CAD occurs when the arteries supplying blood to your heart muscle become narrowed and hardened due to plaque buildup.
During physical exertion, your heart has to work harder and therefore demands more oxygen-rich blood. If your coronary arteries are narrowed, they can’t deliver enough blood to meet this increased demand. This mismatch between supply and demand causes the heart muscle to
