lab testing Flashcards
- ST depression
- negative troponin
UA
- ST depression
- troponin
NSTEMI
- ST elevation
- troponin
STEMI
- diffuse ST elevation
- positional pain
- friction rubs
pericarditis
chest pain d/t partial blockage
exertional pain that goes away w/ rest or pain
stable angina
non-occlusive thrombus with normal cardiac markers but may show signs of ischemia on EKG
UA
occlusion causing mild tissue death and necrosis with elevated cardiac markers
NSTEMI
complete occlusion of large vessel with elevated cardiac markers
STEMI
what type of MI is this?
plaque rupture w/ acute coronary thrombus/occlusion
type 1
what type of MI is this?
oxygen supply/demand mismatch that could be d/t vasospasm, atherosclerosis,
type 2
what type of MI is this?
SCD (sudden cardiac death)
type 3
what type of MI is this?
post PCI
4
what type of MI is this?
post CABG
type 5
what type of MI is this?
post CABG
type 5
which cardiac biomarker
- preferred in MI dz
- regulatory proteins that control the interaction of actin and myosin
- values over 99% URL are abnormal
- unique to the heart
troponin I and T (Tn)
- use if troponin is not available
- may be useful for reinfarction
- if elevated but Tn is normal then likely noncardiac tissue
CK-MB (MB isoenzyme of creatine kinase)
two other tests that we used to use to eval ACS or MI
myoglobin
lactate dehydrogenase (LD)
Tn time of initial eval is ____
2 to 4 hrs
CK-MB time of initial eval is ____
4-8 hrs
Tn time to return to normal is ____
3-10 days
5 other causes of Tn elevation that are demand/type 2 MI
- Prnzmetal angina
- severe anemia
- hypo/hypertension
- tachyarrhythmias
- severe illness/sepsis
hormone released from ventricles related to their stretch, high filling pressure/volume
* used to see if DOE/SOB is from HF or how well HF tx is going?
brain natriuretic peptide (BNP)
BNP over ____ is indicative of HF
500
