Among patients with acute myocardial infarction treated with PCI, 10.8% had unplanned rehospitalizations within 30 days, with baseline quality of life and depression being the strongest predictors.

Early unplanned rehospitalizations are common after AMI, with nearly a third being observation stays, and are strongly associated with baseline quality of life and depression.
BACKGROUND: Previous studies examining early readmission after acute myocardial infarction have focused exclusively on inpatient readmissions. However, from a patient's perspective, any unplanned inpatient or observation rehospitalization after acute myocardial infarction represents a significant event; these unplanned rehospitalizations have not been well characterized. METHODS AND RESULTS: We examined all patients with acute myocardial infarction treated with percutaneous coronary intervention and discharged alive from 233 hospitals in the Treatment With Adenosine Diphosphate Receptor Inhibitors: Longitudinal Assessment of Treatment Patterns and Events After Acute Coronary Syndrome (TRANSLATE-ACS) study from 2010 to 2012. Our primary outcome was unplanned rehospitalizations (inpatient or observation status) within 30 days after discharge. We identified factors associated with unplanned rehospitalizations using multivariable logistic regression. Among 12 312 patients, 1326 (10.8%) had 1483 unplanned rehospitalizations within 30 days of the index event: 1028 (69.3%) were inpatient readmissions, and 455 (30.7%) were observation stays. The majority of unplanned rehospitalizations (72%) were for cardiovascular reasons. Variation in hospital rates of 30-day unplanned rehospitalization ranged from 5.4% to 20.0%, with a median of 10.7%. After multivariable modeling, the factors most strongly associated with unplanned rehospitalization were baseline quality of life and depression, followed by index hospital length of stay. CONCLUSIONS: Early unplanned rehospitalizations are common after acute myocardial infarction, and close to one third were classified as an observation stay. Predischarge and postdischarge assessments of overall, not just cardiovascular, health and strategies to optimize patient functional status may help to reduce unplanned rehospitalizations.

Hess et al. (Mon,) conducted a observational in Acute myocardial infarction (n=12,312). Baseline quality of life, depression, and index hospital length of stay was evaluated on Unplanned rehospitalizations (inpatient or observation status) within 30 days after discharge. Among patients with acute myocardial infarction treated with PCI, 10.8% had unplanned rehospitalizations within 30 days, with baseline quality of life and depression being the strongest predictors.
