Cardiac Rehabilitation

Support for recovery, movement and confidence after a heart problem

Recovering after a heart problem, procedure or surgery can affect physical fitness, confidence and the way you approach everyday activity.

Cardiac rehabilitation provides structured support to help you gradually return to movement and exercise at an appropriate level. The programme considers your medical history, current physical ability and the activities you would like to return to.

The aim is to help you become more active safely while building strength, stamina and confidence over time.

What is cardiac rehabilitation?

Cardiac rehabilitation is a planned programme of exercise, education and support for people recovering from certain heart conditions or cardiac procedures.

It is not simply a fitness programme. Exercise is introduced according to your medical condition, stage of recovery and individual ability.

Rehabilitation may involve walking, cardiovascular exercise, strengthening, activity guidance and practical advice about returning to normal daily life.

Who may benefit from cardiac rehabilitation?

Cardiac rehabilitation may be recommended following:

• A heart attack
• Coronary angioplasty or stent placement
• Coronary artery bypass surgery
• Heart valve surgery
• Certain other cardiac procedures
• A period of reduced activity because of a heart condition
• Some cases of stable heart failure
• A medically supervised return to exercise following cardiac treatment

Whether cardiac rehabilitation is appropriate depends on your individual medical situation and the guidance provided by your cardiology or medical team.

What happens during your initial assessment?

Before beginning an exercise programme, the physiotherapist will discuss your cardiac history, treatment and current symptoms.

You may be asked about:

• Your recent heart condition or procedure
• Current medication
• Previous levels of physical activity
• Breathlessness or fatigue
• Chest discomfort
• Dizziness or light-headedness
• Other medical conditions
• Current walking ability
• Work and everyday activities
• Your confidence with exercise
• What you would like to return to doing

Depending on your circumstances, the assessment may also consider:

• Heart rate
• Blood pressure
• Walking tolerance
• General strength
• Balance and mobility
• How your body responds to light physical activity

This information helps establish an appropriate starting point for rehabilitation.

What rehabilitation may include

The programme will depend on your condition and stage of recovery.

Walking and cardiovascular exercise

Walking is often a practical starting point for rebuilding cardiovascular fitness.

The distance, pace and duration can begin at a manageable level and gradually increase as your ability improves.

Other forms of cardiovascular activity may also be introduced where appropriate.

Strengthening exercises

Periods of illness, hospital admission or reduced activity can lead to a loss of muscle strength.

Gradual strengthening may be used to improve:

• Leg strength
• Upper-body strength
• General mobility
• Ability to use stairs
• Lifting and carrying
• Everyday physical function

Strength exercises are progressed according to your recovery and medical guidance.

Mobility and movement

If you have spent a significant amount of time resting or recovering in hospital, normal movement may initially feel more tiring or difficult.

Rehabilitation may include:

• Getting up from a chair
• Walking
• Using stairs
• General mobility
• Balance exercises
• Gradually increasing time spent active

Education and self-management

Understanding how to exercise safely is an important part of cardiac rehabilitation.

You may receive guidance on:

• How hard to exercise
• How to warm up and cool down
• Recognising changes in symptoms
• Gradually increasing activity
• Balancing activity and recovery
• Returning to normal daily activities

Home exercise programme

You may be given a structured programme to complete independently between appointments.

This can be adjusted as your cardiovascular fitness, strength and confidence improve.

Recovery after a heart attack

After a heart attack, people often feel uncertain about how much activity is safe.

It is common for normal activities to feel more tiring initially, particularly following a hospital admission and a period of reduced movement.

Cardiac rehabilitation provides a gradual way of returning to activity.

Early rehabilitation may involve:

• Short periods of walking
• Gentle movement
• Gradually increasing daily activity
• Monitoring how you respond to exercise
• Building confidence with normal movement

As recovery progresses, exercise can become more structured and challenging.

The pace of progression is individual and should follow the recommendations of your cardiac team.

Rehabilitation after angioplasty or stent placement

After coronary angioplasty or stent placement, you may be advised to gradually return to normal physical activity.

The rehabilitation programme may consider both your heart condition and your recovery from the procedure.

Depending on medical guidance, rehabilitation may include:

• Walking
• Cardiovascular exercise
• Strengthening
• Increasing general activity
• Returning to work
• Returning to recreational exercise

Progress should be based on your symptoms, current fitness and cardiology recommendations rather than simply returning immediately to your previous routine.

