The prevalence of chronic heart failure is increasing, and increases with increasing age. Major symptoms include breathlessness and restricted activities of daily living due to reduced functional capacity, which in turn affects quality of life. Exercise training has been shown to be effective in patients with coronary heart disease and has been proposed as an intervention to improve exercise tolerance in patients with heart failure. ⋯ Exercise training improves exercise capacity and quality of life in patients mild to moderate heart failure in the short term. There is currently no information regarding the effect of exercise training on clinical outcomes. The findings are based on small-scale trials in patients who are unrepresentative of the total population of patients with heart failure. Other groups (more severe patients, the elderly, women) may also benefit. Large-scale pragmatic trials of exercise training of longer duration, recruiting a wider spectrum of patients are needed to address these issues.

This is the protocol for a review and there is no abstract. The objectives are as follows: To determine the effects, both harmful and beneficial of aspirin in the primary prevention of coronary heart disease. ⋯ Are the effects of aspirin, be they harmful or beneficial, affected by underlying risk of CHD? Do the major adverse effects of Aspirin ever outweigh its benefit and is this balance affected by underlying CHD risk?
