STEMI

Question 1

STEMI

Answer 1

ST- elevation Myocardial Infarction

Question 2

What is Myocardial Infarction

Answer 2

Myocardial cell death due to prolonged ischemia

Question 3

difference between nstemi and stemi

Answer 3

stemi- development of full thickness cardiac muscle damage resulting from an acute interruption of blood supply to a part of the heart

nstemi- partial thickness damage of heart muscle

Question 4

pathophysiology

Answer 4

-Formation of an occlusive thrombus in a major coronary artery previously affected by atherosclerosis.
-Cholesterol deposition within the wall of the artery is the main mechanism of atherosclerosis.
-This deposited cholesterol ultimately forms a plaque in the wall of the artery called atherosclerotic plaque.
-Sometimes this plaquemay rupture or erode, and can trigger platelet aggregation and fibrin deposition, which lead to formation of an occlusive thrombus in a coronary artery.
-This occlusive thrombus completely blocks a coronary artery and interrupts blood supply to part of the myocardium
-Profound changes take place in the myocardium that lead to irreversible changes and death of myocardial cells and ultimately ST-segment elevation myocardial infarction develops.
