Alexithymia and Cardiac Outcome in Patients at First Acute Coronary Syndrome
This cohort study was aimed to verify whether subjects at their first acute coronary syndrome (ACS) were more alexithymic than healthy controls (HC) and whether alexithymia can predispose patients with coronary artery disease to new major adverse cardiac events (MACE) during a 24-month follow-up period.
The sample included 100 HC with no history of depression or ACS and 304 never depressed patients with a first-ever ACS. A total of 266 patients completed the 2-year follow-up.
Patients and HC reported similar Toronto Alexithymia Scale (TAS-20) scores. During the follow-up, 69 (22.69%) patients developed incident depression and 57 (18.75%) developed a new MACE. In a proportional hazard model, developing a first-ever depressive episode, but not alexithymia (hazard ratio = 1.008, 95% confidence interval = 0.984–1.033; p = 0.500), was associated with almost 3 times the risk of a recurrent cardiac event.
Incident depression, but not TAS-20 scores, represented risk factor for MACE.
