摘要
目的:评估老年冠心病患者超敏肌钙蛋白T(hs-TnT)轻度升高的临床意义,并探讨其可能机制。方法:入选年龄>70岁患者250例,均留取入院次日晨起空腹静脉血,住院期间完成冠状动脉造影,并明确诊断为冠心病;依据hs-TnT值分为轻度升高组(0.014~0.100μg/L)和正常组(<0.014μg/L)。结果:2组患者冠状动脉病变严重程度、左室重量指数[(90.0±26.1)g/m2∶(100.0±30.9)g/m2]、左室收缩功能[(56.0±6.7)%∶(50.0±7.9)%]、估测肾小球滤过率{[(66(74~52)]ml/(min.1.73m2)∶[60(70~49)]ml/(min.1.73m2)}比较均差异有统计学意义(均P<0.05);2组炎症反应指标、左室舒张功能差异无统计学意义。结论:hs-TnT轻度升高与老年冠心病患者冠状动脉病变严重程度、左室重量指数增加、左室收缩功能下降、肾功能减退相关,可作为老年冠心病早期危险分层的一个指标并能指导临床治疗。
Objective:To assess the low level high sensitive troponin T(hs-TnT) in patients with elderly coronary heart dieases,and detect the pathophysiological mechanisms. Method:Two hundred and fifty patients over 70 years old with coronary heart disease were selected.All patients were completed coronary angiography during hospital stays,then divided into normal group(〈0.014 μg/L) and low level elevated group(0.014~0.100 μg/L) according hs-TnT level. Result:There were significant differences in the severity of coronary artery disease,left ventricular mass index,left ventricular systolic function,estimated glomerular filtration rate between 2 groups,while no difference in inflammatory response index and left ventricular diastolic function. Conclusion:Low level elevation of hs-TnT associated with the severity of coronary artery disease,left-ventricula mass index,impaired left-ventricular systolic function and impaired renal function.Hs-TnT may be a clinical indicator for high cardiovascular risk in patients with elderly coronary heart disease.
