There are various treatments for acute coronary syndrome to prevent the occurrence of an acute myocardial infarction. The purpose of this essay is to discuss the current research of the pharmacological treatments of this condition and to evaluate the relevance of this research in relation to the practise of paramedics.
The term acute myocardial infarction is used when talking about myocardial necrosis in a setting consistent with myocardial ischemia (Steg, et al., 2012). Acute myocardial infarctions are the major cause of disability and death worldwide. Myocardial infarctions can be one of the first signs of acute coronary syndrome and they can also occur repeatedly in patients that have an ongoing coronary artery disease (Thygesen, et al., 2012).
Atherothrombosis is the pathophysiologic hallmark of acute coronary syndrome which can lead to an acute myocardial infarction. Platelet aggregation is one of the major reasons why ACS occurs, arterial plaque builds up over time from products such as lipids, cholesterol and fibrin. The vasa vasorum

It can take two to four hours or even longer for complete necrosis of the myocardial cell at risk. After a myocardial infarction it can take at least five weeks to heal the myocardium (Thygesen, et al., 2012). However if a patient goes into cardiac arrest the mortality outcomes for patients that have been resuscitated that were admitted to an intensive care unit are still high. Over the past decade in New Zealand and Australia patients admitted to the intensive care unit in regards to a cardiac arrest have remained relatively unchanged in over a decade as 46% of patients were admitted in 2003 and 48% of patients were admitted in 2012 (Eastwood, Schneide, Suzuki, Bailey, & Bellomo,
The primary concern for Mr. Miller would be preventing further ischemia and necrosis of the myocardial tissues, preventing serious complications such as cardiac dysrhythmias and heart failure, as well as relieving his chest pain that radiates to his left arm. Preventing further ischemia and necrosis of the myocardial tissue will help prevent the development of heart failure due to myocardial infarction, whereas relieving his pain will help reduce his episodes of shortness of breath, and will also help to reduce any anxiety and restlessness he may be having from being in pain and short of breath.
The purpose for the stent was to hold the coronary artery open to allow the blood to flow more freely.
It occurs because of repetitive electrical activity. This can occur in a patient with early or late heart failure, because there is damage to the heart tissue and the heart beats faster to try to supply the body with blood. Recommended treatment is elective cardioversion. Drugs used include an antidysrhythmic such as Mexitil or Sotalol (Ignatavicius &Workman, p. 728-729).
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
After review of the clinical information provided by North Central Bronx Hospital, the Medical Director has denied your admission to North Central Bronx Hospital. It was determined that the clinical information did not justify an inpatient stay. Acute inpatient hospitalization was not medically necessary. You are a 56 year old female with complaints of worsening pressure-like chest pain on the left sided that radiated to your left arm and neck. The symptoms began when you were at rest and woke you from your sleep. Based on the Interqual guideline (a decision based program to determine medical need) criteria to for acute coronary syndrome the clinical guidelines were not met because troponins were negative, there was no diagnostic testing such as a stress test, or documentation of ischemia in the clinical information that was submitted.
The American Heart Association gives sufficient evidence for the need of change by acknowledging that sudden cardiac arrest is a leading cause of death (2012). These fatalities affect both adult and child victims. Statistics also show that 70% of people feel helpless during a cardia...
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].
This assignment is a case study that aims to explore the biospychosocial impacts of a myocardial infarction on a service user. It will focus on the interventions used by healthcare professionals throughout the patient’s journey to recovery. To abide by the NMC’s code of conduct (2015) which states that all nurses owe a duty of confidentiality to all those who are receiving care, the service user used in this case study will be referred to as Julie. Julie is a 67 year old lady who was rushed to her local accident and emergency following an episode of acute chest pain and was suspected to have suffered from a myocardial infarction. Julie who lives alone reported she had been experiencing shortness of breath and
Recognition, response and treatment of deteriorating patients are essential elements of improving patient outcomes and reducing unanticipated inpatient hospital deaths (Fuhrmann et al 2009; Mitchell et al 2010) appropriate management of the deteriorating patient is often insufficient when not managed in a timely fashion (Fuhrmann et al 2009; Naeem et al 2005; Goldhill 2001). Detection of these clinical changes, coupled with early accurate intervention may avoid adverse outcomes, including cardiac arrest and deaths (Subbe et al. 2003).
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.
