Cardiac Rehabilitation
Eve ScarleSenior Physiotherapist and
Lecturer in Exercise and Health Sciences
Aims of the session
1. Explanation of coronary heart disease and cardiac rehabilitation
2. Rationale for the use of physical activity in cardiac rehabilitation
3. Exercise prescription for Phase IV cardiac rehabilitation
4. Professional development opportunities in CR.
Group Task Plan a short exercise regime you may use for a 50
year old patient who has suffered a heart attack 4 months ago. Consider the; Frequency Intensity Duration Progression Type of exercise that you would prescribe for this
patient Are there any types of activity you think should be avoided?
Cardiovascular Disease (CVD)
CVD accounts for one of two of all deaths in UK accounting for approximately 238,000 deaths in 2002
Leading cause of premature death in both men and women.
CHD most common form of CVD and is responsible for 60% of all deaths from CVD.
Our Healthier Nation target – CHD and Stroke - reduce death rate in
people under 75 years by two fifths
Coronary Heart Disease (CHD)
♥ Refers to the deposition of fatty substances in the lumen of the coronary arteries
♥ This can start as early as the teenage years
♥ Only when the artery is ~ 70% occluded do symptoms start to appear
♥ Symptoms may appear as angina or a myocardial infarction (MI)
♥ Angina occurs when demand for oxygen does not meet the supply as the coronary arteries are narrowed
Atherosclerosis is the build up of fatty and fibrous material (atheroma) on the inside surfaces of arteries
Atherosclerosis
Atherosclerosis
Angina A symptom of CHD Occurs during ischaemia when supply of
oxygen does not meet the demand for oxygen
When do you think individuals may get angina symptoms?
What will the symptoms be?
Stable Angina
Exertion
Stress
Extreme temperatures
After a heavy meal
Chest pain /tightness/discomfort
Burning/dull sensation
Pain/heavy feeling in left arm or both
Discomfort in throat, jaw or abdomen
Short of breath on exertion
Myocardial Infarction (Heart Attack)
♥ Occurs when a fatty plaque becomes unstable and ruptures
♥ This causes a blood clot to form stopping blood getting any further
♥ This leads to areas of myocardial ischaemia which if it persist can lead to tissue damage
♥ Needs prompt management to limit damage and reduce complications
Coronary Artery Bypass Graft
♥ Where narrowing occurs in multiple areas
♥ Veins and arteries are harvested from elsewhere in the body and used to bypass the narrowing
♥ This involves open heart surgery, being on the bypass machine and a prolonged recovery period
Coronary Angioplasty
♥ Procedure done under local anaesthetic
♥ Catheter passed from the groin up to the aorta
♥ Then pass into the narrowed area and inflate a small balloon to squash plaque into the artery wall
♥ Small cylindrical stents can be left in place to hold the artery open
Aims of Cardiac Rehabilitation
‘To promote physical, psychological and emotional recovery, enabling patients to
achieve and maintain better health, with a reduced risk of death from continuing heart
disease.’
(Effective Health Care, 1998)
History of Cardiac Rehabilitation
♥ Cardiac rehab first started in the 1960s when the benefits of active mobilisation were recognised (Kavanagh et al, 1973).
♥ Disease processes in CHD may be slowed or even reversed by the instigation of lifestyle modification (Ornish et al, 1990 and 1998; Berlardinelli et al, 2001).
♥ National Service Framework for CHD (DoH, 2000) sets national standards for CHD management
What exactly is Cardiac Rehabilitation?
What is it? Combination of exercise, education
and counselling
How long does it last? Varies across the country
Where does it occur? Hospital and community-based
What exactly is Cardiac Rehabilitation?
Who is it delivered by?
Delivered by a ,multi-disciplinary team which can consists of:-
Counsellor Nurse Occupational therapist Physiotherapist Psychologist Exercise physiologist Phase IV instructor
Phases of CR
Phase I In Hospital
Phase II Immediate post discharge period
Phase III Out-patient programme
Phase IV Ongoing maintenance phase
Phase I
♥ Acute phase in hospital ♥ A member of the cardiac team provides
specific information on:- heart disease management of chest pain how to handle serious cardiac symptoms gradual increase in PA use of medication risk factor modification and lifestyle changes feelings and relationships driving, insurance and airline travel.
Phase II
♥ Patient at home under care of GP, lasts 2 - 6 weeks.
