Left-Sided Heart Failure Research Paper

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

Hypertrophic cardiomyopathy is an inherited disease that affects the cardiac muscle of the heart, causing the walls of the heart to thicken and become stiff. [1] On a cellular level, the sarcomere

Systolic heart failure is characterized by enlarged ventricles that are unable to fully contract to pump enough blood into circulation to adequately perfuse tissues. The enlargement in ventricles is due to an increased end-systolic volume. If the heart is not able to sufficiently pump the expected volume of blood with each contraction, which in a normal healthy heart is 50-60%, there will be a residual volume left in the heart after every pump (Heart Healthy Women, 2012). With the next period of filling, the heart will receive the same amount of blood volume from the atria combined with that residual volume from the previous contraction. This causes the ventricles to have to dilate to accommodate this increase in volume. The dilation causes the walls of the ventricles to stretch and become thin and weak. Also the myocardium, the muscle layer of the heart, will stretch and not be able to adequately make a full and forceful enough contraction to push blood from the ventricles (Lehne, 2010).

Both the right and left atrium contract causing blood to flow though the two valves, and then into the left ventricle. The left ventricle pumps blood into the systemic circulation through the aorta. This systemic circulation system is much bigger than the pulmonary circulation system, which is why the left ventricle is so big. The blood on the left side of the heart is oxygenated. It becomes oxygenated when the deoxygenated blood passes through the right atrium and then flows into the left ventricle. It is then pumped along the pulmonary artery into the lungs where it is oxygenated. It then travels through the pulmonary veins back into the heart. It enters through the left atrium and then travels to the left ventricle. This process is repeated over and over again, to make blood continuously flow through the heart, lungs and body. This process ensures that there is always enough oxygen for the body to work

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

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).

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

There is no cure or recovery from congestive heart failure, but there are ways to improve your hears condition.

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,

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

The major causes of diastolic heart failure are hypertension-induced myocardial hypertrophy and myocardial ischemia-induced ventricular transformation (coronary artery disease). Hypertrophy and ischemia cause a decreased ability of the myocytes to actively pump calcium from the cytosol, resulting in impaired relaxation. Some of the other causes are aortic valvular disease and cardiomyopathies. Diabetes can also lead to diastolic heart failure (Huether and McCune 2012). Other risk factors for this disease are chronic kidney disease, obstructive sleep apnea, and older age. There are two types of the heart failure: systolic heart failure and diastolic heart failure. In systolic heart failure, the left ventricle has difficulty contracting and ejecting blood into the circulation, which causes reduced left ventricular fraction. On the other hand, diastolic heart failure has a slow and delayed relaxation and increased chamber rigidity, which then causes inadequate filling of blood and
