To the Editor We read with great interest the Review article by Stewart and Fong.¹ We completely agree with the concluding remarks that there is a critical need for additional research on the effects of perioperative cannabis. However, we have some concerns.

The authors state after citing very early publications that there is “…no demonstrable association between cannabis use and myocardial infarction.”¹ However, multiple case reports over the past years have linked cannabis to acute myocardial infarction. A recent publication examined whether patients with chronic cannabis use have an elevated risk of postoperative complications.² This large nationwide patient sample study demonstrated that chronic cannabis consumption is associated with a meaningful increase in the risk of postoperative myocardial infarction.²

致编辑我们非常感兴趣地阅读了 Stewart 和 Fong 的评论文章。¹我们完全同意结论性意见，即迫切需要对围手术期大麻的影响进行进一步研究。但是，我们有一些担忧。

作者在引用非常早期的出版物后指出，“……大麻使用与心肌梗塞之间没有明显的关联。” ¹然而，过去几年的多起病例报告将大麻与急性心肌梗塞联系起来。最近的一份出版物检查了长期使用大麻的患者术后并发症的风险是否升高。²这项全国性的大型患者样本研究表明，慢性大麻消费与术后心肌梗塞风险的显着增加有关。²
