Abstract
BACKGROUND: Whether depressive disorders predict rehospitalization after AMI is unknown. METHODS AND RESULTS: <0.001; major depression adjusted hazard ratio, 2.54; 95% CI, 1.84-3.53; P<0.001), had more hospitalizations (minor, P<0.001; major, P<0.001) and emergency department visits (minor, P=0.003; major, P<0.001), and spent more days in the hospital (minor, P<0.001; major, P<0.001). The interview and questionnaire methods of assessing depression did not significantly differ in their overall accuracy of predicting rehospitalization.ConclusionsDepressive disorders increase the risk of rehospitalization after AMI. Future work should focus on developing multivariable models to predict risk of rehospitalization after AMI, and depression should be included in these.
