acute coronary syndrome Flashcards
STEMI definition
“STEMI occurs when a coronary artery or one of the smaller branches that supplies blood to the heart becomes suddenly blocked by a blood clot, causing the heart muscle supplied by the artery to die”
NSTEMI/angina definition
In unstable angina and NSTEMI the blood clot causes a reduced blood flow, but not a total blockage so the heart muscle supplied by the affected artery does not die.
