Fundamentally, the heart works as a pump for blood to the various parts of the human body. It is made up of four chambers with two sections, upper and lower, on each side. The heart’s right side pumps blood to the lungs to be oxygenated then the blood returns to the heart’s left side for pumping into the body’s circulatory system that consists of blood vessels that transport the blood through all body organs. Heart failure does not necessarily translate to the complete non-performance of the heart. That is, the heart does not entirely stop its function of pumping blood. Rather, heart failure means that the heart is unable to pump adequately, sufficient oxygenated blood to the body’s tissues (www.emedicinehealth.com, 2015). This inability to adequately pump blood may occur when the muscles of the heart weaken or when there occurs a problem in the heart that inhibits blood from getting into the body’s circulation system (American Heart Association, 2011). When these heart defects hamper normal blood flow, the kidneys receive insufficient blood. Consequently, they are unable to filter the excess fluid adequately from circulation into the urine. The excess fluid in the circulation system collects in some of the organs including the liver, lungs, legs, and eyes (American Heart Association, 2011). The body organs experience a congestion of fluid. Accordingly, this heart condition is commonly referred to as congestive heart failure. Congestive heart failure occurs as a result
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).
The prevalence of congestive heart failure is on the increase both in the United States and all over the world, and it is the leading cause of hospitalization in the elderly population. Congestive heart failure is a progressive disease generally seen in the elderly, which if not properly managed, can lead to repeated hospital admissions or death. Heart failure means that the heart muscle is weakened. A weakened heart muscle may not be strong enough to pump an adequate amount of blood out of its chambers. To compensate for its diminished pumping capacity, the heart may enlarge. Commonly, the heart's pumping inefficiency causes a buildup of blood in the
Heart failure can be attributed to either right sided, left or both. Left-sided heart failure is of two types, systolic failure and diastolic failure. Systolic failure is the when the left ventricle loses its ability to contract normally. The heart cannot pump with enough force to push enough blood into circulation. Diastolic failure is when the left ventricle loses its ability to relax normally. Which results in the heart not being able to fill with blood during the resting period. Both result in a decrease in cardiac output. (AHA, 2012). A decrease in the cardiac output into the systemic circulation causes blood to accumulate in the left ventricle, left atrium, and pulmonary circulation. This increase
After a period of time, the heart muscles of the left ventricle begin to weaken. The weakening of the left ventricle will lead to decreased empting of the heart (systolic heart failure) which results in decreased cardiac output again. Since the left ventricle does not empty completely, blood begins to back up into the left atrium and then to the pulmonary circulation thus resulting in pulmonary congestion and dyspnea (Story 2012, 104). If left untreated, the blood will back up and affect the right side of the heart causing biventricular heart failure (both right and left heart failure). In right sided heart failure, the right ventricle weakens and cannot empty completely. This incomplete emptying causes blood to back up into the systemic circulation causing systemic edema (Lewis et al. 2014, 771).
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,
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
The heart is an organ that pumps oxygenated blood to the body and deoxygenated blood to the lungs. Heart failure is when the heart can’t pump blood very well. If the heart fails to work properly, a major system called the circulatory system won’t work properly and therefore the whole human body will fail to work properly because the cells won’t be able get oxygenated blood and use the oxygen to undergo cellular respiration and make energy.
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
Heart failure, HF, is a result of one’s heart inefficiently pumping blood out to the body (Lewis, Dirksen, Heitkemper and Bucher, 2014, p.766). A healthy heart will pump blood out of the left and right ventricles rhythmically and simultaneously, creating an even flow of blood from the heart to the pulmonary arteries and the aorta (Lewis et al., 2014, p.769). Someone with heart failure has a ventricular dysfunction in either one or both ventricles; the ventricles are not filling or contracting properly. The failure of one ventricle to properly function leads to an overcompensation of the opposite ventricle as well as a disruption in normal blood flow that leads
The body needs a certain amount of cardiac output to maintain its basic functions. In congestive heart failure the body needs more output than the heart can put out. To make up for the lack of cardiac output, the heart sends all of its output to the essential organs such as the brain and lungs. It neglects to send as much blood to the extremities. This is why in congestive heart failure patents, edema is usually present. Fatigue results from the heart having to work extra hard to send blood to only a few essential organs. This is why fatigue is considered the first symptom of congestive heart failure. Congestive Heart Disease can happen on either side of the heart, or it can effect both sides. When the heart cannot keep up with what the body needs capillary pressure increases. When this capillary pressure increases it causes sodium to build up, and the body does not excrete the
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
In right sided heart failure, fluid builds up in the veins and tissues, causing swelling of the lower extremities and the abdomen. When body tissues fail to get the oxygen and the nutrients they require, they begin to lose their efficiency, causing increased dizziness and fatigue.
Heart failure describes the heart’s inability to function properly, meaning the heart is unable to pump efficiently throughout the body. Thus causing the heart to work extra hard in order to compensate the body’s needs, but this ultimately leads to failure. And due to Mrs. Harris’s hypertension and alcohol consumption, she is now displaying signs and symptoms of congestive heart failure, as both are major risk factors. Heart failure can be seen in the left side, which is also known as congestive heart failure, and the right side of heart. The left side is typically the first side to fail, as the left ventricle is the heart’s largest chamber and the most powerful.
In our world organisms occupy a sliding scale of complexity. On one hand we have the single cell organisms, where all necessary functions for their life are carried out within that one cell. At the other extreme we have extremely complex multicellular organisms, of which humans are perhaps the cardinal member. Obviously, with increased capacity comes increased abilities. Complex organisms are able to manipulate their environment to a greater extent then their simpler cousins. While this has a lot of advantages, it also presents interesting biological problems. With the increased complexity multicellular organisms must have systems to deliver nutrients, signaling molecules, and biochemical building blocks to every cell. In
