Abstract:

BACKGROUND: As a negative event, coronary artery bypass grafting (CABG) can lead to psychological stress for patients with coronary atherosclerotic heart disease.
OBJECTIVE: To explore the change of psychological status and their influencing factors prior to and after CABG in patients with coronary disease.
METHODS: A total of 82 patients received CABG at the Department of Cardiovascular Surgery, Fifth Hospital Affiliated to Xinjiang Medical University, from January 2007 to June 2009, were selected. All patients had normal cognitive and comprehension ability, without mental disorder history, and agreed to join the follow up. The patients were examined by the Chinese version of Symptom Check List-90 (SCL-90) in a day before operation and in the day before leaving hospital.
RESULTS AND CONCLUSION: Prior to CABG, the factorial scores of global severity index, positive symptoms severity index, somatization, depression, anxiety, phobic were higher than norm, and the scores were significantly decrease on interpersonal sensitivity and paranoid ideation. After the procedure, the depression and anxiety score were higher than that before operation  (P < 0.05-0.01). The identical characteristics were that patients exhibited obviously depression and anxiety prior to and after operation. The depression and anxiety can increase side effects before and after CABG. The psychological state of the patients should be routinely assessed in the procedure, and at the same time the reasonable psychological intervention should be carried out, which can reduce the intraoperative complication and occurrence of cardiovascular events.
