摘要
目的探讨心肌肌钙蛋白T(cTnT)在不稳定型心绞痛患者冠状动脉病变程度及短期预后中的应用价值。方法以济宁市第二人民医院收治的43例不稳定型心绞痛患者为研究对象,对其住院期间心电图、冠状动脉造影和心肌肌钙蛋白T检查结果进行比较分析,探讨心肌肌钙蛋白T的临床应用价值。结果心电图ST-T改变患者cTnT为(0.24±0.1)ng/ml,明显高于心电图ST-T未改变者(P<0.05);冠状动脉造影(CAG)提示重度狭窄与完全狭窄患者的cTnT同轻度狭窄、重度狭窄和正常者比较,差异有统计学意义(P<0.05);cTnT<0.2ng/ml患者的短期预后好于cTnT>0.2ng/ml,两组CAG狭窄程度比较差异有统计学意义(P<0.05)。结论心肌肌钙蛋白T对不稳定型心绞痛患者冠状动脉病变程度有一定的评估价值,其对短期预后的指导意义重大。
Objective To study the application value of myocardial troponin T in the severity of coronary artery disease and prognosis of unstable angina patients. Methods Forty-ttu＇ee patients with unstable angina pectoris in the second people＇ s hospital of Jining were regarded as the research objects. The hospitalization ECG, coronary angiography and cardiac troponin T of the patients were compared and analyzed. The clinical value of cardiac troponin T was discussed. Results cTnT of patients with the ECG ST-T change was （0. 24 ±0. 1 ） ng/ml, which was significantly higher than that without ECG ST-T changes （P 〈0. 05）. CAG indicated that severe cTnT of stenosis and complete stenosis patients had significant difference with mild stenosis, severe stenosis and normal （ P 〈 0. 05 ）. The short term prognosis of patients with cTNT 〈 0. 2 ng/ml was better than that of cTNT 〉 0. 2 ng/ml. CAG stenosis degree of the two groups also had significant difference （P 〈 0. 05）. Conclusion Cardiac troponin T has certain assessment value for the severity of coronary artery disease of unstable angina peetoris, and has great guiding value for short-term prognosis.