Rehabilitation after heart surgery

Heart surgery can involve a longer physical recovery.

Following procedures such as coronary bypass or valve surgery, people may initially experience reduced stamina, weakness and fatigue.

Rehabilitation may focus on:

• Gradually increasing walking
• Improving general strength
• Rebuilding cardiovascular fitness
• Managing stairs
• Returning to everyday activities
• Increasing independence
• Returning gradually to exercise

Following surgery through the breastbone, there may also be temporary restrictions around lifting and upper-body activity while healing takes place.

Your rehabilitation programme should follow the specific guidance provided by your surgical team.

Cardiac rehabilitation and heart failure

Some people with stable heart failure may benefit from structured exercise rehabilitation.

Symptoms such as fatigue and breathlessness can make people understandably cautious about activity.

A programme may begin with relatively low levels of exercise and gradually progress according to how your body responds.

Treatment may focus on:

• Walking tolerance
• General cardiovascular fitness
• Leg strength
• Everyday mobility
• Balance
• Confidence with activity

Any exercise programme for heart failure should take account of your current medical condition and treatment plan.

Building cardiovascular fitness gradually

Cardiac rehabilitation is not about exercising as hard as possible.

A useful programme begins at a level your body can manage and gradually increases the amount of work over time.

Progress may involve increasing:

• Walking duration
• Walking pace
• Exercise time
• Resistance
• Number of repetitions
• Frequency of activity

Several smaller changes over time are often more manageable than making a large increase all at once.

Understanding exercise intensity

Knowing how hard to exercise can be difficult after a cardiac event.

During rehabilitation, you may learn to judge exercise intensity using factors such as:

• Breathing
• How easily you can talk
• Your overall feeling of effort
• Heart rate where appropriate
• Your response during and after exercise

The appropriate exercise level depends on your condition and medication, so generic heart-rate targets are not suitable for everyone.

Your rehabilitation programme can provide clearer guidance based on your individual circumstances.

Warming up and cooling down

A cardiac exercise session should usually begin gradually rather than moving straight into more demanding activity.

A warm-up allows your circulation, muscles and heart rate to adjust progressively.

Similarly, exercise should generally finish with a gradual reduction in activity rather than stopping suddenly after harder exercise.

Your rehabilitation programme may include a structured warm-up and cool-down as part of each session.

Managing breathlessness

Some increase in breathing is expected during exercise.

However, there is a difference between normal exercise-related breathlessness and breathlessness that is new, excessive or concerning.

During rehabilitation, you can learn what level of exertion is appropriate for you and when symptoms mean that exercise should be reduced or stopped.

If your usual level of breathlessness changes significantly, it should be discussed with your cardiac or medical team.

Fatigue after a cardiac event

Feeling tired after a heart problem or surgery can make it difficult to judge how much activity to do.

Too much activity too quickly may leave you exhausted, while prolonged inactivity can make rebuilding fitness more difficult.

A gradual programme can help you find a more manageable balance.

Initially, this may mean spreading physically demanding activities throughout the day rather than trying to complete everything at once.

As your fitness improves, the amount you can manage may gradually increase.

Returning to walking

Walking can provide a simple way of gradually rebuilding fitness.

Your starting point depends on what you can currently manage comfortably.

A walking programme may begin with:

• Short walks
• A comfortable pace
• Level surfaces
• Planned recovery afterwards

Over time, progression may involve:

• Walking for longer
• Increasing pace
• Including gentle slopes
• Walking outdoors
• Building towards longer everyday journeys

The goal is to develop a level of walking that fits into normal life and can be maintained.

Returning to everyday activities

Recovery is not only about formal exercise.

Activities such as:

• Shopping
• Cooking
• Household tasks
• Walking outdoors
• Using stairs
• Caring for family members
• Social activities

all require physical effort.

Cardiac rehabilitation can help you gradually return to these activities rather than focusing only on exercise performed during appointments.

Returning to work

The appropriate time to return to work varies according to your cardiac condition, treatment and the physical demands of your job.

A desk-based role will place different demands on the body from a job involving lifting, prolonged walking or heavy manual work.

Rehabilitation can help rebuild the physical capacity required for your occupation.

A gradual return or temporary adjustment to duties may sometimes be appropriate and should be discussed with your medical and occupational team.

