Coronary Heart Disease
Coronary heart disease occurs when the coronary arteries become
partially blocked from, cholesterol and fat, circulating in the blood.
This causes a build up inside the walls of the arteries. This only
occurs if the levels of fat and cholesterol are extremely high in the
blood that there is a greater chance that it will be deposited onto
the artery walls. If the arteries become completely blocked, the
patient will have a myocardial infarction, commonly known as a heart
attack. A heart attack can cause permanent damage to the heart muscle,
and can sometimes be fatal if immediate treatment is not given. There
are other contributing factors other than fatty deposits which can
cause coronary heart disease such as high blood pressure. The focus of
this quote is that this disease is caused by the person who has
contracted it. However, this statement is not totally correct because
there is evidence to suggest that heart disease can occur from
uncontrollable circumstances; such as gender, heredity and age. In
this essay I shall evaluate both controllable and uncontrollable
circumstances for someone to suffer from coronary heart disease.
Obesity is one risk in which it is often brought about by the person
themselves. This is because it is in the control of the person.
Therefore their decisions can be made without consultation. However,
by being over weight it increases the total cholesterol levels in the
blood (2). Liver makes cholesterol from the saturated fats in the
blood; it enters the blood and is transported around by proteins known
as “lipoproteins”. There are two types of lipoproteins low density and
high d...

contribute to causing heart disease and the same symptoms.

LDL or bad cholesterol comes from food that is a high source of cholesterol and/or saturated fats. Plaque forms when bad or LDL cholesterol builds up in your bloodstream and attaches to the arterial wall, as more LDL builds up the plaque becomes larger, this can become a major problem for your cardiovascular system. Because plaque is a substance that has rough edges, it reduces the elastic nature of the artery which means your heart will have to work double-time to pump the necessary blood to all your limbs, that will mean your limbs won’t get the amount of oxygen that they require to function properly. Plaque can also narrow the area blood has to pass through, this means your heart has to work overtime and overall capacity of your cardiovascular system is lowered. When the LDL cholesterol embeds itself in the wall of the artery it than damages the artery then blood pressure expands it which causes an aneurysm. When an aneurysm is too weak there is a high possibility of it bursting, when that happens it leaves the cells in and around that area without oxygen. If that artery is connected to a major vital organ the person will most likely die. When the blood flow is slowed it shows a greater risk for blood clots and although blood clots are natural and important to healing broken blood vessels, if blood clots gather inside the blood vessel this proves to be a serious health risk. The clots have the possibility to get stuck and completely cut off the blood flow to cells, leaving them without oxygen and causing them to die. If a clot gets inside a blood vessel connected to a major organ this could cause the person to die. The heart is fed by the coronary artery, if plaque or a blood clot blocks off blood flow to the heart, the heart ...
Being overweight or obese are risk factors for many chronic health conditions such as heart disease, diabetes, and … cancers.”
Coronary artery disease (CAD) is the most common type of multifactorial chronic heart disease. It is a consequence of plaque buildup in coronary arteries. The arterial blood vessels, which begin out smooth and elastic become narrow and rigid, curtailing blood flow resulting in deprived of oxygen and nutrients to the heart [1].
Coronary heart disease is defined by the hardening of the epicardial coronary arteries. The buildup of plaque in the arteries slowly narrows the coronary artery lumen. In order to better understand the physiology of the disease, it is important to first know the basic anatomy of the human heart. The aorta, located in the superior region of the heart, branches off into two main coronary blood vessels, otherwise known as arteries. The arteries are located on the left and right side of the heart and span its surface. They subsequently branch off into smaller arteries which supply oxygen-rich blood to the entire heart (Texas Heart Institute, 2013). Therefore, the narrowing of these arteries due to plaque buildup significantly impairs blood flow throughout the heart.
There are several factors that cause heart disease such as: smoking, certain fats, high cholesterol, high blood pressure, hi...

Atherosclerosis is defined as the formation of fatty plaques in the walls of arteries, restricting blood flow to deep tissues (Martini).
One of the leading causes of death in the United States is heart disease. “Approximately every 29 seconds one American will have a heart attack, and once a minute one American will die from a heart attack” (Ford-Martin and Odle, 915). According to the Gale Encyclopedia of Alternative Medicine men over the age of 45 and women over the age of 55 are considered at risk for heart disease. Heart disease is a major cause of death. It is beneficial to individuals who seek to prevent heart disease to recognize the risks leading to heart attacks as they are one of the primary indications of developing heart disease; especially those that fall into the at risk age groups. These risks consist of some that cannot be changed such as heredity risks, or those that can change such as smoking habits. It is very important to know these specific risks for prevention and to understand the symptoms of heart attacks, such as sweating or the feeling of weakness so if these or other symptoms occur people are aware. Finally heart disease treatment is of vital importance if you experience a heart attack so you can learn how to prevent another one from occurring.
A disease or a disorder for the blood vessels can be fatal. The coronary arteries supply and maintain the myocardium. Coronary artery disease can cause a heart attack or hypertension when blood vessels get small or filled up with cholesterol, scar tissue, or calcium. Other problems can happen also. For instance disorders for the heart valves or for the heart muscle and pericardium.
Heart disease is the leading cause of death for both women and men in the United States. It is very important to learn about the heart to prevent heart disease. Many forms of heart disease can be prevented and treat with healthy lifestyle choices. For someone who has heart disease or does not; there is information, facts, symptoms, different types, diagnoses, tests, treatment, care, and living and managing that can be given.
Coronary heart disease or coronary artery disease affects 16.8 million people in the United States and causes more than 607,000 deaths annually (Lemone, chap.30). It is caused by atherosclerosis which is the accumulation of fatty deposits in the arteries causing impaired blood flow to the myocardium. CAD or coronary artery syndrome is usually without symptoms but may induce heart attack, angina and acute coronary syndrome if not properly treated. There are many risk factors associated with CAD like obesity, high cholesterol diet, hereditary, physical inactivity, just to name a few. Patients with CAD may be unable to identify and manage their risks factors. It is imperative for nurses to educate the patient about CAD and measures to enhance their health.

What is coronary heart disease (CHD)? It is a disease when plaque gets built up in the coronary arteries; and the job of the arteries are to provide rich-oxygenated blood to the heart muscle. Built plaque in the arteries leads to atherosclerosis and the plaque that is built can result from over the years. Throughout the years, the plaque tends to get hard or can rupture. If hardened, the arteries are now narrow and have weakened the flow of blood that travels to the heart. Blood clots can form from the plaque rupturing which can cause a great chance for the blood flow to be mostly blocked or blocked altogether. There are other names for coronary heart disease such as coronary artery disease, atherosclerosis, ischemic heart disease, etc.
Etiology Myocardial infarction occurs when the coronary arteries are blocked by a blood clot. It is commonly known as a “heart attack”. The heart needs its own constant supply of oxygen and nutrients to work properly. Two coronary arteries deliver oxygenated blood to the heart, and if one of these two arteries fails or becomes blocked, then a portion of the heart will not acquire the necessary oxygen. This clot could be because of CAD (coronary artery disease), which happens when the inner walls of the coronary arteries thicken because of buildup of cholesterol, fatty deposits, calcium among other elements that are carried in the blood (Boston Scientific, 2009).
