He also ensures to get it every year to remain a step ahead of any physical ailments. However, five hard blockages were found in his heart during a resting stress test.

As per the National Institute of Health (NIH), US, it is a form of physical test that typically utilizes electrocardiography along with blood pressure monitoring and exercise, which involves a treadmill or bicycle. However, in a resting stress test, the assessment happens when the heart muscle is at rest after stress. This stress helps in identifying areas of reduced blood flow like ischemia or damage to the heart muscle, which can indicate conditions like coronary artery disease. The test involves injecting a radioactive tracer into the bloodstream, then using a special camera to take images of the heart at rest and after stress.What Is A Bypass Surgery? As per Johns Hopkins Medicine, bypass surgery or coronary artery bypass graft surgery (CABG) is a procedure used to treat coronary artery disease. Coronary artery disease (CAD) is the narrowing of the coronary arteries. These are the blood vessels that supply oxygen and nutrients to the heart muscle. CAD is caused by a build-up of fatty material within the walls of the arteries. This buildup narrows the inside of the arteries, limiting the supply of oxygen-rich blood to the heart muscle.How Does It Work? One way to treat the blocked or narrowed arteries is to bypass the blocked portion of the coronary artery with a piece of a healthy blood vessel from elsewhere in your body. Blood vessels, or grafts, used for the bypass procedure may be pieces of a vein from your leg or an artery in your chest. An artery from your wrist may also be used.ALSO READ: 4 Rare Heart Diseases That Are Becoming Common By Each Passing DayThis surgery is done to treat a blockage or narrowing of one or more of the coronary arteries.
