Risks and benefits of angioplasty

Overview

Angioplasty is a procedure to open narrowed or blocked blood vessels that supply the heart. A tiny balloon is inflated inside the vessel to widen it, and often a small mesh tube called a stent is left in place to keep it open.

Angioplasty is a very common procedure worldwide. Hundreds of thousands are done each year, especially for people with coronary artery disease.

It is most often used in adults who have significant blockages in the heart arteries, often due to a buildup of fatty plaque. This includes people with stable angina, unstable angina, or after a heart attack.

Symptoms

Common symptoms

• Chest pain or discomfort (angina) that feels like pressure, squeezing, or heaviness
• Shortness of breath during activity or at rest
• Pain in the arms, neck, jaw, shoulder, or back
• Nausea, indigestion, or extreme fatigue

Symptoms in children

• Angioplasty is rarely performed in children. When it is, symptoms might include chest pain with exercise, poor growth, or fainting spells.

Symptoms in older adults

• In older adults, symptoms may be less typical, such as general weakness, confusion, or shortness of breath without chest pain.

Causes

Main causes

• Atherosclerosis: a buildup of cholesterol, fat, and other substances (plaque) inside the artery walls that narrows or blocks blood flow.

Risk factors

• High blood pressure
• High cholesterol
• Smoking or tobacco use
• Diabetes
• Being overweight or obese
• Lack of physical activity
• Unhealthy diet high in saturated fats and salt
• Family history of heart disease
• Older age (men over 45, women over 55)

When to see a doctor

See a doctor urgently if:

• If you have new or worsening chest pain, shortness of breath, or any symptoms of a heart attack, call your local emergency number immediately.

Book a routine appointment if:

• If you have risk factors for heart disease, see your doctor for regular check-ups and discuss any symptoms like chest pain or fatigue.

Diagnosis

Doctors use tests to see if your heart arteries are narrowed. If a blockage is found, they may recommend angioplasty to open it.

Tests that may be done

• Electrocardiogram (ECG or EKG) – measures heart's electrical activity
• Stress test (exercise or medication) – checks how heart works under stress
• Coronary angiography – a special X-ray using dye to see blockages inside arteries (often done just before angioplasty)
• Blood tests – check for heart enzyme levels and cholesterol

What to expect at your appointment

If you need angioplasty, you will be given medicine to help you relax. Your doctor numbs the area where a thin tube (catheter) is inserted. The tube is guided to your heart, and a balloon is inflated to open the blockage. You may feel some pressure but usually no sharp pain. Most people stay in hospital for one to two days.

Treatment

Angioplasty (also called percutaneous coronary intervention or PCI) is one treatment for blocked arteries. It opens the vessel quickly and improves blood flow, but lifestyle changes and medicines are often needed afterward to keep arteries healthy.

Self-care at home

• Take all prescribed medications as directed by your doctor
• Quit smoking – it is the single most important step
• Eat a heart-healthy diet low in saturated fats, salt, and added sugars
• Get regular physical activity (walking is great – ask your doctor what is safe)
• Manage stress through relaxation techniques or talking to someone

Medical treatments

Before and after angioplasty, doctors may prescribe medicines to prevent blood clots, control blood pressure, lower cholesterol, or manage diabetes. Always take them exactly as prescribed. Do not stop without talking to your doctor. In some cases, other procedures like bypass surgery may be recommended if blockages are too complex or widespread.

When is surgery considered?

Angioplasty is a minimally invasive procedure, not open surgery. However, if the blockages are very severe or in certain locations, your doctor might recommend coronary artery bypass grafting (CABG), which is a type of open-heart surgery.

Living with this condition

After angioplasty, most people feel much better. You can usually return to work within a week, but avoid heavy lifting or strenuous activity for a few weeks. Attend all follow-up appointments to check how you are recovering.

Lifestyle tips

• Follow a heart-healthy diet – plenty of fruits, vegetables, whole grains, and lean protein
• Aim for 30 minutes of moderate exercise most days (after your doctor says it is safe)
• Limit alcohol – no more than one drink per day for women, two for men
• Avoid smoking and secondhand smoke
• Keep your blood pressure, cholesterol, and diabetes under control

Diet and exercise

Eat less red meat, fried foods, and salty snacks. Choose fish, skinless poultry, beans, and nuts. For exercise, start slowly – even a short walk every day helps. Your doctor may recommend a cardiac rehabilitation program to guide you safely.

Mental health and emotional wellbeing

Having a heart procedure can be stressful. It is normal to feel anxious or worried. Talking to your doctor, a counsellor, or joining a support group can help. Do not ignore feelings of depression or overwhelming worry – ask for help.

Prevention

You can reduce your risk of needing angioplasty by preventing or managing heart disease. A healthy lifestyle and regular check-ups are key.

Vaccines

Get your annual flu shot and pneumonia vaccine if recommended – infections can stress the heart.

Screening programmes

If you have risk factors (like high blood pressure, high cholesterol, diabetes, or a family history), see your doctor for regular blood pressure, cholesterol, and blood sugar checks.

Complications

If left untreated

• Untreated blocked arteries can lead to chest pain that limits your activity, a heart attack (which can damage heart muscle), or sudden cardiac arrest.

Long-term outlook

Angioplasty has a very high success rate and can dramatically improve quality of life. Most people live long, active lives after the procedure, especially if they adopt heart-healthy habits. However, it is not a cure – you still need to manage your condition with medication and lifestyle changes to keep your arteries clear.
