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
right MI causes
conduction disturbances and mimics R-sided HF (JVD, hepatomegaly)
posterior MI blocks
left circumflex or right coronary artery
poster MI causes
SA and AV node issues
right ventricle infarct blocks
proximal right coronary
right ventricle infarct causes
effects function of right ventricle
