Key result
Anxiety-depressive disorders in patients with acute coronary syndrome were associated with a higher rate of cardiovascular complications at 12 months compared to those without.
Why the study?
Anxiety-depressive disorders are a risk factor for cardiovascular mortality in CAD, and altered platelet metabolism may contribute to cardiovascular complications in ACS patients with concomitant anxiety-depressive disorders.
Does the presence of anxiety-depressive disorders and altered platelet metabolism predict cardiovascular complications in patients with acute coronary syndrome?
Cohort (n=315)
Does the presence of anxiety-depressive disorders and altered platelet metabolism predict cardiovascular complications in patients with acute coronary syndrome?
In patients with acute coronary syndrome, concomitant anxiety-depressive disorders are associated with impaired platelet energy metabolism and a higher incidence of cardiovascular complications at 1 year.

Anxiety-depressive disorders (ADD) are a risk factor of cardiovascular mortality in patients with coronary artery disease (CAD). Acute coronary syndrome (ACS) is the main clinical manifestation of a progressing CAD. Metabolic processes disorder in platelets can be one of the causes of cardiovascular complications in patients with ACS and concomitant ADD. We studied platelets metabolism and prognostic informativity of NAD(P)-dependent dehydrogenases of platelets in ACS patients with ADD in terms of forecasting cardiovascular complications development over a year of observation. The levels of NAD- and NADP-dependent dehydrogenases of platelets were determined by means of a bioluminescent method during the first 24 h after admission to hospital and in dynamics in 10 days. Among 315 examined patients, ADD was found in 161 (51.1%). ACS patients with concomitant ADD had both cytoplasmic and mitochondrial processes impairment in platelets that consisted in a decrease of energy metabolism intensity, inhibition of anaerobic glycolysis reactions and lipid catabolism. After 12 months of follow-up, 41 (25.5%) cardiovascular complications were detected in the group of ACS patients with ADD and 20 (13.0%) in the group of ACS patients without ADD. According to the results of the analysis of the neural network based on NAD(P)-dependent dehydrogenases of platelets activity in ACS patients with ADD, indicators were obtained that are informative for predicting the development of recurrent cardiovascular complications.

Shimokhina et al. (2020) conducted a cohort in Acute coronary syndrome (n=315). Anxiety-depressive disorders vs. No anxiety-depressive disorders was evaluated on Cardiovascular complications. Anxiety-depressive disorders in patients with acute coronary syndrome were associated with a higher rate of cardiovascular complications at 12 months compared to those without.
