Coronary Artery Bypass Graft is a kind of surgery carried on to repair blood flow to the heart muscle. The surgery is conducted by using various blood vessels from other parts of the body in order to supply a path around the obstructed coronary arteries. This allows ample blood flow which delivers oxygen and necessary nutrients to the heart muscle. This surgery is one of the most commonly performed major operations in western countries. However, coronary artery bypass graft surgery is also carried out successfully in India as well.
Reasons why one should go for Coronary Artery Bypass Graft
Coronary artery bypass grafting is done to restore normal blood supply to the heart muscle. Your doctor will advise you for Coronary Artery Bypass Graft when:
- Diagnosis results in stern blockages in the main artery or obstacles in several blood vessels
- When you suffer from constant chest pain which is not improved with drug therapy
Risks involved in the surgery
CABG surgery involves fewer risks. The overall mortality related to this surgery is 3-4%. In some cases about 5 to 10% of patients suffer from heart attack which is the main cause of death. Due to bleeding sometimes 5% of patients require exploration too. The second surgery most often accelerates the risk of chest contamination and lung complications. Heart strokes also occur in 1-2% primarily among elder patients.
Pre and Post Treatment Care/Requirements
Your doctor will probably do the following:
- A thorough physical exam
- An X ray of your chest
- ECG,EKG (Electrocardiogram)- This is a test that traces heart’s movement by calculating electrical currents via the heart muscle
- A test called coronary angiogram that determines the point and spot of the blockage in the blood vessels in the heart
- Before one week of CABG avoid taking aspirin or any anti-inflammatory drugs unless prescribed by your doctor. Also make sure if you are not taking any blood thinning medicine such as Warfarin, Clopidogrel or Tricodine.
