coronary arteries
Heart bypass surgery is performed when one has a blockage in one or more of their coronary arteries. When one or more coronary arteries are blocked, the heart does not receive enough oxygen and the patient may have chest pain or damage to the heart.
It is called "angina" or more specifically "angina pectoris" (Latin a strangling of the chest). It is caused by the lack of oxygen to the heart muscles, the blood flow in the cardiac arteries being blocked, typically by atherosclerosis.
Pleuritic refers to chest pain. Pleurisy is inflammation of the lining of the lungs. Someone with pleurisy will likely have pleuritic chest pain.
I think the primary reason is blocked arteries feeding your heart, but other things could cause this. You need to see a doctor right away.
the arteries become narrowed and the flow of blood and oxygen is blocked. Blockages can cause pain in the chest (angina) and eventually, when the blood vessels are occluded (closed up), a heart attack.
relieves chest pain and reduces risk of a heart attack by using a different vein or artery for blood circulation in the heart. The current vien would be blocked by fatty deposits therefore requiring a bypass.

If your chest hurts when you run, and you suspect that something could be blocked in your chest, it is advised that you get checked by your doctor.
Arteriosclerosis
The arteries that are located throughout your body are in the chest are and near the heart where the most important arteries lye, these arteries help digest the food and provide blood and oxygen in your body.
Smoking is a major cause of atherosclerosis " a buildup of fatty substances in the arteries. Atherosclerosis occurs when the normal lining of the arteries deteriorates, the walls of the arteries thicken and deposits of fat and plaque block the flow of blood through the arteries. In coronary artery disease, the arteries that supply blood to the heart become severely narrowed, decreasing the supply of oxygen-rich blood to the heart, especially during times of increased activity. Extra strain on the heart may result in chest pain and other symptoms. When one or more of the coronary arteries are completely blocked, a heart attack may occur.
