Yoga may have a profound and positive impact on secondary prevention and improvement on overall conditions in individuals with coronary heart disease, some studies suggested.

Coronary artery disease is a medical condition caused by accumulation of plaques that block arteries in supply blood nutrients and oxygen to the heart. Most cases of the disease is associated to atherosclerosis, the condition of hardening of the arteries.

According to statistic, coronary artery disease is the most common type of heart disease that cause death of over  370,000 people every years, representing 28% of all death in the United States.

Sadly, according to the Centers For Disease Control and Prevention, approximately, 735,000 Americans have a heart attack each year.

What cause plaques building up on the arterial are debatable. However, researchers suggested that Western diet is associated to significantly increased risk of coronary artery disease.

Dr. Venegas-Pino DE in the classification of the effect of diet on heart diseases said,” the western-diet-fed male ApoE-/-:Ins2+/Akita mouse, with profound cardiovascular disease involving extensive atherosclerosis, coronary artery disease and myocardial infarct resulting in shortened lifespan(4)”.

Most common symptoms of coronary artery disease is angina, the condition characterized by chest pain or discomfort and shortness of breath as a result of weakening of heart muscle which can not pump enough blood to the body needs.

Over time, prolonged weakened heart muscle can lead to complications of heart failure, irregular heartbeat, or arrhythmia.

Yoga, the ancient practice for harmonized external and internal body well being, through breath control, meditation, bodily movement and gesture….. has been well known for people in Western world and some parts in Asia.

In a total of 80 stable CAD patients below 65 years of age of both sexes selected and randomized into two groups of 40 each. yoga Group I with for 3 months yoga lessons consisted yogic postures, pranayama breathing exercises, dietary modification, and holistic teaching along with their conventional medicine while Group II treated only on conventional medicine after 3 months, researchers found that,

*Groups attended yoga lessons expresses statistically significant improvements slow vital capacity, forced vital capacity, peak expiratory flow rate, maximum voluntary ventilation, and diffusion factor/ transfer factor of lung for carbon monoxide in compared to group II.

* The lung function in forced respiratory volume in 1(st) sec (FEV1), and FEV1 % also shows a trend toward improvement although not statistically significant in also compared to conventional treatment group.

Dr, Yadav A, the led authors after the experiment said, “Yoga regimen was found to improve lung functions and diffusion capacity in CAD patients besides improving cardiovascular functions”.

These results suggested that yoga postures and meditation have a profound effect in relaxed arterial muscle to allow more blood to flow through by reduced stress which causes the muscle wall  tightening.

Furthermore, yoga posture and breathing technique also improved the lung muscle in absorption of more oxygen for the blood.

In support of the above analysis, Dr. Pal A, and colleagues conducted a study of 258 patients from the Department of Cardiology in Chhatrapati Shahuji Maharaj Medical University diagnosed with coronary artery disease randomly divided into 2 groups, the yoga group and the non-yoga group with 129 in each group, yoga attendees after 35-40 min/day, 5 days a week over a period of 18 months displayed a statistically significant reduction in body mass index, waist circumference, systolic and diastolic blood pressure, and heart rate (P < 0.05).

The relaxation to allow more blood to provide nutrients and oxygen to the body needs may also result in reduced the blood pressure, thus lowering the heart rate.

After taking into account of other risk factors, researchers suggested that yoga therapy expressed a significant effect on secondary prevention of mortality and morbidity and health-related quality of life of individuals with coronary heart disease,
