Chest and Back Pain Caused by CAD – Coronary Artery Disease

But if we look closely over here, we can see that there are arteries leaving aorta in order to supply the heart with fresh oxygenated blood in order to function properly. If one of those arteries has a stenosis, it can cause hard not to function properly because it doesn’t get enough of blood. What helps us distinguish this condition, the coronary artery disease, from other conditions explained here, is that this chest pain produced by a coronary artery stenosis can radiate into the neck, back and arms. These symptoms usually happen when we are physically or emotionally stressed because heart has to pump more blood into our muscles and brain in such situations. Can you recall what causes coronary artery disease?
