Beta Blockers After Myocardial Infarction Clinical Scenario The acute care nurse practitioner on the cardiology service treats a 67 year-old-male admitted after recovering from an acute ST-Elevation Myocardial Infarction (STEMI). His risk factors include obesity, Type II diabetes mellitus, and family history. Upon exam the patient asks why he has not been started on a beta blocker yet. He explains further that when his brother had a “heart attack” in 2005, he was immediately placed on a beta blocker because the cardiologist reported how beta blockers reduce mortality after myocardial infarction (MI). The patient wants to know if a beta blocker would reduce his chance of mortality? Using the Patient-Intervention-Comparator-Outcome (PICO) format we formulated the following question. In a 67-year-old male with multiple co-morbidities with MI (P), does treatment with a beta blocker (I), compared with no beta blocker or placebo (O), reduce mortality rate (O)? Risk Factors, Incidence and Prevalence of Disease * US incidence rates of cardiovascular disease, including MI, are seen in men more than women (Alexander et al., 2007). This trend is also true in Utah ("Impact of heart," 2007). * The incidence rates of cardiovascular disease increase with age (Alexander et al., 2007). * Risk factors for cardiovascular disease include not eating enough fruits and vegetables, lack of physical exercise, smoking cigarettes and the co-morbidities of diabetes, hypertension, hyperlipidemia, and obesity ("CDC national heart," 2010). * The clinical scenario patient was at high MI risk being male, over 65, diabetic and obese.
Article Critiques * The following primary article critiques were based on the CONSORT statement (2010). Primary Article One Article selection and evidence. * The article by Chen et al. (2005) was selected because it was the only

...HEALTHCARE Name Professor’s name Institution affiliation Course title Communication is the transmission of information between people objectively. It is quite important in the professional development of an individual as it determines the extent to which lasting relationships are built. Face to face talks have served to establish trust in the content of information communicated and helped to build warm relationships among frequently communicating people. Effective ways of expressing oneself like maintaining eye contact and identifying body language coupled with good listening skills would easily allow a doctor to ascertain the symptoms of a patient easily and further diagnose the patient accurately. Listening involves recognizing the words, understanding their meanings, distinguishing facts from fantasy and empathizing with the speaker. To listen well, focus on the content of the message and not the messenger; think while listening; seek clarification when necessary; and check out for non-verbal cues. The transition from hearing of information to its understanding and a gain of insight on the exact matter at hand defines the habits of a good communicator. If used effectively, communication can help attain various goals such as discovery, presentation of ideas, development of relationships, and creation of influence.An effort to eliminate communication barriers such as time deadlines, culture, linguistic barriers and relationship barriers can also come in handy...

...Running Head: ANXIETY IN SMOKERS AND NONSMOKERS Research Critique: Anxiety in Smokers and Nonsmokers with Acute Myocardial Infarction Research Critique: Anxiety in Smokers and Nonsmokers In November 2006 the American Journal of Critical Care published a research article comparing anxiety between smokers and nonsmokers with acute myocardial infarction. This study compared various demographic areas to various treatment modalities pertaining to both smokers and nonsmokers admitted with a diagnosis of acute myocardial infarction (AMI). Background The background section of this study was clearly identified. There were clear statistics listed within the background that gave specific numbers of persons affected by acute myocardial infarctions. This study was chosen because “no studies comparing anxiety levels between smokers and nonsmokers hospitalized for an AMI have been reported” (Sheahan, et al., 2006). This study is important to nursing due to the fact that anxiety levels are inherently increased when patients are faced with difficult situations, however when a person who is more prone to anxiety faces a difficult situation the anxiety level is increased over normal values. There were several articles over five years old however they appear to be focused on aspects directly linked to this study. The specific research questions addressed in this study were clearly and directly stated in understandable language. These questions and...

