摘要
目的探讨s ST2水平对急性心力衰竭(AHF)患者病情严重程度及预后质量的临床价值。方法选取2014年6月~2015年12月徐州市中心医院心内科收治的AHF患者162例,并收集58例体检健康人为对照,所有患者随访1年,记录患者终点事件发生率。采用ELISA对患者入院时的外周血内s ST2水平进行测定;全自动生化仪检测NT-pro BNP、肌钙蛋白I(TNI)水平;采用ROC曲线分析s ST2评估AHF预后的价值。结果 AHF组患者的s ST2、NT-pro BNP、TNI水平均明显高于正常组体检人员,差异有统计学意义(P<0.05);重度AHF组患者的s ST2、NT-pro BNP、TNI水平均明显高于轻度AHF组患者,差异有统计学意义(P<0.05);随访期间,162例AHF患者中有63例患者发生终点事件,发生率为38.89%,发生终点事件组患者的s ST2水平明显高于未发生终点事件组患者,差异有统计学意义(P<0.05);Logistic多因素回归分析结果显示:s ST2、NT-pro BNP、心功能分级3个协变量对AHF患者预后有独立预测意义(OR=4.003、3.741、7.862);s ST2对AHF患者预后判断的ROC曲线下面积(AUC=0.820)略高于NT-pro BNP(AUC=0.769),差异无统计学意义(P>0.05),二者联合应用预测效果明显提高(AUC=0.938)。结论外周血内s ST2水平可评价AHF患者病情严重程度及预后,如果结合NT-pro BNP等相关生物学标志物,s ST2可以更好地进行危险分层及预后评估。
Objective To discuss the clinical value of peripheral blood sST2 on risk stratification and prognosis in patients with acute heart failure （AHF）. Methods From June 2014 to December 2015, in Xuzhou Central Hospital, 162 AHF patients were selected, 58 healthy persons were chosen as control group. All patients were followed-up 1 year after AHF attack. The incidence of end point was recorded. The sST2 levels were determined by ELISA and the levelsof NT-proBNP and TNI were detected by automatic biochemical analyzer. The value of them on prognosis were analyzed by ROC curve. Results The levels of sST2, NT-proBNP and TNI in AHF patients were significantly higher than healthy people, the differences were statistically significant （P 〈 0.05）. The levels of sST2, NT-proBNP and TNI in mild AHF patients were significantly higher than severe AHF patients, the differences were statistically significant （P 〈 0.05）; 63 patients occurred recurrence of heart failure or cardiac death, and the incidence of the end of observation was 38.89%, the sST2 level in AHF patients with the end of observation was significantly higher than AHF patients without the end of observation, the differences were statistically significant （P 〈 0.05）. The results of Logistic multifactor regression analysis showed thatthe levels of sST2, NT-proBNP and clinical heart function grade had independent predicting value of AHF （OR = 4.003, 3.741, 7.862）. The area under the ROC curve on prognosis of sST2 （AUC = 0.820） was slightly higher than NT-proBNP （AUC = 0.769）, but the difference was not statistically significant （P 〉 0.05）. The prognosis value combined sST2 with NT-proBNP was significantly increased （AUC = 0.938）. Conclusion The level of peripheral blood sST2 may be used toevaluaterisk stratification and prognosis in patients with AHF. It will be better to evaluatethe prognosis combining sST2 with other biomarkers such as NT-proBNP.
