Coronary Artery disease is when plaque builds up in the arteries around the heart, which can cause a heart attack. Coronary Artery disease is also one of the leading causes of death of in the United States. Many different medical places are trying to come up with a resolution to this disease, however there are only temporary fixes. The United States is spending a major amount of money to try and find a solution. There are many different symptoms include chest pressure or pain, shortness of breath, pain or discomfort in the arms or shoulder, pain or discomfort in the jaw, neck or back, and feeling weak, light headed, or nauseous. There are several ways to prevent Coronary Artery disease such as not smoking, or to have more exercise in a person lifestyle. Anything healthy a person can do will help prevent Coronary Artery disease, not only will the person feel better but their body will thank them later. Coronary Artery disease is a very serious disease that should be taken very seriously, millions of Americans are affected every year.

Coronary artery disease is the build-up of plaque in the arteries supplying blood to the heart. The decrease in blood flow due to plaque buildup can lead to chest pain, also called angina, or progress to a heart attack. The five most common symptoms of a heart attack are chest pressure or pain, shortness of breath, pain or discomfort in the arms or shoulder, pain or discomfort in the jaw, neck or back, and feeling weak, light headed, or nauseous. “Heart disease facts.

...r–that’s 1 in every 4 deaths. Heart disease is the leading cause of death for both men and women. More than half of the deaths due to heart disease in 2009 were in men. Coronary heart disease is the most common type of heart disease, killing more than 385,000 people annually. Every year about 715,000 Americans have a heart attack. Of these, 525,000 are a first heart attack and 190,000 happen in people who have already had a heart attack. Coronary heart disease alone costs the United States $108.9 billion each year. This total includes the cost of health care services, medications, and lost productivity. “Coronary artery disease. (2013) Texas Heart Institute” Cardiovascular disease is the leading cause of death for both men and women in the US, affecting more than 13 million Americans. Coronary heart disease is a major health issue that should be treated right away.
An artery is an elastic blood vessel that transports blood away from the heart. There are two main types of arteries: pulmonary arteries and systemic arteries.
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].
Cardiovascular disease is currently the leading cause of death in the United States. It is responsible for one in four deaths every year, about 600,000 mortalities. This disease affects men and women, as well as every ethnic group. Coronary artery disease is the most common cardiovascular disease, representing approximately 400,000 deaths per year of the aforementioned 600,000 total deaths from cardiovascular diseases as a whole. In 2010 alone, coronary artery disease cost the United States $108.9 billion for health care services, medication, and lost productivity. These chilling statistics, published every year by the American Medical Association, demonstrate the immediate need for new and innovative ways to prevent, detect, and treat coronary heart disease. This paper will explore the molecular biology behind the disease while explaining the current treatments and prevention that are available today, why they work and what can be done to improve them.
Blood clots can accumulate due to atherosclerosis plaque buildup. When plaque builds up and break off in the artery a blood clot can form. If the blood clot is large enough, it can particularly or completely block the artery. A blocked artery segment is what causes tissue death due to deprived oxygenated blood. If this problem is not treated right away, the portion of the heart fed by the artery will begin to die. Scar tissue will form on what was once health heart tissue. The heart damage may not be noticeable, or it may cause severe or long-lasting problems. (National Heart, Lung, and Blood Institute) Another cause of heart attacks is due to a severe coronary artery spasm, this is this least common cause. Coronary artery spasms are brief temporary tightening or contraction of the muscles in the artery wall. Spasms can emerge in coronary arteries that aren 't affected by atherosclerosis. It 's not clear as to why these spasms arise but they are most likely due to: physical exertion, emotional stress or pain, exposure to extreme cold, cigarette smoking, cocaine
Arterioslerotic heart disease, also referred to as ischemic heart disease or coronary heart disease (CHD), is a general term used for a group of disorders where there is thickening and elasticity loss, as well as hardening of artery walls. The most common form of arteriosclerosis (other term for arteriosclerotic cardiovascular
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.
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.
