Patients with acute coronary syndrome generally exhibit higher depression scores than controls, though those experiencing AMI with ventricular fibrillation paradoxically show lower depression scores which may correlate with a better prognosis.

Depression screening in ACS warrants arrhythmia subtype nuance; leaves open prognostic implications of lower scores in AMI-VF.
This study examined the prevalence of depression based on scores of 200 patients with acute coronary syndrome on the Emotion Profile Index of Plutchik and its relationship with the type of acute coronary syndrome and the severity of ischemic heart disease. Patients with acute coronary syndrome scored higher on depression than the control group. There was no difference in scores on Depression by type of acute coronary syndrome and no significant mean differences on Depression for patients with and without left ventricular failure. Patients with acute myocardial infarction and ventricular fibrillation scored lower on Depression than other patients with acute myocardial infarction and control group. This study supports the view that patients with acute myocardial infarction and ventricular fibrillation and lower scores on Depression have good prognosis during hospitalization and maybe for the long term.
