What about the signs of this disease? Typical angina may characterize ischemic heart disease, so one should be really careful when facing this condition. After all, it is critical to identify the disease at its early stages to avoid further consequences. Angina is another word for pressure, feeling of being fed up, pain in the throat, irritation of the throat, and numbness. Some people confuse a chest pain supported by angina with heartburn. Neck, back, and upper extremities are three other parts of the body under the risk of Ischemic Heart Disease.
