Clinical Observation and Literature Review: Oxygen Therapy for Acute Myocardial Infarction Introduction Oxygen therapy has been used to manage myocardial infarction for many years now. Oxygen therapy has been used as a strong and effective option because it seems to have the ability to deliver oxygen to the myocardium, helping to decrease the size of the infarct and also improving the clinical health outcomes…
Oxygen therapy is relevant to contemporary nursing practice because myocardium infarcts have now become common occurrences for humans. With increasing rates of obesity, heart diseases have become common health issues. Specifically, myocardium infarcts are some of these issues which have emerged in recent years. It is therefore important for nurses to immediately initiate oxygen therapy for patients having myocardium infarction. For transitional registered nurses, it is also important for them to know how and when to initiate oxygen therapies for their patients. Although these transitional nurses would not have much experience in oxygen therapy, these nurses have to make the necessary adaptations in their knowledge and skills in order to efficiently carry out these therapies. Critical Review In the paper by Nicholson (2004), the author carried out a systematic review seeking to establish the efficacy of oxygen in decreasing acute myocardial ischaemia. The author acknowledged how patients experiencing acute chest pains can effectively be relieved through oxygen therapy, as this type of therapy is known to establish balance in defects seen in ischaemia. Her study was carried out as a systematic review, as such is a secondary research compiling data from other peer-reviewed studies. Studies included in this review were mostly primary studies, including randomized controlled trials and non-randomized controlled trials on acute coronary syndrome. The study was able to establish through its coverage of nine trials, that the efficacy of the oxygen in decreasing myocardial ischaemia was not clear. Based on data, oxygen was also known to reduce the ischaemia, however, some studies also indicated that it also increased ischaemia. In effect, no definite or clear results were apparent from the review. This study is effective in terms of providing systematic sources of information which can be utilized to support the current issue. The methods applied by the author were appropriate and were fully supported by randomized controlled trials. Nevertheless, this study is not considered primary research as the author utilized clinical research by other authors in order to establish a pattern in the clinical practice. There is a need therefore to seek more evidence on the impact of oxygen therapy on myocardial infarction. Moradkan and Sinoway (2010) also carried out their study in order to review data assessing the impact of supplemental oxygen in normoxic patients presenting with coronary artery disease. The authors were also seeking to establish the point that oxygen therapy may have negative effects which must be evaluated before it is utilised. This is another review of data and therefore a secondary research. Nevertheless, it provides critical information on oxygen therapy. In fact, their review was able to establish that supplemental oxygen is being used excessively among cardiac patients, often unintentionally subjecting them to hyperoxia. This study was also able to establish that many medical professionals do not realize that oxygen is vasoactive and when oxygen saturation reaches 100%, increase in blood and oxygen tension may become apparent. The results of this study are however not based on randomised controlled trials and as a result may not have as much credibility as other reviews. Its ...

A 29-year-old female patient was admitted to the internal medicine department with epigastric pain, continuous colic, nausea, and vomiting. The ECG demonstrated an old anterior wall myocardial infarction. The serum creatine phosphokinase (CK) and cardiac troponin T (TnT) levels were normal.
Myocardial infarction (MI) is also called heart attack, which occurs due to, the formation of occlusive thrombus after the rapture of an atheromatous plaque in a coronary artery (Davidson, 2008). Pathophysiology is the study of physiological, mechanical and biochemical functions of the body, the abnormal functioning of the body results from a disease or an abnormal syndrome or the disturbances of body functioning caused by a disease (Luis, 2012).
Advanced Cardiac Studies 1- Why are MCL1 and MCL6 useful for cardiac monitoring in the prehospital setting when 12 lead ECG is not available? How are they obtained and what pertinent information can be gathered from them? In the prehospital setting, paramedics are usually not equipped with the proper medical tools which would ensure the efficient delivery of health services.
In the modern day scenario, chest pain and other related symptoms might signify ‘Acute Myocardial Infraction’ (AMI). This syndrome is highly associated with heart attack and atherosclerosis, a disease which has a negative impact on blood cell.
According to the British Heart Foundation, beta-blockers block the action of certain hormones (i.e., adrenaline) that increase the rate and force of heartbeat. In detail, the blockade of beta-1 receptors slows down the heart rate, reduces myocardial contractility, and lowers systemic blood pressure and it reduces oxygen supply also.
However, chronic obstruction may produce permanent loss of renal mass. and excretory capability, as well as enhanced susceptibility to local infection and stone formation. Early diagnosis and prompt therapy are therefore essential to minimize the otherwise devastating effects of obstruction on kidney structure and function.
In this process the macrophages are transformed into foam cells, which accumulate within the smooth muscle cell layer of coronary arteries to form plaque. Calcification of the surrounding tissue of the smooth muscle follows. The ensuing consequence of this
This research project investigates the extent of effects of stress on the heart and its capability to cause any heart disease or aggravate the condition of an existing heart disease. It details how stressors can start the development of one or more heart related diseases. The hypothesis to prove right or wrong is that stress causes heart diseases although not immediately but gradually, especially over the long term.