Cardiovascular Disease is broad term that encompasses several diseases related to heart or blood vessels or both. Some of which include, congenital heart abnormalities, ischemic heart disease, hypertension, diseases of the cardiac valves, cardiomyopathies, and cancer. There are many causes of CVD but hypertension and atherosclerosis (hardening of the artery) are most common. It’s true when H.L. Menchen said, “As the arteries grow hard, the heart grows soft.”
Although atherosclerosis affects millions of people around the world, there are many ways to prevent and treat it once it has developed. Simple life style changes can greatly reduce the inflammation and damage to the endothelial wall of the artery. It is very important that people who have high blood pressure or diabetes get regular checkups; if atherosclerosis goes untreated, the adverse effects, such as stroke or myocardial infarction can be deadly.
Because your heart needs oxygen the most when it is working the hardest, angina is most likely to occur during exercise. And if the heart muscle is deprived of oxygen for long enough, it will die, resulting in a heart attack, or myocardial (heart muscle) infarction (tissue death) (Weisse p. 54). As you can see, preventing this disease should be a number one priority.The prevention of heart disease should begin in childhood and continue throughout life. But it is never too late to start; people of all ages can benefit greatly from diet, exercise, smoking cessation, and stress control to prevent heart disease. We should try to control our risk factors, such as cholesterol, high blood-pressure, stress control, smoking habits, lack of exercise, and dietary problems, or more specifically, obesity.
Ischemic Heart Disease, also known as Coronary Artery Disease, is a condition that affects the supply of blood to the heart. Coronary artery disease may show no signs of symptoms, or chest pain before you know heart attack. The blood vessels are narrowed or blocked due to the deposition of cholesterol on their walls. This reduces the supply of oxygen and nutrients to the heart muscles, which is essential for proper functioning of the heart. This may eventually result in a portion of the heart being suddenly deprived of its blood supply leading to the death of that area of heart tissue, resulting in a heart attack. The cardiovascular issue has been a big problem for people who
The symptoms of coronary artery disease can take a while to become apparent. Which is why it attacks older people rather than younger. The symptoms start to appear as more of the blood flow is restricted. One symptom is called angina. This is when there is pain in the middle or left side of the chest. The common trigger is an emotional response. The pain typically stops after the person has calmed down or stopped intense physical activity. The pain has been known to gravitate towards the neck and arms. The patient affected could also have a shortness of breath. This is a result of the heart not pumping enough oxygen to the body. The biggest symptom is a heart attack. This is when
With medication and lifestyle changes, plaques may slow or stop growing. They may even shrink slightly with aggressive treatment. Reducing the lifestyle risk factors that lead to atherosclerosis will slow or stop the process. That means a healthy diet, exercise, and no smoking. These lifestyle changes won't remove blockages, but they’re proven to lower the risk of heart attacks and strokes. Taking drugs for high cholesterol and high blood pressure will slow and perhaps even halt the progression of atherosclerosis, as well as lower your risk of heart attacks and stroke (3). Atherosclerosis starts early. In autopsies of young American soldiers killed in action in the Korean and Vietnam wars, half to three-quarters had early forms of atherosclerosis. Even today, a large number of asymptomatic young people have evidence of atherosclerosis. A 2001 study of 262 apparently healthy people's hearts may might surprise you. 52% had some atherosclerosis. Atherosclerosis was present in 85% of those older than 50.17% of teenagers had atherosclerosis. No one had symptoms, and very few had severe narrowing’s in any arteries. This was very early disease, detectable only by special tests. If you are 40 and generally healthy, you have about a 50% chance of developing serious atherosclerosis in your lifetime. The risk goes up as you get older. The majority of adults
Atherosclerosis refers to the accumulation of fatty plaques or atheroma’s in the walls of the arteries. These plaques are made up of platelets, clots, and cholesterol. Over time, thickened walls reduce blood flow through the coronary artery or completely blind the artery in case a blood clot forms. This leads to a heart attack.
The causes cardiovascular disease is when a person has a buildup of plaque on the walls of his or her heart. The reason that these accumulations occur, when a person has an unhealthy lifestyle when eating causing stiffness of the heart. The fat around the heart will have the person
