| Zahn's infarct | A pseudoinfarct of the liver, consisting of an area of congestion with parenchymal atrophy but no necrosis; due to obstruction of a branch of the portal vein. (05 Mar 2000) |
|---|---|
| uric acid infarct | <nephrology, paediatrics> Precipitates of uric acid distending renal collecting tubules in the newborn; since there is no necrosis, the term infarct is a misnomer. (20 Jun 2000) |
| anterior myocardial infarction | Infarction involving the anterior wall of the heart, and producing indicative electrocardiographic changes in the anterior chest leads and often in limb lead I. (05 Mar 2000) |
| anteroinferior myocardial infarction | Infarction involving both anterior and inferior walls of the heart simultaneously. (05 Mar 2000) |
| anterolateral myocardial infarction | Extensive anterior infarction producing indicative changes across the precordium as well as in leads I and aVL. (05 Mar 2000) |
| anteroseptal myocardial infarction | An anterior infarction in which indicative electrocardiographic changes are confined to the medial chest leads (V1-V4). (05 Mar 2000) |
| biopsy, myocardial | <investigation, procedure, surgery> A procedure which involves the removal of a small specimen of cardiac muscle tissue for microscopic analysis. This is generally performed at the same time as a cardiac catheterisation or as a very similar, yet separate, procedure. A small piece of heart tissue is taken via a small forceps inserted into the cardiac catheter site (usually threaded through a vein in the neck). This test may reveal the cause of a cardiomyopathy, myocarditis, amyloidosis or a heart transplant rejection. (21 Mar 1998) |
| myocardial | Refers to the heart's muscle mass. (09 Oct 1997) |
| myocardial biopsy | <procedure> A procedure which involves the removal of a small specimen of cardiac muscle tissue for microscopic analysis. This is generally performed at the same time as a cardiac catheterisation or as a very similar, yet separate, procedure. A small piece of heart tissue is taken via a small forceps inserted into the cardiac catheter site (usually threaded through a vein in the neck). This test may reveal the cause of a cardiomyopathy, myocarditis, amyloidosis or a heart transplant rejection. (27 Sep 1997) |
| myocardial bridge | A bridge of cardiac muscle fibres extending over the epicardial aspect of a coronary artery; this finding, in cases of sudden unexpected death, has led to speculation that cardiac contraction during exertion could constrict the coronary artery. (05 Mar 2000) |
| myocardial contraction | Contractile activity of the heart. (12 Dec 1998) |
| myocardial contusion | A bruise to the heart muscle, usually caused by a blunt force applied to the anterior thorax (motor vehicle accident). Commonly seen in association with a rib or sternum fracture. Complications include cardiac arrhythmias and death. (27 Sep 1997) |
| myocardial depressant factor | A low molecular weight peptide of about 800-1000 having a negative inotropic effect. It is released into the circulation during experimental haemorrhagic pancreatitis, severe ischemia, and postoligaemic shock. (12 Dec 1998) |
| myocardial diseases | Diseases of the myocardium. (12 Dec 1998) |
| myocardial infarction | A term used to describe irreversible injury to heart muscle. Synonym: heart attack. See: infarction. Common symptoms include substernal, crushing chest pain that may radiate to the jaw or arms. Chest pains may be associated with nausea, sweating and shortness of breath. Acronym: MI (27 Sep 1997) |
