Outcomes after readmission at the index or nonindex hospital following acute myocardial infarction complicated by cardiogenic shock.

Over one-fourth of readmissions following AMI-CS were to nonindex hospitals. These admissions were associated with higher hospitalization costs, longer LOS, and higher in-hospital mortality rates. Further studies are needed to evaluate whether a continuity of care plan in the acute hospital setting can improve outcomes after AMI-CS.
