The Need for Coronary Artery Bypass Graft Surgery

A normal coronary artery is responsible for transferring blood to the cardiac muscles. Damage or disease can lead to the deposition of plaque on its inner wall, which solidifies over time and obstructs the passage of blood. Hence, the heart muscle doesn’t get adequate blood. Coronary disease (i.e., blockage in coronary arteries) usually present with symptoms of Angina (chest pain) and breathlessness.

The line of treatment depends upon the percentage and the number of coronary arteries that are blocked. If the blockage is less than 70%, then medical management i.e., by medicine and lifestyle modification is advised. Non-surgical PCI (percutaneous coronary intervention i.e., coronary stent) is done when the blockage is more than 70% and present in one or two coronary arteries.

Coronary artery bypass graft surgery is considered when there is a severe obstruction (more than 70%) and multivessel coronary disease. Coronary artery bypass graft surgery is an open heart procedure, in which the surgeon makes a wide incision on the patient’s chest, exposes the heart, and stops it while putting the responsibility of maintaining the body circulation on the bypass machine. The blocked coronary artery is bypassed by using a healthy artery from elsewhere in your body. The recovery could take 1 or 2 months.

The risk of CABG’S multiplies if you are an extreme smoker, above 75 years of age, suffering from diabetes, lung diseases, kidney diseases, or any other arterial problems. Either way, if you consult at clinics in Dubai to get treated for coronary cardiac issues, a set of tests will be conducted before they qualify you for Heart Bypass.
