The majority of people will suffer heart attacks (Dr. A. Abdul Jallel, Personal communication, December 10, 2005). To confirm the disease, patients need to undergo tests like ECG, treadmill, etc., which cost money and time. After heavy expenses and large duration only, they come to know whether they are affected by a heart attack or another disease. To help the people, it is planned to give a suitable solution by an emerging technology called “Neuro-Fuzzy.” The main objective of this chapter is to identify the symptom called “angina,” which is severe chest pain prior to a heart attack. With various symptoms like location of pain, radiation of pain, precipitation of pain, duration of pain, cholesterol, smoking, family history, angina can be diagnosed. After the diagnosis, it is possible to know angina's severity, and based on it, a biopsy is recommended for the affected people.

2. Background Of Angina

Angina is a severe chest pain or discomfort that occurs if there is no enough oxygen-rich blood to the area of the heart muscle. It can be felt like pressure or squeezing in the chest portion. The pain can also be felt in other portions of the body such as shoulders, arms, neck, jaw, or back. Sometimes angina may be considered as a discomfort due to indigestion.

As per the physician’s statement, angina is not a disease and it is a symptom of an underlying heart problem. It is usually a symptom of Coronary Heart Disease (CHD), a most common type of heart disease in adults. If a waxy substance called plaque builds up on the inner walls of the coronary arteries, there is a possibility of the symptom of CHD. The coronary arteries do the duty of carrying oxygen-rich blood to the heart.
