Day of angioplasty
Informed by recognized medical guidance
Overview
Angioplasty is a procedure to open up a narrowed or blocked blood vessel, usually in the heart, legs, or kidneys. It uses a small balloon and often a tiny mesh tube called a stent to restore blood flow. For most people, angioplasty is done on the same day you arrive at the hospital.
Key facts
- Angioplasty is usually done through a small puncture in your groin or wrist, not a large cut.
- You may be awake during the procedure, but the area is numbed so you don’t feel pain.
- Most people go home the next day, sometimes even the same day.
Yes, angioplasty is a common procedure worldwide. In the UK alone, thousands of people have it each year to treat heart and artery problems.
Angioplasty is typically done for people with coronary artery disease (narrowed heart arteries), peripheral artery disease (narrowed leg arteries), or kidney artery narrowing. It is more common in older adults, but can be needed at any age.
Symptoms
- Sudden severe chest pain that does not go away with rest.
- Difficulty breathing or gasping for air.
- Fainting or sudden collapse.
- ⚠New or worsening chest pain that lasts more than a few minutes.
- ⚠Unexplained leg or arm pain with swelling or colour change.
Common symptoms
- Chest pain or heaviness (angina) during activity, which improves with rest.
- Shortness of breath, especially with exertion.
- Leg pain or cramping when walking that goes away with rest.
Symptoms in children
- Angioplasty in children is rare, but if needed, symptoms may include chest pain, fainting, or poor growth.
Symptoms in older adults
- Symptoms may be less typical, such as fatigue, confusion, or shortness of breath without chest pain.
Causes
Main causes
- The most common cause is a buildup of fatty deposits (plaques) inside the arteries, a condition called atherosclerosis.
Risk factors
- Smoking
- High blood pressure
- High cholesterol
- Diabetes
- Lack of physical activity
- Being overweight
- Family history of heart disease
When to see a doctor
See a doctor urgently if:
- If you have sudden, severe chest pain or shortness of breath that does not improve with rest.
Book a routine appointment if:
- If you experience chest pain, leg cramps when walking, or other symptoms that keep coming back.
Diagnosis
Your doctor will ask about your symptoms, medical history, and risk factors. They may do tests to see if your arteries are narrowed.
Tests that may be done
- Blood tests to check cholesterol, blood sugar, and kidney function.
- Electrocardiogram (ECG) to check heart rhythm.
- Coronary angiography – a special dye is injected into your arteries and X‑ray pictures are taken.
What to expect at your appointment
Before the day of angioplasty, you’ll have a consultation where the doctor explains the risks and benefits. You’ll be told when to stop eating or drinking. On the day, you will change into a hospital gown, have a small needle put in your arm for fluids, and be taken to the procedure room.
Treatment
Angioplasty is the main treatment for opening blocked arteries. It is not a cure, but it can relieve symptoms and reduce the risk of heart attack or stroke. After the procedure, lifestyle changes and medicines are needed to keep the arteries healthy.
Self-care at home
- Follow your doctor’s instructions about activity – you may need to avoid heavy lifting for a few days.
- Keep the puncture site clean and dry.
- Take any prescribed medicines exactly as told – do not stop without talking to your doctor.
Medical treatments
After angioplasty, doctors usually prescribe medicines to prevent blood clots and control conditions like high blood pressure or high cholesterol. These are often taken long‑term. Your doctor will explain the dose and schedule.
When is surgery considered?
In some cases, angioplasty may not be possible or effective, and bypass surgery (where a new route is created around the blockage) may be recommended.
Living with this condition
Most people feel better soon after angioplasty. You may need to take a few days off work. Listen to your body and gradually get back to normal activities.
Lifestyle tips
- Quit smoking – it is the best thing you can do for your arteries.
- Manage stress with relaxation techniques or talking to someone.
- Keep a healthy weight.
Diet and exercise
Eat a heart‑healthy diet rich in fruits, vegetables, whole grains, and lean proteins. Limit salt, sugar, and saturated fats. Aim for at least 30 minutes of moderate exercise most days – start slowly and get your doctor’s OK first.
Mental health and emotional wellbeing
It is normal to feel anxious or down after a procedure. Talk to your doctor or a counsellor if these feelings last. Many people find support groups helpful.
Prevention
While you cannot always prevent artery blockages, you can greatly reduce your risk by not smoking, managing blood pressure and cholesterol, staying active, eating well, and controlling diabetes.
Screening programmes
Screening tests like blood pressure checks and cholesterol tests can help find problems early. Talk to your doctor about when you should be tested.
Complications
If left untreated
- If narrowed arteries are not treated, they can lead to heart attack, stroke, or damage to other organs.
- Untreated leg artery blockages can cause pain that limits walking, and in severe cases lead to amputation.
Long-term outlook
For most people, angioplasty is very successful in opening blocked arteries and improving symptoms. With good self‑care and medical follow‑up, many people live full, active lives for many years afterward.
