Cardiac rehabilitation programme

Overview

A cardiac rehabilitation programme is a structured plan of exercise, education, and support designed to help you recover after heart surgery or a heart event like a heart attack. It aims to improve your heart health, boost your confidence, and reduce the risk of future heart problems.

Yes, cardiac rehabilitation is offered to most people who have had heart surgery, a heart attack, or other serious heart conditions. Many hospitals have dedicated rehab teams to guide you through the programme.

It affects anyone who has experienced a heart-related event or procedure, such as coronary artery bypass surgery, heart valve repair, or a heart attack. Both men and women of all ages can benefit, and programmes are tailored to individual needs.

Symptoms

Causes

Main causes

• You are offered cardiac rehab because you had a heart condition or surgery. The underlying cause of that heart problem is often coronary artery disease (narrowed or blocked blood vessels), heart valve disease, or damage from a heart attack.

Risk factors

• High blood pressure
• High cholesterol
• Smoking
• Being overweight or obese

When to see a doctor

See a doctor urgently if:

• If you have been invited to cardiac rehab but experience any new or worsening symptoms like chest pain, dizziness, or shortness of breath, see your doctor right away or call your local emergency number.

Book a routine appointment if:

• Contact your doctor or cardiac rehab team if you have questions about starting or continuing the programme, or if you need help with transportation or scheduling.

Diagnosis

You do not get diagnosed with cardiac rehab – it is a treatment programme. You are referred to it after a diagnosis of a heart condition, such as after heart surgery, a heart attack, or angina. Your doctor or hospital team will discuss whether rehab is right for you.

Tests that may be done

• Before starting rehab, you may have a health assessment that includes checking your blood pressure, heart rate, and possibly an electrocardiogram (ECG) to see your heart's rhythm.
• You might also have a blood test to check cholesterol and blood sugar levels.
• Your fitness level may be assessed with a simple walk test or other measures.

What to expect at your appointment

The cardiac rehab team will create a personalised plan for you. You will attend sessions at a hospital or community centre, usually once or twice a week for several weeks. Each session includes supervised exercise and group education on topics like healthy eating, medications, and emotional wellbeing.

Treatment

Cardiac rehabilitation is a treatment itself. It helps you recover and lowers your risk of future heart problems. The programme combines supervised exercise, education on heart-healthy living, and support for emotional health.

Self-care at home

• Follow the exercise plan your rehab team gives you, even on days you do not attend a session.
• Eat a balanced diet with plenty of vegetables, fruits, whole grains, and lean protein. Reduce salt, sugar, and unhealthy fats.
• Take all prescribed medications as directed by your doctor – do not stop or change them without advice.

Medical treatments

Your doctor may prescribe medications to manage blood pressure, cholesterol, or to prevent blood clots. These are part of your overall care. The cardiac rehab team will explain what each medicine does and how to take it safely. Never change your dose or stop a medicine without talking to your doctor.

When is surgery considered?

Cardiac rehab is often recommended after heart surgery, such as bypass or valve repair. The programme helps you recover strength and confidence. If you need further surgery in the future, your doctor will discuss it based on your condition.

Living with this condition

Participating in cardiac rehab becomes part of your routine. You will learn how to gradually increase your activities at home and work. Many people find they can return to normal daily tasks and even hobbies they enjoy, with some adjustments.

Lifestyle tips

• Stay physically active – aim for at least 30 minutes of moderate activity most days, as guided by your rehab team.
• Avoid smoking and limit alcohol.
• Manage stress with relaxation techniques, talking to friends, or seeking professional support.
• Get enough sleep – aim for 7–9 hours per night.

Diet and exercise

Your rehab team will give you specific advice, but generally, a heart-healthy diet includes plenty of vegetables, fruits, whole grains, fish, and lean meats while limiting processed foods. Exercise should include both aerobic activity (like walking or cycling) and strength training, starting gently and building up.

Prevention

Cardiac rehab itself is about preventing further heart problems. While you cannot undo the heart condition that led to your surgery, the programme helps prevent future heart attacks, hospital stays, and complications. Many risk factors like smoking, diet, and activity level can be changed.

Screening programmes

You will have regular check-ups with your GP or cardiologist to monitor your heart health, blood pressure, and cholesterol. Your cardiac rehab team may also screen your progress during the programme.

Complications

If left untreated

• If you do not take part in cardiac rehab after a heart event or surgery, you may be at higher risk of another heart attack or needing more surgery.
• You might struggle with low confidence and avoid activity, which can lead to weaker muscles and poorer overall health.
• Without the education from rehab, you may continue unhealthy habits that increase your risk.

Long-term outlook

The outlook is very positive. People who complete cardiac rehab often feel stronger, more confident, and have a better quality of life. They are less likely to be readmitted to hospital and have a lower risk of future heart problems. With commitment, you can make lasting improvements to your heart health.
