Essays on Myocardial

Discussion

The term “heart muscle died” is associated with a clinical condition referred to myocardial infarction (MI) that simply means a heart attack. The process occurs due to the formation of a thrombus caused by plaque rupture in the coronary artery that leads to an acute reduction of blood supply causing an imbalance in oxygen supply and demand. The limit in oxygen supply and demand leads to a reduction in the volume of blood flowing into the myocardium, the muscle responsible for supplying blood to the heart (Zafari, 2017). Eventually, reduction in the blood flow to the myocardium causes an ...

Objective Data

Physical assessment procedures on the patient can help to identify some findings that can form a vital part of the pain diagnosis and influence treatment regimens. The following are some of the key inspections features that a health practitioner can seek out when assessing the patient according to “Chapter 8. Pain Assessment”;

Posture

The patient’s posture gives an insight into the effects of the pain on the physical aspects of the patient. An upright posture may indicate comfort while a slumped posture might indicate discomfort.

A total of 57 million deaths were reported worldwide in 2008, and the majority of those deaths were caused by either non-cardiovascular diseases (36 million; 63%) or cardiovascular diseases (17.3 million; 30%) according to the World Health Organization (WHO, 2011). The highest mortality rates are associated with ischemic heart diseases and cerebrovascular diseases, which account for 45% and 29% of the cardiovascular-related deaths in men and 37% and 33% of cardiovascular-related deaths in women, respectively (see Figure 1). Ischemic heart disease is considered the most common cardiovascular cause of death as it accounts for 7.6 million deaths worldwide (Institute ...

Main Risk Factors for Cardiovascular Disease

According to the World Heart Federation (WHF, 2016), the majority of cardiovascular disease (CVD)’s etiology stems from risk factors that can easily be controlled or managed or modified although a few other risk factors cannot be controlled. For that matter, the risk factors can be grouped into two broader categories (I) modifiable factors and (II) non-modifiable factors. For the modifiable factors, they include hypertension, cholesterol, unhealthy diets, obesity and overweight, physical inactivity, and the use of tobacco (WHF, 2016). On the other hand, the non-modifiable factors include age; the risk of CVD increases with age because as a ...

Introduction

Atherosclerotic cardiovascular disease (CVD) involves peripheral circulation, the brain, and the heart. The disease is a primary health issue in many countries around the world (Sawhney, et al., 2012). CVD develops through complex processes involving novel risk markers and common risk factors. Decades of research have demonstrated that a sibling’s or parent’s family history is linked to the development of atherosclerotic CVD (Gupta et al., 2013; Nelson, 2013; Imes and Lewis, 2014), which manifests as peripheral arterial disorder, stroke, and coronary heart disorder (CHD). Various Mendelian disorders have also been shown to contribute to atherosclerotic CVD. Although ...

Question 1: Pathophysiology of Mr. Jensen’s post-operative hypovolemia

Hypovolemia is a surgical condition that indicates the rapid fluid loss that may result in organ failures. The outcomes of the hypovolemia are mostly due to insufficient circulating volume or scarce perfusion. Often hypovolemia is secondary to hemorrhage the reason of which includes severe internal or external blood loss and GI, thoracic and abdominal bleeding maladies (Devitt, 2001). Hypovolemia involves significant fluid loss other than blood that can be further accompanied by refractory gastroenteritis and widespread burns. Hypovolemia may develop in post-surgical incidence, bone fracture, due to ...

Tele-Medicine in a Satellite Facility

Telemedicine is an old concept but new technology that enables a healthcare provider at one location to provide basic healthcare services such as diagnosis, intra-operative assistance, and medical consultation to patients, physicians or paramedical staff in a satellite or remote facility. Most researchers and scientist believe that there is no substitute for patient-doctor face to face interaction; however, telemedicine could be used to manage a few medical cases efficiently and remotely. In first prototype of telemedicine was introduced in the 1980’s in the form of slow-scan images, facsimile machine or telephone (Hsieh, & Hsu, 2012).The mode of communications ...

Abstract

The worldview of a person is their view and understanding of their entire existence, including the world they live in. Religious beliefs reflectcolor a person’s worldview very strongly. In a comparative look, Christianity and Sikhism have some commonality as monotheistic approaches to the world, in the necessity for moral and ethical behavior that is good, in seeking truth, and in serving an all-knowing God Wwho imparts some of that knowledge to mankind. However, there are noticeable differences in beliefs about death and afterlife, human definition, and the meaning of human history. These beliefs structure their worldviews ...

