The Disease Process of Atherosclerosis & its Complication; Myocardial infarction Loretta Zambito McMaster University HTH SCI 2C06 Dr. Ruth Hannon March 11‚ 2013 Atherosclerosis is the primary topic for this research paper. It is a disease process that can lead to many complications‚ one of which is called myocardial infarction; otherwise known as a heart attack. Atherosclerosis‚ or the hardening of the arteries‚ is defined as a disease characterized by abnormal thickening of the

terms ‘First’ and ‘Second’ windows of myocardial protection to refer to the ‘Classic’ and the ‘Delayed’‚ respectively. Unlike the early phase of preconditioning‚ which lasts 2 to 3 hours and protects against infarction but not against stunning‚ the late phase of preconditioning lasts 3 to 4 days and protects against both infarction and stunning‚ suggesting that it might have greater clinical relevance. There also is a great difference regarding the mechanisms of each type and the cellular changes

Stress is known to have an effect on the psychological factors of the body which alerts the homeostatic state by controlling the functions of the nervous and endocrine systems. Stress activates a development in the cardiovascular system such as acute myocardial infarction (rosengren et.al 2004). Each individual responds differently to stress as it depends on the psychological factors. Selyes model of stress is psychological factor which is an individual reaction to stress. The general adoption

Most likely diagnosis considering the clinical picture Localised chest pain over the sternum is a common symptom and can be an indicator of a large assembly of conditions. Commonly seen in cardiac diseases including angina pectoris‚ myocardial infarction and pericarditis (Patient.info‚ 2017).

flow to the heart is reduced as plaque narrows the coronary arteries‚ thereby decreasing the oxygen supply to the heart muscle. This loss of oxygen in the blood can lead to ischemia and later‚ myocardial infarction. The patient in this case is a 63 year old male with CAD that led to a myocardial infarction in April of 2003. In speaking with the patient about his condition‚ a series of questions regarding the meaning of the illness to him‚ his family‚ and how he dealt with it were asked. The patient

Acute Coronary Syndrome (ACS) is a medical condition that encompasses various heart-related ailments such as acute myocardial ischemia‚ unstable angina‚ non-ST-segment elevation myocardial infarction (NSTEMI)‚ and ST-segment elevation myocardial infarction (STEMI) (Kumar & Cannon 2009). NSTEMI and STEMI begins with atherosclerosis which happens when a plaque known as atherosclerotic plaque is formed from years of cholesterol deposits within the artery wall. When this ruptures the platelets clump

Executive Summary Fibrinolytic therapy has been a significant means of establishing reperfusion in patients whom have had a myocardial infarction or some sort of blood clot. However‚ limitations to the use of thrombolytic therapy that must be taken in to account are intracranial bleeding‚ inability to start thrombosis in Myocardial Infarction flow in patients‚ and high percentage of recurrent ischemia and reocclusion.
