Just like the rest of the body parts, the heart is another muscle that needs oxygen and enough blood supply in order to function properly. So when there is not enough, certain conditions will appear that are a main cause of disability. There are many different forms of heart illness. The most frequent cause of heart disease is narrowing or obstruction of the coronary arteries, the blood vessels that provide blood to the heart itself. This is named coronary artery disease and occurs gradually over time. It's the major reason people have heart attacks.
Other types of heart problems can occur to the valves in the heart, or the heart may not pump well and provoke heart failure. Many people are born with heart conditions.
