Cardiac rehabilitation programme
Informed by recognized medical guidance
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.
Key facts
- Cardiac rehab is a medically supervised programme that typically lasts several weeks to months.
- It includes physical activity tailored to your ability, along with advice on healthy eating, stress management, and medication.
- Taking part can significantly lower your chances of having another heart problem and improve your quality of life.
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
- Chest pain or pressure that doesn't go away, especially if it spreads to your arms, back, neck, or jaw
- Sudden shortness of breath with or without chest pain
- Fainting or feeling like you might pass out
- A fast or irregular heartbeat that feels alarming and doesn't settle
- ⚠New or worsening chest discomfort that goes away with rest but keeps coming back
- ⚠Unexplained swelling in your ankles or feet
- ⚠Feeling unusually tired or weak for no clear reason
- ⚠Any symptoms that worry you but are not sudden or severe
Common symptoms
- Cardiac rehab itself doesn't have symptoms — it is a recovery programme. However, you may be referred after experiencing symptoms like chest pain, shortness of breath, or fatigue that led to your heart surgery or event.
Symptoms in children
- Cardiac rehab is very rare for children, but if a child has had heart surgery, a specialist paediatric programme may be offered. Symptoms leading to that would be related to congenital heart conditions.
Symptoms in older adults
- Older adults may join cardiac rehab after heart surgery or a heart attack. They might have had symptoms such as chest discomfort, dizziness, or reduced ability to do daily activities. The programme is adjusted to their fitness level.
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
- Diabetes
- Not being physically active
- An unhealthy diet high in salt, fat, and sugar
- Family history of heart disease
- Stress and anxiety
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.
Mental health and emotional wellbeing
It is common to feel anxious, depressed, or worried after a heart event or surgery. Cardiac rehab includes emotional support and ways to cope. If you feel overwhelmed, talk to your doctor or a counsellor. You are not alone.
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.