Pathology

...Pathology: Myocardial Infarction Name University Objectives 1. Discuss myocardial infarction and its pathogenesis. 2. Describe the sequence of changes involved in myocardial infarction. 3. List the major physiologic and morphologic complications of myocardial infarction. 4. Describe management of myocardial infarction. 5. Discuss patient teaching of myocardial infarction. Definition Myocardial infarction (MI), commonly known as a heart attack, is an irreversible necrosis of the heart muscle secondary to prolonged ischemia. This usually results from an imbalance in oxygen supply and demand, which is most often caused by plaque rupture with thrombus formation in a coronary vessel, resulting in an acute reduction of blood supply to a portion of the myocardium. (Zafari, 2011) Etiology The etiology of MI is predominantly from atherosclerosis i.e. coronary artery narrowing due to plaque formation. Non-modifiable risk factors for atherosclerosis includes: age, sex, family history of premature coronary heart disease, etc. Modifiable risk factors for atherosclerosis includes: smoking or other tobacco use, diabetes mellitus, hypertension, hypercholesterolemia, hypertriglyceridemia, obesity, sedentary lifestyle and/or lack of exercise, psychosocial stress, poor oral hygiene, etc. Non-atherosclerotic causes of MI include the following: • Coronary occlusion secondary to vasculitis • Ventricular hypertrophy (e.g., left ventricular hypertrophy, idiopathic hypertrophic...

Myocardial Infarction Case Study

...Back Ground: Despite impressive strides in diagnosis and management of acute myocardial infarction in the past three decades, acute myocardial infarction continues to be a major health problem. About 50% of death from acute myocardial infarction occur within 1hr of the event and are attributable to arrhythmias most often ventricular fibrillation. Ischaemic injury can produce conduction blocks at any level of the atrioventricular or Intraventricular conduction systems. Such conduction block can occur in the atrioventricular node producing various grades of AV block. Conduction block can occur in either main bundle branch producing right or left bundle branch block or in the anterior and posterior fascicle of left bundle branch, producing left anterior &left posterior...

Women and Heart Disease

...Women and Heart Disease Coppin State University Abstract Heart disease is a leading cause of death for women and men worldwide. Women are more vulnerable to myocardial infarction because of the size of their coronary arteries. They have unique risk factors such as a high level of cholesterol, hypertension, and smoking that cause heart disease, which leads to the high mortality rate. To reduce the high mortality rate among women, nurses must play their roles as educators because they interact frequently with patient, moreso than any other health care workers. Nurses must educate their patients on how to prevent the risk factors of heart disease. In order to reduce the high mortality rate due to MI in women, the Obama administration implemented the Patient Protection and Affordable Care Act (PPACA), popularly called t "Obama Care". This policy has mandated that insurance companies cover important preventive care at no cost, which will help eliminate the expensive bills that would have been incurred. As a future nurse, I would address the issue of heart disease by providing qualitative education and creating awareness of the causes and preventive measures of heart diseases. Keywords: Affordable Care Act, Heart Disease, Myocardial Infarction, "Obama Care", and Women's Health. Introduction Although both men and women have increased mortality rates due to heart disease in the United States, women have the higher rate and carry a heavier cardiovascular burden...

SACK, M.D. Medical University of South Carolina, Charleston, South Carolina Atrial fibrillation is the arrhythmia most commonly encountered in family practice. Serious complications can include congestive heart failure, myocardial infarction, and thromboembolism. Initial treatment is directed at controlling the ventricular rate, most often with a calcium channel blocker, a beta blocker, or digoxin. Medical or electrical cardioversion to restore sinus rhythm is the next step in patients who remain in atrial fibrillation. Heparin should be administered to hospitalized patients undergoing medical or electrical cardioversion. Anticoagulation with warfarin should be used for three weeks before elective cardioversion and continued for four weeks after cardioversion. The recommendations provided in this two-part article are consistent with guidelines published by the American Heart Association and the Agency for Healthcare Research and Quality.

