The pathophysiology of congestive heart failure is a viscous cycle. It starts out by some form of heart destruction or weakening of the heart muscle, usually caused by clogged arteries due to coronary artery disease or increased pressure on the left ventricular wall from chronic long term hypertension. This dwindling of the heart decreases stroke volume. The Medical Dictionary for Health Professionals and Nurses (2012) defines stroke volume as the volume pumped out of one ventricle of the heart in a single beat. So when stroke volume goes down, cardiac output also goes down. Medicinenet.com (2016) defines cardiac output as the amount of blood the heart pumps through the circulatory system in a minute, they describe that a normal adult has a cardiac output of 4.7 liters (5 quarts) …show more content…
The Mayo Clinic (2014) gives the definition of dilated cardiomyopathy as a disease of the heart muscle, usually starting in your heart 's main pumping chamber (left ventricle). They go on to explain that dilated cardiomyopathy might not cause symptoms, but for some people it can be life-threatening causing irregular heartbeats, blood clots or sudden death. Another thing that is seen in the heart muscle during congestive heart failure is that the walls of the ventricles are thickening. This is called hypertrophic cardiomyopathy. The American Heart Association (2016) explains that hypertrophic cardiomyopathy occurs if heart muscle cells enlarge and cause the walls of the ventricles (usually the left ventricle) to thicken. The ventricle size often remains normal, but the thickening may block blood flow out of the ventricle. In this situation the walls are getting thicker trying to pump more blood, but they are getting stiffer as well and there is less room for blood. Although the ventricle is trying to pump more blood, it is not being successful, which causes a progressive drop in stroke volume. Again, stroke volume is the amount of blood pumped out of the heart with each beat to the
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.
Hypertrophic Cardiomyopathy, also known as HCM, is a type of heart disease that affects the Cardiac Muscles and Cardiac Muscle cells. This disease occurs if the Cardiac Muscle cells enlarge, which causes the wall of the heart’s ventricles (most often the left ventricle) to thicken. It can also cause stiffness in the ventricles, as well as mitral valve and cellular changes.
The thickening of the muscle cells do not necessarily have to change the size of the ventricles, but can narrow the blood vessels inside the heart. Hypertrophic cardiomyopathy can be grouped into two categories: obstructive HCM and non-obstructive HCM. With obstructive HCM, the septum (the wall that divides the left and right sides of the heart) becomes thickened and blocks the blood flow out of the left ventricle. Overall, HCM usually starts in the left ventricle. HCM can also cause blood to leak backward through the mitral valve causing even more problems. The walls of the ventricles can also become stiff since it cannot hold a normal amount of blood. This stiffening causes the ventricle to not relax and entirely fill with
Heart disease is the leading cause of death in the United States and the estimated cost of treatment is $32 billion yearly. Approximately 5 million people living in the United States suffer from congestive heart failure (CHF) and half of those diagnosed will die within 5 years. An individual may present to the hospital with weakness, short of breath (SOB), swelling of the extremities, ascites, and breathing difficulties while lying down. The quality and length of life for someone suffering from heart failure can be improved with early diagnosis, medication, physical activity, and diet modification (CDC, 2013).
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, ).
The human body is an amazing machine, we have cells, tissues, organs and organ system that come together to create the human race. Each system plays a key role in our bodies mechanism. Without each systems our bodies would not function properly, but what happens when one of these system fails? The Cardiovascular system components are blood, blood vessels and the heart. The hearts function is to pump blood to all the major organs and tissues (Circulatory). It’s also important to be aware of the derivation that our bodies may encounter, for example a stroke. In this passage I discuss different types of strokes, what are the signs and symptoms and after care for this disorder of the cardiovascular system.
As cardiomyopathy worsens, the heart becomes weaker. It 's less able to pump blood through the body and maintain a normal electrical rhythm. This can lead to heart failure and rhythm problems. In turn, heart failure can cause fluid to build up in the lungs, ankles, feet, legs or abdomen.
Patients with dilated cardiomyopathy will often have normal thickness of the ventricles with an enlarged right, left, or both ventricular cavities. In the early stages of this disease, there is an initial increase in the stroke volume from the increased force of contraction due to the stretching of the myocardium, which is described by the Frank-Starling mechanism. However, as the disease progresses, the heart loses that compensatory mechanism leading to a decrease in the strength of the contraction of the heart, hence, a decrease in left ventricular ejection fraction. There are two types of DCM, primary and secondary. Primary dilated cardiomyopathy are usually idiopathic in nature, however, “approximately 30% of cases” have a “familial transmission pattern.”3(138) Secondary dilated cardiomyopathy, on the other hand, are associated with “alcohol abuse, cocaine abuse, the peripartum state, pheochromocytoma, infectious diseases (human immunodeficiency virus infection), uncontrolled tachycardia, Duchenne’s muscul...
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.
The best way to prevent heart failure is to minimize the risks that cause it and to control existing health problems that are related to the condition such as high blood pressure and diabetes. If a person does happen to have heart failure there are many medications and treatments that can help control the disease and help the patient continue to live as normal of a life as possible. After being discharged from the hospital Mr. Carver will have to be aware of his condition at all times and take the proper measures to keep himself healthy. He will have to make many life changes and continue to keep up on any appointments made to make sure his condition is under control. With the proper understanding and management of his disease, Mr. Carver will be in a good condition to resume his life as before.
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 increase in size. As a result, the cardiac muscles become abnormally thick, making it difficult for the cells to contract and the heart to pump. A genetic mutation causes the myocytes to form chaotic intersecting bundles. A pathognomonic abnormality called myocardial fiber disarray. [2,12] How the hypertrophy is distributed throughout the heart is varied. Though, in most cases, the left ventricle is always affected. [3] The heart muscle can thicken in four different patterns. The most common being asymmetrical septal hypertrophy without obstruction. Here the intraventricular septum becomes thick, but the mitral valve is not affected. Asymmetrical septal hypertrophy with obstruction causes the mitral valve to touch the septal wall during contraction. (Left ventricle outflow tract obstruction.) The obstruction of the mitral valve allows for blood to slowly flow from the left ventricle back into the left atrium (Mitral regurgitation). Symmetrical hypertrophy is the thickening of the entire left ven...

Dilated cardiomyopathy accounts for approximately 15% of heart failure cases in the under 75s (“Chronic Heart Failure”). Patients with Dilated cardiomyopathy are usually unaware of the disease until they experience the signs and symptoms of heart failure or they develop an arrhythmia.
The aim of this scenario-based assignment is to discuss the therapeutic intervention in the care of a patient with Congestive Cardiac Failure (CCF). A brief summary of the patient’s medical history will be given while discussing one specific nursing problem in terms of heart rate/ rhythm. Also, an overview of aetiology will be given as well as pathophysiology in order to explain the rationale for treatment and monitoring. Relevant research relating to the literature will be utilised throughout in order to critically analyse the care provided for the patient and determine if the patient received evidence based up-to-date care. In accordance with the statement from the Nursing and Midwifery Council (2008) code of conduct regarding patient confidentiality, no personal details of the patient involved will be disclosed. Therefore, the patient will be identified as Mrs S.
