					Benefits of Exercise for
Patients with Coronary
 Heart Disease (CHD)
   Cardiovascular disease (CVD)is responsible for almost
    one in two of all deaths in the UK and it is the leading
    cause of premature death in both men (40%) and
    women(30%).
   The most common form of CVD is Coronary Heart
    Disease (CHD) which is second only to cancer (all
    types) in terms of mortality rates.
   The number of deaths from CHD in the UK is amongst
    the highest in the world and the most common results
    we see are Myocardial Infarction (commonly known as
    a heart attack) Cardiac Arrest and Angina pain.
   There are four main risk factors to CHD which are
    inactivity, high blood pressure, smoking and
    hyperlipidaemia (high blood fats).
   Other risk factors include obesity, diabetes, gender,
    family history, age, ethnic origin, stress and high
    fibrinogen levels (tendency of the blood to clot).
Benefits of Exercise for Patients
with Coronary Heart Disease (CHD)
With these in mind, the benefits of regular exercise and being more
physically active are;

   Increase in circulation
    Improvement in overall heart health, including increase in
    stroke
   volume and cardiac output
    Decreased blood pressure
    Decreased resting heart rate
    Increased lung function
    Improvement in blood lipid profile
    Less prone to fatigue
    Improvement in overall energy, stamina and endurance
    Increase in muscular endurance and metabolism efficiency
    Weight loss
    Increase in insulin sensitivity/improved diabetes control
In addition exercise and
   physical activity also help;

   Improve confidence, mood
    and sense of well being
   Reduce anxiety and
    depression
   Improve return to work rates
    and leisure activities
   Improve health education
    both for the person also and
    their friends/families
   Increase compliance with
    lifestyle modifications
   Many Primary Care Trusts (PCT) have recognized the benefits of
    Cardiac Rehabilitation (CR) as an integral part of medical
    management and as a means of preventing or limiting the chances of
    further Cardiac Events. CR aims to restore and maintain optimum
    levels of physical, mental and psychological well-being after cardiac
    illness.

   The main aspects of CR are a combination of education, exercise and
    psychosocial support, which are delivered by a multiprofessional team
    consisting of doctors, nurses, dieticians, counselors,
    physiotherapists/occupational therapists psychologists and qualified
    exercise professionals.

   CR usually takes the form of four phases, of which Phases 3 and 4 are
    exercise based, either in a hospital or community based setting.
Those who would benefit from CR
include people who have had;
   Myocardial Infarction (MI)
   Cardiac Arrest (CA)
   Angioplasty
   Stable Angina Pectoris
   Coronary Artery Bypass Graft (CABG)
   Valve replacement
   Heart transplant
   Pacemaker or Defibrillator fitted
   Heart Failure (if deemed eligible)
   The types of exercise
    recommended are a
    mixture of walking, home
    exercises, gym or
    studio/circuit sessions
    and chair based classes.
   In addition gentle
    exercise, Tai Chi,
    Aquafit, Linedancing,
    Pilates or
    Yoga can be undertaken
    in many cases.
All Cardiovascular exercise (CV) should be in three
stages. For example for a one hour exercise session

The Warm-up:
  The warm-up phase is done at the beginning of your
  workout and prepares your body for physical activity. This
  gradual increase in activity encourages active blood flow
  to the working muscles and allows the coronary arteries
  to dilate, ensuring enough blood supply gets to the heart
  itself. It increases heart and respiratory rate, increases
  the overall body tissue temperature and facilitates neural
  transmission for motor unit recruitment. The warm-up
  phase of your workout for CHD should last approximately
  15 minutes.
The Workout:
 This portion of the workout can last from
 15-35 minutes depending on your goals
 and current fitness level. This is the core
 of your CV workout. At this point, you
 should be into your target heart rate
 zone, or if on certain medications, your
 Rate of Perceived Exertion (RPE).
The Cool Down:
 This phase should also last 10 minutes and in
 essence is the opposite of the warm-up. This is
 an important phase of your CV workout and
 should not be overlooked. The cool down
 slowly decreases the workload of the CV
 system and allows a smooth and safe
 transition back to the lower work demand. Be
 sure to include plenty of stretching during your
 cool down phase.
