Cardiac Rehabilitation and Fitness - What is the evidence ?

---

Medical Progress 

Progress in medication as well as treatment of cardiovascular disease in recent years has been impressive. As a consequence more men and women now survive acute events but with a considerably heavier burden of chronic conditions and clinical need. 

Recommendation

Cardiac rehabilitation (CR) has the highest level of recommendation (Class I) of all national and international cardiology and health societies.

- European Society of Cardiology (ESC).
- American Heart Association (AHA).
- American College of Cardiology (ACC).
- World Health Organisation (WHO).

And is endorsed by the Cardiac Society of Australia and New Zealand (CSANZ) and the New Zealand Heart Foundation. 

Aim

Cardiac patients after an acute event and/or with chronic heart disease deserve special attention to restore their quality of life, to maintain or improve functional capacity and to prevent subsequent coronary events, hospitalisations, and death from cardiac causes [ESC guideline].

Benefits

Cardiac Rehabilitation (CR) is associated with a 20% - 35% reduction in mortality in persons with coronary artery disease, particularly after myocardial infarction and after aortocoronary bypass surgery, but also after PCI for stable coronary disease. This benefit is thought to be mediated by several factors, including the benefits of exercise training, psychological benefits of group support and counseling, improved adherence to preventive therapies, and improved control of cardiovascular risk factors.

My risk of heart disease

For what condition is cardiac rehabilitation recommended ?

​The most sustainable benefit is achieved in conditions associated with coronary artery disease and heart failure:

Acute and stable Coronary Artery Disease
Stent Implantation
Coronary artery bypass surgery (CABG)
​Chronic Heart Failure
​Diabetes Mellitus
High Blood Pressure
​Atrial Fibrillation

How much Cardiac Rehabilitation do I need ?
​

This varies considerably between participants and requires individual assessment. 
​In a US study [Hammill et al.] participants of 36 sessions (12 weeks) had a 47% lower risk of death and a 31% lower risk of a heart attack compared to participants with only 1 session. 
​
Recently published data from 2016 showed that by continuous improvement of exercise capacity the risk of dying from a heart attack can be lowered.
