Differentiate myocardial ischemia from myocardial infarction?
Ischaemia is the lack of blood supply to a tissue which start anaerobic respiratory mechanisms. Infarction is cell death through apoptosis resulting from prolonged or severe ischaemia. Clinicaly myocardial infarction will be more painful and is unrelieved by rest. On ECG infarction will reult in ST segment elevation where ischaemia will result in ST segment depresion (unless it is a posterior MI!). In MI there will also be raised biochemical markers hours later such as creatine kinase and troponin.
How dangerous is ischaemia?
Ischaemia is a condition characterized by reduced blood flow to tissues, which can lead to tissue damage and, if prolonged, cell death. The danger of ischaemia depends on the location and severity; for example, cardiac ischaemia can result in heart attacks, while cerebral ischaemia can lead to strokes. Prompt medical intervention is crucial to restore blood flow and mitigate long-term damage. Without treatment, ischaemia can result in severe complications or death.
What is the difference between SCD and a heart attack?
A heart attack (myocardial infarction) is the result of a blockage in an artery which feeds the heart, so the heart becomes starved for oxygen.
What is a heart attack known as?
Acute Myocardial Infarction (AMI).
Insufficient blood supply in human body is referred as?
Ischaemia
What is septal infarct?
It's when the wall between the left and right ventricles of the heart has an infarction.
What is watershed infarction?
watershed infarction cerebral infarction in a watershed area during a time of prolonged systemic hypotension
Abbreviation for myocardial infarction?
The abbreviation for myocardial infarction is M.I.
What is septal wall infarct?
It's when the wall between the left and right ventricles of the heart has an infarction.
What is the term for lack of blood supply to a tissue or organ?
The term most often used is infarction for a complete lack of blood flow to a particular organ (most often used when referring to a muscle such as the heart or skeletal muscle), or ischaemia for severely reduced blood flow. If you are simply referring to a reduced amount of oxygen then tissue hypoxia may apply.
What is the difference between necrosis and infarction?
Necrosis means that a cell or a group of cells die due to injury (heat, pressure etc), diseases (infections), or other pathological state. The term "infarction" essentially is synonymous with "ischemic necrosis" which means necrosis (cell death) from the lack of blood (ischemia). Ischemia can be caused by the occlusion of the arterial supply or venous drainage for a particular tissue.
Can EEG confirm infarction?
EEG cannot confirm infarction, Only MRI CAN CONFIRM INFARCTION. EEG can only confirm epilepsy cidpusa.org