Basing on the laboratory values, the hemoglobin level of the Ms. A is lower than the normal value. Normally, the hemoglobin level lies between 12 to 17 grams per deciliter (Mader, 2004). The hemoglobin level of Ms. A was measured to be 8 grams per deciliter. Moreover, the hematocrit percentage, which measures the red blood cell concentration in the blood, of Ms. A is 32%, which is relatively low. For females, the hematocrit percentage should be around 36% to 46% (O’Leary, 2014). Furthermore, the erythrocyte count of Ms. A was determined to be 3.1 x 10^9 per ...

Monomorphic Ventricular Tachycardia

Cardiac arrhythmias often require immediate medical care that may include resuscitation (Ray, 2004). The diagnosis of cardiac arrhythmias can be challenging particularly in situations whereby the patient is asymptomatic and ECG findings are normal between symptomatic episodes (Cruickshank, 2008). Distinguishing between supraventricular and ventricular tachycardia is also a challenge (Australian Resuscitation Council, 2008). Cardiac arrhythmia should be suspected in patients with a history of syncope, near syncope, palpitations, and/or chest pain (Cruickshank, 2008). This paper will justify why monomophic ventricular tachycardia is the most likely diagnosis of a male patient who collapsed abruptly and has hypotension (BP 63/38), tachycardia ( ...

Discussion question

The heart tissues and muscles are designed in such a way that they continuously pump blood into and out of the heart. This implies that the cells within the heart muscles and tissues have to remain active for the nature lifetime in order to support the delicate mechanism of pumping blood. These cells however may reach a point where they cannot support the pumping of blood enough to sustain the required amount of blood in various parts of the body. In these instances, the heart muscles cannot contract strongly and well enough and this reduces the amount of blood ...

Cephalexin and Gentamicin The mechanism of action of amoxicillin is focused on the prevention of the synthesis of the bacteria’s cell wall through the binding and inhibiting of the cell wall transpeptidases (Katzung, Masters, and Trevor, 2012). Specifically, it attaches to the penicillin-binding protein 1A found in the cell wall of bacteria. Then, the agent disintegrates the lactam ring to allow the acylation of the penicillin-sensitive transpeptidase C-terminal domain. The formation of the cross-link of the linear peptidoglycan strands is prevented by the inactivation of transpeptidases. Since the third and last stage ...

The importance of percutaneous coronary intervention (PCI) as an integrated intervention for persistent coronary occlusion after myocardial infarction seems to have little indication of any improvements or positive benefits in the long term. When integrated with optimal medical therapy and stent placement there is little indication that in deed PCI affords the patients a higher chance of regression of coronary atherosclerosis (Hochman et al., 2006). In this regard, optimal medical therapy alone indicated significant benefits with particular reference to significant regression of coronary atherosclerosis for any period past the three years upon initiation of PCI. This in some sense ...

The following essay is going to review advantages and disadvantage of pre-workout compounds and anabolic-androgenic steroids (AAS) and their effect on athlete health. Pre-workout compounds and AAS are considered to be 2 major enhancers of athlete`s performance in short- and long-term respectively. Among large number of pre-work out compounds like NO-Explode (BSN), The Curse (Cobra Labs), Assault (MuslePharm), C4 (Cellucor), Jack3d is considered to be the most powerful pre-workout compound to be ever created. The difference between old and new mix of Jack3d (produced since 2012) is that older version of Jack3d included DMAA (1,3-dimethylamylamine). Just like ...

Acute coronary syndrome is an umbrella term for a group of clinical symptoms indicative of acute myocardial ischemia. These conditions include non-ST-segment elevation myocardial ischemia (NSTEMI), unstable angina, and ST-segment elevation myocardial infarction (STEMI). These conditions are high-risk manifestations of atherosclerosis in the coronary artery and significant causes of utilization of emergency services and hospitalization (Kumar and Cannon, 2009). STEMI causes 30% of all acute coronary syndromes in Australia (Harper and Lefkovits, 2010). This paper will describe the expected presentation, pathophysiology, ECG findings, pre-hospital management, and initial 24-hour management of STEMI in hospitals settings. These aspects will be described ...

Since the introduction of Antiretroviral Therapy (ART), the health prospect for the HIV-infected population has evolved considerably. The application of ART has led to a significant reduction in the rate of mortality for this group of people (Chastain et al., 2015). However, the number of deaths resulting from non-HIV-related diseases including cardiovascular diseases (CVD), hepatic disease, and cancer has taken the opposite turn. This paper evaluates the association between CVD and the administration of ART among HIV patients. A study in this area may be helpful in reducing the occurrence of CVD in the HIV-infected population. A prompt detection ...
