M. T's Coronary Artery Analysis

Many of the risk factors for cardiovascular disease cause problems because they lead to atherosclerosis. Atherosclerosis is the narrowing and thickening of arteries and develops for years without causing symptoms. It can happen in any part of the body. Around the heart, it is known as coronary artery disease, in the legs it is known as peripheral arterial disease. The narrowing and thickening of the arteries is due to the deposition of fatty material, cholesterol and other substances in the walls of blood vessels. The deposits are known as plaques. The rupture of a plaque can lead to stroke or a heart attack. (World Heart Federation).

Coronary artery disease (CAD) develops when plaque builds up in the narrow arteries of the heart. The arteries that are affected supply blood to your heart, oxygen, and numerous amounts of nutrients to the heart. The plaque that builds in the arteries is from the amount of cholesterol that is accumulated in the arteries. The plaque that builds within the arteries of the heart decrease the blood flow to the heart often resulting in chest pain (angina), shortness of breath, or other symptoms. This disease is often not diagnosed until the patient has a heart attack. The reason that coronary artery disease goes unnoticed is because this disease develops over decades. “Heart disease is the leading cause of

The most common physiological process leading to a myocardial infarction is the occlusion of coronary arteries by a process known as atherosclerosis. In fact, atherosclerosis is present in more than 90% of persons with coronary heart disease.1

This chronic disease is also known as atherosclerosis and is characterized as a fatty plaque build-up in arteries which blocks the blood flow to the vital organs in ours bodies; with the heart being the main target. This potentially life-threatening blockage results in starvation and deprivation of oxygen enriched blood and vital nutrients that are necessary for the heart to maintain proper function; and that is being able to pump blood efficiently. Typically, it is said that the process of heart disease may begin during childhood years of an individual’s life. In a healthy individual; our arteries start out smooth and elastic, allowing effortless blood flow to our hearts and throughout our bodies. As this cholesterol-laden plaque begin to accumulate within the walls of blood vessels (which may be caused by a poor diet, and lack of physical activity, or simply hereditary) the vessels become inflamed. With the body’s effort in healing itself, this destructing plaque begins to release substances such as lipoprotenins, calcium, and inflammatory cells throughout the bloodstream.

Nevertheless, there is an understandable and noticeable link between circulatory related diseases and lifestyle diseases, such as Coronary Heart Disease. Coronary heart disease can occur when fatty acids, such as cholesterol in an inadequate diet, build up in the walls of the coronary artery. These fatty deposits collect minerals and harden to become a plaque. Eventually, this plaque grows and can swells up, forming an aneurism. In some cases, this aneurism may burst leading to instant death. As it continues to grow and swell up, it finally blocks the artery completely and forms blood clots. This is known as coronary thrombosis. A myocardial infarction, or in other words as heart attack, occurs when no oxygen is able to reach the coronary artery and thus it is unable to fulfil its role in providing the heart muscle with a sufficient supply of blood. Heart attacks are very common in the society nowadays, especially occurring in smokers or obesity related diseases (Millar, June 2014)

Coronary Artery Disease, also known as CAD, is the most common form of heart disease. (Heart and Stroke Foundation, 2009) Coronary Artery Disease obstructs the blood flow in vessels that provides blood to the heart which is caused by the buildup of plaque on the artery walls. (Rogers, 2011, p.87) (Heart and Stroke Foundation, 2009) Plaque is a yellow substance that consists of fat substances, like cholesterol, and narrows or clogs the arteries which prevents blood flow. (Heart and Stroke Foundation, 2009) Plaque can build up in any artery but usually favors large and medium sized arteries. (Heart and Stroke Foundation, 2009)

Coronary artery disease (CAD) is the commonest heart disease in the United States1. Approximately, 29% of patients with Myocardial Infarction ( MI ) present with ST- elevation Myocardial Infarction ( STEMI )2. STEMI is the result of complete occlusion of a major epicardial coronary artery due to thrombus formation. STEMI from a small coronary artery presenting as substantial EKG abnormalities similar to occlusion of a major artery and hemodynamic instability is a rare entity. The epidemiology, typical clinical presentation, outcomes, and optimal management in this group of patients are not sufficiently known.

