What is myocardial occlusion?
Myocardium. Coronary artery occlusion causes heart tissue damage due to ischemia and can lead to myocardial infarction (MI). The immediate and common cause of artery obstruction is formation of a thrombus.
What is Omi cardiology?
OMI is defined as acute coronary occlusion or near occlusion with insufficient collateral circulation where without emergent catheterization and reperfusion myocardium will undergo necrosis.
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.
How accurate is the use of ECGS in the diagnosis of myocardial infarct?
As part of the Myocardial Infarction Triage and Intervention Project, the investigators found that when compared with a single ECG, serial exams increased the diagnostic sensitivity for acute coronary syndrome from ~34% to 46% with a reduction in specificity from 96% to 93% and positive predictive value from 88% to 84% …
What causes coronary occlusion?
Most occlusions are caused by either a blood clot or the buildup of fatty plaque in the arteries (atherosclerosis). A blood clot can form at the site of occlusion, or it can travel from another area through the bloodstream and block an artery. That runaway clot is called an embolism.
What does it mean coronary occlusion?
: the partial or complete blocking (as by a thrombus, by spasm, or by sclerosis) of a coronary artery.
Is myocardial infarction a stroke?
This is a heart attack, also known as myocardial infarction (MI). When the blood supply to the brain is interrupted, causing a part of the brain to die, it’s called a stroke, or “brain attack.” Stroke is similar to a heart attack, but it affects the blood vessels in the brain instead of the heart.
Where is the OM1 coronary artery?
The first obtuse marginal artery (OM1) is usually found on or close to the obtuse margin of the heart and is also known as the “margo obtusus”.
Are ECGs reliable?
An ECG is pretty accurate at diagnosing many types of heart disease, although it doesn’t always pick up every heart problem. You may have a perfectly normal ECG, yet still have a heart condition.
Can ECG detect myocardial infarction?
Diagnosis of myocardial infarction is confirmed based on clinical manifestations and electrocardiographic changes along with increased cardiac enzymes. Electrocardiogram (ECG) is one of the safest and easiest methods in the first place.
What does FTT stand for in medical category?
Failure to thrive. Jump to navigation Jump to search. Failure to thrive (FTT) indicates insufficient weight gain or inappropriate weight loss in pediatric patients unless the term is more precisely defined.
What is the medical definition of occlusion?
Medical Definition of occlusion. 1: the act of occluding or the state of being occluded : a shutting off or obstruction of something a coronary occlusion; especially : a blocking of the central passage of one reflex by the passage of another.
What causes failure to thrive ( FTT ) in humans?
Failure to thrive. Milk allergies can cause endogenous FTT. Also the metabolism may be raised by parasites, asthma, urinary tract infections, and other fever-inducing infections, hyperthyroidism or congenital heart disease, so that it becomes difficult to get in sufficient calories to meet the higher caloric demands.
What is the treatment for portal hypertension ( FTT )?
Portal hypertension requires shunt placement to divert blood flow, and variceal bleeding is treated with vasoconstrictor drugs, balloon tamponade, vitamin K administration, and perhaps surgery (to ligate bleeding portal vein collateral vessels).
