Heart failure (HF) is the inability of the heart to pump adequately to meet the metabolic needs of the body (Jeffrey et al, 2007). It is caused by structural or functional abnormalities of the heart (NICE, 2003). The reduced contractility leads to a reduced stroke volume, and therefore the heart rate is increased to help maintain cardiac output. HF can either be chronic where it has been occurring over time or acute, where it happens suddenly. Around 900,000 people in the UK have HF, with almost as many as damaged hearts but with no symptoms (Petersen et al, 2002). The prevalence of HF increases steeply with age, with the average age at first diagnosis is at 76. The risk of HF is greater in males than in females in all age groups, but there are more females than males due to population demographics (Eggett, 2014). The cost of general practitioner consultations has been estimated at £45 million per year, with an additional £35 million for GP referrals to outpatient clinics. In addition to this, community-based drug therapy costs the NHS around £129 million per year. The hospital admissions due to HF are understood to increase by more than half in the next 25 years, largely due to the ageing population. This paper will focus on comparing and contrasting the classic verves contemporary understanding of HF, evaluating both the traditional concepts and more recent developments of the understanding of this condition. Traditional concepts of HF The understanding of HF has
Heart failure may convey that the heart isn’t working anymore, but what it really means is that the heart isn’t pumping as well as it should be (REF). Heart failure is a chronic, progressive condition in which the heart muscle is unable to pump enough blood through to meet the body’s needs for blood and oxygen (REF). At first, the heart tries to make up for this by enlarging, developing more muscle mass, and pumping faster. As this happens, the blood vessels narrow to keep blood pressure up and the body diverts blood away from less important tissues and organs to maintain flow to the heart and brain (REF). Eventually, the body and heart cannot keep up and the patient begins to feel fatigue, breathing problems, weight gain with swelling in the feet, legs, ankles or stomach, and other symptoms that eventually leads to a hospital visit. The body’s coping mechanisms give us better understanding on why many are unaware of their condition until years after the heart declines (REF).
Heart failure is a chronic, progressive condition in which the heart muscle is unable to pump enough blood through to meet the body 's needs for blood and oxygen. Basically, the heart can 't keep up with its workload. American Heart Association Statistics (2016) reveals that heart failure accounts for 36% of cardiovascular disease deaths. Projections report a 46% increase in the prevalence of Heart Failure (HF) by 2030 by affecting over 8 million people above 18 years with the disease. Healthy People 2020 goals are focused on attaining high quality longer lives free of preventable diseases, promotion of quality of life, healthy development and healthy behaviors across all stages of life (Healthy People 2020, 2015).
Congestive cardiac failure, also known as heart failure, occurs when the heart is weak and unable to sufficiently supply blood the body needs to function. Heart failure can often be successfully treated with
Heart Failure is a progressive heart disease when the muscle of the heart is weakened so that it cannot pump blood as it should; the blood backs up into the blood vessels around the lungs and the other parts of the body (NHS Choice, 2015). In heart failure, the heart is not able to maintain a normal range cardiac output to meet the metabolic needs of the body (Kemp and Conte, 2012). Heart failure is a major worldwide public health problem, it is the end stage of heart disease and it could lead to high mortality. At present, heart failure is usually associated with old age, given the dramatic increase in the population of older people (ACCF/AHA, 2013). In the USA, there are about 5.7 million adults who have heart failure, about half of the people die within 5 years of diagnosis, and it costs the nation an estimated $30.7 billion each year (ACCF/AHA, 2013).
CHF can be caused by many different reasons. Sometimes CHF can be a heart defect or can be caused by unhealthy lifestyles. “CHF is an ongoing condition in which the heart muscle is weakened and can’t pump as well as it normally does” (Congestive Heart Failure). When the heart becomes too weak to continue to pump blood throughout the body, it is called Congestive Heart Failure. When CHF first
Heart failure affects nearly 6 million Americans. It is the leading cause of hospitalization in people older than 65. Roughly 550,000 people are diagnosed with heart failure each year (Emory Healthcare, 2014). Heart failure is a pathologic state where the heart cannot pump enough blood to meet the demand of the body’s metabolic needs or when the ventricle’s ability to fill is impaired. It is not a disease, but rather a complex clinical syndrome. The symptoms of heart failure come from pulmonary vascular congestion and inadequate perfusion of the systemic circulation. Individuals experience orthopnea,
There are many causes for heart failure. The most common cause is coronary heart disease (Moore and Roth, 2015). CHD is a disease in which the coronary arteries are blocked, preventing the heart muscles from getting the oxygenated blood they need. Heart failure can be caused by other present or past conditions like high blood pressure, diabetes, abnormal heart valves, diseased heart muscle, irregular heartbeats, heart defects, serious lung disease, poisons or substance abuse, and sleep apnea (Heart Failure Overview).
