| heart failure | A condition where there is ineffective pumping of the heart leading to an accumulation of fluid in the lungs. Typical symptoms include shortness of breath with exertion, difficulty breathing when lying flat and leg or ankle swelling. Causes include chronic hypertension, cardiomyopathy and myocardial infarction. (27 Sep 1997) |
|---|---|
| heart failure cells | Macrophages in the lung during left heart failure that often carry large amounts of haemosiderin. See: siderophore. (05 Mar 2000) |
| heart failure in kids | <radiology> Primary cardiomyopathy, aortic outflow obstruction, coarctation, supravalvular aortic stenosis, valvular aortic stenosis, noncardiac lesion, asphyxia, TTN (transient tachypnea of newborn), perinatal brain damage (IVH) see also: neonatal congestive heart failure (12 Dec 1998) |
| hepatic failure | A condition of severe end-stage liver dysfunction that is accompanied by a decline in mental status that may range from confusion (hepatic encephalopathy) to unresponsiveness (hepatic coma). Other features include a mousy odour to the breath, difficulty with balance and walking, tremor and impaired speech. (27 Sep 1997) |
| prosthesis failure | Malfunction of implantation shunts, valves, etc., and prosthesis loosening, migration, and breaking. (12 Dec 1998) |
| high output failure | Heart failure in which, despite relative myocardial insufficiency and consequent congestive heart failure, the cardiac output is maintained at normal or supernormal levels, as is sometimes seen in emphysema, thyrotoxicosis, etc. (05 Mar 2000) |
| secondary failure | Failure of the function of an organ as a result of antecedent pathology elsewhere, decreasing responsiveness to a drug after an initial satisfactory response, usually occurring several months after initiation of treatment. (05 Mar 2000) |
| pump failure | A term used to emphasize mechanical default of the heart as a pump; in acute myocardial infarction, pump failure signifies congestive heart failure, pulmonary oedema, or cardiogenic shock. Compare: electrical failure. Synonym: power failure. (05 Mar 2000) |
| neonatal heart failure | <radiology> most likely cause, premature: patent ductus arteriosus, full term: hypoplastic left heart, 2nd week: coarctation and VSD aetiology, valvular stenosis, mitral stenosis, aortic stenosis, aortic coarctation, vein of Galen aneurysm, infantile haemangioendothelioma of liver, hypoplastic left heart see also: congestive heart failure in kids (12 Dec 1998) |
| dental restoration failure | Inability or inadequacy of a dental restoration or prosthesis to perform as expected. (12 Dec 1998) |
| ovarian failure, premature | Premature failure of ovulation associated with hypergonadotropinism and hypoestrogenism in women under the age of 40. The aetiology appears to be multifactorial and many cases are idiopathic. When follicles are present but the ovaries are unable to respond to gonadotropins, resistant ovary syndrome results and this may be associated with autoimmune disease. Even when there is a loss of ovarian follicles, it is not always complete. Permanent and irreversible loss of follicles is termed premature menopause (menopause, premature). (12 Dec 1998) |
| electrical failure | Failure in which the cardiac inadequacy is secondary to disturbance of the electrical impulse. (05 Mar 2000) |
| treatment failure | A measure of the quality of health care by assessing the unsuccessful results or consequences of management and procedures used in combating disease. (12 Dec 1998) |
| equipment failure | Failure of equipment to perform up to standards. The failure may be due to defects or improper use. (12 Dec 1998) |
| equipment failure analysis | Determination of reliability and maintainability of equipment. (12 Dec 1998) |
