CAD stands for coronary artery disease, which is when the coronary arterial lumen becomes narrowed due to the build up of atherosclerotic plaques. Atherosclerosis develops over several stages:…
Coronary artery disease is the condition of the narrowing of the arteries that supply oxygen and blood to the myocardium (heart muscle). The narrowing is caused by a substance called plaque, which contains deposits of fat that cause blockages within the arteries. The blocked arteries then become hardened (atherosclerosis) and narrow, not allowing adequate…
Coronary artery disease is one of the most prominent forms of heart disease. It occurs when the coronary arteries that supply the heart blood become narrowed, and eventually occluded. This narrowing typically takes place because of plaque build up due to cholesterol and other fatty substances being ingested, also called atherosclerosis. This thickening of the artery wall can take many years, eventually completely inhibiting blood flow. Because the blood flow has stopped, little oxygen gets to the heart, and the myocardial cells therefore die. This is when a heart attack ensues, also called a myocardial infarction.…
Atherosclerosis is a chronic disease which is caused by the thickening of the artery wall as a result of the accumulation of plaques which are made up of calcium and fatty materials such as cholesterol particles (lipoproteins) and triglyceride in the innermost layer of the endothelium of the large and medium sized arteries. The disease disrupts the flow of blood around the body, posing serious cardiovascular complications. Atherosclerosis begins as soft deposits of fat that hardens with age.…
In a coronary calcium scoring test, CT scans are taken of the heart to detect the amount of plaque on your coronary artery walls, which can block blood flow to your heart and be an indicator of cardiovascular disease.…
1. Coronary Artery Disease is briefly described as a plaque blockage cutting off blood flow to your heart. Cholesterol deposits slowly, over decades, build up in the vessel wall and cause a decrease in blood flow. A patient with decreased blood flow to the heart may have angina, shortness of breath, and in some cases a myocardial infarction.…
CAD is thought to begin with damage or injury to the intimal layer of coronary artery, sometimes as early as childhood. The damage may be caused by various factors, including: smoking, hypertension, hypercholestromia, diabetes or insulin resistance, radiation therapy to the chest, as used for certain types of cancer, and sedentary lifestyle. Once the intimal layer of coronary artery is damaged, fatty deposits (plaques) made up of cholesterol and other cellular waste products tend to accumulate at the site of injury in a process called atherosclerosis. If the surface of these plaques breaks or ruptures, platelets will clump at the site to try to repair the artery. This clump can block the artery, leading to a heart attack. Recent research has…
Coronary Artery Disease (CAD), is a condition in which plaque builds up inside the coronary arteries. These arteries supply oxygen-rich blood to your heart muscle. This plaque is made up of fat, cholesterol, calcium, and other substances found in the blood. When plaque builds up in the arteries, the condition is called atherosclerosis, the buildup of plaque occurs over many years. Over time, the plaque hardens which causes your coronary arteries to narrow, which limits the amount of oxygen and blood your muscles are supposed to get to function properly. Coronary Artery Disease is the leading cause of death in the United States because of the people’s not so healthy diet, lack of exercise, and tendency to smoke, which are the leading causes of CAD. The symptoms might be very noticeable, or you might not experience anything. Some of the signs and symptom might include angina which causes major chest pain or at least some discomfort or abnormal feeling on your chest. Also, you may feel like your chest is closing up and it will become harder for you to breathe, also may experience pain on your neck, lower back. Fatigue and weakness are also symptoms for this as well along with what was mentioned. For treatment, your doctor will give you specific medications based on how severe your case is, eating habits will need to change, start exercising, and if a smoker, to quit smoking. If you are given medicine by the doctor be sure to take all the medicine don’t stop because you feel better. The reason why one is to take all the medicine is because if not finished it will come back but even worse than it was before. In very extreme cases, a stent placement, minimal invasive heart surgery will be needed in order to survive. Although everyone is different, early detection of CHD generally results in a better outcome. Even though one may be done with treatments one might…
Carotid artery disease is the narrowing (stenosis) or blockage (occlusion) of the carotid arteries. Carotid artery disease is a common problem and a major cause of stroke. Carotid artery disease is caused by atherosclerosis (plaque) Atherosclerosis cannot be prevented, but the progression of the disease…
The best way to prevent CAD is to stop these bad habits such assmoking, eating a lot of fast foods and not exercising.When an individual practices preventionthey are at a much lowerrisk of having heart disease.…
6. Read the information labeled “Limit These Nutrients.” Why is it important to limit Trans fats and Saturated fats? too much will risk certain chronic deceases, like heart disease, some cancers or high blood pressure.…
There are a great number of diseases such as cancer and HIV around the world. However, cardiovascular disease (CVD) is now arousing public attention due to its increasing effect on populations. ‘Cardiovascular disease (CVD) is the name for the group of disorders of heart and blood vessels such as hypertension, coronary heart disease, stroke, and peripheral vascular diseases’ (WHO, 2012). CVD has enormous impacts on health and kills an estimated 17 million individuals worldwide annually (Mandal, 2012). A great amount of research explicitly indicates some causes. The most important factors of CVD are unhealthy lifestyle, tobacco use and alcohol abuse. To avoid suffering from CVD, individuals should engage in regular physical activities, choose a balanced diet, and reduce consumption of tobacco and alcohol. The following assignment will analyze the causes of cardiovascular disease.…
The cardiac muscle of the heart wall depends on a constant flow of blood supply by the coronary arteries. Coronary arteries are blood vessels that arise from the base of the aorta and bring freshly oxygenated blood to the heart muscle. If this supply is restricted, then oxygen and nutrients can’t reach the muscles and the result could be a form of coronary artery disease (CAD). It can also be known as coronary heart diseases (CHD). This form of partial or complete block can be caused by fatty deposits, blood clots, or both. Overall, the extent of the symptoms of coronary artery disease depends on the location, severity, and how fast the disease will start from the limited blood supply.…
Atherosclerosis is a form of cardiovascular disease in which the inner layers of artery walls are made thick and irregular by plaque deposits; arteries become narrow and blood supply can be reduced. (pg. 409) Atherosclerosis is deposited by fatty substances (called plaques) in the walls of the arteries. (pg.249) The arteries become narrow due to a person having high blood pressure which makes the heart work harder which forces the blood through the arteries making it narrow and stiffen. They also become narrowed buy deposits of fat, cholesterol, and other substances. The lining arteries gets damaged by the endothelial cells (cells that line the arteries) becomes damaged. This is caused by smoking, high blood pressure, high insulin or glucose levels, and deposits of oxidized LDL particles. Next the body responds to these damages by causing information and changes in the artery lining that…
Coronary heart disease is most often caused by a condition called arteriosclerosis, which takes place when a fatty material along with a substance called plaque builds up along the walls of the coronary arteries causing them to become narrow and restrictive. As the coronary arteries grow rigid and narrow, the combination can restrict the blood flow to the heart causing it to stop or slow down resulting in chest pain, stable angina, shortness of breath, along with other symptoms, eventually resulting in a heart attack (Blank & Smithline, 2002). However, most individuals with coronary artery disease do not display symptoms of the disease for decades, even as it progresses. The first onsets of symptoms are often sudden resulting in myocardial infarctions, also known as heart attacks. (American Heart Association, 2011; DeVon, & Zerwic, 2003).…