Congestive Heart Failure, also known as "cardiac decompensation, cardiac insufficiency, and cardiac incompetence," (Basic Nursing 1111) is an imbalance in pump function in which the heart is failing and unable to do its work pumping enough blood to meet the needs of the body's other organs. To some people, heart failure is defined as a sudden and complete stoppage of heart activityi.e. that the heart just stops beating. This is an inaccuracy. Heart failure usually develops slowly, often over years, as the heart gradually loses its pumping ability and works less efficiently. CHF is a syndrome that affects individuals in different ways and to different degrees. It is usually a chronic disease. It gradually
Congestive heart failure (CHF) is a condition that occurs when the heart is unable to pump blood with enough force to circulate it throughout the body (VanMeter &
Congestive Heart Failure is when the heart's pumping power is weaker than normal. It does not mean the heart has stopped working. The blood moves through the heart and body at a slower rate, and pressure in the heart increases. This means; the heart cannot pump enough oxygen and nutrients to meet the body's needs. The chambers of the heart respond by stretching to hold more blood to pump through the body or by becoming more stiff and thickened. This only keeps the blood moving for a short while. The heart muscle walls weaken and are unable to pump as strongly. This makes the kidneys respond by causing the body to retain fluid and sodium. When the body builds up with fluids, it becomes congested. Many conditions can cause heart
The Canadian Heart and Stroke Foundation defines heart failure (HF) as “a common condition that develops after the heart becomes damaged or weakened by diseases of the heart including heart attacks and other medical conditions. (Heart Failure, 2013)” HF is a chronic medical condition causing the body’s heart to weaken and become unable to pump and supply enough blood and nutrients to the meet the body’s needs. There are four different types of HF: left-side, right-side, systolic and diastolic heart failure (Heart Failure, 2015). Left-side heart failure causes shortness of breath due to fluid backing up in the lungs. Right-side heart failure causes fluid retention in abdomen, legs and feet causing swelling. Systolic heart failure is when the left ventricle can’t contract fast enough, indicating a pumping issue and diastolic heart failure is when the left ventricle can’t relax enough to fill properly, indicating a filling problem (Heart Failure, 2015). These abnormalities in heart function can result a homeostatic imbalance in the kidneys responding by causing the body to retain fluid and salt. The term congestive heart failure (CHF) is used when the heart failure has worsened causing a backup of fluid and congesting extremities and other organs (Heart Failure, 2015). Often, you can control heart failure by taking medicine, changing your lifestyle, and treating the condition that caused it but there is no cure at this time.
Congestive heart failure is an older name for heart failure. Congestive heart failure takes place when the heart is unable to maintain an adequate circulation of blood in the bodily tissues or to pump out the venous blood returned to it by the veins (Merriam-Webster). The heart is split into two distinct pumping structures, the right side of the heart and the left side of the heart. Appropriate cardiac performance involves each ventricle to extract even quantities of blood over intervals. If the volume of blood reimbursed to the heart develops more than both ventricles can manage, the heart can no longer be an efficient pump.
Heart failure is a condition in which the heart muscle becomes too weak to maintain an adequate cardiac output to meet the body’s
Intro- Heart Failure is a multifactorial disease due to significant diminishing of heart pumping action. This is occurs in response to many underlying disease such as diabetes, hypertension, myocardial infarction and cardiac myopathies. These conditons lead to hemodynamic instability, neuroendocrine imbalances and structural remodeling of cardiac myocytes. Early less sever hf allows for compensatory mechanisms such as neuroendocrine stimulation- (beta adrenbergic r endothelin norepinephrine r), and hypertrophy which allow for sufficient left ventricular pumping action. However as hf develops these mechanisms become unable to compensate for the progressive underlying disease which results in further loss of contraction and relaxation efficiency and loss of regulation.
Heart failure (HF) is a pathophysiologic disorder that can result from any structural or functional cardiac disorder that impairs the ability of the ventricle to fill with or eject blood. The most common causes of HF symptoms are coronary artery disease (CAD) and hypertension. Other risk factors include age, obesity, diabetes, renal failure, valvular heart disease, cardiomyopathies, myocarditis, congenital heart disease, and excessive alcohol use. In addition, genetic polymorphisms have been associated to an increased risk for HF, including genes for cardiomyopathies, myocyte contractility, and neurohumoral