Returning to exercise

If you exercised regularly before your cardiac event, it is understandable to want to return to your previous routine.

This should usually happen progressively.

Your rehabilitation may move from:

• Walking
• Light cardiovascular exercise
• Basic strengthening
• Longer exercise sessions
• Moderate resistance work
• More demanding recreational exercise

The activities that are appropriate depend on your condition, previous fitness and medical guidance.

Some people will eventually return to a high level of activity, while others may need to modify the type or intensity of exercise they perform.

Confidence after a heart problem

A heart attack, surgery or other cardiac event can change the way you think about physical activity.

You may worry that increasing your heart rate or becoming breathless means something is wrong.

This can lead to avoiding exercise even after you have been medically advised that activity is appropriate.

Supervised rehabilitation can provide a controlled environment in which to gradually increase exercise and learn how your body normally responds.

Building confidence is often an important part of returning to an active lifestyle.

Managing better and more difficult days

Recovery does not always progress at exactly the same rate every day.

Sleep, medication, illness and general fatigue may affect how exercise feels.

Your programme can be adjusted when necessary while maintaining a gradual overall progression.

If you become unwell or develop new cardiac symptoms, exercise should not simply be pushed through. Appropriate medical advice may be required before returning to the programme.

Longer-term physical activity

Cardiac rehabilitation is intended to help establish habits that can continue after formal rehabilitation has finished.

Over time, the focus may shift from supervised sessions towards more independent activity.

This might include:

• Regular walking
• Gym exercise
• Cycling
• Swimming where medically appropriate
• Home exercise
• Exercise classes
• Recreational activities

The most useful form of exercise is generally one that is appropriate for your condition and realistic enough to continue.

Lifestyle and wider cardiac rehabilitation

Exercise is one part of cardiac rehabilitation.

Depending on the service and your individual needs, wider cardiac rehabilitation may also involve support or education relating to:

• Heart health
• Medication
• Smoking
• Nutrition
• Stress
• Emotional wellbeing
• Sleep
• Long-term physical activity

Physiotherapy primarily focuses on movement, exercise and physical function while working alongside the wider cardiac team where appropriate.

Working with your cardiac team

Cardiac rehabilitation often involves several healthcare professionals.

Depending on your condition and the service involved, this may include:

• Cardiologists
• Cardiac rehabilitation nurses
• Physiotherapists
• GPs
• Pharmacists
• Dietitians
• Psychologists or wellbeing professionals
• Other relevant members of your healthcare team

Your exercise programme should take account of the medical guidance provided by the professionals managing your heart condition.

When exercise should be stopped

You should not continue exercising through symptoms that could indicate a cardiac problem.

Stop activity and seek appropriate medical advice if you develop symptoms such as:

• New or unusual chest pain, pressure or tightness
• Significant or unexpected shortness of breath
• Feeling faint or losing consciousness
• New or unusual palpitations
• Severe dizziness
• Symptoms that feel significantly different from your normal response to exercise

If symptoms are severe, sudden or suggest a medical emergency, seek urgent medical help.

Your cardiac rehabilitation team may also provide more specific instructions based on your individual condition.

Exercise after changes in your health

If there has been a significant change in your symptoms, medication or medical condition, your existing exercise programme may need to be reviewed.

Examples include:

• New chest symptoms
• Increased breathlessness
• New dizziness
• Significant swelling
• A major change in heart rhythm
• A new hospital admission
• A new cardiac procedure

Do not simply continue progressing exercise without discussing significant changes with the appropriate healthcare professional.

Treatment based on your goals

Recovery means different things to different people.

Your goal may be to:

• Walk further
• Use stairs more comfortably
• Return to work
• Become physically active again
• Return to the gym
• Manage household activities
• Improve strength
• Feel less worried about exercise
• Return to hobbies
• Regain confidence after surgery

Your rehabilitation can be developed around these goals while remaining within the medical guidance appropriate for your condition.

How long does cardiac rehabilitation take?

There is no single rehabilitation timeline that applies to everyone.

The length of the programme depends on factors such as:

• The cardiac condition or procedure
• Your previous fitness
• Other medical conditions
• Your current symptoms
• Your physical ability
• The activities you want to return to

Some people progress relatively quickly, while others require a more gradual programme.

Your rehabilitation should be reviewed as your fitness and confidence improve.
