What is the difference between atherosclerosis and myocardial infarction?
Myocardial ischemia occurs when blood flow to the heart muscle (myocardium) is obstructed by a partial or complete blockage of a coronary artery by a buildup of plaques (atherosclerosis). If the plaques rupture, you can have a heart attack (myocardial infarction).
What are the main causes of myocardial infarction?
Myocardial infarction (MI) usually results from an imbalance in oxygen supply and demand, which is most often caused by plaque rupture with thrombus formation in an epicardial coronary artery, resulting in an acute reduction of blood supply to a portion of the myocardium.
What is STEMI and Nstemi?
STEMI results from complete and prolonged occlusion of an epicardial coronary blood vessel and is defined based on ECG criteria..NSTEMI usually results from severe coronary artery narrowing, transient occlusion, or microembolization of thrombus and/or atheromatous material.
Which is worse STEMI or NSTEMI?
STEMI vs NSTEMI – Which is Worse? The bottom line is that both are just as bad. STEMI is seen as more of an immediate emergency because there is a known total occlusion of a heart vessel that needs opening back up urgently. In terms of long-term outcomes, they have equal health implications.
Is NSTEMI life threatening?
This condition gets its name because — unlike an ST-elevation myocardial infarction (STEMI heart attack) — it doesn’t cause a very specific, recognizable change to your heart’s electrical activity. Any heart attack, including an NSTEMI, is a life-threatening medical emergency and needs care immediately.
What is myocardial infarction?
A heart attack, or myocardial infarction (MI), is permanent damage to the heart muscle. “Myo” means muscle, “cardial” refers to the heart, and “infarction” means death of tissue due to lack of blood supply.

What are The racial predilections of myocardial infarction?
There are well-documented disparities in myocardial infarction survival by socioeconomic status, race, education, and census-tract-level poverty. Race: In the U.S. African Americans have a greater burden of myocardial infarction and other cardiovascular events.
What increases my risk for acute myocardial infarction?
Having high levels of cholesterol in your blood puts you at risk for acute myocardial infarction. You may be able to lower your cholesterol by making changes to your diet or by taking certain medications called statins.
