Myocardium is the special muscle that makes up the heart, and like other body muscles, this particular muscle requires constant oxygen supply. According to Roberts (2015) the arteries charged with supplying heart muscle with oxygen rich blood are referred to as coronary arteries. As a result of blockage of these arteries, oxygen rich blood cannot reach parts of the heart muscle, effectively starving the affected muscle of oxygen. It is the resulting damage or death of the affected muscle that triggers what is referred to as a myocardial infarction or heart attack. The extent of damage depends on whether the blockage affects a smaller branch artery or the main coronary artery (Roberts, 2015) – with the former affecting a smaller area of heart muscle. This particular blockage, according to WebMD (2017), could amongst other things result in heart failure, heart rhythms that are either abnormal or irregular, damage to critical organs like the liver or kidney as a consequence of cardiogenic shock, sudden halting of the heartbeat (cardiac death), etc. In essence, after blood poor in oxygen concentration leaves the right atrium, it travels to the lungs where it is oxygenated and, as WebMD (2017) points out, returned “to the heart via...
In the words of WebMD, “as the atrium contracts, blood flows from your left atrium into the left ventricle through the open mitral valve.”
Myocardial Infarction According to the Centers for Disease Control and Prevention (CDC, 2006), each year approximately 1.2 million Americans suffer from myocardial infarction (heart attack) each year. 40% of these people who a have heart attack will die from it. This equates to a person having a heart attack every 34 seconds, and a person dying from a heart attack every minute. Heart disease is the leading cause of death in
Health Care Services for Myocardial Infarction: Myocardial Infarction (MI) is commonly known as Acute Myocardial Infarction (AMI) is a heart attack disease in which blood supply to a part of the heart is interrupted resulting in ultimate irreversible damage and cell death in that part of the heart (Khan, 2010). As one of cardiovascular diseases, myocardial infarction can be regarded as one of the leading causes of death for men
MI Case Study: Myocardial Infarction At 10:05 A.M., the blockage that had been silently growing in Paul Parker's left coronary artery made its sinister presence known. The 54-year-old accounting executive had arrived with his family at the Denver zoo feeling fine, but suddenly a dull ache started in the center of his chest and he became nauseated. At first he brushed it off as the aftereffects of a company dinner the night
Acute Myocardial Infarction PATHOPHYSIOLOGICAL PROCESS TEMPLATE DISEASE: Acute Myocardial Infarction is a common disease with very grave consequences in morbidity, mortality and cost to the society (Boersma et.al, 2003) It has become the leading cause of death in the developed world. It has been estimated that about 450,000 people die from coronary disease per year in the United States. Myocardial infarction primarily occurs when the blood supply to the heart is compromised. Just like
Heart attack or myocardial infarction occurs when there is an interruption of regular flow of blood to the heart. The blockage, which leads to the interruption of blood flow, has to be long enough that part of heart muscle dies or becomes damaged. This blockage makes the regular and required oxygen supply in the heart. This lack of oxygen supply leads to the death of numerous cells and the chance
5% while 70.5% took Aspirin within six hours after reaching hospital and 76.5% of patients admitted in the NICVD were receiving Aspirin therapy." (Jaiwa, 2006, p.1) Jaiwa reports a more recent study that states findings that out of 52 patients with chest pain only 13 patients or 25% of the 52 received aspirin. The stated reason for not giving aspirin to the other 39 patients included that "chest pain was not