The term, ischemia, denotes inadequate blood supply to tissues due to blockage of the arterial inflow, while, reperfusion injury is defined as the injury caused by the restitution of blood flow after an ischemic peroid, leading to death of cells that were only reversibly injured at the time of blood flow restitution. [63]. The final infarct size after an MI event is therefore the result of the ischemic and reperfusion damage. For this reason, the term that best describes this process of myocyte death in reperfused MI is myocardial ischemia/reperfusion (I/R) injury [64]. In the early hours post myocardial ischemia, injured cardiac cells can release several molecules, including adenosine, opioids, and bradykinin, which activate the G protein signaling pathways therefore promoting myocardial survival. While in the late phase, myocardial ischemia induces upregulation of growth factors and cytokines, including VEGF, ILGF and SDF-1, in the injured myocardium, hence promoting a cardio-protective state. The liver also participates in cardioprotection through the up regulation and release of secretory proteins, including FGF21 and TFF3, which also promote cardiomyocyte survival. [65]. Foundational studies performed about three decades ago with animal models demonstrated that an early reperfusion was able to limit infarct size [66]. Then fibrinolysis was indisputably associated with a decrease in mortality in patients with STEMI [67].A decade later; primary angioplasty was shown to be more superior than fibrinolysis [68]. Currently primary coronary angioplasty (PCI) has been established as the backbone treatment for STEMI patients. The period from the onset of symptoms of MI (representative of the time of coronary occlusion) and reperfusio...
One of the leading causes of death in the United States is heart disease. “Approximately every 29 seconds one American will have a heart attack, and once a minute one American will die from a heart attack” (Ford-Martin and Odle, 915). According to the Gale Encyclopedia of Alternative Medicine men over the age of 45 and women over the age of 55 are considered at risk for heart disease. Heart disease is a major cause of death. It is beneficial to individuals who seek to prevent heart disease to recognize the risks leading to heart attacks as they are one of the primary indications of developing heart disease; especially those that fall into the at risk age groups. These risks consist of some that cannot be changed such as heredity risks, or those that can change such as smoking habits. It is very important to know these specific risks for prevention and to understand the symptoms of heart attacks, such as sweating or the feeling of weakness so if these or other symptoms occur people are aware. Finally heart disease treatment is of vital importance if you experience a heart attack so you can learn how to prevent another one from occurring.
Atherosclerosis, the underlying causes of coronary heart disease can affect any artery in the body. Coronary heart disease is essentially the build up of plaque which sticks to the walls of the coronary arteries. The arteries in atherosclerosis is narrowed due to the excessive build up of cholesterol-rich lipids known as plaque around the artery wall (Insull, 2009). Once the plaques around the walls of the arteries become narrow, the flow of blood will be constricted, reducing the amount of blood and oxygen that are able to reach the heart. Hence the heart becomes increasingly hypoxic, as a consequence the contraction become inefficient, thus poses serious cardiovascular complications which could result in heart attack (A&P p.687)(Insull, 2009). Despite the
Oxygen was first admitted to the client with chest pain over 100 years ago (Metcalfe, 2011). Chest pain is a large bracket that can contain many different conditions, but for the purpose of this analysis it is focused manly upon a myocardial infarction. A myocardial infarction is mainly referred to as a heart attack, and occurs when one or more coronary arteries leading to the heart reduce or completely stop blood flow (Tuipulotu, 2013 ). Administering high concentrations of oxygen to patients with chest pain is now embedded in guidelines, protocols and care pathways, even with a lack of clear supporting evidence (Nicholson, 2004 ). High concentration of oxygen means that up to 60% is administered (Knott, 2012). More recent research has suggested that the use of oxygen in this scenario is unnecessary and can lead to unwanted side effects, especially in normoxic cardiac patients (Moradkham & Sinoway, 2010 ). The aim of this comparative analysis is to dismantle and understand both the benefits and risks of the commonly known practice of administration of oxygen to the client with chest pain. Through completing this analysis using recent and appropriate evidence a more improved practice can be given and understood.
...heart attack. Heart Disease can refer to an assortment of diseases affecting the heart. A heart attack happens when heart muscle is destroyed or hurt due to not getting enough oxygenated blood to maintain life. Different examples of Heart Disease include Cardiomyopathy, Cardiovascular Disease, Hypertension, and Ischemic Hear Disease.
