Asha Thompson Ms. Kimbrough Medical: Cardiomegaly 2 June, 2015
Cardiomegaly is a descriptive term used for the finding of an enlarged heart and is not a disease itself. Cardiomegaly is a disorder and condition which the heart has enlarged to the point that it is 50 percent larger than the diameter of the surrounding rib cage. It can sometimes be nonpermanent due to stress on the body, for example like pregnancy, obesity, other medical conditions etc., due to statistics the number of people diagnosed with heart diseases is 11.3%. The amount
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.
Ebstein’s Anomaly is a rare congenital condition, present at birth, in which the tricuspid valve is malformed and the valve itself is not in the correct anatomic place (Mayo Clinic Staff). This anomaly affects the right side of the heart – the tricuspid valve is located too deep into the ventricle, causing a smaller and weaker right ventricle. The space above the decreased right ventricle is made up of atrial tissue and this can be referred to as right ventricle dysplasia or an atrialized right ventricle (Reynolds). Typically the tricuspid valve has three freely moving leaflets, but in Ebstein’s anomaly one or two of those leaflets get fused to the heart walls causing regurgitation. Since the heart does not work as efficiently in those who have this anomaly, the heart usually compensates and becomes enlarged. It...
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.
In case of chronic stage, treatment of cardiomyopathy is mainly symptomatic and similar to the treatment of the other causes of heart disease. There may be a need for a pacemaker and a heart transplant can be considered.
Hypertrophic cardiomyopathy is a genetic disease of the heart, making the cardiac muscle is thick and strong. The thick muscle causes a decrease in cavity size, forcing the heart to pump less blood. Hypertrophic cardiomyopathy is one of the primary causes of sudden death as the prevention of blood flow causes cardiac arrest. More successful research is being conducted on HCM, including research on the genetics associated and the heredity of the genes. Unfortunately this disorder effects many young athletes due to their increased stresses of training on their heart. However, despite the use of new technology such as the electrocardiogram and transthoracic echocardiogram, the strategies are limited, restricting new answers.
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...
“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.
Heart disease describes a range of conditions that affect your heart. Diseases under the heart disease umbrella include blood vessel diseases, heart rhythm problems, and heart defects. The major cause of this is a build-up of fatty plaques in the arteries. Plaque build-up thickens and stiffens the vessel walls, which can inhibit blood flow through the arteries to organs and tissues.
Symptoms to heart disease can include chest pain, shortness of breath, pain, numbness, weakness or coldness in your legs or arms, if the blood vessels in those areas are narrow. There are many causes of heart disease. You can just be born with heart defects, or naturally cause them yourself by smoking, excessive use of alcohol, also having high blood pressure, diabetes. Abusing drugs can also cause heart disease too. Stress is a cause of heart disease. Even over the counter medications can cause a heart problem. There is a good amount of test that is used to diagnose heart disease. Blood test, chest x-rays, tilt table test which is use to help find fainting spells, stress test which evolves an evaluation of the hearts response during moderate exercise while a 12-lead ECG is performed, electrocardiograms, heart MRI, holter monitoring is where the heart is recorded while the patient is ambulatory for at least a 24-hour period, echocardiogram, cardiac catheterization, heart biopsy which is where the doctor removes a part of the heart tissue, cardiac computerized tomography (CT) scan helps to visualize the hearts anatomy, and cardiac magnetic resonance imaging are all test that is use to see if someone has a form of heart disease. There are treatments to help prevent heart disease. Depending on how bad the form ...
What is coronary heart disease (CHD)? It is a disease when plaque gets built up in the coronary arteries; and the job of the arteries are to provide rich-oxygenated blood to the heart muscle. Built plaque in the arteries leads to atherosclerosis and the plaque that is built can result from over the years. Throughout the years, the plaque tends to get hard or can rupture. If hardened, the arteries are now narrow and have weakened the flow of blood that travels to the heart. Blood clots can form from the plaque rupturing which can cause a great chance for the blood flow to be mostly blocked or blocked altogether. There are other names for coronary heart disease such as coronary artery disease, atherosclerosis, ischemic heart disease, etc.
(Slide 2) What is Cardiomyopathy? If we break down the word we can see “Cardio” which means of the heart, “myo” which means muscle, and “pathy” which means disease, therefore cardiomyopathies are diseases of the heart muscle. (Slide 3) There are 3 main types of cardiomyopathies; hypertrophic, dilated, and restrictive. I will only be discussing dilated cardiomyopathy, which is characterized by the enlargement of the hearts chambers with impaired systolic function. It is estimated that as many as 1 of 500 adults may have this condition. Dilated cardiomyopathy is more common in blacks than in whites and in males than in females. It is the most common form of cardiomyopathy in children and it can occur at any age (CDC).
When the era has changed, people had turned to pay attention to more exercises, including cardio exercise in order to be able to protect themselves from the negative effect of this changing. For example, playing cardio helps people to make the body strong due to the weather that has the dust. The fact is from my experience and observation found that most people tend to neglect to take care of health. It appeared that poor health, so causes vision to develop this issue. What’s worse, when people want to investigate exercise to achieve the best for them; how they will know what kind of exercise is best. And what is the definition of workout that people who exercise tend to play regularly. The exertion and the movement of the body make the body
Nutrition is a major importance in the prevention of diseases and also an important maintenance for pets with chronic disorders (congestive heart failure, renal disease, etc.). Certain prescription diets have been designed with the intent to either cure or prolong the patients’ well-being. The affects that malnutrition have on the cardiovascular system range from muscle loss/weakness, anemia from vitamin/mineral deficiencies, and loss of myocardial muscle from decreased protein intake (Webb et al., 1986). Certain vitamins and minerals such as iron, copper, folic acid, and B12 deficiencies will cause anemia. The loss of the blood to the cardiovascular system decreases the amount of oxygen delivered to the tissue, which causes elevation in the heart rate (tachycardia), because the heart is trying to compensate for the lack of
Joslyn P. Gipson Professor Name Hay Richard Class: English 12/21/2023 The-Tell-Tale-Heart Thesis Statement: The narrator’s unknown disease drives him further into madness. In the first paragraph, the narrator talks about how his disease has enhanced his senses, and claims he hears things no one else can. “ The disease had sharpened my senses – not dulled them. Above all was the sense of acute hearing.
Heart disease can refer to an assortment of diseases affecting the heart. A heart attack happens when a heart muscle is destroyed or hurt due to not getting enough oxygenated blood to maintain life. Different examples of Heart Disease include Cardiomyopathy, Cardiovascular Disease, Hypertension, and Ischemic Heart Disease.
