Pathophysiology of Chf

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 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

When CHF starts to become worse, fluid can start to fill up in a person’s lungs and sometimes even throughout a person’s body. The fluid could cause a person to feel out of breath even while resting, swelling in the legs, ankles, or feet, weight gain, feeling bloated, and coughing, wheezing, and having to use the bathroom more at night. There is also a possibility that CHF can happen all of a sudden. When it starts to happen, it is called sudden heart failure. It will eventually cause congestion from fluid building up in the lungs. Symptoms can start to happen by having severe shortness of breath, an irregular or maybe even a fast heart beat and it may even cause coughing up foamy, pink mucus (Heart-Failure

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

Diastolic heart failure or diastolic dysfunction is when the left ventricle does not relax normally. This pushes the heart to pump too quickly, permitting the heart from filling the chamber with enough blood during the resting period betweens beats (Types of Heart Failure). Right-sided heart failure is usually a consequence of left-sided heart failure. When the heart loses its main source of pumping power, the right side of the heart is affected by blood being pushed into the veins of the body causing swelling. These heart conditions can be ongoing or they can start abruptly which can have a huge impact on the body (Types of Heart Failure).

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 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

Left sided heart failure that is forward failure can be manifested by dyspnea on exertion, ortopnea,

Congestive Heart Failure is a condition in which the heart cannot pump enough blood to meet the needs of the rest of the body (Department of Health & Human Services, 2012). The failure can occur in on either side of the heart. In left-side heart failure, fluid backs up into the lungs, causing shortness of breath, due to the fact that the blood entering the left side of the heart comes from the pulmonary artery, and when the left ventricle cannot pump fluid out of the heart or when the left atrium cannot empty completely into the ventricle it backs up into the lungs. In right-side heart failure, fluid can back up into the abdomen, legs, and feet, causing swelling. The blood being pumped into the right

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 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.
