Risk factors of depression in coronary heart disease patients who underwent revascularization therapy / 天津医药

ABSTRACT

Objective To explore the incidence and risk factors of depression in coronary heart disease patients who underwent revascularization therapy. Methods A total of 493 patients who were admitted in Tianjin chest hospital from April 2012 to February 2013 were enrolled, among whom 258 patients acceptted coronary artery bypass grafting (CABG) and the rest 235 patients underwent percutaneous coronary intervention (PCI). Self-rating depression scale (SDS) was employed to assess the state of patients at both1 day before and 7 days after the operations. According to the postopera?tive scores, CABG group was divided into the depression group (n=90) and non-depression group (n=168) while PCI group was also divided into depression group (n=54) and non-depression group (n=181). Basic clinical datum of patients were col?lected and analyzed and independent risk factors of depression was analyzed though logistic multi-variant regression. Results The incidence of postoperative depression among CABG patients was significantly higher than that in PCI patients (P<0.05).(1)In the CABG group, age, ratio of female gender, alcohol intake, rate of past depression, length of anaesthesia, length of staying in ICU and incidence of postoperative cognitive dysfunction(POCD)were all higher in depression subgroup than those in non-depression subgroup. Female and preoperative depression were both independent risk factors for postoper?ative depression in patients underwent CABG.(2)In PCI group, ratio of female gender, blood pressure, incidence of Diabe?tes Mellitus, the rate of past Myocardiac infaction (MI), length of intervention therapy and the number of planted stents were all higher in depression subgroup than non-depression subgroup. Female, past MI and length of intervention therapy are all independent factors of post-operative depression in patients underwent PCI. Conclusion Incidence of depression in pa?tients underwent revascularization is high. Female is the dependent risk factor in both CABG group and PCI group. Com?pared with PCI, CABG had greater influence on development of depression in postoperative patients.
