Heart

The heart is one of the busiest organs in the body. It pumps liters of blood non-stop during an animals's entire live, and any damage to its physical condition tends to be fatal. Myocardial infarctions are common and come in varying levels of severity. At their worst, they cause irreversible damage to the heart's tissue, jeopardizing the whole machinery. Currently, there is no way to restore lost heart function after a devastating heart attack in humans because the damaged tissue cannot be…

threatening conditions is heart failure. The heart is a muscular structure that pumps blood to all parts of the body. Heart failure results when the heart fails to pump enough blood hence increased overload. The pathophysiology occurs as a result of increased workload on the left ventricle especially in patients with hypertension. This leads to enlargement of the muscles; enlarged muscles lack sufficient oxygen supply due to reduced supply of coronary artery to the muscles of the heart. Patients…

scatter plot above, the readmission rates from Pneumonia and Heart Failure has a positive correlation relationship. Both variables move in the same direction. In other words, as one variable increases, the other variable will also increase. As one variable decreases, the other variable will also decrease. Therefore, this means that Pneumonia and Heart Failure are positively correlated. Not only that, the readmission rates from Pneumonia and Heart Failure also have a strong relationship. As the…

Why is this drug used? Lisinopril is used to treat heart failure, high blood pressure, and to assist in the survival in patients who may have had a heart attack. It is in a class of drugs called Angiotensin Converting Enzyme blockers (ACE). This drug works by reducing certain chemicals that squeeze the blood vessels, so that the blood can flow smoother and the heart can pump the blood better. (U.S. National Library of Medicine [NLM], 2015) Dosage Forms It is in a tablet form of 2.5 mg, 5 mg,…

Heart failure is a cardiovascular disorder. Heart failure occurs when the heart is incapable of pumping blood around the body efficiently, therefore is unable to meet the body’s needs for blood and oxygen. There are differing types of heart failure, chronic and acute heart failure being the most common (4). This essay will give a brief background on heart failure, the casual agents of heart failure as well as risk factors, testing and appropriate treatment strategies. Heart failure is a serious…

there are many heart diseases, some can happen because of high cholesterol. High cholesterol blocks the flow of blood in the veins causing Heart attacks. there are two types of Cholesterol, Good and “Bad” Cholesterol, and “Good” Cholesterol. Rheumatic heart disease is caused by one or more Rheumatic attacks, this will cause damage to the heart. Specifically to the heart valves. This fever normally occurs during childhood. A streptococcal infection will ensue, which is what will generally…

Problem: For this procedure we tested are heart rate to see how it changed depending on what level activity we did. Heart rate is when the heart contracts because it is pumping the oxygenated blood through the aorta. Then the blood goes through your heart through the vena cava. Once you start moving the blood go through the capillaries to your lungs, legs, head and arms the blood flows through the inferior and superior capillaries. The part of the heart blood that that keeps the blood from…

analyse and observe the role that exercise plays in affecting the blood pressure and heart rate of a patient, with and without the consumption of caffeine. In this experiment, a cycle ergometer (Monark 824E, Monark Exercise, Sweden) was used in an incremental style type exercise that measured the fourteen healthy participants blood pressure and heart rate at various interval stages. The blood pressure and heart rate were recorded in order to obtain an understanding of the impact this would have…

The heart is considered the “engine of life” through its ability to rhythmically pump oxygen rich blood throughout the body to supply life. Unfortunately, this vital organ is vulnerable to damage through actions of everyday life ranging from smoking, diet, physical inactivity, and consumption of alcohol. Damage to the heart results in heart disease, also known as cardiovascular disease. Because of the vast complexity of the heart, heart disease branches off into various categories including…

is the size of your fist Heart disease is the number one killer in the United States. The term Heart Disease is used to label a range of diseases that affect the heart; heart failure and coronary artery disease- are a few of many serious heart problems. According to the National Heart, Lung, and Blood Institute, their research suggest that heart disease begins with damage to the lining and inner layers of the coronary (heart) arteries. The buildup of plaque in the heart arteries may even start…
