Symptoms of heart failure are divided into two parts which are left and right sided of the heart. Heart failure may happen due to the “pooling” of fluid in the lungs, abdominal area, legs or feet; it can also be caused by decreased blood flow to the body. The left-sided failure of the heart causes blood to back up or be congested to the lungs, causing respiratory symptoms such as: shortness of breath all the time especially during the night while sleeping, frequent dry cough and many more. Left side failure also gives fatigue which is due to insufficient supple of oxygenated blood. Whereas, right-sided failure is often caused by pulmonary heart disease, which usually caused by the difficulties of pulmonary circulation. This side of failure
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
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).
The left side of the heart brings oxygen-rich blood from the lungs through the left atrium to the left ventricle, then out into body. When the left side of the heart is damaged or can’t pump as well, it has to work harder to send blood through the body. This causes fluid to build up in the body, especially the lungs. That’s why shortness of breath is one of the most common symptoms of heart failure. Systolic failure happens when the heart doesn’t pump out blood the way it should. Diastolic means the heart doesn’t fill back up with blood as it should. The symptoms of left sided heart failure are tachypnea, increased work of breathing, crackles initially heard in lung bases, but when severe, heard throughout the lung fields, pulmonary edema, and dullness in lung fields to finger percussion, pleural effusion detectable by reduced breath sounds at the bases of the lungs, and cyanosis.
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).
This occurs because when the right heart fails as a forward pump, cardiac output falls, resulting in backward dumping and leading to what is commonly known as "backward failure." If the right ventricle cannot pump effectively, the volume of blood in the veins increases, leading to congestion, similar to that of left-sided failure. Venous congestion in the form of edema is often easy to see in areas of the body lower than that of the heart. The venous congestion is also the cause of swollen ankles that many patients with right-sided heart failure tend to display.
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
With left-sided heart failure a patient can suffer from fluid in the lungs, shortness of breath and pulmonary edema, and fatigue. Since the heart can not pump the adequate amount of blood to the rest of the body, there is a lack of oxygen in the body and this results in fatigue. Left-sided heart failure causes an increase in pressure within the vessels in the lungs, which can lead to an accumulation of fluid within the lungs, which leads to shortness of breath and pulmonary edema. There is a wide variety of causes of left-sided heart failure with include consuming too much alcohol, suffering from a heart attack, infections of the heart muscle, increased blood pressure, hypothyroidism, narrow heart valves, and any disease that can cause damage to the heart muscle. Left-sided heart failure in children is often caused by birth defects including abnormal
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 patient may experience dyspnea, caused by pulmonary congestion. They may report orthopnea as blood is redistributed from the legs to the central circulation when the patient lies down a night, paroxysmal nocturnal dyspnea due to reabsorption of interstitial fluid when lying down, and reduced sympathetic stimulation while sleeping. Pulmonary congestion may also cause a non-productive cough. Later clinical manifestations of left sided heart failure include crackles due to pulmonary congestion and hemoptysis resulting from bleeding veins in the bronchial system caused by venous distention. On physical exam the patient may have cool, pale skin resulting from peripheral vasoconstriction, and may be restless and confused due to reduced cardiac
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
sided heart failure that is forward failure can be manifested by fatigue, oliguria, increased heart rate, faint
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).
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.
