【摘要】：目的分析血流储备分数(FFR)与急性心肌梗死(AMI)延迟经皮冠状动脉介入治疗(PCI)效果的关系。方法选择42例行延迟PCI治疗的AMI患者,PCI前行FFR检查;PCI前及PCI后1周行静息99mTc-MIBI心肌灌注显像,计算心肌灌注显像缺损积分;于PCI前及PCI后12个月行常规超声心动图检查,测量左心室射血分数(LVEF)及左心室舒张末期内径(LVEDD)。结果 FFR0.75者22例、≥0.75者20例,二者年龄、性别、心血管病危险因素、冠状动脉病变支数及支架置入情况差异无统计学意义。FFR0.75者PCI后静息心肌灌注显像缺损积分较PCI前降低(P0.05),FFR≥0.75者PCI前后变化不明显(P0.05)。PCI前FFR0.75者与FFR≥0.75者比较,LVEF增加、LVEDD减小(P均0.05);PCI后FFR0.75者较PCI前及FFR≥0.75者PCI后LVEF增加、LVEDD减小(P均0.05),而FFR≥0.75者仅LVEF较PCI前增加(P0.05)。结论 FFR0.75的AMI患者行延迟PCI疗效较好,FFR检查有助于AMI患者延迟PCI疗效的判断。
[Abstract]:Objective to analyze the relationship between the blood flow reserve fraction (FFR) and the effect of delayed percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI). Methods 42 patients with AMI undergoing delayed PCI were studied before FFR and 1 week after PCI. 99mTc-MIBI myocardial perfusion imaging, The defect score of myocardial perfusion imaging was calculated, the left ventricular ejection fraction (LVEF) and left ventricular end-diastolic diameter (LVEDDV) were measured before PCI and 12 months after PCI. Cardiovascular risk factors, There was no significant difference in the number of coronary artery diseased branches and stent implantation. The defect score of resting myocardial perfusion imaging after PCI in patients with FFR 0.75 was lower than that before PCI. There was no significant change before and after PCI in patients with FFR0.75 and FFR 鈮，
