Previously, we proved that a stressful event as cancer
diagnosis was associated with a poor outcome as suicide . In
the current study, we sought to assess the association
between a stressful event coronary surgery and depression.
Literature review was done and 2 meta-analyses were
identified with particular interest in this topic.
Depression and coronary artery disease are highly comorbid
and often observed harmoniously in patients [2,3]. Thus,
making it imperative to follow the course of depression
postoperatively. Ravven et al. , conducted a meta-analysis
about depressive symptoms after CABG surgery; in which out
of 1883 searched abstracts, 39 studies on depression after
CABG that included 8633 patients were identified (Figure 1).
Risk of depression was increased early (1-2weeks
postoperatively; relative risk [RR]=1.27; 95% confidence
interval [CI], 1.01-1.61). There was a significantly decreased
risk of depression at recovery (>2weeks-2months
postoperatively; RR=0.78; 95% CI, 0.67-0.90), mid
((>2months-6months postoperatively; RR=0.64, 95% CI,
0.58-0.70) and late (>6months postoperatively; RR=0.68; 95%
CI, 0.58-0.79) time points (Table 1).
