STEMI Flashcards
Which classification system uses history and physical findings to predict 30 day mortality in STEMI pts not undergoing reperfusion therapies
killip
Which classification system uses history and physical findings to predict 30 day mortality in STEMI pts receiving thrombolytic therapies
TIMI
The classification system that uses invasive hemodynamic data for prognosticating STEMI
forrester
Atypical presentations of STEMI are common in
women Elderly CKD Diabetes postop pts
Role of CK-MB in MI
Infarct within previous 48 hours
Periprocedural MI
Does a normal mediastinal width exclude aortic dissection
No,especially if clinical suspicion is high
Infarction of _____________ territory may be electrocardiographically silent
Left circumflex territory
Causes of ST elevation
MI myocarditis pericarditis LV aneurysm aortic dissection PE LV hypertrophy
role of GpIIb-IIIa inhibitors in MI
alternative to clopidogrel when surgical procedures are planned in ischemic MR,papillary muscle rupture,VSD
Contraindications to nitroglycerin use in acute MI
Hypotension (SBP < 90 mm Hg)
RVMI
HR greater than 100 or less than 50 bpm
Documented use of phosphodiesterase inhibitors
Role of morphine in MI
Chest pain refractory to nitroglycerin
IV beta blockers increase mortality in MI patients with
HF
Cardiogenic shock
age>70
SBP110
Most sensitive and specific lead for RVMI
RV4
lung fields are clear in RVMI except in
Large inferior infarct
MR
cause of recurrent chest pain in MI
Reinfarct
pericarditis
PE
Myocardial rupture
