The angiograms of 89 patients were reviewed from the LATE Ancillary Study (randomized trial of recombinant tissue plasminogen activator vs placebo in patients with symptom onset after 6 hours of myocardial infarction) to determine patency of the infarct-related artery (IRA). In the occluded IRA group (n = 35), the incidence of signal-averaged electrocardiographic abnormality (fQRS > 120 ms) was significantly higher (p = 0.04), the filtered QRS duration was significantly longer (p = 0.007), and the V40 was significantly shorter (p = 0.02), compared with the patent IRA group (n = 54).
回顾了来自LATE辅助研究（心肌梗死6小时后症状发作患者重组组织型纤溶酶原激活剂与安慰剂的随机试验）的89例患者的血管造影片，以确定梗死相关动脉（IRA）的通畅情况。与IRA通畅组（n = 54）相比，在IRA闭塞组（n = 35）中，信号平均心电图异常（fQRS> 120 ms）的发生率显著更高（p = 0.04），滤波后的QRS时限显著更长（p = 0.007），且V40显著更短（p = 0.02）。
