冠脉血流储备分数可能成为非梗死相关血管介入治疗的新标准

FFR could become the new criteria for non-infarct related artery(non-IRA) interventional therapy

既往的研究发现急性ST段抬高型心肌梗死(STEMI)患者合并多支血管病变(MVD)概率可高达40%,是心肌梗死患者预后不良的主要原因之一。目前非梗死相关动脉的治疗策略存在诸多争议,且指南针对STEMI非梗死相关病变的处理无统一意见。冠脉血流储备分数(FFR)较单纯冠脉造影能更直观地评价冠脉血流储备能力,可能成为非梗死相关动脉介入治疗的标准之一。

Previous studies have found that 40% of patients with acute ST-segment elevation myocardial infarction (STEMI) combine with multiple vascular lesions (MVD), which is known as one of the main risks for poor prognosis in patients with myocardial infarction. However;the management of non-IRA remains controversial, and there is no consensus on the management of non-IRA in STEMI. FFR could be a new criteria in non-IRA PCI,since it could evaluate coronary flow reserve more intuitively than coronary angiography alone.
