Boldvalues are statistically significant.

CPK = creatinine phosphokinase MB; LVEF = left ventricular ejection fraction; MI = myocardial infarction.

  • The corresponding patient numbers for these assessments were: no post-MI depression (n = 301), incident post-MI depression (n = 59), non-incident depression (n = 46).
