Pak Heart J Jan ;48(3):143-6.

Objective: To determine the impact of diabetes mellitus (DM) on morbidity inpatients undergoing coronary artery bypass surgery (CABG). Methodology: This descriptive cross sectional study was conducted at Quaid-e-Azam Medical College/ Bahawal Victoria Hospital Bahawalpur from 1 May, 2014 to 31 May 2015.Patients who had undergone coronary artery bypass grafting were included. Patients operated in emergency and who underwent simultaneous valvular and congenital heart surgery were excluded. Patients were randomly divided into 2 groups, Group 1 : diabetics and Group 2: non-diabetics by computer generating method. In-hospital morbidity was defined as surgical site infection, acute kidney injury, Stroke and arrhythmias. P-value 0.05 was taken as significant. SPSS version 20 was used. Results: About 102 patients of both genders were included. The mean age of patents was 59.62+-16.15 years. Hypertension was significantly more commonly found in Diabetics compared to Non Diabetics (78.4% vs. 52.9%).Body Surface Area and pre-operative creatinine were insignificantly associated with DM. Acute kidney injury was found in 43.1% patients in diabetic group and in23.5% patients in non-diabetic group. Morbidity i.e. infections 9(17.6%) and the composite outcomes i.e. post operative stroke 1 (2%) occurred more commonly in diabetic patients as narrated by the patient. Conclusion: Patients with DM are at significantly greater risk of serious postoperative complication when compared with non-diabetics after coronary artery bypass graft surgery.
