First, the definition of the disease: Coronary artery disease (CAD), also known as Coronary Micro vascularcoronary microvascular Disease it is First the definition of the disease: Coronary artery disease (CAD) also known as Coronary Micro vascular Disease it, is the most common type of heart disease. CAD happens when the arteries that supply blood to the heart muscle become hardened and narrowed. This is due to the buildup of cholesterol and other material, called plaque, on their inner walls. This buildup is called atherosclerosis. As it growsthe disease progresses, less blood canis able to flow through the arteries. Asand as a result, the heart muscle can't get the blood or oxygen it needs. This can lead to chest pain (angina) or a heart attack. Most heart attacks happen when a blood clot suddenly cuts off the hearts'heart's blood supply, causing permanent heart damage.
Over time, CAD can also weaken the heart muscle and contribute to heart failure and arrhythmias. Heart failure means the
inability of the heart can'tto adequately pump blood well to the rest of the body. Arrhythmias are changes in the normal beating rhythm of the heart.
The heart is a large muscular organ with the very important job of circulating blood through the blood vessels to the body. Located in the center of the chest, the heart is the
hardest workinghardest-working muscle in the human body; it is always working, even while we are sleeping. The heart and blood vessels together make up the body's cardiovascular system, and arewhich is vital to supplying the body with the necessary oxygen and nutrients needed to survive. When you breathe, your lungs take in oxygen. The; the heart pumps blood to the lungs to pick up that oxygen, and then it pumps oxygenated blood through the body to deliver that oxygen everywhere it is needed.
