Heart Disease Surgery: Coronary Artery Bypass Graft

Heart disease is the number 1 cause of death in the United States. This problem is compounded by a multitude of factors, including but not limited to: Smoking, diabetes, being overweight, cancer, and genetic factors. The most common form of heart disease is coronary artery disease (CAD).

One of the most common surgeries to deal with this heart disease is an open-heart surgery called a Coronary Artery Bypass Graft (CABG). As the name implies, the purpose of the graft is to bypass a clogged artery caused by plaque buildup.

This plaque is at first caused by an onset of atherosclerosis, which is the initial buildup of plaque caused by cholesterol, fat, calcium, and other liquids and molecules found in the blood. A study found that the calcium in this plaque is also found in the creation of bones, which in turn increases the hardness of the plaque.

A vein and an artery are taken from different sections of the body and sewn around the clogged artery to equalize the pumping of oxygenating blood to and from the heart. More blood going out or into the heart would de-equalize the pressure in the heart.

Some of the risks associated with- not just coronary artery- but most heart diseases are: Stroke, heart attack, and in many cases, mortality. The coronary artery bypass graft has been proven to deal with many of these problems, improve rate of survival, fitness, and overall quality of life.

On the market today, there are several types of medicines to deal with heart disease, but these medicines are only marginally effective when compared to the surgery. A study done in 1994 proves that compared to heart medicines, the surgery greatly increased the rate of survival in medium and high risk individuals.

Though there are some complications with the surgery. Those with less body mass are usually more at risk for surgical complications, such as those who are underweight.

Open heart surgery is a risky business, but it is definitely worth it. As stated previously, Coronary artery bypass grafts are one of the most common and most trusted surgeries to deal with heart disease to date.
