To the Editor We read with great interest the article written by Patel et al1 in JAMA Cardiology detailing trends and outcomes on coronary angioplasty and percutaneous coronary intervention after out-of-hospital cardiac arrest (OHCA) with ventricular fibrillation (VF) or pulseless ventricular tachycardia. While the results and conclusions of this article are encouraging, we do have concerns about the methods used.
