一个独立开发的和以前验证的QRS评分系统估计心肌梗死面积已被用于比较的发展和回归的变化与心肌梗死发生在2个不同的临床设置。众所周知，QRS变化提示冠状动脉旁路移植术后发生心肌梗死。本研究比较了40例非手术急性心肌梗死患者与46例非手术急性心肌梗死患者的QRS变化的幅度和时间过程。两组中只有基线心电图（ECG）无既往心肌梗死、心室肥大或束支分支传导阻滞证据的患者纳入研究。两组在急性期达到相似的QRS峰值评分，但观察到评分的缓解率不同。在随后的2个月中，围手术期组的QRS变化的消退比对照组更快（43%对19%）。在剩余的随访期间，两组的消退率相似，到18个月时，手术组和非手术组的总下降率分别为62%和37%。这些结果可能意味着急性梗死以外的因素是围手术期QRS变化的原因，或者两种临床环境中的梗死愈合过程完全不同。
An independently developed and previously validated QRS scoring system for estimating myocardial infarct size has been used to compare the development and regression of changes associated with myocardial infarcts occurring in 2 different clinical settings. It is known that QRS changes suggesting myocardial infarction occur after coronary artery bypass grafting. This study compares the magnitudes and time courses of these QRS changes in 40 patients with the QRS changes observed in a control group of 46 patients with nonoperative acute myocardial infarcts. Only patients in both groups who had a baseline electrocardiogram (ECG) with no evidence of previous myocardial infarcts, ventricular hypertrophy, or bundle branch block were included. Both groups attained similar peak QRS scores during the acute phase but different rates of resolution of scores were observed. During the subsequent 2 months, regression of QRS changes occurred more rapidly in the perioperative group than in the control group (43 versus 19%). Rates of regression were similar in both groups during the remainder of the follow-up period, attaining total decreases of 62% in the operative group and 37% in the nonoperative group by 18 months. These results could mean either that factors other than acute infarction are responsible for the perioperative QRS changes or that the infarct healing process in the 2 clinical settings are quite different.
