Plain English Summary
Background and study aims
Coronary artery disease is the term that describes what happens when the heart's blood supply is blocked or interrupted by a build-up of fatty substances in the coronary arteries. Coronary artery bypass grafting (CABG) is also known as bypass surgery, a heart bypass, or coronary artery bypass surgery. Type 2 diabetes is a common condition that causes the level of sugar (glucose) in the blood to become too high.
- Define the factors that can predict hospital mortality after coronary bypass surgery in patients with type 2 diabetes.
- Evaluate adverse heart and brain events that occur after surgery.
- Evaluate the risk of readmissions to hospital and the need for surgical or percutaneous myocardial revascularization.
- Calculate medium and long term mortality and identify its predictive factors.
Who can participate?
Patients at Mohammed V teaching military hospital, who have type 2 diabetes mellitus and have undergone a coronary bypass graft to treat coronary artery disease.
What does the study involve?
It concerns only the study of records and collection of data already stored in our local database with no impact on the patient's health and discrimination.
What are the possible benefits and risks of participating?
The study is performed after discharge of patients and does not concern a change of treatment or intervention or anesthesia. Patients participating in the study are not exposed to any risk of side or adverse effects.
Where is the study run from?
Cardiac surgery department - Mohammed V teaching military hospital, Rabat, Morocco.
When is the study starting and how long is it expected to run for?
January 2000 to January 2019.
Who is funding the study?
Université Mohammed V de Rabat, Morocco.

Coronary artery bypass in diabetes type 2 patients
This is a retrospective study, all patients were already operated on and discharged from the hospital. Data will be collected from the local database and processed without any therapeutic change or intervention.
Data from diabetic patients who underwent coronary artery bypass grafting surgery since 2000 are included. Treatment was according to the usual protocol of the cardiac surgery department and they were followed by our outpatient clinic system.
Primary outcome measure
Gathered from patient records from time of operation to end of study:
1. Incidence of postoperative major cardiovascular and cerebral events (MACCE).
2. Incidence of re-hospitalizations, re-interventions and the need for revascularization.
3. The mortality in the medium and long term.
