The heart can not pump enough power to push blood in enough circulation. Diastolic insufficiency (diastolic dysfunction, preserved ejection fraction, also called heart failure or HFPEF) occurs when the left ventricle is stiffened so that the heart can not be correctly filled with blood during rest between each beat. Heart failure to the right: left to right (also called right ventricular) heart failure usually occurs due to a left-sided malfunction. When the left ventricle fails, the increased fluid pressure is returned from the lungs to damage the right side of the heart. When the right side loses its pumping power, the blood is backed up in its vascularized veins and causes swelling or blockage in the legs, ankle, gastrointestinal tract and liver.
These conditions harm your heart, making the heart muscle hardened or thick. The harmed muscle either can't unwind appropriately to let the pumping assemblies of the heart, the ventricles, load with enough blood, or it can't contract legitimately to give the ventricles a chance to pump sufficiently out blood. The left ventricle is the primary pumping chamber, and heart failure normally begins on the left side. At the point when the left ventricle can't contract enough, it is called systolic heart failure. At the point when the left ventricle can't load with enough blood, it is called diastolic heart failure.
Congestive heart failure Author: Dr. Simona Stiuriuc Patogenie.Cauze and riscSemne and simptomeDiagnosticTratamentPrognostic factors. Congestive heart failure Congestive heart failure occurs when the heart can no longer cope with the metabolic demands of the body at normal venous pressure. The heart can not respond to increased body cererilee because: - Increased heart rate, which is controlled by neural and humoral - Increased ventricular contractility, secondary circulating catecholamines and autonomic control - Increase preload, mediated constriction of venous capacitance and preservation of renal intravascular volume. As the heart demands exceed normal compensatory mechanisms appear signs of congestive heart failure. These signs include
It accumulates fluid in the lungs, which is called "pulmonary congestion." The body does not get enough blood, nutrients and oxygen. What are the symptoms of heart failure? • Shortness of breath, especially when you lie • Feeling tired, exhaustion • cough or wheezing, especially when the person you exercise or lie • Swelling in the feet, ankles and legs • Weight gain due to retention • Confusion or lack of mental clarity What are the causes? The most common cause of heart failure is coronary artery disease (CAD).
Right ventricular hypertrophy occurs due to the pressure exerted against pulmonary stenosis. As deoxygenated blood reaches systemic circulation from the right ventricle cyanosis occurs. If the pulmonary stenosis is severe, less amount of blood reaches the lungs and the cyanosis also becomes severe. To compensate this, polycythemia may develop. Sometimes pulmonary blood flow may be increased by collateral circulation or patent ductus arteriosus.
Remington Stotler Advanced Adult Care Pre-clinical assignment Common Conditions: 1. Acute myocardial infarction/coronary artery disease is when the arteries that supply the myocardium are clogged up; the heart cannot pump blood effectively to adequately perfuse vital organs and peripheral tissues. It affects the arteries that provide blood oxygen, and nutrients to the myocardium. When blood flow through the coronary arteries is partially or completely blocked, ischemia and infarction of the myocardium could occur. Nitroglycerin (NTG) increases collateral blood flow, redistributes blood flow toward the sub endocardium, and dilates the coronary arteries.
Dryness causes the skin of the feet to peel or crack, which further make these body parts get easily sore and more prone to wounds or injuries. High blood sugar levels hamper a person's ability to ward off infection. It is therefore important for diabetics with foot problems to treat their infection not in the way it is normally done by persons without diabetes. Foot problems caused by diabetes are very slow to heal and, when infected, the wounds can eventually degenerate to gangrene. If the condition further worsens, amputation becomes necessary.
The patient might struggler gasping for air sometime. Any expression also could not be shown due to the weakness of facial muscles. In Class IV, the condition is worse. The ocular and other muscles that affected in this disease greatly become weaker. The eye, head, neck, hand and leg almost could not be used because the muscle cannot contract due to the weakness.
HEART FAILURE This is also referred to as Congestive heart failure. it is a clinical syndrome which occurs when the heart is unable to pump sufficient amount of blood to meet the metabolic requirement of the tissue for oxygen. It can also result from structural cardiac abnormalities which impair the ability of the ventricle to fill or eject blood. The heart is weakened and cannot pump enough blood as strongly as before this implies that less oxygen is reaching the organs and muscles which can cause tiredness or shortness of breath. Etiology of cardiac failure: • Systemic hypertension-The most common cause in 75% of cases • Changes in the structure of the heart -changes in the valves causes volume and pressure overload • Disease conditions-valvular
There are two types of white blood cells which are lymphocytes and phagocytes. When a person is under a condition of negative stress, his/her immune system’s ability to fight off antigens would reduce which results him/her more susceptible to infections. For example, my appetite tends to decrease before the exam period due to my stress on understanding every topic. With the decreasing of my appetite, it leads to poor nutrition and lack of nutritional energy which is used to support immune functioning and the function of the entire body. Therefore, stress weakens my immune system.
