The Failure Of Heart Failure - 999 Words

The human body requires a supply and demand process within itself to enable nutrients and oxygen to provide homeostasis and metabolic demands throughout each organ system. The most prominent organ effecting this process is the heart, which by using the cardiovascular system supplies every other system throughout the body with the oxygen and nutrients by pumping them throughout the blood. When the demand is not met or the supply is too great it can be considered heart failure. Understandably heart failure is a worrisome term. To think one of your most vital organs is failing and unable to provide what is needed for basic survival is terrifying. However; there are many stages of heart failure that can range from mild to severe. Therefore,†¦show more content†¦Class 2 is classified when a patient has only slight limitations of physical activity but they are comfortable at rest. Class 3 is considered when a patient has marked limitations of physical activity and is broken down into 3A which is when a patient is comfortable at rest or 3B when they have dyspnea at rest. Class 4 is when the patient has symptoms at rest, the patient is unable to perform any physical activity without having discomfort. Stage D is considered Class 4 and is end stage heart disease that requires treatment. Information obtained from Jaski, Brian E. 2015. The 4 Stages of Heart Failure Left-Sided Versus Right-Sided Heart Failure There are two main types of heart failure. Left sided heart failure and right sided heart failure. The left ventricle is the largest chamber of the heart, and is also the most common site that fails in heart failure. When the left ventricle starts to fail it allows the blood that is normally pumped out into the circulatory system to back up into the left atrium due to the weekend left ventricle not pushing all the blood out. This leads to a cascade of events that lead to a backup in the pulmonary system allowing fluid to accumulate in the lungs which in turn causes shortness of breath. Right sided heart failure is less common than left sided heart failure and is usually caused by the problems associated with left sided heart failure over time. When the rightShow MoreRelatedThe Failure Of Heart Failure1517 Words   |  7 PagesABSTRACT Heart failure is one of the leading causes of mortality, both globally and in New Zealand. It is defined as the inability of the heart to meet the bodies metabolic need for oxygen and is characterised by a decrease in cardiac output. The body has many intrinsic mechanisms to attempt to maintain cardiac output, including activating the renin-angiotensin-aldosterone system (RAAS). The RAAS cascade acts to restore cardiac output by increasing fluid retention, thus increasing blood volume andRead MoreHeart Failures Of Heart Failure782 Words   |  4 Pages Heart failure describes a medical condition when the heart is unable to pump sufficient blood to the body [85]. While heart failure does not mean the immediate stopping of the heart, it is a serious and fatal condition. A study has found that the 4-year mortality rate for chronic heart failure was 43% for patients with preserved systolic function, and 54% for patients with reduced systolic function [86]. Heart failure is prevalent, wi th about 2-3% of adults worldwide showing signs of heart failureRead MoreThe Failure Of Heart Failure2760 Words   |  12 PagesCongestive heart failure, also called heart failure or CHF, is one of the fastest-growing syndromes in the United States and worldwide. It is a condition with high hospitalization and high mortality rates as well as a compound medical regimen that significantly affects the patient’s lifestyle and that of their family. The term alone, â€Å"heart failure†, is enough to scare the bravest client and cause the rise of numberless concerns and questions. Patients may worry and exclaim, â€Å"Did my heart stop workingRead MoreFailure Of Congestive Heart Failure1262 Words   |  6 PagesIntroduction Almost every one in the United States knows a person suffering from congestive heart failure. This disease has manifested its way into the lives of so many—the statistics are astounding. According to the National Heart, Lung and Blood Institute, nearly 5 million people are affected and it is the main reason for hospital admission in older adults over the age of 65. This is a great cause for concern. In order to reduce the morbidity and control this epidemic, we must first understandRead MoreFailure Of Congestive Heart Failure1149 Words   |  5 Pages Introduction Congestive Heart Failure is the Inability of the heart to maintain the demands of pumping blood with normal efficiency to other organs, such as the brain, liver, and kidneys (Congestive heart failure, 2008). Without the heart carrying out its functions, all the organs in the body would be deprived of sufficient blood to do its work, the kidney will no longer filter its blood leading to fluid accumulation in areas such as the lungs, liver, legs, and surrounding eye, when thisRead MoreThe Heart Of Heart Failure1167 Words   |  5 PagesAmericans have been diagnosed with heart failure† (Mancini Colombo, 2015, p. 2542). Heart failure is a condition where the heart does not pump as efficiently; therefore, it does not meet the needs of the body. There is a growing number of heart failure patients each year. â€Å"More than 300,000 deaths per year are attributed to heart failure, and the annual cost to manage these patients is close to $40 billion† (Mancini Colombo, 201 5, p. 2542). Since the heart failure population is steadily growingRead MoreCongestive Heart Failure And Failure1389 Words   |  6 PagesIntroduction Congestive heart failure (CHF), also called chronic heart failure or congestive cardiac failure (CCF) is a clinical condition where heart muscle is weakened and cannot pump the blood as well as the normal heart. The ventricle, also known as main pumping chamber of the heart become larger or thicker which leads to inability to contract or relax as it should. â€Å"There is no universally agreed definition of heart failure (Denolin et al., 1983). It is the consequence of cardiac disease, diagnosisRead MoreFailure Of Congestive Heart Failure2459 Words   |  10 Pagesincreasing frequently (Drug Store News, 1997). Congestive heart failure tends to be more common in the elderly, men, and also African Americans. Congestive heart failure has become the most common cause for current hospital admissions. Among causing prolonged hospital stays congestive heart failure has a very high mortality rate, which has declined since recent medical advancements. So what is congestive heart failure? A simple definition is the heart s inability to pump blood to the rest of the bodyRead MoreFailure And Treatment Of Heart Failure2085 Words   |  9 PagesAbstract: Heart failure affects over 5 million people and carries a high rate of mortality. Ivabradine, a new agent has been added to the current medical options for managing heart failure. It is a selective inhibitor of sino-atrial node and slows its firing rate, prolonging diastolic depolarization without any negative inotropic effects.

Readmission rates after hospitalization also remain high, with 50% of patients being readmitted within 6 months of discharge. (Desai Stevenson, 2012). The Affordable Care Act penalizes hospitals with readmissions within 30 days after discharge, making readmissions a focus of hospitals nationwide. Several factors including discharge planning, patient education, diet restrictions
