Flexi Says: Atherosclerosis is a chronic inflammatory response that causes swelling and buildup of plaque. As plaque grows, it stiffens and narrows the artery, which reduces the flow of blood through the artery.
Atherosclerosis can lead to heart attacks or strokes.
Most congenital heart defects either obstruct blood flow in the heart or vessels near it or cause blood to flow through the heart in an abnormal pattern, although other defects affecting heart rhythm can also occur.
