Effect of Moderate Intensity of Aerobic Exercise Programme on Exercise Tolerance Capacity of Stable Angina Patients

Stable angina is defined as a short duration chest and/or arm discomfort that shows no change in the past 60 days in frequency, duration or precipitating cause. Most often pain duration is less than 10 minutes and rarely up to 15 minutes. The mild to moderate discomfort is relieved within 1 to 10 minutes by cessation of the particular precipitating activity or use of sublingual nitroglycerine (Khan, 2006). Most patients with stable angina will be at increased risk of subsequent cardiovascular events or death, the assessment of a patient‘s absolute risk of subsequent cardiovascular events or death should be based on assessment of all of his risk factors as well as modifiable risk factors include age, sex, presence of diabetes, and family history of premature coronary heart disease. Exercise training is an effective method of reducing episodes of angina in people with stable angina. Chronic low intensity aerobic exercise trains the cardiovascular system and the skeletal muscles to become more efficient which means that one can exercise at higher levels of intensity without experiencing angina. A program of aerobic exercise has many benefits in addition to reducing episodes of angina. The physiological changes both in exercising skeletal muscle and the myocardium play a role in the symptomatic improvements and increased maximal work capacities in individual with coronary artery disease after regular aerobic exercise (May and Nagle, 1984).
