目的 探讨N末端原脑钠肽(NT-proBNP)水平对早期急性冠状动脉综合征(ACS)患者远期预后的预测价值.方法 ACS患者164例,测定入院首次(＜12 h)血NT-proBNP水平,以NT-proBNP水平75%分位及以下为基线水平(低值组123例)与75%分位以上(高值组41例)的心血管不良事件进行1个月、6个月和≥12个月随访和比较分析.结果 高值组与低值组比较,1个月、6个月和≥12个月死亡的危险度(OR)分别为4.1、5.6和4.0,高值组非致死性心力衰竭为4例、4例和7例,而低值组分别为0、1例和1例,多因素Logistic回归分析结果表明,NT-proBNP仍为ACS患者近期、中期和远期不良事件的独立危险因素(P＜0.05).结论 NT-proBNP是早期急性ACS远期心血管不良事件的预测因子.

Abstract：

Objective To explore the long-term predictive value of serum concentration of N-terminal prosoma brain natriuretic peptide (NT-proBNP) in the early acute coronary syndrome (ACS). Methods The 164 patients firstly hospitalized and finally diagnosed as acute myocardial infarction (AMI) were selected, and then the serum concentration of NT-proBNP was determined in less than 12 hours. According to the 75 percentage points of serum concentration of NT-proBNP, the patients were divided into two groups: low concentration group (n = 123) and high concentration group (n = 41 ). The major adverse cardiac events (MACEs) were followed and compared at one month, six months and twelve months between low group and high group. Results At 1-, 6-, 12-month follow-up, the odds ratio (OR) of death event were 4.1, 5.6 and 4.0 in high group respectively, and the nonfatal heart failure occurred in 4, 4 and 7 patients in high group. Multiple factor logistic regression analysis showed that NT-proBNP was an independent risk factor of the MACEs at different periods including short time, middle time and long time in ACS patients (P＜0. 05). Conclusions NT-proBNP is a strong predictor of the long-term MACEs in patients with early ACS.

脑钠肽在慢性心力衰竭诊断与预后中的作用

随着人口老龄化进程的加快,高血压、冠心病等常见心血管病发病率在上升,慢性心力衰竭(congestive heart failure,CHF)的发病逐渐增多.20世纪90年代以来,虽然人们对CHF的研究取得了更深入进展,对CHF发生发展机制的认识有了很大进步,使治疗决策也有很大进展.但是,CHF在临床诊断、预后和危险分层方面仍然存在着许多困惑,给急诊治疗带来了困难.最近国外研究显示,CHF患者血浆中脑钠肽(B-type natriuretic peptide,BNP)水平明显增高,是CHF诊断和预后的重要指标[1～3].我们对BNP在CHF诊断与预后中的作用进行综述.

B型利钠肽对非心源性危重患者的预后价值

Objective B-type natriuretic peptide(BNP) have been used widely in the diagnosis and prognosis of cardiogenic diseases, but the association between BNP concentrations and non-cardiogenic critical illness is unknown. Our study aims at investigating the role of natriuretic peptide testing for predicting 28-day mortality of non-cardiogenic critically ill patients in emergency department (ED). Methods A total of 255 non-cardiogenic critically ill patients treated in the emergency department were prospectively enrolled and a sample of blood was obtained for BNP measurement from each patient. A variety of clinical and laboratory variables were recorded. After 28 days, the vital status of each patient was ascertained and the association between BNP values at presentation and mortality was assessed. Results 71 patients died during the 28-day observation period. Median BNP concentrations at presentation among decedents were significantly higher than those of survivors (326. 0 ng/L versus 50. 9 ng/L,P <0. 001). The optimal BNP cut point for predicting 28-day mortality was 114. 0 ng/L. In a multivariate analysis (Cox-regression), a BNP concentration greater than 114. 0 ng/L(RR 7. 268, 95% CI 3. 864-13. 672) and an Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) scores greater than 20 (RR 3. 330, 95% CI 1. 815-6. 109)were the independent predictors of the 28-day mortality. BNP concentration alone had an area under the receiver operating characteristic curve (AUC) of 0. 825 for predicting mortality. Conclusions BNP concentrations at presentation are strong predictor of 28-day mortality in patients with non-cardiogenic critically ill patients in ED, which is better than Rapid Acute Physiology Score (RAPS) , Rapid Emergency Medicine Score (REMS) and APACHE Ⅱ score.
