Cilostazol for Major Depressive Disorder After Percutaneous Coronary Intervention or Coronary Artery Bypass Grafting: A Randomized, Double-Blind, Placebo-Controlled Trial
Abstract
Background: Major depressive disorder (MDD) frequently occurs alongside coronary artery disease (CAD), worsening cardiovascular outcomes. Cilostazol is a phosphodiesterase 3 inhibitor used as an antiplatelet agent with potential antidepressant effects. This study evaluated the efficacy of cilostazol for treating depressive symptoms in participants with CAD.
Methods: This 6-week, double-blind, placebo-controlled clinical trial enrolled individuals with MDD and Hamilton Depression Rating Scale (HDRS) scores of 14 to 17 who had undergone percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG). Participants were randomly assigned to receive cilostazol (100 mg/d) or placebo. Outcomes included HDRS scores and adverse events.
Results: Baseline characteristics were similar between the groups (all P>.05). A significant time × treatment interaction effect on HDRS scores was observed (P=.037; partial η2=0.055). The cilostazol group showed greater reductions in HDRS scores through weeks 4 and 6 (P=.012 and P=.054, respectively). Adverse effects were not serious and were comparable between the groups (all P>.05).
Conclusion: Cilostazol was beneficial and safe for treating depressive symptoms in individuals who had recently undergone PCI or CABG. Further studies are needed to support broader clinical application.
