FoEM CBR22- Cardiology Exam What underlying pathologic process distinguishes myocardial infarction from angina/unstable angina? Atherosclerotic plaque rupture → exposed endothelium → clot attaches → reduced blood flow; if cell death occurs (usually due to complete vascular obstruction) then positive trop and MI; if no cell death occurs then negative trop and angina/unstable angina. What is the difference between transmural and nontransmural infarction? Transmural: usually STEMI, la...
