Surgery
In severe cases when lifestyle changes and medications cannot improve symptoms, surgery is needed to treat coronary heart disease. The main goal is to restore blood flow to the heart and reduce the risk of further complications. A common option is percutaneous coronary intervention. During this procedure, the narrow area of the artery will be enlarged so that a stent can be inserted to open it. Another procedure is the coronary artery bypass. It removes a healthy vein or artery from other parts and then connects this part to help blood bypass a blockage. [10]
