肌钙蛋白T和脑钠肽水平对非ST段抬高型心肌梗死诊断及预后的临床意义

目的 探讨肌钙蛋白T和脑钠肽水平对非ST段抬高型心肌梗死早期诊断和预后的价值. 方法 以急性非ST段抬高型心肌梗死病人60例及体检健康者50例为研究对象,对血清肌钙蛋白T(cTnT)和脑钠肽(BNP)水平的变化作相关性比较分析. 结果 实验组血清cTnT和血清BNP水平明显高于正常对照组(P＜0.01),同时实验组中BNP高峰特续时间明显长于cTnT(P ＜0.01),且BNP高峰持续时间长者发生心衰的危险性明显增高(P＜0.01). 结论 血清cTnT与BNP水平对于非ST段抬高型心肌梗死的早期诊断无明显差别,BNP在预后方面有明显的参考价值.

Observation of cTnT and BNP level in the Diagnosis and Prognosis of NSTEMI

ObjectiveTo study the benefits about cTnT and BNP in early diagnosis and prognosis for non-ST elevated myocardiac infarction(NSTEMI).MethodsTo collect patients with acute NSTEMI and healthy volunteers as study objects,dynamically monitor serum cTnT and BNP and compare their relationship.ResultsThe level of serum cTnT and BNP in study group was significantly higher than the control group (P<0.01),and the peak of BNP lasted significantly longer than cTnT(P<0.01),and there was significant relationship between high BNP and the incidence of heart failure (P<0.01).ConclusionsThere are no differences between cTnT and BNP in early diagnosis about NSTEMI,but BNP is important to the prognosis of myocardial infarction.
