Heart failure is defined as the heart’s inability to pump as well as it should be able to. When the heart does not pump the appropriate amount of oxygen and nutrients, “the body’s needs cannot be met”. There are two different types of heart failure- systolic heart failure and diastolic heart failure; both use an EF, ejection fraction, to diagnose them. “Systolic dysfunction occurs when the heart muscle does not contract with enough force, so there is less oxygen-rich blood that is pumped throughout the body.” “Diastolic heart failure occurs when the heart contracts normally, but the ventricles do not relax properly or are stiff, allowing less blood to enter the heart during normal filling” (“Congestive Heart,” 2014). Multiple diseases and day to day actions attribute to heart failure such as, cardiomyopathy, heart attack, conditions that put huge amounts of stress on the heart, and coronary disease, commonly known as CAD.Multiple diseases and day to day actions attribute to heart failure such as, cardiomyopathy, heart attack, conditions that put huge amounts of stress on the heart, and coronary disease, commonly known as CAD. …show more content…
Heart attacks are often causes of heart failure. A heart attack occurs when, “a coronary artery becomes blocked suddenly, stopping the flow of blood to the heart muscle.” A heart attack injures the heart muscle, scarring a part of the heart and resulting in a region of the heart unable to function like it typically would. Coronary artery disease is also a cause of heart disease. CAD is a “disease of the arteries that supply blood and oxygen to the heart.” When multiple disease are occurring at once, that can also be a facyor leading to heart
Diastolic function is the ability of the ventricles to relax and fill properly. If the chamber is unable to relax and fill properly than this can cause systolic dysfunction.
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).
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.
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.
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.-
Dilated cardiomyopathy (DCM) is “a syndrome characterized by cardiac enlargement and impaired systolic function of one or both ventricles.”4(1175) Through medical technology and proper medical regimen, people afflicted with this syndrome today, are living longer and are undergoing surgeries that may not be cardiac-related. Therefore, anesthesia providers may encounter increasing amounts of patients with DCM as compared in the past. As anesthesia providers, it is important to have an understanding of the pathophysiology of DCM and its anesthetic implication. This topic will focus on anatomy and physiology of DCM, the effects it has on the anesthetic plan, and a review of current literature.
Systolic and Diastolic are the two types of heart failure. Systolic dysfunction occurs when the heart muscle doesn't contract with enough force, which means there is less oxygen-rich blood that is pumped throughout the body. Diastolic dysfunction is when the heart contracts normally, but the ventricle does not relax properly, reducing the amount of blood that can enter the heart and raising the blood pressure in the lungs. Heart failure is a progressive condition and can worsen over time. There are four stages of heart failure that have been classified by the AHA and ACC.
According to the European Society of Cardiology Guidelines [ESC] (2012) heart failure is diagnosed by symptoms such as dyspnoea, fatigue, either at rest or during exertion.
“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.

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 ...
Just as breast cancer is killing our African American women, heart disease is also one of the major diseases killing our women. Heart disease is one of the nation’s leading causes of death in both woman and men. About 600,000 people die of heart disease in the United States (Americas heart disease burden, 2013). Some facts about heart disease are every year about 935,000 Americans have a heart attack. Of these, 610,000 are a first heart attack victim. 325,000 happen in people who have already had a heart attack. Also coronary heart disease alone costs the United States $108.9 billion each year. This total includes the cost of health care services, medications, and loss of productivity. Deaths of heart disease in the United States back in 2008 killed about 24.5% of African Americans.
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.
...heart attack. Heart Disease can refer to an assortment of diseases affecting the heart. A heart attack happens when 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 Hear Disease.
