Definition Of Coronary Artery Disease

Coronary heart disease: Coronary heart disease is the build-up of plaque such as cholesterol and other fatty substances within the coronary arteries causing a reduced or no supply of oxygen to the heart. The process of plaque lining the coronary arteries is called arteriosclerosis. Coronary heart disease can be caused and triggered by many different factors. These

Similar to other diseases coronary heart disease affects thousands of people. The disease affects the heart in that it causes a waxy substance called plaque where it builds up inside of the coronary arteries. These arteries supply oxygen-rich blood to the heart muscle. When a person has coronary heart disease the hardened arteries restrict blood flow, which means that the heart cannot receive enough oxygenated blood, especially when it beats quickly during physical exertion or stress. This can cause chest pain and shortness of breath. However, if the artery is completely blocked, a heart attack can occur. Lack of oxygen during a heart attack causes damage as the heart muscle dies and is replaced with scar tissue. If damage is severe, the heart

The main effect that Coronary heart disease has on a person’s body is interruption of blood flow to the heart. It blocks the blood flow in many different ways. One way this disease does this is building up plaque in the arteries leading to the heart. This plaque hardens making a wall. This wall does not allow any blood or oxygen to the heart. Another way that Coronary Heart Disease stops blood flow to the heart is by narrowing the small blood vessels that provide blood and oxygen.

Coronary artery disease (CAD) is caused by reduced blood flow in the coronary arteries. This subsequently leads to reduced oxygenation to the myocardium, resulting in transient ischemia or angina. CAD may cause permanent damage to myocardial cells or infarction. The left ventricle of the heart is most susceptible to CAD.

Diabetes. Patients with diabetes carry an increased risk of coronary artery disease due to the similarity of the high blood pressure.

According to Teague, author of the textbook Your Health Today, “An estimated 16.3 million Americans are living with CHD [and] those who survive a heart attack are often left with damaged hearts and significantly altered lives” (316). Clearly, coronary heart disease affects numerous families and individuals and it is a worldwide disease. So, what causes coronary heart disease? As a coronary artery becomes blocked with plaque, a condition called ischemia is developed. Ischemia condition refers to the lack of oxygen supply and nutrients in the heart muscle due to a narrowed or blocked artery. However, if the artery is completely blocked, an individual has a myocardial infarction; which is the insufficient blood flow to the heart muscle, in simpler terms, a heart attack. The blockage and narrowing of an artery may be the result of plaque that has broken loose or a formation of a blood clot, which can cause coronary thrombosis, which may cause sudden death. Ultimately, a heart attack occurs when during a lack of oxygen blood flow to the heart muscle is reduced or cut off due to the blockage of arteries with

According to the Mayo Clinic Website, the disease occurs when the major blood vessels that are responsible for supplying an individual’s heart with blood, nourishment and oxygen is damaged (Mayo Clinic, 2016). The cholesterol that is in your body time will cause a build up of plaque in your arteries which will eventually cause blockage. The build up of plaque is also associated with the inflammation of arteries. Some symptoms that are coupled with Coronary Artery Disease is the presence of chest tightness, nausea, weakness and fatigue (Eastwood, Johnson, Rutledge, Bittner, Whittaker, Krantz, Cornell, Eteiba, Handberg, Vido and Bairey, 2013). As well as Angina which is the chest pain; it is described as a sensation of pressure or tightness a person experiences. Many people experience that kind of pain in the middle or on the left side of the chest (Mayo Clinic, 2016). Angina is usually triggered by emotional or physical stress. Sometimes females can experience Angina differently; females will feel the pain but it will disappear quickly. They will feel the pain in their necks, arm and back. Accompanied with Angina, a person will experience Shortness of breath due to the fact that the heart can not pump enough blood according to a person’s needs which will result in immense fatigue and exertion. Heart attack is a serious symptom that a person can experience can also end up killing them. Once the Coronary Artery is completely blocked by the numerous amount of plaque buildup a heart attack will occur. Some signs of a heart attack can include an awful amount of pressure in an individual’s chest and pain that is in the arm of shoulder. Usually people might experience shortness of breath and sweating. When the signs of heart attacks are shown in women they are not as clear. Sometimes they will experience neck and jaw pain. Sometimes, heart attacks do not have symptoms but

