Acute cardiac care & resuscitation
Short- and long-term outcomes of patients with acute myocardial infarction complicated by cardiac arrest: a nationwide cohort study 2013–22
Authors' conclusion
In this large, contemporary cohort of AMI patients, in-hospital mortality of patients with OHCA or IHCA was still high. Among patients surviving to hospital discharge, long-term mortality was comparable between OHCA and AMI without CA, while the outcome of patients with IHCA was significantly worse.