♥ Often neglected phase of rehab.♥ Ideal time to reinforce important
messages and behaviour change.♥ Telephone advice service♥ Home visiting
Phase III♥ Consists of exercise, health education,
risk factor modification, relaxation and stress management, and occupational counselling.
♥ Can take place in hospital or community ♥ Exercise and education for up to 12
weeks.♥ Exercise aim is to educate individuals
on safe and effective ways to make exercise a part of their lives
Phase IV
♥ Community-based CR♥ Little community provision for this group
and previous structured sessions make it difficult for patients to exercise independently.
♥ British Association of Cardiac Rehabilitation (BACR) developed protocol for CHD patients to move from Phase III to Phase IV.
Phase IV
♥ Aims of Phase IV:- provide regular supervised CV training
sessions establish individualised ex. prescription for
independent activity. review participants progress over time (or
regression) and amend prescription accordingly.
offer general advice and support in lifestyle changes
encourage independence , self help and self motivation.
Phase IV♥ Class format could take the following:-
integration of individuals with CHD into mainstream classes
specialist phase IV classes one to one training
♥ What are the disadvantages/advantages of these different sessions? Write down your ideas
Advantages Disadvantages
Mainstream Class
*Get back to normal life*Integration
*Not geared up to heart patients*? correct exercise
Phase IV Class
*Social support*Regular exercise groups*Specifically for heart patients
*Reinforce message that something is wrong with you*Does the exercise have progressions
One-to-one training
*Individual advice*Easy to progress exercise
*No social support for other patients
Classroom Task
Exercise Prescription for Phase IV
Inclusion criteria (BACR, 2003): Post Myocardial infarction Post coronary artery bypass graft (CABG) Post angioplasty (with or without pre cardiac
event) Post transplant Post valve replacement Stable angina Permanent pacemaker Implanted defibrillator
Also partners/spouses encouraged to attend.
Phase IV Exercise Prescription
Frequency At least 3 times a week
Intensity 60-80% of max HR
13-15/3-5 RPE Time 20-60 mins
Type Aerobic endurance training
Session components – Warm-up
♥ Content♥ Pulse raising and mobility♥ Preparatory stretching.
♥ Rationale♥ Gradual, progressive w/up extends ischaemic and
angina threshold. Too strenuous can lead to arrhythmias and a reduced ejection fraction.
♥ Duration♥ 15 mins. minimum.
♥ Intensity♥ HR to within 20 bpm of training HR or RPE no higher
than 10-11 on 6-20 scale.
Interval Training Approach Effective in early stages of recovery
and those who are deconditioned Allows a greater total duration of
exercise per session Allows easy management of a group
of individuals of differing abilities
Ultimate AimTo achieve continuous
cardiovascular work for 20- 60 minutes
Active Recovery Low intensity activity e.g. walking at a
slower speed Alternative activity e.g. muscular
strength work (with feet moving)
Can fit with different activities e.g. circuit programme, gym, walking, home programme
Session components –Cool down
Content Recovery period, slow walking, gentle movements, large
muscle groups, stretching. Rationale
Older adults take longer to return to pre-exercise states due to aging and baroreceptor changes.
Increased risk of arrhythmias with increased intensity and lack of cool down
Duration 10 mins.
Intensity Reduced, aim to return to pre-exercise state
Session components – MSE Content
Floor based has to be done out of main circuit Could Integrate standing MSE as active recovery in the
aerobic section. Rationale
Increases strength and endurance of specific muscle groups
Duration Dependent on location within class
Intensity Low resistance high repetitions, 1 x10-15 reps 8-10 exercises
Professional development opportunities in CR
British Association for CardiacBritish Association for CardiacRehabilitation (BACR) Rehabilitation (BACR)
♥ BACR - founded in 1993, national organisation for professional involved in CR.
♥ Phase IV Exercise Instructor Training Module
Evidence of Benefit of CR
♥ Improved survival (25-31% reduction) (1,2)
♥ Improved functional capacity and VO2MAX (3)
♥ Reduced angina (4)
♥ Improved lipid profiles♥ Lowers BP (5)
♥ Reduced anxiety and depression (6)
♥ Increased confidence and well being (7)
♥ Improved return to work and leisure (8)
♥ Effect of improved health education in family and friends
♥ Improved compliance with lifestyle modification
Rationale for the use of PA in CR
Jolliffe et al., 2001; Enhanced coronary blood flow Increased angina threshold Improved peripheral muscle
metabolism efficiency Improved quality of life.
