Since the authors’ reply to our critical appraisal did not properly address the points we raised, we still see need for further clarification.
The wearable cardioverter defibrillator (WCD) is not an adequate substitute for an implantable cardioverter defibrillator (ICD). The authors state that both can be compared immediately post-myocardial infarction (MI). According to the current guidelines, primary prevention of sudden cardiac death with the ICD within 40 days after MI is generally not indicated.1 Therefore, we disagree with the authors’ proposal of conducting such a trial. In this context, the authors mentioned the VEST trial, which compares a WCD population and one receiving medical treatment. There is explicitly no comparison to an ICD population.
