What are the differences between myocardial infarction and myocardial ischemia?

What are the differences between myocardial infarction and myocardial ischemia?

Ischemia: Ischemia is a term for tissue not getting enough oxygen (almost the same as not enough blood supply). Infarction is the end result of too much ischemia, it means death of the tissue. In other words infarction is the result of severe prolonged ischemia. ...Read more

Infarction (Definition)

When the blood supply of a tissue is compromised by whatever mechanism, the tissue will stop working and if blood flow is not restored, the tissue will eventually die ("infarct", both verb and noun). The clinical picture that runs with development of an infarct ("heart attack"; ...Read more

Small myocardial infarction with Small -medium pharmacologically induced myocardial ischemia in that distribution. What are the the implications?

Small myocardial infarction with Small -medium pharmacologically induced myocardial ischemia in that distribution. What are the the implications?

Reversible defect?: If you're describing what we term a "reversible defect", wherein the heart seems OK at rest and not OK when stimulated (by exercise or medication), then this would mean that area of the heart is still vulnerable to damage (heart attack). This needs to be addressed and treated. You may need cardiac catheterization to define the anatomy of the vessel supplying that area with blood. ...Read more

Does ischemia or thrombosis cause myocardial infarction?

Does ischemia or thrombosis cause myocardial infarction?

Ischemia vs MI: Cholesterol plaque develops in the heart arteries. Progressive narrowing - usually greater than 70% - can lead to lack of blood flow to the heart muscle during exercise or rest and causes angina or ischemia. Myocardial infarction is due to the rupture of a plaque which causes a blood clot to form (thrombosis) in the artery blocking blood flow to that area of the heart muscle which then dies. ...Read more

How is ischemia linked to myocardial infarction, along with thrombosis?

How is ischemia linked to myocardial infarction, along with thrombosis?

MI: Ischemia is a state of insufficient blood supply to an organ, in this case the heart. When the condition persists it causes death of the tissue/organ - myocardial infarction. The cause of limited supply can be a narrowing of the supplying blood vessel, a blood cloth (thrombosis), a combination of both, or an increased tissue energy need such as in fever/sepsis etc... ...Read more

Can any doc tell me what's the difference between myocardial infarction and myocardial ischemia?

Damage done: Myocardia ischemia means heart muscle not getting enough oxygen. Frequently this is angina. When the lack of oxygen is prolonged there is destruction of the muscle: this is a heart attack or myocardial infarction. ...Read more

What is the difference between a myocardial infarct, ischemia and angina?

What is the difference between a myocardial infarct, ischemia and angina?

Maybe very serious: Ischemia means an area of the heart is not getting enough blood usually because of a blockage in an artery. The severity depends on whether it is a major artery or not. An intact occurs when the artery is completely blocked and the muscle dies. Angina is the pain felt when ischemia occurs. ...Read more

Are myocardial infarctions curable?

Are myocardial infarctions curable?

No: A myocardial infarction is an acute event in which a portion of the heart is irreversably destroyed, usually by a blocked artery. The major lesson is that this damage is potentially avoided if people come to an er promptly when they have symptoms, which have been discussed elsewhere. We have a short time window to use modern treatment to save the heart and prevent complications and death. ...Read more

How can troponin help with myocardial infarctions?

Diagnosis: Since troponins measure damage to the heart muscle which occurs in a heart attack - the damaged/dying muscle will leak these into the serum which can be measured - they can be used to determine if a heart attack has occurred. ...Read more

The mortality rate for myocardial infarctions is what?

The mortality rate for myocardial infarctions is what?

Goes up with age: Numbers are approximate: (all comers)
<1980: 20 % mortality
1990: (with thrombolysis):10-15%
2000: (with pci):5-10%
2010: (with drug eluting stents):2-5%
the sooner one arrives, the lower the mortality. Age, lung, kidney and cerebrovascular disease increase mortality. Age is a factor but not as much as the above. ...Read more

Is there a connection with cholesterol and myocardial infarctions?

LDLHDLnotCholesterol: It have been known, for over 7 decades, that artery disease typically begins ~age 7, yet remains asymptomatic for decades; artery walls thicken & enlarge, not narrow. Events, including stenosis (narrowing), result from plaque rupture & clots. Optimize NMR particle test (hdl & LDL concentration, not cholesterol), keep hba1c low, optional ≤5.0%, sbp ≤120 mmhg, don’t smoke, exercise, avoid sugar, etc. ...Read more

Myocardial infarction causes?

Myocardial infarction causes?

Many poss causes: Almost all heart attacks are the result of fatty deposits on the inside of arteries that break open and cause clotting which will blocks the artery (and the blood from flowing to the part of the heart the artery feeds). Family history, fatty diet, smoking, high blood pressure, diabetes and other disorders can all contribute to this process. ...Read more

What confirms myocardial infarction?

Toponins, clinic, wall: Acute cardiogenic shock, . Ventricular arrythmias, infarct syndrome, flash pulmonary edema, wall motion abnormalities, syncope, presyncope, cardiac arrest, . It takes 4 hours for troponins to elevate after the infarct begins. That is why clinical symptoms dictate emergent coronary interventions. Troponins may still be normal within minutes of a life threatening myocardial infarct. ...Read more

I need to know what's an inferior myocardial infarction?

Heart attack: Inferior myocardial infarction is a heart attack on the bottom of the heart. This portion of the heart is frequently served by the right coronary artery but occasionally by the circumflex coronary artery. When the artery closes, the bottom of the heart does not get any blood, and the muscle of the heart is injured. ...Read more

I was wondering is angina pectoris and myocardial infarction the same disease?

Not: Angina means your heart isn't receiving enough oxygen to meet its needs. However, it's reversible. Mi means that the deficiency in circulation is so severe and prolonged that there has been irreversible heart damage with cell injury and death. ...Read more

Can I use herbalife niteworks for patient with acute anteroseptal wall myocardial infarction?

Safety is unknown: Herbalife has many products, and since they are not medications approved by the fda, herbalife products are probably not tested for interactions and side effects like real medicines are. So, that means nobody really knows what side effects there are. If an herbalife user hears of some interaction or thinks she is getting a side effect, she can visit her primary care doctor. ...Read more

Where do most myocardial infarctions occur?

Where do most myocardial infarctions occur?

Varies: You have three main blood vessels feeding the heart - the right coronary, left circumflex, and the left anterior descending arteries. Narrowing can occur in any of the vessels and can be significant in any one or combination of these vessels. Bypass of the left anterior descending artery has shown the best change for improvement in life expectancy. ...Read more

What is a myocardial infarction?

What is a myocardial infarction?

Heart stroke: A heart stroke is also known as a myocardial infarction or heart attack. A blood clot forms in a heart blood vessel. This cuts off flow to a part of the heart and that part dies. This can cause pain, rhythm and pumping disturbances. These things can result in disability or death. ...Read more

What is a myocardial infarction?

Heart attack: Myocardial infarction mean death ("infarction") of heart muscle (card ~heart and myo~muscle). This happens when the heart muscle is not getting the oxygen it needs over a relatively long period of time. This can happen from a narrowing of a blood vessel which reduces flow or from a suddenly, totally blocked vessel. The heart can't stop working, so that part keeps trying to pump blood until the the ...Read more

Multiple methods: Myocardial infarction (mi) is suspected by symptoms usually including chest pain. The conclusive diagnosis is established based on a combination of specific abnormalities of the electrocardiogram (ekg) and presence of certain heart enzymes that leak into the blood during an mi. The most common enzymes are called ck-mb and troponin. ...Read more
