Heart failure is a chronic and progressive disease where the heart muscles fail to properly pump the necessary amount of blood through the body (American Heart Association). According the Center of Disease and Control (CDC), 5.7 million adults are suffering from heart failure and 1:9 cases result in death. Though, heart failure is general term and encompasses three types of heart failure. The different types of heart failure are left-sided heart failure, right-side heart failure, and congestive heart failure and each has distinctive features that define them. Left side heart failure is described as the heart’s failure to pump blood to the body. Right side heart failure occurs when there is an increased build up in fluid as blood is being returned
The aim of this report is to provide an overview of chronic heart failure, examining signs symptoms and treatment related to the case study, and the anatomy and physiology of the heart will be discussed, and the pathophysiology of chronic heart failure.
It occurs because of repetitive electrical activity. This can occur in a patient with early or late heart failure, because there is damage to the heart tissue and the heart beats faster to try to supply the body with blood. Recommended treatment is elective cardioversion. Drugs used include an antidysrhythmic such as Mexitil or Sotalol (Ignatavicius &Workman, p. 728-729).
Cardiomyopathy, by definition, means the weakening of the heart muscle. The heart is operated by a striated muscle that relies on the autonomic nervous system to function. Cardiomyopathy is diagnosed in four different ways based on what caused the illness and exactly what part of the heart is weakened. The four main types of cardiomyopathy are dilated cardiomyopathy, hypertrophic cardiomyopathy, restrictive cardiomyopathy, and arrhythmogenic right ventricular dysplasia. One other category of cardiomyopathy that is diagnosed is “unclassified cardiomyopathy.” Unclassified cardiomyopathy is the weakening of the heart that does not fit into the main four categories.
This systematic review conducted by Takeda A, Taylor SJC, Taylor RS, Khan F, Krum H, Underwood M, (2012) sourced twenty-five trials, and the overall number of people of the collective trials included was 5,942. Interventions were classified and assessed using the following headings.-
These causes will change the heart significantly. The pathophysiology of heart failure is described differently as: (1) an oedematous disorder, by means of which the deviations in renal hemodynamics and excretory ability lead to salt and water holding; (2) a hemodynamic disorder, considered by peripheral vasoconstriction and decreased cardiac output; (3) a neurohormonal disorder, mainly by stimulation of the renin-angiotensin-aldosterone system and adrenergic nervous system; (4) an inflammatory syndrome, related with amplified local and circulation pro-inflammatory cytokines; (5) a myocardial disease, started with an damage to the heart trailed by pathological ventricular transformation. In heart failure, the heart sustains either a sudden or longstanding structural injury. When damage occurs, sequences of firstly compensatory but consequently maladaptive mechanisms follow (Henry & Abraham, ).
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 failure, and they are Coronary artery disease, Heart attack, Cardiomyopathy, and conditions that overwork the heart.
Heart failure is a major clinical, social and economic problem in the United Kingdom according to the Department of Health [DH] (2013).The National Institute for Health and Clinical Excellence [NICE] (2010) reported that about 900,000 people suffer from heart failure in the United Kingdom. The National Institute for Cardiovascular Outcomes Research [NICOR] (2011) conducted a national audit which found that one in every 20 people over the age of 65 is diagnosed with heart failure which demonstrates that it mainly affects the elderly. As a leading cause of mortality, heart failure contributes to more than 6,000 deaths each year (NICOR, 2011). Newly diagnosed cases of heart failure have a 40% risk of dying within a year (NICOR, 2011). Despite advances in therapy, mortality is still high and only half of patients are alive five years after being diagnosed with heart failure (NICE, 2010).
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 pathophysiology of left-sided heart failure is primary a macroscopic disorder and will be described as such.
“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” (American Heart Association, 2012, para 3). What this basically means is that the body is functioning in a way that the heart cannot keep up with. Although heart failure can be acute and occur suddenly, it usually develops over time and is a long-term or chronic condition. There are two different types of heart failure, left-sided and right-sided, and they can be caused by other diseases such as diabetes, coronary heart disease, or high blood pressure (National Institutes of Health, 2012). In most cases, both sides of the heart are affected simultaneously.
Congestive heart failure represents the end product of the many conditions that reduce the thrusting ability of the heart. Congestive heart failure is not a detailed disease but a illness that is measured by the inability of the heart to pump blood adequate with the metabolic needs of the body. Heart failure is accompanied by overcrowding of the body tissues. For instance, heart failure may be shown as an acute condition as in pulmonary edema or as a chronic condition as in congestive heart
Heart disease can take many forms. The form of heart disease I am focusing on is coronary disease. Different arteries supply different areas of the heart with oxygenated blood. If one or more of these arteries become narrowed or clogged as a result of coronary artery disease, or atherscelorosis the artery cannot fully supply the part of the heart it is responsible for. The heart is an effective pump only when good blood supply is maintained to all heart muscles.
Heart disease is the leading cause of death worldwide. (social inequality, 2009). Heart disease is a structural or functional abnormality of the heart, or the blood vessel supplying the heart, that impairs its functioning. (free dictionary). Heart disease is also known as cardiovascular disease. Since there are many conditions related with heart disease. The most common types are coronary artery disease or damage in the heart’s major blood vessels, stroke or damage to the brain from interruption of its blood supply, and high blood pressure or a condition in which the force of the blood against the artery walls in too high. These conditions may lead to a heart attack. (mayo).

Congested Heart Failure is a chronic condition that affects pumping power of the heart muscle. Sometimes it is just referred to “heart failure”, sometimes people without specifying can understand different. Congested heart Failure specify talks about where the fluids build up around the heart causing it to pump inefficiently. In the heart we have four chambers in which the ventricle is the one that pumps blood to the organs. Congested Heart Failure also known as CHF starts to develop when the ventricles cannot pump enough blood to the whole body. As that starts to happen the blood starts to back up inside the lungs, liver, abdomen, and lower body. As everyone knows CHF can be life threatening.
Heart is a muscle that pumps blood to every organ to maintain oxygen and nutrients to provide body to energy in order to keep health body. It's about the size of your fist, which is located in the left of center in our chest. If it does not work properly, it causes what is known heart failure, a disease that occurs when heart does pump blood adequately to meet body’s need. Heart failure is divided two main parts, right sided heart failure and left sided heart failure. Patient with right sided heart failure experience symptoms such as swelling in the feet
