摘 要:目的 探讨老年冠心病患者脑利钠肽和纤维蛋白原的相关性。方法选择325例年龄65岁及以上老年冠心病患者,根据脑利钠肽(BNP)数值的四分位数(P25为32.4ng/L、P50为62.3ng/L、P,5为162.5ng/L)将所有患者分为4组,BNP≤32.4ng/L组,32.5~62.3ng/L组、62.4ng/L~162.5ng/L组、BNP〉162.5ng/L组。比较各组左心室射血分数、左心室舒张末径及纤维蛋白原(Fib)水平。结果随着BNP水平的升高,患者左心室射血分数逐渐下降,≤32.4ng/L组,32.5~62.3ng/L组、62.4ng/L~162.5ng/L组、BNP〉162.5ng/L组分别为(63.3±8.2)%、(59.6±7.4)%、(57.9±9.7)%、(55.2±10.6)%;左心室舒张末径逐渐增大,分别为(50.5±4.7)mm、(51.4±5.4)mm、(52.8±5.7)mm、(54.2土5.9)mm,差异有统计学意义(F=11.54,F=6.76,均P〈0.01);Fib水平逐渐升高,分别为(3.4±0.7)g/L、(3.7±0.8)g/L、(3.8±1.1)g/L、(4.2±1.0)g/L,差异有统计学意义(F=8.02,P<0.01)。BNP与Fib呈正相关(r=0.25,P〈0.01)。多元线性回归分析结果表明,Fib和左心室射血分数是BNP的影响因素(t=2.92,t=-3.15,均P〈0.01)。结论BNP可作为心力衰竭的诊断和判断其严重程度的敏感指标。当患者心功能恶化时,血液处于高凝、高黏状态,Fib水平亦随之升高。BNP与Fib相关。Objective To explore the relationship between B-type natriuretic peptide (BNP) and fibrinogen (Fib) in the elderly patients with coronary heart disease (CHD). Methods According to the level of BNP, 325 subjects aged more than 65 years were divided into four groups, BNP:≤32.4 ng/L group,32.5-62.3 ng/L group, 62.4-162.5 ng/L group, 〉162.5 ng/L group. The levels of left ventricular ejection fraction (LVEF), left ventrieular end-diastole dimension (LVEDD) and Fib were compared among the groups. Results With increasing BNP level, the LVEF was gradually decreased ((63.34±8.2)% (59.6±7.4)% , (57.9±9.7)%, (55.2±10.6)% and the level of LVEDD was increased[(50.5±4.7)mm, (51.4±5.4)mm, (52.8±5.7)mm, (54.2±5.9)mm F= 11.54, 6.76, both P(0.01], the level of Fib was enhanced [(3.4±0.7)g/L, (3.7±0.8)g/L, (3.8±1. 1)g/L, (4.2±1.0)g/L F=8.02,P(0. 013. The level of BNP had positive correlation with Fib (r=0.25, P〈(0.01). Multi-linear regression analysis showed that Fib and LVEF were influencing factors of BNP (t =2.92, -3. 15, both P 〈 0.01 ) . Conclusions The BNP level is helpful to diagnose heart failure and assess heart function. There is an association between BNP and Fib level.
