acs Flashcards
anterior wall MI
LAD (left anterior descending) vessel, and left ventricle
inferior wall MI
RCA (right coronary artery) and right ventricle
posterior wall MI
LCx (left circumflex) or RCA vessel
type 1 MI
spontaneous MI (plaque rupture w/ thrombosis)
type 2 MI
MI secondary to ischemic imbalance (oxygen supply vs demand)
type 3 MI
MI resulting in death when biomarker values are unavailable (sudden cardiac death)
type 4a MI
MI related to PCI < 48 hours after (troponin rise as a complication of coronary intervention)
type 4b MI
MI related to stent thrombosis (clot forms within stent)
type 4c MI
MI related to stent restenosis (re-narrowing within stent)
type 5 MI
MI related to CABG <48 hours after (troponin rise as a complication of bypass surgery)
which enzymes are cardiac specific
CK-MB, troponin
troponin elevation
rises in 3-6 hours, lasts 10-14 days
CK-MB elevation
rises in 3-4 hours, lasts 24-36 hours
CK elevation
rises in 4-8 hours, lasts 36-48 hours
myoglobin elevation
rises in 1-3 hours, lasts 12-24 hours
