脑钠素、白细胞介素-6和白细胞介素-10在慢性心力衰竭危险分层、预后评估中的价值

目的:研究慢性心力衰竭(心衰,CHF)患者左室质量指数(LVMI)、血浆脑钠素(BNP)、白细胞介素-6(IL-6)、白细胞介素-10(IL-10)在CHF危险分层、预后评估中的价值.方法:收集符合2001年ACC/AHA心衰指南中心衰分期标准的95例CHF患者,其中A期21例,B期23例,C期31例,D期20例.抽取同期20例健康查体者作为对照组.测定所有人选者血浆BNP、IL-6和IL-10浓度,并进行组间比较.CHF组每3个月随访1次,随访期2年.因心衰再住院或心血管疾病死亡为终点事件.结果:(1)LVMI异常始见于CHF B期患者,是左窒重构中较早出现的指标.(2)血浆BNP水平升高始见于CHF B期患者,且随病情进展逐渐升高.(3)随心衰进展(C、D期),血浆IL-6、IL-10水平升高,二者比值下降,血浆BNP水平与IL-6、IL-10呈正相关.(4)Stage 分期法能较NYHA分级更好地预测CHF终点事件发生率.(5)COX回归分析提示BNP、IL-6水平为评价CHF预后的危险因素(P＜0.01,P=0.026).(6)将Stage分期与BNP水平结合进行危险分层,高危组终点事件发生率明显增加.结论:(1)LVMI可以早期预示左室重构.(2)心衰进展的内在机制是炎症反应进行性加重.(3)BNP水平是预测有症状心衰发生和预后的良好指标,BNP和Stage分期相结合危险分层方法有助于更好地判断心衰患者预后.

Values of BNP,IL-6 and IL-10 in Stratification and Prognostic for Patients with Congestvie Heart Failure

Objective:To investigate the changes of left ventricular mass index (LVMI),plasma brain natriuretic peptide (BNP),interleukin-6(IL-6) and interleukin-10(IL-10) in patients with congestive heart failure (CHF),and their values in risk stratification and prognostic evaluation of CHF thereof.Methods:Ninety-five patients with CHF in accordance with 2001 ACC/AHA guidelines were enrolled and stratified as stage A(n=21),B(n=23),C(n=31) and D(n=20).The levels of plasma BNP,IL-6 and IL-10 were measured and compaired ...
