Coronary Artery Bypass Grafting (CABG) is the most commonly performed procedure for treatment of patients with coronary heart diseases. Arteries or veins from elsewhere in the patient’s body are grafted to the coronary arteries to bypass atherosclerotic narrowing and improve the blood supply to the myocardium (heart muscle).
CABG: Coronary Artery Bypass Grafting / Heart Bypass surgery
CABG is performed to a person who is suffering from Coronary Artery Disease that occurs due to hardening of the arteries which supplies blood to the heart muscle. Coronary Artery Bypass Grafting (CABG) surgery re-establishes sufficient blood flow to deliver oxygen and nutrients to the heart muscle. Other names of CABG are Bypass surgery, Coronary artery bypass surgery and Heart bypass surgery.

Diagnostic Test for Coronary Artery disease:

- ECG: Electrocardiogram is a test to detect and record heart’s electrical activity and help to locate the heart problem.
- Stress Test: Basically exercise test to make heart work hard.
- Echocardiography: uses sound waves to create a moving picture of heart.
- Coronary Angiography: uses dyes and x-rays to show the inside view of the arteries.
Procedure of CABG surgery:
- 1st step: Doctor will sew the sternum together with small wires i.e. those that are used to repair a broken bone.
- 2nd step: Doctor will insert tubes into the chest to drain blood and other fluids around the heart.
- 3rd step: Doctor will sew the skin over the sternum back together.
