What is st elevation myocardial infarction?

What is st elevation myocardial infarction?

ST elevation...: Many believe that an st elevation myocardial infarction means that it is a transmural infarct (involving the whole thickness of the myocardium). Some people refer to nstemi (non st elevation myocardial infarction) as non-transmural infarct (not involving the whole thickness of the myocardium). These definitions are somewhat debatable but thought you may be interested. ...Read more

Myocardial Infarction (Definition)

Myocardial Infarction means some of the heart muscle dies because of insufficient oxygen supply. Most often this occurs because the coronary artery is blocked by plaque & clot. Other causes include tears in the artery wall, extremely high oxygen demand (eg, rapid arrhythmia, heart valve disorder, or severe systemic illness.) Prompt treatment can minimize heart damage & ...Read more

What's the meaning of "st elevation myocardial infarction (stemi)"?

What's the meaning of "st elevation myocardial infarction (stemi)"?

Severe Heart Attack: Heart attacks - the lay term for myocardial infarction - comes in two levels of severity. Non-st-elevation (nstemi) and st-elevation (stemi) which refer to changes on an ekg and broadly reflect if an arterial occlusion is total or subtotal. ...Read more

How are hemophilia, myocardial infarction (heart attack), and stroke related to blood clotting?

How are hemophilia, myocardial infarction (heart attack), and stroke related to blood clotting?

Opposites: Hemophilia is a defect of blood coagulation such that the blood does not clot. Heart attacks and strokes are a result of clots forming in the arteries feeding the heart and brain respectively. These latter clots can be formed locally due to damage to the blood vessels or an increased clotting tendency, or from clots that embolize from somewhere else in the body. ...Read more

Why is there ST segment elevation during a myocardial infarction?

Why is there ST segment elevation during a myocardial infarction?

Ecg: The ST segment elevation is caused by an electrical potential difference in that phase of the cardiac cycle between the dying cardiac muscle and normal parts of the heart and the vector direction of that potential difference as manifest on the ecg. ...Read more

Reason for st segment elevation in myocardial infarction?

Reason for st segment elevation in myocardial infarction?

Electrical: A heart attack damages muscles in the heart. The flow of the electrical current throughout the wall changes when having to go around the damaged muscle, resulting in certain ekg changes, since ekg's show the path of electrical current in the heart. There are different changes, de[ending on which part of the muscle is damaged. ...Read more

What is an unrecognized non-q-wave myocardial infarction?

What is an unrecognized non-q-wave myocardial infarction?

Q vs. Non-Q: When a heat attack causes a full thickness ("transmural") heart attack, the ekg reveals the resulting scar by inscribing a "q" wave in the leads that correspond to the damaged area. If the heart attack was not transmural or occurred in an area not seen well on ekg, there may be no q waves. If you had no symptoms at the time of the heart attack (25-50% of all attacks), it will be "unrecognized.". ...Read more

What is a st-wave myocardial infarction?

A myocardial infarction can be described as st elevation myocardial infarction or non-st elevation myocardial infarction depending on the appearance of the electrocardiogram. Management of the 2 types of heart attack are somewhat different. ...Read more

How do you prevent myocardial infarction?

Many approaches: There are many type of interventions to prevent heart disease. Eat a diet lower in saturated fats and chiolesterol. Increase your intake of fiber, fruits and vegetables. Start an exercise program, 30 minutes 5 days a week. See a doctor. Check your blood pressure, cholesterol and fasting blood sugar. Talk about family history. Know your risk levels and get started on therapies to modify them. ...Read more

St Elevation (Definition)

St elevations refers to a finding on an electrocardiogram, wherein the trace in the st segment is abnormally high above the isoelectric line. Ekg st segment elevation is usually attributed to impending infarction, but can also be due to pericarditis or vasospastic (variant) angina and early repolarization. In some healthy young adults, a form of st ...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