There are many races, hurdles, and obstacles to contend with throughout the course of life such as: life itself, family and health. In the realm of Certified Nursing, I have become more intent on knowing more about the lifestyles of the people, and the good and bad results of daily tasks that ensure their happiness. Safety, and the many diseases/disorders that have been encountered by others, can only be counter-acted by better knowledge, resources, and means of assurance in providing ways of increasing the (ADLs). While reading, I came across the disorder of Myocardial Infarctions, and found the information to be remarkably interesting. First of all, I learned that infarctions are commonly known for being obstructions of the blood supply to the organs and tissues; whether by the thrombus or embolous. This obstruction causes tissues to die. ” (Medicine Net, 2015).There’s different kinds of infarctions, such as: Myocardial, Acute, Cerebellar, and Right Ventricular. Therefore, myocardial infarctions are “irreversible necrosis of heart muscle, which are secondary to prolonged ischemia” (emedicine, 2015). Therefore, myocardial infarctions are “irreversible necrosis of heart muscle, which are secondary to prolonged ischemia” (emedicine, 2015).

Coronary illness is the development of plaque (fat store on the inward dividers of the veins) in the coronary conduits that supply O2 rich blood to the heart muscle, the development of plaque is called atherosclerosis. After some time passes plaques may solidify therefore limiting blood stream or totally obstructing the corridor. The development of plaque is straightforwardly identified with a people way of life, normal danger elements incorporate stoutness, high blood cholesterol and diabetes. At the point when the endothelium is harmed by blood stream, the cholesterol and fats in the blood get stuck shaping plaques. This outcomes in hypertension due the heart endeavoring to supply obliged levels of blood to the body. In the event that the blood stream to the heart muscles is limited or blocked it may

One of the patient’s secondary diagnoses is atherosclerotic heart disease of native coronary artery without angina pectoris. He had a heart valve replacement in 2011. Atherosclerosis is a disease in which plaque made of fat, cholesterol, calcium, and other substances builds up inside the arteries. This is an issue because the plaque hardens over time and narrows the arteries, which then limits the flow of oxygenated blood to vital tissues. This condition can lead to heart attacks, strokes, and death. Coronary artery atherosclerosis is the single largest killer of both men and women in the United States (Boudi, 2016). The patient’s atherosclerosis is located in the coronary artery. This artery is one of two main blood vessels that branch off

Artery coronariasLa artery disease coronary (EAC) affects more than 15 million Americans, being both the most common type of cardiovascular disease. The EAC and its complications, such as arrhythmia, angina pectoris and heart attack, are the main causes of death in the United States. The most frequent cause of EAC is a disease known as 'atherosclerosis' that occurs when forms a waxy substance within the arteries that irrigate the heart. This substance, called «plate», is composed of cholesterol, fatty, calcium and a coagulant substance called «fibrin». Identified two types of plate: plate hard and soft plate.

As the blood vessel progressively narrows from continuous cholesterol deposition, the myocardium is insufficiently supplied with oxygen making the heart ischemic. Eventually, viable tissue becomes necrotic increasing the likelihood of a myocardial infarction (MI). An MI can also occur if the fibrous cap is ruptured and a thrombus or embolus is released, completely blocking blood supply to the heart. This may be caused by a sudden increase in blood pressure, vasospasm, or tobacco chemical assault. 4(111)

Old Myocardial Infarction(MI) (ICD I25.2)- (Patho Statement) Plaque formation can build up in the interior walls of the heart muscles. Plaque is often made up of WBC, cholesterol and fat. This plaque build up reduces the blood flow and oxygen to the heart causing injury (Lu, Liu, Sun, Zheng, & Zhang, 2015). These heart attacks can be acute or silent. They often present with symptoms of chest pain, left arm pain that can radiate to the neck, shortness of breath, sweating, nausea, vomiting, abnormal heart beat,

Atherosclerosis, the underlying cause of coronary heart disease which can affect any artery in the body, is essentially the narrowing of arteries due to excessive build up of cholesterol-rich lipids known as plaque (Insull 2009). Once the arteries become narrow, the flow of blood will be constricted, and the amount of blood, nutrients and oxygen that are able to reach the heart are reduced. As a consequence, the heart becomes increasingly hypoxic resulting in ineffective contraction. The aftermath of narrow arteries often poses serious consequences as it has a high probability of causing heart attack, angina, or even stroke (Marieb & Hoehn 2010; Insull 2009). Despite the fact that arteries will harden naturally as people age, the rate of plaque development is determined by the number of risk factors (Insull 2009). This essay will discuss and review the procedure in which the risk factors: hypertension, abnormal level of blood lipids, and smoking took to assist in the development of atherosclerosis.

Mr. R is a 69-year-old male admitted to the cardiac intensive care unit with angina pectoris. He has a history of coronary artery disease, hyperlipidemia, and hypertension. The patient is planned to have a coronary artery bypass graft (CABG) this afternoon to repair his ventricular function. My preceptor and I spent the morning preparing Mr. R for his approaching surgery.
