本项研究确定根据血流储备分数(FFR)≥0.75而延期行冠状动脉血运重建的安全性。研究对象为一组连续、未经筛选的中等程度冠状动脉病变的冠心病患者,包括不稳定型心绞痛、心肌梗死(MI)和(或)无创性检查结果阳性的患者。研究纳入了201例连续的冠心病病例(平均年龄62±10岁,65%为男性);共有231处病变,测定病变的FFR,对FFR≥0.75的病变延期行血运重建。与无创性检查结果阳性相关的病变是指位于支配某一心肌区域的动脉病变,该区域的心肌缺血经无创性检查证实。
This study determined the safety of delaying coronary revascularization based on a blood flow reserve score (FFR) ≥ 0.75. The study population consisted of a series of consecutive, unscreened patients with coronary heart disease of moderate degree of coronary artery disease, including patients with unstable angina, myocardial infarction (MI), and / or noninvasive findings. The study enrolled 201 consecutive patients with coronary heart disease (mean age 62 ± 10 years; 65% men); 231 lesions were included in the study. FFR was measured in the lesion and revascularization was performed in patients with FFR ≥ 0.75. Lesions associated with a positive noninvasive test result are arterial lesions located in a region of the myocardium that has been confirmed by noninvasive examination.
