Coronary Angioplasty
Coronary angioplasty, also known as percutaneous coronary intervention (PCI), is a minimally invasive procedure used to improve blood flow through narrowed or blocked coronary arteries. It is commonly performed to treat coronary artery disease, angina, and, in appropriate emergency situations, heart attacks.
During the procedure, a cardiologist guides a thin catheter through a blood vessel, usually from the wrist or groin, to the affected coronary artery. A small balloon is then inflated at the narrowed area to widen the artery. In many cases, a coronary stent is placed to help keep the artery open and maintain blood flow.
When Is Coronary Angioplasty Recommended?
Coronary angioplasty may be considered when a coronary artery has become significantly narrowed or blocked and blood flow to the heart is reduced. Depending on the individual's condition, symptoms, test results, and overall heart health, treatment may include medicines and lifestyle changes, angioplasty and stenting, or coronary artery bypass surgery (CABG).
A cardiologist may consider angioplasty when:
- Chest pain or angina is caused by reduced blood flow to the heart.
- Coronary artery narrowing is affecting blood supply to the heart muscle.
- Symptoms have not improved adequately with medicines and lifestyle measures.
- Rapid restoration of blood flow is required during certain heart attacks.
How Is Coronary Angioplasty Performed?
Before the procedure, the medical team reviews your medical history, medicines, allergies, and heart health. Depending on the circumstances, you may be asked to avoid eating or drinking for several hours and may receive medication to help you relax.
The procedure generally involves:
- A catheter is inserted into a blood vessel, commonly through the wrist or groin.
- The catheter is guided toward the coronary arteries using X-ray imaging.
- A small balloon is positioned at the narrowed section of the artery.
- The balloon is inflated to widen the narrowed area and improve blood flow.
- When appropriate, a stent is expanded inside the artery to help keep it open.
- The catheter and balloon are removed after treatment.
Coronary angioplasty is performed in a cardiac catheterization laboratory. The procedure may take from around 30 minutes to several hours depending on the complexity of the treatment, and some patients may need to stay in the hospital overnight.
Recovery After Coronary Angioplasty
Recovery varies depending on why the procedure was performed, the number and location of blockages treated, and your overall health. After a planned angioplasty, many patients can leave the hospital the same day or the following day, although some patients require a longer stay.
You may experience mild soreness or bruising around the catheter insertion site. Your cardiologist will provide instructions regarding medicines, physical activity, wound care, and follow-up.
If a stent has been placed, antiplatelet medicines may be prescribed to reduce the risk of blood clots forming inside the stent. These medicines should be taken exactly as directed by your healthcare team.
Long-term heart health also depends on managing the underlying causes of coronary artery disease. This may include stopping tobacco use, maintaining a healthy diet and weight, exercising appropriately, and controlling cholesterol, blood pressure, and blood sugar. Cardiac rehabilitation may also be recommended for suitable patients.
Risks and Considerations
Although coronary angioplasty is widely used, it is not risk-free. Possible complications include bleeding or bruising at the catheter site, blood vessel damage, abnormal heart rhythms, allergic reactions to contrast material, kidney-related complications, blood clots within a stent, heart attack, stroke, or re-narrowing of the treated artery. The likelihood of complications varies according to the patient's health and the complexity of the procedure.
Your cardiologist will evaluate the potential benefits and risks before recommending angioplasty and stent placement.
