Coronary circulation

plaque and become more prone to blood clots. Sometimes plaque or a blood clot can completely close an artery, blocking the blood flow to tissue on the other side. When a blockage cuts off the blood supply, part of the heart muscle supplied by that coronary artery is deprived of blood this is when a heart attack occurs (Heartorg, 2016), which was experienced by…

and modifications were invented. However, the ultimate goal of all different procedures is to achieve near complete separation of pulmonary venous return from systemic venous return. As such, all systemic venous circulation will be directed to the Fontan circulation (except the coronary sinus which continues to drain into the right atrium and when the Fontan is circuit is fenestrated) bypassing the heart [31]. Many investigators believe that routine pre-Fontan cardiac catheterization is…

decrease in the central retinal artery.1 In patients with an ICA stenosis, studies have shown that plasma levels of homocysteine and C-reactive protein are linked to the development of OIS.3 When ICA stenosis occurs, there is an incomplete blood circulation in the circle of Willis and ophthalmic artery blood flow reverses to provide the ipsilateral brain.4 This process is called “steal phenomenon” and if prolonged, it results in ocular ischemia with rubeosis iridis and neovascular glaucoma.4 OIS…

regular exercise has a positive impact on both Type 1 and Type 2 Diabetes as it improves blood glucose balance, it appears to be more beneficial to the people with Type 2 Diabetes. Regular exercise helps to reduce weight and to minimise the risk of coronary heart disease. Regular exercise increases insulin sensitivity and also improves glucose tolerance. Additionally regular exercise helps to relieve stress in people (Hillson, 2015,page 234). People who are very physically active have got a…

The Mechanics of the Heart An electrocardiogram, or EKG/ ECG, is a non-invasive test that measures the electrical activity of the heart and its electrical patterns. An electrical signal is sent through the heart to produce contractions that move the blood. This is what an EKG measures. In total that test may take from five to ten minutes and are ordered by a doctor to examine the heart more close. An EKG is done while the patient is lying down completely still (in order to reduce artifact or…

important part in any circulatory system. It provides the muscle power to transport the blood throughout the entire body, even to itself. There are arteries that supply the heart with blood, these are called coronary arteries.They are the bright red blood vessels in the heart. In a closed circulation system, animals possess hearts with distinct chambers. Fish have a two-chambered heart, the two cavities are called the atrium and the ventricle. Blood enters the heart through the atrium and then…

Heart Failure Even though heart failure is a chronic condition, acute or decompensated heart failures require ICU admission. Otherwise, patients already admitted to the ICU for other diagnoses may be affected by heart failure as a complication. Postmyocardial injury/postinfarction patients and postoperative patients are included in this category. To detect early heart failure or heart failure in compensated stages, ventricular filling pressures are evaluated against stroke volume. The ICU nurse…

atrioventricular septum. Differences between Left and Right Side of the Heart? • Left side of the heart operates at a level up to 125 mmHg, whereas the right side of the heart operates at 25 mmHg. • Right side drives a short, low pressure pulmonary circulation while the left side drives longer, high pressure systemic circuit. • Wall of the left side of the heart is thicker than that of the right side. • Right side circulates the deoxygenated blood while the left side circulates oxygenated…

occurs due to antheroscheloric plaque rupturing and distributing in the blood vessall. Substances that promote platelet aggregation and thrombus formation are then exposed in the blood streams which will eventually cause blockage of blood flow in the coronary artery . Patient’s medical history of hypertension is one of the most important risk factors of acute Myocardial infarction as the constantly high blood pressure can cause damage to artery endothelium and make her more vulnerable in…

Socioeconomic position is a financial and sociological joint whole measure of a person 's effort skill and of an individual 's or family’s financial and social condition in relation to others, stand on profits, education, and occupation. While breaking down a family’s SES, the family unit salary, workers ' education, and occupation are inspected, and additionally joined wage, versus with a person, when their own qualities are evaluated. Alternately all the more ordinarily know not a monetary…
