Queen of Hearts

Myocardial infarction (MI), also known as heart attack, occurs when there is a complete occlusion of a coronary artery that causes ischaemia and death to the muscles in an area of the heart. In 2014/2015, MI was the main cause of 54,000 hospitalisations in Australia. Additionally, it is estimated that over 400, 000 Australian have suffered a heart attack at one point in their lives. In general, men are more at risk of MI than women. Also, men tend to experience MI almost 10 years earlier…

pediatric OR nurse specializing in open heart surgeries, I immediately asked myself whether our patients undergo the same thing when they receive prophylactic vancomycin dose and then later go through cardiopulmonary bypass (CPB). Vancomycin is given as an antibiotic prophylaxis to patients undergoing cardiac surgery. CPB is an extracorporeal circulation technique that delivers blood flow and oxygen to the body tissues during a surgery that requires the heart pumping action to be stopped…

Aortic graft infection is rare and carries a poor prognosis. The conventional managements for prosthetic graft infection are surgical debridement, removal of the infected graft, and reconstruction with the new graft prosthesis. However, these approaches are not feasible for some patients with anatomical difficulty of excision or severe comorbid medical illnesses. We report a case of aortic prosthetic graft infection treated successfully with long term antibiotics without surgical intervention. A…

You're alive…. I am alive… But there is a problem with that. Well, how to I say this without being disgusting? Umm…. As a normal human being, we all produce waste. This waste comes from cells, as metabolic waste. This includes excess carbon dioxide, salts, and urea. Urea is a toxic compound that is produced when amino acids are produced. And that waste leaves our body. The system that gets rid of that waste is the excretory system. This system is consisted of the skin, lungs,the kidneys, and all…

The heart muscle itself has its own set of arteries, capillaries, and veins, as does every other organ in the body. They are called the coronary arteries and veins since they encircle the heart. Coronary arteries are supplied with oxygenated blood from the aorta to the myocardium to keep contracting. The left coronary artery feeds most of the left ventricle, the septum and much of the conduction system. The right coronary artery feeds the right side of the heart, including the sinoatrial (SA)…

Degenerative Disease may also affect the central nervous system, bones, blood vessels or heart. In this case the two diseases I have chosen to discuss are Heart Disease and Osteoporosis. I believe that our body composition is a uncertain issue many…

Cystic Fibrosis Part 1 Jenna Saline Kaplan University Cystic Fibrosis is a genetic condition that has an affect on many organs of the patient. This disease will ultimately lead to fatal impairment of the lungs. It is most common to see Cystic Fibrosis diagnosed from early childhood to young teens. Cystic Fibrosis is an autosomal recessive disorder in which both gene alleles must be mutated for the disease to be expressed (Ignatavicius and Workman, 2013). As every person…

Have you ever had heart surgery, or any surgery of any kind? I have had heart surgery three times in my life. The reason for the first to was that I had outgrown my current donor. When I was born my Pulmonary Valve for very small, to small to let blood through. The Pulmonary valve allows blood to go to the lungs and get oxygen, so it is a very important part of the heart. Mine was too small, so blood would have clotted behind it and almost none of my blood would have got oxygen to carry…

An increasing body of experimental evidence suggests that lung/kidney interactions are involved both in AKI-associated acute lung injury (ALI) and renal consequences of acute respiratory failure. Positive pressure ventilation, changes in PaCO2 and PaO2 levels along with systemic inflammation participate in the renal response to acute respiratory failure. Positive pressure ventilation may modify venous return, cardiac after-load and may decrease cardiac output along with decreased renal blood…

found by multiplying the heart rate and stroke volume. Increasing the heart rate would increase the cardiac output. Sympathetic stimulation releases NE and this shortens repolarization and speeds up depolarization, which increase heart rate. An increase in venous return causes the heart rate to increase by stretching the nodal cells, and the force of contraction increase, and this increases the stroke volume. The parasympathetic stimulation releases ACh, which slows down the heart rate. 21. If…
