Abstract
OBJECTIVE: To examine the effects of depressive symptoms and Endothelin (ET)-1 on 2-year prognosis in younger patients with acute coronary syndrome (ACS). Depression is associated with poor post-ACS prognosis; however, few investigations have focused on younger patients. Importantly, the studies that did emphasize younger patients suggested that the influence of depression on prognosis could be more robust in younger subgroups. The particular links between depression and poor prognosis in younger patients have yet to be definitively determined. ET-1 is a potent endogenous vasoconstrictor that has been previously linked to adverse post-ACS outcomes. METHODS: The sample (n=153) included male (age≤50years) and female (age≤55years) ACS patients. Blood samples for ET-1 assessment were collected within 2-3h of ACS hospital admission. Depressive symptoms were assessed with the Beck Depression Inventory (BDI) II within 2-5days of admission. The primary outcome was defined as a composite of major adverse cardiovascular events (MACE), including recurrent myocardial infarction, emergent coronary revascularization, and all-cause mortality within 2years after index admission. RESULTS: During the follow-up period, 23 patients experienced MACE. Neither the BDI-II score nor ET-1 predicted MACE in unadjusted analyses or in analyses adjusted for demographic characteristics, comorbidities and troponin levels. In the supplementary analyses, feeling depressed in the year preceding ACS predicted MACE. CONCLUSIONS: In this cohort of younger ACS patients, feeling depressed in the year preceding ACS admission predicted MACE in the 2years after baseline ACS event, while neither the BDI-II score, nor circulating ET-1 level predicted this outcome.
