摘要
目的:探讨心肌肌钙蛋白T(cTnT)在心肌炎中的动态变化及其与心功能的相关性。方法:对2007年7月~2012年7月入住我院的28例心肌炎(心肌炎组)、24例疑似心肌炎(疑似心肌炎组)以及32例健康体检者(健康对照组),检测各组cTnT、肌酸激酶(CK)、肌酸激酶同工酶(CK-MB)水平,且对cTnT与心功能相关性进行分析。结果:(1)心肌炎组cTnT浓度明显高于疑似心肌炎组与健康对照组[(0.37±0.13)ng/ml比(0.19±0.07)ng/ml、(0.17±0.05)ng/ml),P<0.01];(2)cTnT与心脏指数(CI)、左室射血分数(LVEF)、肺动脉血流加速时间(AT)、相对室壁厚度(RWT)均呈负相关性(r=-0.723~-0.441,P<0.05或<0.01),与左室质量指数(LVMI)、左室舒张末期内径(LVEDd)、左室内径(LAD)、室间隔厚度(IVST)及左室后壁厚度(LVPWT)均呈正相关性(r=0.387~0.763,P均<0.05)。结论:心肌肌钙蛋白T水平是评价心肌炎心功能的一个重要指标。
LI Xiao-li//Department of Pediatrics,Central Hospital of Ankang City,Ankang,Shaanxi,725000,China Objective:To explore dynamic changes of cardiac troponin T(cTnT)in myocarditis and its correlation with cardiac function.Methods:A total of 28patients with myocarditis(myocarditis group),24patients suspected myocarditis(suspected myocarditis group)and 32healthy subjects(healthy control group)admitted in our hospital from Jul 2007to Jul 2012were enrolled.Levels of cTnT,creatine kinase(CK)and CK-MB were measured in three groups,and correlation among cTnT and indexes of cardiac function were analyzed simultaneously.Results:(1) Compared with suspected myocarditis group and healthy control group,there was significant increase in cTnT concentration[(0.19±0.07)ng/ml,(0.17±0.05)ng/ml vs.(0.37±0.13)ng/ml]in myocarditis group,P〈0.01;(2)cTnT was negatively correlated with cardiac index(CI),left ventricular ejection fraction(LVEF),pulmonary artery blood flow acceleration time(AT)and relative wall thickness(RWT),r=-0.723~-0.441,P〈0.05or 0.01;and cTnT was positively correlated with left ventricular mass index(LVMI),left ventricular end-diastolic dimension(LVEDd),left atrial diameter(LAD),interventricular septal thickness(IVST)and left ventricular posterior wall thickness(LVPWT),r=0.387~0.763,P〈0.05all.Conclusion:Cardiac troponin T level is an important index evaluating cardiac function in patients with myocarditis.
