What does Subendocardial mean?
Medical Definition of subendocardial : situated or occurring beneath the endocardium or between the endocardium and myocardium subendocardial blood loss.
What does transmural mean?
: passing or administered through an anatomical wall transmural stimulation of the ileum also : involving the whole thickness of a wall transmural myocardial infarction.
What is the difference between a transmural and subendocardial infarction?
The transmural type usually consisted of yellowish-brown coagulation necrosis in the center of an infarcted focus and coagulative myocytolysis at the marginal zone. The subendocardial type was characterized by coagulative myocytolysis throughout the entire focus.
Where is the Subendocardium?
heart
The Purkinje fibers (Purkyne tissue or subendocardial branches) are located in the inner ventricular walls of the heart, just beneath the endocardium in a space called the subendocardium.
What is stemi and NSTEMI?
If there is a pattern known as ST-elevation on the EKG, this is called a STEMI, short for ST elevation myocardial infarction. If there is elevation of the blood markers suggesting heart damage, but no ST elevation seen on the EKG tracing, this is known as a NSTEMI.
What does non transmural mean?
For this study, a transmural infarct was defined as one that involves essentially the full thickness of the ventricular wall, and nontransmural was defined as something less.
What is non Caseating?
Medical Definition of noncaseating : not exhibiting caseation noncaseating granulomas.
Is there a difference between infraction and infarction?
An infarction is a blockage or obstruction. Infraction simply means ‘breaking. (Etymologically, it is derived from the same root as the verb ‘to infringe’.)
What does infarction mean in medical terms?
: injury or death of tissue (as of the heart or lungs) resulting from inadequate blood supply especially as a result of obstruction of the local circulation by a thrombus or embolus : the process of forming an infarct In myocardial infarction a coronary artery becomes obstructed and this leads to irreversible damage …
What is Subendocardial infarct?
Subendocardial infarction was defined as typical chest apin (greater than 15 minutes), serum enzyme elevation and persistent (greater than 48 hours) new T wave inversion and/or S-T segment depression in the absence of new pathologic Q waves.
What does transmural infarction mean?
Transmural infarcts involve the whole thickness of myocardium from epicardium to endocardium and are usually characterized by abnormal Q waves on ECG. Nontransmural (including subendocardial) infarcts do not extend through the ventricular wall and cause only ST-segment and T-wave (ST-T) abnormalities.
