随着冠状动脉血运重建术的广泛应用,如何选择适应证以及术后疗效的判断日益引起人们的高度重视,因此,存活心肌的检测,区分心肌损害的可逆性(冬眠心肌、顿抑心肌)和不可逆性(瘢痕组织),对冠状动脉的血运重建术具有决策和预后判断价值。目前,正电子发射断层扫描(PET)被认为是一种评价冠心病患者心肌存活独特、无创而敏感的方法。通过回顾近年来PET显像评价存活心肌的各种方法及对照研究,概述PET对估价存活心肌的价值和最新进展,并对其未来进行初步展望。
With the extensive use of coronary revascularization, how to choose indications and the judgment of postoperative efficacy has drawn increasing attention, therefore, the detection of viable myocardium, the reversibility of myocardial damage (hibernating myocardium, stunned myocardium) And irreversibility (scar tissue), coronary artery revascularization with decision-making and prognostic value. Currently, positron emission tomography (PET) is considered as a unique, noninvasive and sensitive method for assessing myocardial survival in patients with coronary artery disease. By reviewing various methods and control studies of PET imaging in the evaluation of viable myocardium in recent years, this paper summarizes the value and latest progress of PET in evaluating viable myocardium, and makes an initial prospect of its future.
