To the Editor In their recently published Original Investigation, Garzillo and colleagues¹ presented an interesting 10-year follow-up analysis from the second Medical, Angioplasty, or Surgery Study (MASS II) trial. In the article, the authors present an observational (nonrandomized) comparison assessing the predictive value of stress testing in the study population and report that the presence of ischemia did not identify people at risk of major adverse cardiovascular events at 10 years. We would like to point to a number of caveats that will help in interpreting the findings of this report.

已知症状性多支冠状动脉疾病患者的压力测试和风险预测。

致编辑在最近发表的《原始调查》中，Gazzillo及其同事¹提出了第二项医学，血管成形术或外科手术研究（MASS II）的有趣的10年随访分析。在本文中，作者提出了一项观察性（非随机）比较，评估了压力测试在研究人群中的预测价值，并报告了缺血的存在并未识别出10年内有发生严重不良心血管事件风险的人。我们想指出一些警告，这些将有助于解释本报告的结论。
