Coronary circulation

immediately because it elevates blood pressure and prevents proper circulation of blood to all parts of the body. Specifically angioplasty can be divided into percutaneous coronary intervention, peripheral angioplasty, and renal artery angioplasty.2 Angioplasty is divided into these groups based on where the narrowed blood vessels are located. In percutaneous coronary intervention, also known as coronary angioplasty, narrowed coronary arteries, or vessels that directly give oxygen rich blood to…

MI is the significant damage and death of heart muscles caused by a compromised blood flow. When blood flow to the heart is blocked by a blockage of a coronary artery, oxygen delivery to the heart muscles is compromised as well. According to Macon and Yu (2012), most common recognized sings of an acute MI are: anxiety, cough, tachycardia, pain in the chest, back, jaw or other areas of the body, and shortness…

The blood leaving the heart during each contraction is done through the aortic and pulmonary arteries, thus transportation including the circulatory and coronary system, pulmonary, and systemic circulation must be working efficiently for the tissues to collect the proper nutrients (lecture 4). Blood pressure is considered as “the force that blood places on the walls of the blood vessels as it flows through them” (lecture5). The…

Introduction Coronary Heart disease is the expression that defines the blocked or interrupted of the heart's blood supply by a build-up of fatty substances in the coronary arteries. Over time, the walls of the arteries are stuffed with fatty deposits, which is called atherosclerosis and the fatty deposits are called atheroma (BBC 2013). Coronary Heart Disease (CHD) is a major killer in the UK as well as worldwide. It’s the cause of more than 73,000 deaths in the UK. Each year around 1 in 10…

1. Discuss the pathophysiology of coronary artery atherosclerosis. Include discussion of risk factors associated with the development of this disease. (10 points) Coronary artery atherosclerosis is most commonly comprised of atherosclerotic fibrous fatty obstructions of the large epicardial vessels, which provide for blood flow and transport nutrients, oxygen, and elimination of metabolic waste products such as CO2, lactic acid, and hydrogen ions. Coronary artery atherosclerosis is a…

between Venoarterial and Venovenous Extracorporeal Membrane Oxygenation. Venoarterial ECMO Venovenous ECMO Higher PaO2 is achieved. Lower PaO2 is achieved. Lower perfusion rates are needed. Higher perfusion rates are needed. Bypasses pulmonary circulation Maintains pulmonary blood flow Decreases pulmonary artery pressures Elevates mixed venous PO2 Provides…

that can occur due to multiple reasons including endocrine dysfunctions, diet, and mineral metabolism dysfunctions. In addition, vascular calcification can be linked to certain diseases such as arthrosclerotic ishemia, damaged brain circulation, and decreased coronary perfusion. Intradialytic hypotension is low blood pressure often due to hemodialysis. Some of the risk factors of acquiring intradialytic hypotension includes diabetes, age, and long lengths of hemodialysis. The point of this study…

drainage and later closed. One of the most common wounds at the hospital setting is surgical wound. It comes with many factors that delay wound healing such as; age – wounds in older patients heal more slowly than those younger, chronic diseases- coronary disease, diabetes and other chronic…

Tobacco has long been a recreational drug consumed in many ways by people. One form of tobacco product includes cigarettes—narrow shaped tubes that hold a dry substance laced with a large number chemicals. Cigarettes are available in a variety of sizes and flavors packed in hand-sized carton boxes or bags. To activate a cigarette, a person places a stick between their lips and lights the brown tip of the stick with fire while sucking the white end until smoke rises. When the smoke is inhaled,…

of pacing the coronary heart rhythm from ventricular conduction device, the price slows right down to 30-40/min and QRS complexes on the ECG are wider than 120 ms. In ventricular traumatic inflammation the depolarization of cardiomyocytes is caused by several mechanisms – reentry, induced hobby, ectopic foci of excitation or mixture of these. In ventricular traumatic inflammation (VF) the heart paintings is useless, fibrillating ventricals are not pumping blood and the circulation stops. As an…
