Heart disease affects many people around the world. Coronary heart disease can be deadly, although, with correct diet and exercise it can be prevented. According to (Payne, Hahn, & Lucas, 2013) three hundred thousand deaths each year are from "sudden cardiac deaths". Coronary heart disease happens when there is damage to the vessels that supply blood to the heart muscle (Payne, Hahn, & Lucas, 2013). Imagine having a stuffy nose and not having the capability to breath in as much oxygen as normal. This is what it is like for the heart muscle when coronary heart disease sets in.
Sometimes people have symptoms of coronary heart disease. Although this is not always the case. According to the United States Department of Human Health and Services
It was to this respect that, the search could detect ‘’hypertension’’ as the leading risk factor for heart disease. And this preceded three quarters of heart failures cases as compared to coronary artery disease, which led to most heart failures in less than 40% of the cases. Also, an increase in left ventricular end-diastolic diameter became a mirror to the Framingham study as incident heart diseases in the individuals who are free from myocardial infarction. Although studies have shown that, the manifestation of heart failures can be present without the left ventricular systolic dysfunction, other risk factors could lead to that. Also, they (Framingham study) were able to detect ‘’too much of cholesterol’’ as a link to cardiovascular diseases. Moreover, research believed that has elevated among certain heart diseases such as coronary heart often leads to stroke, too high blood pressure among numerous patients. Having said that, the search discovered ‘’obesity’’ also as a concomitantly with hypertension which elevates lipids and diabetes versus questions on smoking behavior. Having said that, these risk factors are believed to have attributed to heart diseases. Therefore, it became a national concern to the general US population and that of the fourth director of Framingham heart study, William Castelli
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.
A heart attack (myocardial infarction) is the death of heart muscle due to the loss of blood supply. Usually, the loss of blood supply is caused by a complete blockage of a coronary artery by a blood clot. A coronary artery is an artery that supplies blood to the heart muscle. Death of the heart muscle causes chest pain and electrical instability of the heart muscle tissue. Electrical instability of the heart causes ventricular fibrillation (chaotic electrical disturbance). Orderly transmission of electrical signals in the heart is important for the regular beating (pumping) of the heart. A heart undergoing ventricular fibrillation quivers, and can not pump or deliver oxygenated blood to the brain. Permanent brain damage and death can occur unless oxygenated blood flow is restored within five minutes.
Signs and symptoms of heart failure include shortness of breath, edema, rapid or irregular heartbeat, weakness, and elevated blood pressure. These signs and symptoms appear slowly in the disease, such as when a person is active, but overtime they will become present when that person is at rest (Couzens, 2014). People at risk for heart failure include those who have sleep apnea, have had a heart attack, have high blood pressure, have diabetes, are overweight, and those abuse alcohol use. There are many other risk factors also; these are just to name few.
Heart disease describes a range of conditions that affect your heart. Diseases under the heart disease umbrella include blood vessel diseases, heart rhythm problems, and heart defects. The major cause of this is a build-up of fatty plaques in the arteries. Plaque build-up thickens and stiffens the vessel walls, which can inhibit blood flow through the arteries to organs and tissues.
Today, cardiovascular disease is “the number one killer in the United States and the developed world” (Sapolsky, 2004, p. 41). Coronary heart disease (CHD) is the most common form of cardiovascular disease, and is responsible for claiming an unreasonable amount of lives every year. CHD can begin to accumulate in young adults, but is prominently found in both men and women in their later adult lives. As a result of CHD, men typically experience heart attacks, whereas women present with chest pains, known as angina (Matthews, 2005).
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.
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.
Coronary heart disease occurs when some of the arteries that carry blood to the heart muscle become narrowed with fatty deposits. In this condition fatty deposits called plaque, composed of cholesterol (see later) and fats, build up on the inner wall of the coronary arteries. When arteries are narrowed, the heart is not fully supplied with the oxygen and other nutrients it needs. If an artery is completely blocked, a heart attack occurs. Heart disease is very common.
...ital if you have symptoms such as dizziness, fatigue, chest pain, or heartburn it is essential that you get to a hospital immediately, just to make sure that you can get the treatment that you need so you and your family do not have to experience a myocardial infraction. Even though coronary artery disease usually affects persons over age 60, the disease can still be seen in people who are much younger for various reasons. The diagnosis of coronary artery disease remains the number one cause of hospitalization and death in the adult population in the United States today, but with the proper treatments, knowing the risk factors of coronary artery disease and medical technology such as stents, coronary endocartomy, and coronary bypass grafting that we have available to us today the prognosis can be positive for many patients and will save more lives than not knowing.

Often times there are no symptoms of the underlying disease of the blood vessels. More times than not, a heart attack or stroke is the first warning or sign of the underlying disease. Since signs and symptoms of cardiovascular disease are not always apparent, it is important to know the symptoms of a heart attack so medical attention can be sought out immediately. According to...
There are many other signs of a heart attack, like dizziness, faintness, shortness of breath, or nausea.... ... middle of paper ... ... Prognosis Survival of a myocardial infarction is at a higher risk of having another MI again than those that have never had one before. They have the risk of heart failure; they may suffer from angina pectoris (a heart disease with similar symptoms of a heart attack), and many other diseases like diabetes, hypertension, etc.
The ischemic heart disease (IHD), also known as coronary heart disease (CHD), occurs when the supply of the blood to the heart is interrupted due to the blockage of the coronary artery (Cooley, 2014). CHD is the most common type of heart disease and the leading cause of death in the United States (CDC, 2015) but what happens exactly in the IHD’s disease process? Anwar Jasib Thaaban (2015) stated that the inflammation and the oxidative stress might contribute to the pathology of the IHD. Oxidative stress occurs when there is an overproduction of the reactive oxygen species (ROS), which impairs the anti-oxidant defense system (Anwar Jasib Thaaban, 2015). It is fascinating to know how the IHD and polyphenols are interrelated. Polyphenols that
Heart Disease is a very dangerous and life threatening disease caused by the hardening of the arteries, this causes them to become narrow, making blood flow slower. This disease can be scary and unexpected but there are ways to know you have it and ways to prevent it. There are many symptoms that come along with Heart Disease, but there are few that are most popular. Dizziness, sweating, feeling ill or nausea, and chest pain are just some of the many different symptoms.
