• Acute myocardial infarction;
  • delirium;
  • predictors

PURPOSE.  To examine the incidence, clinical profile, and predictors of delirium following acute myocardial infarction (MI).

DESIGN AND METHODS.  The study sample included 212 consecutive patients with acute MI who were admitted to the coronary intensive care unit of a university hospital.

FINDINGS.  Delirium was found to occur in 5.7% of the patients. The predictors of delirium were advanced age, higher level of serum potassium at admission, and experience of cardiac arrest during MI.

PRACTICE IMPLICATIONS.  Delirium is reasonably prevalent in patients with acute MI. We propose that patients with the risk factors that have been delineated in this study should be evaluated carefully.