About Anaphylaxis

...About Anaphylaxis Anaphylaxis can be defined as a life threatening and sometimes fatal allergic reaction. It is an allergic reaction that involves several organ systems simultaneously. When you are experiencing this severe reaction, symptoms will manifest in the lungs, skin, throat, nose, or gastrointestinal tract. This type of allergic episode is sometimes called anaphylactic shock, although you may experience this severe allergic event without going into shock, and this would entail a precipitous drop in blood pressure. Anaphylaxis usually occurs after an individual has been initially exposed to an allergen. After that first exposure, the person becomes highly sensitized to that particular allergen. When they are exposed once again, a dangerous allergic reaction will occur and this usually happens within minutes. There are numerous allergens that may cause a person to experience anaphylaxis. These can include: insect bites, drugs such as vaccinations, foods like peanuts or shellfish, or chemicals like latex. Note that peanuts and tree nuts alone are responsible for about 80 percent of all fatal reactions. In some cases, physical exertion has shown to be a contributing factor in this condition. Symptoms There are many different symptoms that one can exhibit during an experiencing anaphylactic episode. Some of these would include: difficulty breathing, dizziness, coughing, hives, stomach pain, cramping, anxiety, confusion, diarrhea, nausea, vomiting, wheezing, a blocked...

The Document

...provide adequate perfusion to the body. This occurs due to other conditions or diseases such as chronic hypertension or a previous myocardial infarction. Clinical findings may include a decreased blood pressure, dizziness, or signs of hypoxia. The body senses this decrease in cardiac output and attempts to maintain homeostasis. Baroreceptors detect inadequate pressure and norepinephrine is released by the adrenal gland. This causes profound vasoconstricion, as well as an increase in inotropy, chronotropy, and dromotropy. This just means that the heart is beating faster and harder due to the catecholamine release. The kidneys also lend a hand by releasing Angiotensin Converting Enzyme, or ACE. ACE converts angiotensin I into angiotensin II, which is yet another vasoconstrictor. The body will also act to increase volume by inhibiting fluid release. The heart itself produces a peptide called Brain or B-type Natriuretic Peptide (BNP). All of these compensatory mechanisms acting together cause the cardiovascular system to go into overdrive. Too much vasoconstriction and cardiac force cause increased afterload. Afterload is the pressure in which the heart is pumping against. This is also known as arterial pressure and an increase results in an increase in palpable blood pressure. Since the heart can’t pump blood out efficiently against the increased after load, blood backs up. It first backs into the atria from the left ventricle. It then backs up into the pulmonary vein and then the...

Treatment of Congestive Heart Failure

...failure usually develops slowly, often over years, as the heart gradually loses its pumping ability and works less efficiently. CHF affects individuals in different ways and to different degrees. It is usually a chronic disease and gradually becomes worse over time. Many people are not even aware of their condition until symptoms appear years after the heart began its decline. There are many causes, risk factors, and signs & symptoms that help determine if someone is at risk of developing CHF or already living with CHF. Nearly 500,000 Canadians are currently living with the condition, with 50,000 new cases diagnosed each year. With such high numbers of people diagnosed with CHF, I believe as a future nurse it will be beneficial to have a greater understanding as to how CHF develops, how it is treated, and how it is management. Etiology The etiology of CHF can vary significantly from person to person. As heart function is a measure of preload, contractility, and after load the etiology of CHF include causative agents that effect one or more of these three variables. These agents include coronary artery disease, myocardial infarction, myocarditis or endocarditis, heart valve disorders, arrhythmias, pulmonary hypertension, pulmonary...

Essay On Coronary Artery Disease

...Coronary artery disease is usually caused by atherosclerosis. Cholesterol and other fatty substances accumulate on the inner wall of the arteries. This attracts fibrous tissue, blood components, and calcium, which harden into flow-obstructing plaques. If a blood clot suddenly forms on one of these plaques it can convert a partial obstruction to a total occlusion. When the blockage is temporary or partial, angina (chest pain or pressure) may occur. When the blockage completely and suddenly cuts off the flow of blood, the result is myocardial infarction. Congenital defects and spasms of a coronary artery may also block blood flow. There is evidence that infection from organisms such as chlamydia bacteria may be responsible for some cases of coronary artery disease. A number of major contributing factors increase...
