Stents for Coronary Artery DiseaseIf you have coronary heart disease, plaque builds up inside your coronary arteries, eventually blocking the flow of oxygen-rich blood to the heart muscle. This buildup is called atherosclerosis, and the blood is usually cut off when an artery is blocked by a blood clot, causing a heart attack.
A cardiac stent is a small, expandable metal or plastic tube that is inserted into a narrowed artery to keep it open. It can also be called a heart stent or coronary stent. To open larger arteries, your surgeon may use a stent graft made of fabric.
Usually blood vessel blockages are caused by a buildup of plaque. You may need an emergency stent if your coronary artery is blocked and/or you suffer a heart attack. The surgeon will place a catheter into the blocked coronary artery, followed by a balloon angioplasty and a stent in the artery.
The Stent Procedure
A stent procedure is much less invasive than coronary artery bypass surgery. Generally, recovery after a stent surgery results in less discomfort and a shorter recovery time. Your doctor will usually recommend blood-thinning drugs such as aspirin to prevent blood clots.
Before getting a stent, your doctor will tell you not to take any drugs that will make it harder for your blood to clot. During the cardiac stent procedure, the surgeon will make a small incision – usually in the groin or arm – and use a catheter to guide surgical tools through your blood vessels.
He or she may use an angiogram to help guide the stent to the broken or blocked blood vessel. Once the stent is placed, the surgeon will close the incision. Most patients remain in the hospital overnight after a heart stent surgery.
Many patients are able to return to work after a week, however, often those who have undergone emergency stent surgery take longer to recover. Your physician will recommend no heavy lifting or strenuous activity for a few weeks after surgery.
