性的结果显示:NT-proANP、NT-proBNP均分别与LAD、LVEDD呈正相关(均为P＜0.05),与LVEF呈负相关(均为P＜0.05).但NT-proCNP未见与LAD、INEDD、INEF有明显相关性.在心衰组,分别引入包括年龄、性别、NYHA分级、超声心动图所测LAD、LVEDD、LVEF共6个因素进行多元逐步回归分析,结果NYHA、LVEF、LAD、年龄与NT-proANP独立相关,NYHA、LVEF、年龄与NT-proBNP独立相关,而NT-proCNP未见与上述因素的相关性.结论 心衰患者血浆NT-proANP、NT-proBNP和NT-proCNP的水平均显著升高,且三者两两相关.不论是单因素还是多元回归分析,NT-proCNP未见与心功能NYHA分级和超声心动图LAD、LVEF、LVEDD的相关性,NT-proCNP不能很好地反映心功能和超声心动图指标.

中性粒细胞淋巴细胞比值在评估心功能严重程度中的应用

目的探讨外周血中性粒细胞/淋巴细胞比值(NLR)在评估心力衰竭(心衰)患者心功能严重程度方面的价值。方法收集2014年1月~2015年12月于大连大学附属中山医院心脏中心住院的心衰患者195例,计算NLR并测定血常规、血浆N端脑钠肽前体(NT-proBNP)超声心动图,采用相关性分析方法分析NLR与左室射血分数(LVEF)、NT-proBNP及NYHA心功能分级之间的相关关系。再根据NLR水平将患者分为NLR2.632及NLR2.632两组,分别对两组患者的基本情况及LVEF、NT-proBNP进行比较;根据NYHA心功能分级将患者分为NYHAⅢ级、Ⅳ级两组,分别对两组患者的基本情况及LVEF、NT-proBNP进行比较。结果相关性分析显示,NLR与NT-proBNP(r=0.435,P=0.006)、NYHA(r=0.368,P=0.021)呈正相关关系,而与LVEF水平(r=-0.438,P=0.005)呈负相关关系。随NLR水平升高,心衰患者的NT-proBNP(P=0.007)及NYHA(P=0.013)分级明显升高,而LVEF水平(P=0.095)则无显著差异。随着NYHA分级水平的升高,NLR(P=0.036)、NT-proBNP(P=0.005)逐渐升高,LVEF(P=0.033)则明显下降。结论外周血NLR水平越高,则心衰患者心功能越差。     

心房颤动对不同心功能分级的患者血浆脑钠肽水平的影响

Objective To assess the effect of atrial fibriUation (AF) on plasma levels of NT-proBNP in patients with different cardiac functions. Methods One hundred and ninty-one patients with chronic heart failure (CHF) were divided into two groups: minor CHF group (NYHA Ⅰ/Ⅱ class) and sever CHF group (NYHA Ⅲ/Ⅳ class). In addition,84 patients without HF (non-HF group) were enrolled as control The plas-ma NT-proBNP were assayed and the effect of AF on the NT-proBNP levels was analyzed to determine inde-pendent of NT-proBNP levels in 3 groups. Results Patients with AF in non-HF had higher NT-proBNP levels than those with sinus rhythm (SR) [(2.95 ±0.41) vs (2.21±0.44) ng/L, P < 0.01], and multi-variables regression demonstrated that age, AF and left atrial diameter (LAD) were independent determinants of NT-proBNP levels (P <0.001). NT-proBNP levels in minor CHF were also higher in patients with AF than that in patients with SR [(3.26±0.40) ng/L vs (2.98±0.54) ng/L, P < 0.05] ; AF, LAD, left ventricular end-systolic dimension (LVESD) and left vontric-ular eject fraction (LVEF) were the independent factors of NT-proBNP levels (P < 0.05). However, there was no difference of NT-proBNP levels between patients with AF and patients with SR [(3.59±0.52) ng/L vs (3.56±0.55) ng/L,P =0.73] ; while age and LVEF were in-dependent factors (P < 0.05). In patients with LVEF < 0.40, AF had not significant affect on NT-proBNP lev-els [AF vs SR: (3.70±0.60) ng/L vs (3.46±0.56) ng/L,P >0.10]; however,AF patients with LVEF≥ 0.40, NT-proBNP levels were increased [AF vs SR: (3.08 ±0.57) ng/L vs (2.67±0.73) ng/L, P < 0.001]. Conclusion The effect of AF on plasma NT-proBNP was related with cardiac functions: in AF pa-tients without or with minor cardiac dysfunction (NYHA Ⅰ /Ⅱ class or LVEF≥0.40) ,NT-proBNP increased; in AF patients with sever cardiac dysfunction (NYHA Ⅲ/Ⅳ class or LVEF < 0.40), NT-proBNP had no sig-nificant changes.

Methods One hundred and ninty-one patients with chronic heart failure (CHF) were divided into two groups: minor CHF group (NYHA Ⅰ/Ⅱ class) and sever CHF group (NYHA Ⅲ/Ⅳ class). In addition,84 patients without HF (non-HF group) were enrolled as control The plas-ma NT-proBNP were assayed and the effect of AF on the NT-proBNP levels was analyzed to determine inde-pendent of NT-proBNP levels in 3 groups. Results Patients with AF in non-HF had higher NT-proBNP levels than those with sinus rhythm (SR) [(2.95 ±0.41) vs (2.21±0.44) ng/L, P < 0.01], and multi-variables regression demonstrated that age, AF and left atrial diameter (LAD) were independent determinants of NT-proBNP levels (P <0.001). NT-proBNP levels in minor CHF were also higher in patients with AF than that in patients with SR [(3.26±0.40) ng/L vs (2.98±0.54) ng/L, P < 0.05] ; AF, LAD, left ventricular end-systolic dimension (LVESD) and left vontric-ular eject fraction (LVEF) were the independent factors of NT-proBNP levels (P < 0.05). However, there was no difference of NT-proBNP levels between patients with AF and patients with SR [(3.59±0.52) ng/L vs (3.56±0.55) ng/L,P =0.73] ; while age and LVEF were in-dependent factors (P < 0.05). In patients with LVEF < 0.40, AF had not significant affect on NT-proBNP lev-els [AF vs SR: (3.70±0.60) ng/L vs (3.46±0.56) ng/L,P >0.10]; however,AF patients with LVEF≥ 0.40, NT-proBNP levels were increased [AF vs SR: (3.08 ±0.57) ng/L vs (2.67±0.73) ng/L, P < 0.001]. Conclusion The effect of AF on plasma NT-proBNP was related with cardiac functions: in AF pa-tients without or with minor cardiac dysfunction (NYHA Ⅰ /Ⅱ class or LVEF≥0.40) ,NT-proBNP increased; in AF patients with sever cardiac dysfunction (NYHA Ⅲ/Ⅳ class or LVEF < 0.40), NT-proBNP had no sig-nificant changes.     

心房颤动对不同心功能分级的患者血浆脑钠肽水平的影响

Objective To assess the effect of atrial fibriUation (AF) on plasma levels of NT-proBNP in patients with different cardiac functions. Methods One hundred and ninty-one patients with chronic heart failure (CHF) were divided into two groups: minor CHF group (NYHA Ⅰ/Ⅱ class) and sever CHF group (NYHA Ⅲ/Ⅳ class).
