IMAGES Heart Disease See a detailed medical illustration of the heart plus our entire medical gallery of human anatomy and physiology See Images Other topics, such as myocarditis, heart valve problems, and congenital heart defects will not be covered. This is called a heart attack or myocardial infarction (myo=muscle + cardia=heart + infarction= tissue death).Ĭardiovascular disease, for this article, will be limited to describing the spectrum of atherosclerosis or hardening of the arteries that ranges from a minimal blockage that may produce no symptoms to complete obstruction that presents as a myocardial infarction. This causes a piece of the heart muscle to die. Should one of the coronary arteries become completely blocked - usually due to a plaque that ruptures and causes a blood clot to form - blood supply to part of the heart may be lost. The classic symptoms of chest pain or pressure and shortness of breath that often spreads to the shoulders, arms, and/or neck due to atherosclerotic heart disease (ASHD) or coronary artery disease ( CAD) are called angina. Should the arteries continue to narrow, it may take less activity to stress the heart and provoke symptoms. This can cause the heart muscle to ache like any other muscle in the body. When one or more coronary arteries narrow, it may make it difficult for adequate blood to reach the heart, especially during exercise. These arteries originate from the base of the aorta (the major blood vessel that carries oxygenated blood from the heart) and then branch out along the surface of the heart. Not only does the heart pump blood to the rest of the body, but it also pumps blood to itself via the coronary arteries. It needs an adequate blood supply to provide oxygen so that the muscle can contract and pump blood to the rest of the body.
The heart is like any other muscle in the body. In some people, surgery or other procedures might be needed.Many times lifestyle changes such as eating a heart-healthy diet, exercising regularly, stopping smoking, and controlling high blood pressure, high cholesterol, and diabetes may limit the artery narrowing. Treatment for coronary heart disease depends upon its severity.EKG blood tests and tests to image the arteries and heart muscle confirm the diagnosis. Coronary heart disease is initially diagnosed by patient history and physical examination.Some may have signs and symptoms of indigestion or exercise intolerance where they cannot perform activities that they normally once could. Not all people with coronary artery disease have chest pain as a symptom.Chest pain ( angina) - This pain may radiate or move to the arm, neck, or back.Classic signs and symptoms of coronary heart disease may include:.That part of the heart muscle that is denied blood supply starts to die. A heart attack occurs when a plaque ruptures and forms a clot in the artery causing a complete blockage.Over time, this buildup of plaque may partially block the artery and decrease blood flow through it. Coronary arteries supply blood to the heart muscle and coronary artery disease occurs when there is a buildup of cholesterol plaque inside the artery walls.Coronary artery disease is the most common type of heart disease in the US.
