Perioperative Depression and its Effect on Survival after Coronary Surgery | Insight Medical Publishing

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. [2], 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
