STEMI/NSTEMI Flashcards
1
Q
Troponin I
A
<0.035ng/mL
Protein found in muscle cells;
Patient having MI may not necessarily have elevated troponins initially - therefore, they are drawn at 0 hours, then every 2 hours
Remains in blood for ~ 1 week
2
Q
Creatine Kinase MB
A
0-4.9ng/mL
Enzyme found in heart muscle
Elevated 4-6 hours after MI; peaks at 20 hours
Returns to normal after 48 hours
3
Q
normal PT/PTT
A
11-14 seconds
4
Q
normal anti-Xa
A
0.3-0.7IU/mL
5
Q
BNP (Brain Natriuretic Peptide)
A
<100pg/mL
Hormone made in the heart; indicates heart stress, correlated with heart failure
