Ossola P, et al. - In patients with their first acute coronary syndrome (ACS), researchers sought to verify the role of personality disorders in incident depression. Participants were 262 patients who were never depressed and were consecutively admitted to the Coronary Intensive Care Unit for a first ACS. The Primary Care Evaluation of Mental Disorders (DSM-IV criteria) was used to assess the presence of depressive disorder; the Hospital Anxiety and Depression Scale was used to assess its severity. They collected evaluations at baseline and at 1, 2, 4, 6, 9, 12 and 24 months of follow-up. Outcomes revealed a depressive disorder diagnosis in 56 patients (21%). Being widowed, having a distress reaction and narcissistic personality traits were identified to be the risk factors for incident depression at baseline.
