目的探讨急性心肌梗死(AMI)患者入院时肌钙蛋白I(cTnI)水平对无复流发生的预测价值。方法将140例AMI患者根据入院时cTnI水平分为cTnI升高组和cTnI正常组,比较两组直接经皮冠状动脉介入治疗(PCI)后心电图ST段下降幅度(STR%)、梗塞相关动脉(IRA)的TIMI血流级别和校正的TIMI帧数(CTFC)。结果cTnI升高组STR%<30者较cTnI正常组多(25.4%比12.3%,P<0.05),TIMI<3级者亦多(31.3%比13.7%,P<0.05),CTFC≥30祯者亦较多(42.9%比21.7%,P<0.05),两组比较差异有显著性。结论AMI患者入院时cTnI升高者,无复流发生率高,心肌灌注不良。
Objective To investigate the predictive value of troponin I (cTnI) levels in patients with acute myocardial infarction (AMI) on admission without recurrence. Methods One hundred and forty patients with AMI were divided into two groups according to cTnI level at admission: normal cTnI group and normal cTnI group. The ST segment decline (STR%), infarction related artery IRI) TIMI flow levels and corrected TIMI frames (CTFC). Results The percentage of patients with elevated cTnI in the cTnI group was significantly higher than that in the cTnI group (25.4% vs 12.3%, P <0.05), TIMI was less than 3 (31.3% vs. 13.7%, P <0.05) (42.9% vs 21.7%, P <0.05). There was significant difference between the two groups. Conclusions Patients with AMI on admission had elevated cTnI, high incidence of no-reflow, and poor myocardial perfusion.
