Diastolic Heart Failure And Congestive Failure

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

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).

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.

Left-sided heart failure is the most common type of heart failure, and it is a result of left-ventricular dysfunction. This disease poses a significant threat to patients because the primary function of the left side of the heart is to provide sufficient oxygenated blood to satisfy the metabolic demands of the body’s cells. Understanding the main function of this portion of the heart will help with the understanding of other complications associated with this diseased. Left-sided heart failure is usually the result of the loss of heart muscle function, specifically in the left ventricle secondary to coronary artery disease, prolonged hypertension, or myocardial infection (Lewis et al. 2014, 766). The

In systolic ventricular dysfunction or systolic heart failure the heart is not able to produce enough output for adequate tissue perfusion. Heart rate and stroke volume produce cardiac output. Contractility, preload, and afterload influence the heart’s stroke volume. These factors are important in understanding the pathophysiologic consequences of this syndrome and possible treatments. Patients with systolic heart failure usually have dilated, large ventricles and impaired systolic function.

Congestive Heart Failure affects men and women equally, however African Americans are 1.5 times more likely to have Congestive Heart Failure than Caucasians ("Heart failure statistics," 2015). Congestive Heart Failure can affect people of any age; 1.4 million diagnosed Congestive Heart Failure patients are under 60 years old, 2% of Congestive Heart Failure diagnosed patients are between 40 to 59, and over 5% of people between 60 to 69 years old are diagnosed with Congestive Heart Failure ("Heart failure statistics," 2015).Over half of the Congestive Heart Failure diagnosed patients die within 5 years of being diagnosed ("Heart failure statistics,"

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 activity—i.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

There are many causes for heart failure. The most common cause is coronary heart disease (Moore and Roth, 2015). CHD is a disease in which the coronary arteries are blocked, preventing the heart muscles from getting the oxygenated blood they need. Heart failure can be caused by other present or past conditions like high blood pressure, diabetes, abnormal heart valves, diseased heart muscle, irregular heartbeats, heart defects, serious lung disease, poisons or substance abuse, and sleep apnea (Heart Failure Overview).

Congestive heart hailure, also known as CHF or heart failure, affects the lives of 5 million Americans each year with 550,000 new cases diagnosed yearly. (Emory healthcare, 2013) CHF is a medical condition in which the heart has become weak and cannot pump enough blood to meet the need for oxygen rich blood required by the vital organs of the body, less blood is pumped out of the heart to the organs and tissues in the body and pressure in the heart increases, it does not mean the heart has stopped working. (Murphy, 2013) Once the heart has become weakened by conditions such as hypertension, abnormal heart

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

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

Diastolic dysfunction is a problem with the ventricle’s ability to relax and fill. Mixed systolic and diastolic dysfunction is a combination of the two defects (Williams and Hopper).

I. Description: Congestive Heart Failure is more of a syndrome than a disease. Heart failure may be classified according to the side of the heart affected, (left- or right-sided failure), or by the cardiac cycle involved, (systolic or diastolic dysfunction). (Schilling-McCann p. 176). The word "failure" refers to the heart's inability to pump enough blood to meet the body's metabolic needs. (Schilling-McCann p. 176). When the heart fails to deliver adequate blood supply edema may develop. (Cadwallader p. 1141). Where edema occurs depends on what side of the heart is failing.

Diastolic dysfunction is the result of several diseases such as, diabetes mellitus, hypertension, obesity, and chronic kidney disease, which provoke a systemic inflammatory state with high circulating levels of glycoprotein and tumor necrosis factor. This inflammatory state leads to coronary micro vascular endothelial dysfunction with reduced vasodilator response to acetylcholine as a result of low nitric oxide availability and increase in reactive oxygen species production. Diastolic dysfunction will also be the result of an abnormal active process of relaxation linked to an abnormal calcium handling mechanism. This increase in stiffness and decrease in arterial compliance lead to an abnormal vasodilator response to exercise, which causes

Congestive heart failure is a chronic disease that requires daily monitoring and life style management. Affecting the elderly, and their family the adjustment is a challenge. Daily life skills include the monitoring of daily weights, intake and output, and a low sodium diet. The person with congestive heart failure is generally admitted to the hospital for medication adjustments when their symptoms increase. The patient is often times short of breath, with a decrease in energy and an increase in their weight. The patients are generally elderly 60-65 years of age or older, and when comparing African Americans to Caucasians the African Americans have a 1.5 greater chance of developing heart failure ("Heart Failure," 2017).
