Also known as<unk> 
33% with confirmed MI have no chest pain on presentation (especially older, female, DM, CHF)
5% of<unk>  will develop Cardiogenic Shock (60% mortality)
Age >65 with MI and anemia had 33% reduction in 30 day mort if transfused to keep HCT >30
Association between quantity of troponin and risk of death<unk>  includes Type 2 -Type 5 biomarker<unk> s
Type 1: Spontaneous Myocardial<unk> 
Atherosclerotic plaque rupture or intraluminal thrombus in one or more of the coronary arteries
Type 2: Myocardial<unk>  Secondary to an Ischemic Imbalance
Condition other than CAD contributes to an imbalance between myocardial oxygen supply and/or demand (e.g. coronary spasm, embolism, low or high blood pressures, anemia, or arrhythmias)
Type 3: Cardiac Death Due to Myocardial<unk> 
Sudden cardiac death with symptoms suggestive of myocardial ischaemia without elevated biomarkers
Type 4: Myocardial<unk>  Associated With Revascularization Procedure
4a: Related to PCI
4b: Related to Stent Thrombosis
Type 5: Myocardial<unk>  Related to CABG Procedure
