Coronary artery disease (CAD) is one of the most common types of heart diseases. In the United States, CAD is the leading cause of death in both men and women. The disease occurs when a waxy substance called plaque builds up inside the coronary artery. The coronary arteries supply oxygen-rich blood to your heart muscles. Both of my grandfathers suffer from coronary artery disease and I want to learn more about the disease to better understand how it affects them both mentally and physically.
Although coronary artery disease does not have a specific who, what, or when it is said to have been discovered in the 13th century. Leonardo Di Vinci was alleged to have looked into coronary arteries. William Harvey in the 16th century was also credited to have discovered how the blood moves throughout the body. It was not until the 19th century when doctors and researchers started to redirect their attention to coronary arteries. Near the end of this century researchers realized the blockage of arteries in a dog caused theirs ventricle to "quiver" and kill them in a short amount of time. In 1878, Ludwig Hektoen theorized that some diseases were a result of coronary artery disease such as myocardial infraction. Until the mid-1900s researchers were not positive on what coronary artery disease actually was. Over the past 60 years a vast amount of data has been discovered. Recently, an Egyptian princess that lived more than 3,500 years ago that died from coronary artery disease was discovered by scientists in 2011.

...oblems and keeping up a healthy lifestyle. With heart disease being the number one killer in both men and women there are many support groups and organizations funding researches to find cures. Some patients have to give up working or physical activities due to the heart not being able to handle it. CHD sufferers generally have to give up alcohol which can cut back on people's social life. These outcomes of having CHD usually take a toll of people both mentally and physically, but with the help of family and friends most sufferers fight through it.

Coronary artery disease is a heart disease characterized by narrow arteries and restricted blood flow in arteries and is the major cause of morbidity and mortality globally.[1] According to WHO estimation, 6.8% in men and 5.3% in women are affected globally.[2-4] Cardiovascular disease account for 29% of all deaths in Canada; of all the cardiovascular death, 54% and 23% was due to ischemic heart disease and heart attack, respectively. The total costs for heart disease and stroke were more than $20.9 billion every year. [5,6] With more than 1 artery impacted, multivessel coronary artery disease is more complex and more likely accompanied by other comorbidities including diabetes or high blood pressure; multivessel coronary artery disease usually is more difficult to deal with, has worse prognosis and cost more compared with single coronary artery disease.

In 1615 at the age of 37 Harvey became the Lumleian Lecture specializing in Surgery. William Harvey discovered his finding of the Circulation of Blood by ignoring medical textbooks and dissecting animals. He gained all or most of his learnings from observations of cutting open veins and arteries of living animals. Many people of this modern time thought because there weren’t any anesthetics that Harvey was cruel for cutting open living animals. I think that if it wasn’t for William Harvey and all of his studies and dissections that we wouldn’t be able to learn teach and save as many people as we can today. We as people have learned a lot from the many studies and dissections throughout Harvey’s lifetime. We have learned that blood, arteries, and veins are all within the same origin, blood in the arteries sent to the tissues are not stay there, the body‘s circulation mechanism was designed for the movement of liquid and that blood carrying air is still blood, the heart moves all movements of blood not the liver, hearts contract the same time as the pulse is felt, ventricle’s squeeze blood into main arteries, the pulse is formed by blood being pushed into arteries making them bigger, there are no vessels in the heart’s septum, lastly there is no to in from of blood in the veins there is only
Heart disease is one of the most common causes of the mortality and morbidity in most well developed countries. They come in different forms such as stroke and other cardiovascular diseases and it’s the number one cause of death in the state of America. In the year 2011 alone nearly 787,000 people were killed as a result of this epidemic. And this included Hispanic, Africans, whites and Americans. As for the Asian Americans or pacific Islanders, American Indians and the natives of Alaska, the concept to them was a second only to cancer. However, statistics has proved that a person gets heart attack every 34 seconds and in every 60 seconds, someone dies out of it which include other related event. Additionally, majority of the women are the

There is also counseling, with peer support, and support groups this can be very helpful. There are 3 support groups I found, National Adrenal Diseases Foundation, The MAGIC foundation, and the CARES foundation. All of them are focused to improve the lives of individuals with this disease.
Atherosclerosis begins when the inner wall of the artery becomes damaged and cholesterol and fatty plaques begin to lodge in the arteries. Damage to the endothelial wall inside the artery can be caused by hypertension, hyperlipidemia, and hyperglycemia (“Subclinical Atherosclerosis..” 443). When this happens, the immune system responds by sending monocytes to the damaged area. The monocytes turn into macrophages; their job is to eat up the excess cholesterol and unblock the artery. The macrophages are unable to digest all of the cholesterol, and as a result turn in to foam cells. When many macrophages are turned into foam cells, plaque results, and protrudes into the arterial wall, restricting blood flow and raising blood pressure (“Atherosclerosis Growth Process.” 8). If the plaque becomes too large it may break, releasing plaque into the blood. This can cause a great reduction in blood flow or a clot, resulting in stroke or myocardial infarction (“Stroke Risk.” 3).
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.
Cardiovascular Disease is defined by the American Heart Association as “Heart and blood vessel disease”. Atherosclerosis of the arteries, can lead to hypertension, heart failure, arrhythmias, heart valve problems, myocardial infarctions or a stroke (AHA, 2016). In this paper, all of heart and vessel diseases aforementioned, will be considered cardiovascular disease (CVD). According to
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).
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.
The Heart is a very important organ in the body. It is what keeps your blood flowing and your organs going. It is a tireless muscle that pumps more than two thousand gallons of blood every day. The blood that is pumped is filled with nutrition and oxygen (Colombo 7). It travels through out your body in less than sixty seconds. So it needs to be taken extra good care of. When abuse is put on the body, the heart’s performance is not at its best. The Heart is a major organ that needs loving and care. Everyone has only one and by abusing it, they are cutting their live span little by little. People can live their lives freely but how they choose to live them could be the difference between life and death.
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.
