Cardiovascular Disease: An Overview

Ella Edward

Cardiovascular Disease (CAD), or heart disease, begins when blood vessels become too small or cholesterol builds up in the walls. Blood vessels are the blood vessels that supply oxygen and blood to the heart. CAD usually develops when cholesterol builds up in the walls of the arteries, forming plaques. These plaques weaken blood vessels; reduce blood flow to the heart, or cause inflammation and stiffness of the artery walls. A clot can sometimes block blood flow, causing serious health problems. Blood vessels form a network of blood vessels in the face of the heart that feeds oxygen. If these blood vessels are too small, the heart may not receive enough oxygen to filter the oxygen, especially during labor. CAD can sometimes lead to a heart attack. According to the Centres for Disease Control and Prevention, it is the most common form of heart disease.
