About Angioplasty
Angioplasty is done to open blocked coronary arteries. During this, blood flow is returned to the heart muscle without open-heart surgery. Angioplasty can be done in an emergency setting such as a heart attack. This procedure puts a long, thin tube (catheter) into a blood vessel and guides it to the blocked coronary artery. A long, thin tube (catheter) is put into a blood vessel during angioplasty and guided toward the blocked coronary artery. The catheter has a tiny balloon at its tip. Once the catheter is in place, the balloon is inflated at the narrowed area of the heart artery; pressing the plaque or blood clot against the sides of the artery, making more room for blood flow. Not all coronary artery disease (CAD) can be treated with angioplasty.
What condition can Angioplasty treat?
Angioplasty is a medical procedure that is primarily used to treat conditions associated with narrowed or blocked blood vessels, particularly in the context of coronary artery disease (CAD). CAD is the most common type of heart disease and occurs when the coronary arteries, responsible for supplying blood to the heart muscle, become hardened and narrowed due to the buildup of cholesterol and plaque on their inner walls. This condition can lead to serious complications such as chest pain (angina), shortness of breath, and even heart attacks.
The angioplasty procedure involves the insertion of a catheter with a small balloon at its tip into the affected artery. Once in place, the balloon is inflated to compress the plaque against the artery wall, thereby widening the vessel and restoring proper blood flow to the heart muscle. Often, a stent—a small wire mesh tube—is also placed during the procedure to help keep the artery open long-term.
Apart from CAD, angioplasty can also be used to treat peripheral artery disease (PAD), which occurs when the arteries that supply blood to the limbs, usually the legs, become blocked. Similarly, it can address renal artery stenosis, a condition where the arteries that provide blood to the kidneys are narrowed, and carotid artery disease, which involves blockages in the arteries that supply blood to the brain.
Who needs an Angioplasty?
Angioplasty, a medical procedure to widen narrowed or obstructed arteries, is typically recommended for individuals experiencing significant heart-related symptoms or those who have suffered a heart attack. The primary candidates for angioplasty are those with coronary artery disease (CAD), where the coronary arteries become narrowed due to a buildup of plaque, a condition known as atherosclerosis.
Patients who benefit most from angioplasty are those experiencing unstable angina or a heart attack. Unstable angina is a condition characterized by severe chest pain that occurs at rest or with minimal exertion, signaling that a heart attack might be imminent. In such emergency situations, angioplasty can be life-saving, as it quickly restores blood flow to the heart muscle, reducing damage and improving survival rates.
Individuals who have stable angina, which is chest pain that occurs with activity or stress, may also be considered for angioplasty if their symptoms are not adequately controlled with medication. In these cases, angioplasty can significantly improve quality of life by reducing pain and increasing the ability to perform daily activities.
Angioplasty may also be advised after a stress test indicates a potential blockage in one or more of the heart's arteries. If the stress test results suggest that blood flow is significantly restricted during exercise, angioplasty can help prevent a heart attack by improving blood supply to the heart muscle.
It's important to note that not everyone with CAD needs angioplasty. Many individuals with mild symptoms or those whose condition is stable can manage their disease effectively with medications and lifestyle changes. These non-invasive treatments can be just as effective for preventing heart attacks and death as angioplasty in certain cases.
What are the risks of angioplasty?
Possible risks linked to angioplasty, stenting, atherectomy, and related procedures include:
Bleeding at the site where the catheter is put into the body (usually the groin, wrist, or arm)
Blood clot or damage to the blood vessel from the catheter
A blood clot within the treated blood vessel
Infection at the catheter insertion site
Abnormal heart rhythms
Heart attack
Stroke
Chest pain or discomfort
Rupture of the coronary artery or complete closing of the coronary artery, needing open-heart surgery
Allergic reaction to the contrast dye used
Kidney damage from the contrast dye
Angioplasty recovery
In case a patient goes under a planned coronary angioplasty, they should be able to return to work after a week. But for patients who need emergency angioplasty following a heart attack, it may be several weeks or months before they recover fully and can return to work.
