Myocardial Infarction And Cardiac Arrest Essay

The priorities are to detect intraoperative MI early, give effective treatment, and transfer the patient to ICU urgently for further cardiac care. [10] When myocardial ischemia is because of hypovolemia, hypotension should be primarily managed with IV fluids in the form of crystalloids or colloids and blood products. Inotropic support is required when there is no response to fluid administration. In this case myocardial ischemic changes were because of hypovolemic shock. Hence by correcting hypotension secondary to hypovolemia the myocardial ischemic changes were reversed.

Myocardial perfusion imaging: Myocardial perfusion imaging (MPI) is a form of functional cardiac imaging, used for the diagnosis of ischemic heart disease. The underlying principle is that under conditions of stress, diseased myocardium receives less blood flow than normal myocardium. MPI is one of several types of cardiac stress test. A cardiac specific radiopharmaceutical is administered.

This type of shock occurs when the heart is unable to pump blood effectively. This is evident to patients who have had myocardial infarction, such as John’s case. In this illness, the heart has decreased contractility resulting to decreased cardiac output. Such decrease will stimulate the sympathetic nervous system to activate the compensatory mechanism by increasing the heart rate as evident in John’s vital sign to increase the peripheral pressure and ventricular

AH314-Pathophysiology Case Study 4 Myocardial Infarction K.R. is a 46-year-old man admitted to the emergency department with unremitting chest discomfort. The pain started while he was shoveling snow from his walkway. He had experienced chest discomfort with activity previously, but the pain had subsided with rest and he sought no medical help. This time the pain did not subside and became increasingly severe, radiating to his left arm and lower jaw. In the emergency department, an ECG and cardiac enzymes were obtained.

UpToDate: Prior to diagnosis it is important to define the severity of idiopathic pulmonary fibrosis (IPF). According to UpToDate, mild disease is often asymptomatic or very mild, moderate disease includes dyspnea on exertion, and dry cough, and decreased pulmonary function tests, and severe disease is characterized by dyspnea on mild exertion and the need for supplemental oxygen. Treatments include supportive care which involves supplemental oxygen when needed, vaccinations against influenza and pneumonia as these are not tolerated well in IPF patients, patient education, and pulmonary rehabilitation. There are some medications that are available that are being tested in clinical trials or already available to patients. These include Nintedanib and Pirfenidone.

FIG : NORMAL HEART FIG : HYPERTROPHIC HEART (Hypertrophic cardiomyopathy,Cleveland clinic) Above figure in the left shows physiology of the normal heart while the right one shows physiology of hypertrophic heart having leaky mitral valve, thickened septum and narrowed outflow tract. Symptoms of hypertrophic cardiomyopathy: (Marian Ali .,2010) • Arrhythmias: This condition mainly occurs when heart rhythms of the patient are irregular due to improper flow of blood from the heart to rest of the body.

A treatment option for those who have suffered an ischaemic stroke is thrombolysis. As 85% of strokes are ischaemic this is a treatment option for many (Fitzpatrick and Birns,2004).The goal of thrombolysis is to disintegrate the thrombus/embolus occluding the vessel and reduce the scale of tissue damage (Fitzpatrick and Birns,2004).It is important to note that thrombolysis using ateplase should only be used to treat acute ischaemic stroke once intracranial bleeding has been ruled out by diagnostic imaging, and within 4.5hours of onset by

Today, I will share to you the Ischemia Heart Disease. The Ischemia Heart Disease has been one of the most deadliest disease known for almost 2 decades (20 years). This disease can kill anyone in just one heart stroke. The main idea of this disease is that you get a heart attack due to the fact when plenty of your veins start to fill up of plaque and blood or as known as a blood clot, you get a heart attack. The blood flow and oxygen flow is incorrect or in simple words, the current of blood stops flowing through you body correctly.

These stresses cause a pressure overload which induce changes in myocardial structure and function. This initially acts a compensatory mechanism but when pressure overload persists it can lead to the development of cardiac hypertrophy (Lyon et al. , Mechanotransduction in Cardiac Hypertrophy and Failure) . Cardiac hypertrophy is strongly associated with in an increased risk of several severe cardiovascular events, including stroke, coronary heart disease and heart failure (Gosse,

Falls account for a majority of the injuries to patients in long term care facilities. With falls being such a prevalent problem in the geriatric population it is important for nurses to take into account many different aspects of the problem and make it a priority to reduce and even eliminate the problematic issue with the long term care setting. Nurses should be most concerned first about the safety and well being of their clients, injuries, lasting disabilities, and costs associated with the falls. “Falls account for a significant portion of injuries in hospitalized patients, long term care residents, and home care recipients. In the context of the population it serves, the services it provides, and its environment of care, the organization

25 medical words pertaining to the blood, lymphatic and cardiovascular system. 1. Hypercalcemia is a condition where the blood contains too much calcium. 2. Myoglobin is a type of protein that transport oxygen to the muscle.

The purpose of the Sheep Heart Dissection lab was to take a look at the heart's anatomy and all the parts that it consists of. This lab helped us learn how the heart is able to function, and gave us a hands on look at what a real heart looks and feels like. I worked on this lab with Jose, and Alex. We completed the procedure in one day of class, and had the questions completed by the second.

Purpose The purpose of the lab is to dissect a pig heart in order to identify all of the parts of main chambers, valves, and vessels. To able to know the circulation the blood through the heart to the lungs and identify each section of the pig heart. The pig heart has four chambers which it is two atria and two ventricles. They both pump the blood and give the body what it needs.
