目的 :探讨急性心肌梗死 (AMI)患者血管再通后心肌组织灌注的评价方法。方法 :AMI患者接受成功的冠状动脉内介入治疗后 ,检查术前及术后 1h心电图ST段回落情况 ,并在术后检测校正的TIMI帧数(CTFC) ,观察两者之间的关系。结果 :根据ST段回落程度将患者分为 3组 ,ST段完全回落组的CTFC较低 ,术后 1个月检查射血分数恢复较好 ;无ST段回落组CTFC较高 ,射血分数值较低 ;ST段部分回落组介于两者之间。结论 :CTFC是目前临床上较理想的评价心肌微血管灌注的指标之一 ,它联合心电图ST段回落可更好地预测AMI患者的危险度 ,为是否需要进一步治疗提供可靠的依据
Objective: To evaluate the evaluation of myocardial perfusion after revascularization in patients with acute myocardial infarction (AMI). Methods: After successful intracoronary interventional therapy in AMI patients, the fall of ST segment in preoperative and postoperative 1h electrocardiogram was examined. The corrected TIMI frames (CTFC) were detected after operation to observe the relationship between them. Results: The patients were divided into three groups according to the degree of ST segment regression. The CTFC of ST-segment depression group was lower and the ejection fraction was better at 1 month after surgery. The CTFC of ST-segment depression group was higher and the ejection fraction Lower; ST-segment part of the fall group in between the two. Conclusion: CTFC is one of the most ideal indicators to evaluate myocardial microvascular perfusion at present. Combined with ECG ST-segment depression, CTFC can better predict the risk of AMI and provide a reliable basis for further treatment.
