Papers On Congestive Heart Failure

Symptoms of congestive heart failure consist of fatigue, dependent edema, fluid build-up in the lungs, increase in urination because of the extra fluid, nausea, vomiting, abdominal pain, and decreased appetite (Fundukian, 2011).  Diagnosis of CHF is done first by physical examination, such as heart rate, and heart sounds or murmurs. If a physician believes more tests are needed, common ones include an electrocardiogram or chest x-ray to detect previous heart attacks, arrhythmia, or heart enlargement, and echocardiogram using ultrasound to image the heart muscle, valves, and blood flow patterns. The physician may also want to do a heart catheterization, to allow the arteries of the heart to be visualized using angiography. Upon getting a diagnosis of CHF, the physician will usually start with asking the patient to change things in their diet, such going to a low sodium diet. They may also want to prescribe medications. Types of medications could include angiotensin converting enzyme (ACE) inhibitors, which block formation of angiotensin II hormone, angiotensin receptor blockers (ARB) to block the action of angiotensin II at the receptor site, and diuretics, just to name a few (Fundukian, 2011).

Nearly 5.1 million people in the United States have been diagnosed with heart failure. Yet so many people don’t have a clue what it is until they have been diagnosed with it. Congestive Heart Failure, or CHF, is a disease that has many symptoms, can be tested and treated, has several causes, and can be avoided.

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

To understand the signs and symptoms of left-sided versus right-sided heart failure, remember that left-sided signs and symptoms are found in the lungs. Left begins with L, as does lung. Any signs and symptoms not related to the lungs are caused by right-sided failure (Williams and Hopper). Some signs and symptoms of heart failure are shortness of breath (dyspnea), fatigue, chronic cough or wheezing, rapid or irregular heartbeat, lack of appetite or nausea, mental confusion or impaired thinking, fluid buildup and swelling, and rapid weight gain, and the need to urinate more at night. In order to determine heart failure the physician will do a diagnostic test which includes a chest x-ray, echocardiogram, ejection fraction (EF), and electrocardiogram (EKG or ECG).

Left-sided heart failure occurs when there is damage to the left ventricle. The damage may be due to, for example: high blood pressure, drug abuse, heart attack,

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.

There are several possible risk factors that increase your chance in getting left sided heart failure. Things such as anemia, overactive thyroid, underactive thyroid, and emphysema, leading a sedentary lifestyle, and malnutrition or eating a high-fat diet all are possible contributing factors (Heart Failure, 2014).

Cardiovascular function results from the interplay of the heart, systemic vasculature, blood volume, and tissues in their functions as pump, transporting pathways, and oxygen carrying and consuming end-organs, and problems with structure or function of the filling and ejection mechanisms of the heart will lead to failing oxygen delivery and compensatory attempts, a complex disease condition known as heart failure (Porth, 2015). Dysfunction may involve initially primarily one ventricle only, though over time both sides may become affected. In left ventricular failure decreased cardiac output and outflow into the periphery leads to pulmonary congestion, evidenced by pulmonary edema and impaired gas exchange (Porth, 2015). As a result,

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.

Our heart is a single organ, it acts as a double pump. Without our heart we wouldn’t be living, we need our heart every day, every hour, every minute and every second. The heart pump blood through out our body. The heart has four chambered muscular pumps. The heart weighs approximately 9 ounces. And, has consists of three linings layers. The side of the heart that is affected by congestive heart failure would be both, because the left side (left ventricular) supplies most of the heart pumping power so its-larger than other chambers. And the right side (right ventricular) the heart failure usually loose pumping power, blood backs up in the body’s veins. The fluid accumulate somewhere would go to deliver oxygen rich blood to the body. Diseases

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

It because the heart has weak or damaged ventricular walls that are not able to push enough blood into the body (Congestive Heart Failure Symptoms). Or perhaps it is because the ventricular walls are stiff therefore, the heart does not fill with enough blood. If a person has a left sided heart failure the left ventricle doesn’t deliver enough oxygenated blood full of rich nutrients to the body which causes the person to feel tired and out of breath. The left ventricle also increases the blood pressure in the blood vessels between the lungs and the left ventricle. This increases pressure and forces fluid out of your blood and into your lung tissues, which makes it difficult to breathe. If someone has right-sided heart failure he is unable to contract with enough force to send the blood to the lungs in consequence blood builds up in the veins, throughout the tissues in the body which is called edema. Over time the heart failure on either side of the heart results in weakened and enlarged ventricles resulting in less blood pumping to the body. To make up for the decreased amount of blood the nervous system sends out stress hormones that increase the speed and force of the heartbeat. Unfortunately, the continued release of these hormones makes the heart failure worse because they damage the muscle cells in the ventricles (Moore). The common cause of heart failure is

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).

When the left heart failure, pulmonary blood flow to stagnant. This can lead to fatigue, shortness of breath (especially the evening while lying down), and cough.

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).
