coronary heart disease Coronary heart disease is when our hearts blood supply is blocked by a build-up of fatty substances in the arteries. Over a period of time our arteries can become blocked by fats. Our arteries will then become narrow causing the amount of blood flow to our heart to be restricted. This can result in angina (chest pains). However if he arteries become completely blocked it can cause a heart attack.
This occurs because of the increased need for oxygen by the thickened ventricle and because of reduced blood flow to the coronary arteries. o irregular heartbeat which you may feel as palpitations. • If the narrowing is severe the left ventricle may not function properly and you can develop heart failure. This causes shortness of breath, tiredness, and fluid retention in various tissues of the body. See separate leaflet called 'Heart Failure'.
Invades nasopharynx where it replicates & spreads down to lower airway via aspiration of upper airway secretions. Causes necrosis of respiratory epithelium of small airways, peribronchiolar mononuclear infiltration & plugging of the lumens with mucus and exudate. The small airways become variably obstructed; this allows adequate inspiratory volume but prevents full expiration. This leads to hyperinflation & atelectasis. Serious alterations in gas exchange occur with arterial hypoxemia & CO2 retention resulting from mismatching of pulmonary ventilation (gas exchange w/in lungs) and perfusion.
Atherosclerosis is a type of disease in the blood vessels, mainly in the arteries. Smoking, not exercising, and being overweight are lifestyles that people chose to live and in which can cause atherosclerosis. Damage to the human body like smoking, is when the atherosclerosis disease starts. (Words of Wisdom Biology, 2012) * Why would atherosclerosis result in a heart attack? Provide a brief explanation based on how the heart functions.
Because of M.M.’s increased Kussmaul respirations he is unable to fully express carbon dioxide from his lungs causing the carbon dioxide concentration of the blood to increase and the pH to decrease causing acidosis. The physician will likely order a ventilation/perfusion (V/Q) lung scan and a continuous heparin
Cystic Fibrosis is a genetic, chronic and life threatening disease that affects the lung, digestive and reproductive systems. Cystic Fibrosis affects the cells that produce mucus and sweat and digestive juices. These secreted fluids are normally thin and slippery. But in cystic fibrosis, a defective gene causes the secretions to become thick and sticky. Instead of acting as a lubricant, the secretions plug up tubes, ducts and passageways, especially in the lungs and pancreas.
The extra fluids build up in the legs, lungs, liver and around the eyes. This condition is known as congestive heart failure (CHF). Cardiomyopathy is an acquired or inherited condition of the heart muscles. The heart muscles become thicker or enlarged thus decreasing the ability of the heart to pump enough blood through the body (American Heart Association, 2013). In this paper the writer describes the best approach to care for Mr. P, who is hospitalized with
This causes build-up of fluid in the lungs, liver, arm, and legs. When this happens there is a lack of oxygen and nutrition to organs. Heart failure can also occur when an infection weakens the heart muscles. Congestive Heart Failure is common is high blood pressure, long term alcohol abuse, disorders of the heart valves and coronary artery disease. You need to have a proper diet and get a lot of rest when you have CHF.
Other causes may heredity high cholesterol, tobacco abuse, obesity and high blood pressure. Alular heart disease is another common type of heart disease. Vault disease is characterized by damage to or a defect in one of the four heart Values, which are the mitral, arctic, tricuspid, or pulmonary. Some causes are rheumatic fever, bacterial endocardia, high blood pressure, a heart attack or
Its presence can be revealed by a chest pain similar to a building and often triggered by physical exertion (angina pectoris) or a heart attack. Atherosclerosis may affect other arteries, especially those of the brain, in this case there is an increased risk of stroke and those of the lower limbs, which involves a risk of reducing or stopping the traffic pressure at this level (ischemia). Risk factors for atherosclerosis (not limited to) are: older age, hypertension, increased total cholesterol (on the LDL cholesterol), HDL cholesterol decreased, diabetes, obesity (abdominal circumference greater than 102 cm in men and 88 cm for
