Top causes of angina
Angina is a discomfort in the chest area due to the reduced flow of blood to the heart muscle. It typically leads to a constricted, heavy feeling in the chest and may spread to the neck, jaw, torso, and left arm. There are several reasons why angina occurs in a patient. All the reasons are indicative of coronary artery disease. What causes angina? The heart muscle requires a steady supply of oxygen for the body to survive. Arteries leading to the heart muscle carry oxygen-rich blood to the heart. The problem happens when there is a reduced flow of blood. This occurs when the arteries are narrowed or hardened. Fat deposits or plaque on the arteries can cause this narrowing. This is called atherosclerosis. A person with fat deposits in their arteries will not have angina solely due to the fact that angina is a condition of the low supply of oxygen to the heart. So while the body requires lesser oxygen, say while resting or sleeping, it will get on by with the low oxygen available to the heart. It is when physical exertion takes place that the heart requires a good supply of oxygen, and angina typically occurs.
