CABG (Coronary artery bypass grafting) is a process that helps in restoring the blood flow to your heart. The blockage of the artery can disrupt the blood flow and leads to heart attack or similar symptoms. CABG surgery is performed for restoring the blood flow through using blood vessels of the different body parts for creating a detour around the blockage. 

What is CABG Surgery?

The CABG procedure bypasses blood close to the area of the heart’s partially or completely blocked artery. An unblocked blood vessel from your arm, chest, or leg is used in the procedure, and it is connected to the arteries above and below the obstructed ones in the heart. The blood supply to the cardiac muscles is enhanced in the new pathway.

This surgery does not helps in curing the diseases of the heart that leads to blockages, like shortness of breath and chest pain. This process may improve the functions of the heart and also helps in reducing the risk of heart disease.

Coronary bypass surgery may lead to complications during or after the process. Some complications involve the following:

  • 1. An irregular rhythm of your heart
