Coronary Artery DiseaseThe heart is a structurally equipped and well-functioning muscle, which sustains life. Healthy coronary arteries are clean, smooth, flexible and can expand to respond to the need of the heart for more oxygen. But faulty, fatty diet, and perhaps infection, can injure the functioning of the arteries. Coronary artery disease can develop. It begins with atherosclerosis or the accumulation of fatty substances. It can progress to angina or a heart attack. The disease affects other body systems (De Milto, 2001; American Heart Association 2007).
It is the leading cause of death in both sexes in the United States at one in every 4.8 (American Heart Association, 2007). Every 29 minutes, an American will have a heart attack and every minute, one will die of it. Many have silent coronary disease, which can lead to sudden death (American Heart Association).
Various treatments have been devised, such as antibiotics, statins and a regimen of work and social support (Barry, 2006; Hemingway, 1999; USA Today, 2006; Tarbutton & Mitra, 2007). High level of coronary artery calcium is said to increase the risk of developing the disease (Women's Health Advisor, 2008). The overall prognosis is said to be bright.
Coronary Artery Disease 2
Normal Aspects
The normal heart is a muscle, which is only a little bigger than a fist (American Heart Association, 2007). It beats 100,000 times a day and pumps approximately 2,000 gallons of blood daily and continuously through the circulatory system. It has two upper and two lower chambers. The upper chambers are the right atrium and the left at

Dark bluish blood is pumped under low pressure by the right ventricle through the pulmonary valve into the pulmonary artery (American Heart Association, 2007). At this point, blood gets fresh oxygen, turns bright red. It then goes back to the left atrium through the pulmonary veins, crosses the mitral valve and goes to the left ventricle. Red oxygen-rich blood is pumped by the left ventricle through the aortic valve into the aorta. The aorta brings the blood throughout the body (American Heart Association). Healthy coronary arteries are clean, smooth, flexible and able to expand when needed (De Milto, 2001)
Deviations from Normal Anatomy and Physiology
The disease process in arteries generally begins with an injury to their linings and walls (De Milto, 2001). The injury renders them vulnerable to atherosclerosis and blood
Coronary Artery Disease 3 clots (thrombosis). Atherosclerosis is the accumulation of fatty materials in the linings of the arteries. In coronary artery disease, the arteries and blood vessels, which carry oxygen and nutrients to the heart, are restricted or partly blocked. A complete block to the flow results in a heart attack (De Milto).
Effects on Other Organ Systems
The blockage in coronary artery disease limits blood flow from the coronary arteries to the heart (De Milto, 2001). The heart has to work harder to produce more needed oxygen. The arteries then expand. If they cannot, the heart is deprived of oxygen and results in myocardial ischemia. If the block is limited,… READ MORE