CHD is a disease in which a waxy substance called plaque builds up inside ones coronary arteries. Coronary arteries supply oxygen filled blood to the heart muscle. The thickened walls of the arteries slow down blood flow and make the heart have to work harder to get blood to the places it’s needed throughout the body. Most times the symptoms of CHD are very noticeable, but in some cases one can have the disease and not even know it. Symptoms of CHD include: chest pain, shortness of breath, fatigue, and general weakness.

Coronary Heart disease is a disease in which a waxy substance called plaque builds up inside the coronary arteries.The arteries supply oxygen rich blood to your heart muscle.What cause (CAD) is smoking,Fats and cholesterol in the blood,High blood pressure,insulin resistance or diabetes,Blood vessel inflammation.How does the disease get treated, it get treated by taking medications,sugical procedures,regular check ups.

Coronary artery disease happens when blood cannot flow properly through the arteries due to the accumulation of plaque along the artery walls. This causes pressure on the heart, which cannot get all of the blood, oxygen and important nutrients that is needed. As plaque builds up and the arteries narrow, chest pain and other symptoms arise. Extensive exposure to plaque build up may weaken the heart and cause heart failure. When the blockage from plaque becomes bad enough, blood may begin to clot from being unable to pass through the arteries, resulting in a complete blockage. This kind of blockage can produce a heart attack.

What is it? In the coronary circulation, the vessels that supply oxygen-rich blood to the myocardium are known as coronary arteries.Coronary artery disease ( also called CAD or coronary heart disease) is caused by a thickening of the inside walls of the coronary arteries. This thickening is called atherosclerosis. Atherosclerosis is the usual cause of heart attack, strokes and peripheral vascular disease. Together they are called cardiovascular disease. Cardiovascular disease is classified as the number one killer in the United

Coronary artery disease (CAD) is defined as any type of vascular disorder that either narrows or occludes the coronary arteries. Atherosclerosis is the most common cause of coronary obstruction. Coronary artery disease causes ischemia. Moreover, persistent ischemia results in acute coronary syndromes such an infarction. An infarction can result in a heart attack. The rate of incidence is the U.S. is that, CAD results in more that 500,000 myocardial infarctions per year and is the cause of one-third of all deaths. A risk factor for CAD is hyperlipidemia, which can develop due to a high dietary fat intake. Another risk factor is hypertension or elevated blood pressure. Cigarette smoking, diabetes mellitus, genetic predisposition, and obesity

Although we may not be able to control all the contributing factors that may lead to heart attacks like family history and aging, there are other factors that are completely in our power to change. We can control the behavior that leads to obesity, along with refrain from smoking and heavy drinking. Regular exercise, a good diet and getting plenty of rest and controlling our blood pressure are a few good things we can do to reduce the risk factors dramatically.

The heart is the most important muscle in the human body. It is about the size of the owner's fist. The heart is the pump that drives the whole circulatory system. It receives and propels blood, rhythmically contracting with every heartbeat and forcing the blood through a system of arteries veins and capillaries, where it eventually reaches cells and tissues. Blood contains essential nutrients, oxygen, hormones and enzymes. Without the heart pumping blood, cells would not receive any nutrition and would die, thus in order to sustain life one must have a heartbeat.

The heart is a large muscular organ and its main job is to circulate blood all around the body. The heart consists of three outer layers: the pericardium is the tough outer protective layer, the myocardium which is the middle muscular layer and then finally the endocardium which is a smooth membrane lining. The heart has four chambers within it. The left/right atria and the left/right ventricles. Between these chambers there are valves which control the blood flow between the chambers. The blood flows through the heart from right to left- The right atrium receives deoxygenated blood from both the superior (top half of body) and the inferior
