Coronary Artery Bypass Grafting (CABG) is a major open-heart surgery to improve blood flow to the heart by creating new pathways around blocked coronary arteries. The need for it is typically confirmed by symptoms like chest pain (angina), shortness of breath, and fatigue, often diagnosed after a heart attack or through tests like an angiogram. Pre-surgery treatments may include medications and angioplasty, but CABG is recommended for severe, multiple blockages. The procedure involves taking a healthy blood vessel from the chest, leg, or arm and grafting it to bypass the blocked arteries. It is crucial to find a highly experienced Cardiothoracic Surgeon at a well-regarded cardiac hospital with a dedicated intensive care unit. The cost is significant, often ranging from $70,000 to $200,000, making insurance pre-authorization essential. Life after surgery requires a lifelong commitment to guidance including cardiac rehabilitation, a strict heart-healthy diet, regular exercise, quitting smoking, and taking medications to ensure the long-term success of the bypass grafts.
