Influence of Cognitive Behavioral Therapy on Mood and Quality of Life After Stent Implantation in Young and Middle-Aged Patients With Coronary Heart Disease

Abstract

Cognitive behavioral therapy (CBT), established only a few decades ago, is widely used by clinical psychologists. This study aimed to investigate the effects of CBT on mental status and quality of life (QOL) after percutaneous coronary intervention (PCI) in young and middle-aged patients with coronary heart disease (CHD). Seventy-five anxiety/depression patients (mean age, 52.2 ± 6.2 years, including 8 individuals < 45 years old) with CHD treated with PCI were randomly divided into a CBT group (n = 38) and control group (n = 37). The CBT group received 8 weeks of CBT in addition to the routine postoperative treatment that was also administered to control patients. The 17-item Hamilton Depression Rating Scale (HAM-D17), Hamilton anxiety scale (HAM-A), and Coronary Revascularization Outcome Questionnaire (CROQ-PTCA-POST, Chinese version) were administered before, 3 days, and 8 weeks after intervention. HAM-D17 and HAM-A scores were decreased after treatment, but were more substantially reduced in patients that underwent CBT than those in the control group (11.7 ± 4.5 versus 15.1 ± 3.9, P = 0.001 and 10.6 ± 3.4 versus 16.5 ± 4.6, P = 0.003, respectively). QOL was improved in both groups, but overall satisfaction was higher in the CBT group compared with control patients (89.3 ± 5.2 versus 77.8 ± 9.5, P < 0.05). CBT can relieve depression and anxiety after PCI in young and middle-aged patients with CHD. CBT can improve patient QOL.
