Coronary artery disease occurs when heart’s blood supply is blocked or interrupted by building up of atheroma in the coronary arteries. They become narrow and blood supply to the heart muscle is restricted. This can cause angina. If coronary artery becomes completely blocked it can cause heart attack. This is a medical emergency. Angina occurs when heart muscles need more blood than it is getting such as during physical activity or during strong emotions. Angina is not a disease but a symptom and warning sign of heart disease. A patient with angina may complain of episodes of chest discomfort, usually described as heaviness, pressure, squeezing, smothering, or choking and only rarely as frank pain. Angina is considered to be ‘chronic’ and ‘stable’ when symptoms are present for at least two months, without changes in severity, character or triggering circumstances. Chronic stable angina has a consistent duration and severity and is provoked by a predictable level of exertion. It can also be provoked by emotional stress. An imbalance between myocardial oxygen supply and metabolic oxygen demand causes the symptoms of angina pectoris and represents a major therapeutic target.                  

       In Ayurveda Literature, the heart is the root of the rasavaha srotas and vitiation of rasa dhatu by morbid dosha leads to heart disease. The etiological factors which lead to vitiation of this srotas include- Aharaja- Guru, Sheeta, Atisnigdham, Atimatram, Samashanam. Vagbhata has mentioned that the dietary habits samashana, vishamashana and adhyashana cause serious fatal diseases including the hridroga. Due to the Agnimandhya, the presence of Ama renders the body metabolically slow and sluggish along with varying degree of blockage of the channels of the body at different levels from gross to molecular level. During its sojourn in these channels, it tends to adhere to the walls thereby narrowing the passages or causes srotorodha. Increased impermeability and sluggishness of the body channels or rasavaha srotas increases resistance and compel to pump blood more vigorously and the burden on the heart.  There are 5 types of Hridroga namely Vataja hridroga, Pittaja hridroga, Kaphaja hridroga, Tridoshaja hridroga and Krimija hridroga. The etiopathogenesis of chronic angina pectoris has in order resembled any existing Kaphaja Hridroga entity in particular.

NEED OF STUDY

         Despite important advancements in the pharmacotherapy of Chronic Stable Angina Pectoris, the actual percent reduction in mortality associated with the use of modern pharmacological agents has been relatively unpretentious. Moreover, the available pharmacological agents are also not free from various adverse effects. Hence there is an immense requirement of certain Ayurvedic drugs which can increase efficiency and performance of compromised heart for healthy living in a natural way with least possible adverse effects.
