INTRODUCTION: Depression is much frequent in patients undergoing CABGS. However,
severity was reduced post operatively. Counseling and psychosocial interventions can play an
important role in recovery and functionality of patients.
OBJECTIVE: To compare the frequency of depression in patients undergoing coronary artery
bypass grafting surgery (CABGS) before the surgery, at discharge and at six months follow up.
DESIGN: Prospective, observational study conducted from Dec 2008 to Dec 2009.
SETTING: National Institute of Cardiovascular Diseases (NICVD) Karachi.
METHODS: One hundred and thirty four (134) patients of 18+ years old who were consecutively
listed for first time CABGS were included in the study after fulfilling the inclusion and exclusion
criteria and addressing the ethical issues. ICD-10 criteria to diagnose and Hamilton Rating Scale
for Depression (HAM-D) were applied to assess the frequency and severity of depressive
disorder respectively. Results were analyzed using SPSS version 17.0.
RESULTS: One hundred and thirty four (134) patients undergoing CABGS fulfilled the criteria
for Depressive disorder. One hundred and thirteen (84.3%) were male and 21 (15.7%) were
female with age range 33 to 75 years (mean 53.7 ±SD 8.57). Preoperatively 132 (98.5%)
patients and postoperatively 108 (80.6%) patients were depressed. At 6 months follow up which
was available in 73 patients, only 12 (16.4%) were found depressed. Both genders were almost
equally affected. Surprisingly age, ethnicity, education and co-morbids did not show a
CONCLUSION: Depression is commonly reported before and after cardiac surgery procedures
and it significantly influences the quality of life of the patients undergoing CABGS. The
consequences can increase morbidity and mortality.
