advanced exam 1- MI Flashcards
troponin t
found in heart muscles only when there is a lack of O2 to heart (coronary arteries)
troponin t onset
2-4 hours
troponin t peak
24-36 hours
troponin t elevation
10-14 days
troponin I
myocardial cells
troponin I onset
2-4 hours
troponin I peak
24-36 hours
troponin I elevation
7-10 days
creatinine kinase (CK-MB)
only when there is a decrease in O2
creatinine kinase (CK-MB) onset
4-8 hours
creatinine kinase (CK-MB) peak
12-24 hours
creatinine kinase (CK-MB) elevation
72 hours
myoglobin
protein that transports O2, cardiac skeletal muscle
myoglobin onset
1-3 hours
myoglobin peak
12 hours
myoglobin elevation
24 hours
troponin t (tnt) 0.030 ng/mL
no heart damage
troponin t (tnt) 0.03-0.099 ng/mL
possible heart damage
troponin t (tnt) >0.01 ng/mL
heart damage
anterior MI blocks
left anterior descending and part of intraventricular septum
anterior MI causes
decrease in BP, weak pulse, mimics L-sided HF (pulmonary edema)
lateral MI blocks
left circumflex artery
lateral MI causes
AV node blocks (slowing of conduction)
inferior MI blocks
right coronary artery
