【摘要】：目的分析血流儲備分?jǐn)?shù)(FFR)與急性心肌梗死(AMI)延遲經(jīng)皮冠狀動脈介入治療(PCI)效果的關(guān)系。方法選擇42例行延遲PCI治療的AMI患者,PCI前行FFR檢查;PCI前及PCI后1周行靜息99mTc-MIBI心肌灌注顯像,計算心肌灌注顯像缺損積分;于PCI前及PCI后12個月行常規(guī)超聲心動圖檢查,測量左心室射血分?jǐn)?shù)(LVEF)及左心室舒張末期內(nèi)徑(LVEDD)。結(jié)果 FFR0.75者22例、≥0.75者20例,二者年齡、性別、心血管病危險因素、冠狀動脈病變支數(shù)及支架置入情況差異無統(tǒng)計學(xué)意義。FFR0.75者PCI后靜息心肌灌注顯像缺損積分較PCI前降低(P0.05),FFR≥0.75者PCI前后變化不明顯(P0.05)。PCI前FFR0.75者與FFR≥0.75者比較,LVEF增加、LVEDD減小(P均0.05);PCI后FFR0.75者較PCI前及FFR≥0.75者PCI后LVEF增加、LVEDD減小(P均0.05),而FFR≥0.75者僅LVEF較PCI前增加(P0.05)。結(jié)論 FFR0.75的AMI患者行延遲PCI療效較好,FFR檢查有助于AMI患者延遲PCI療效的判斷。
[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，
