Question
Answer
why was LDH isoenzyme 1 used?   it was around at day 7 unlike CK and could be measured  
🗑
how long do troponin I and T stick around   they stay around for just as long if not longer than LDH  
🗑
creatine kinase is composed of?   M and B subunits  
🗑
what CK is in the brain   CK-BB  
🗑
CK in the Heart   CK-MB and CK-MM  
🗑
CK in the skeletal muscle   CK-MM  
🗑
CK in tumors   CK-BB  
🗑
CK in smooth muscle   CK-BB  
🗑
how can you tell if there is muscular dystrophy   CK-MB and MM elevated  
🗑
Trauma would affect CK ?   MB (less than 1-2% total) and MM elevated  
🗑
what effect on CK would hypothyroid have   increased MM  
🗑
what affect on CK would stroke have   increased MM  
🗑
What effect on CK would psychosis have   increased MM  
🗑
how is cardiac muscle distributed with regards to CK   80% MB 20% MM  
🗑
when you have an MI what percent of total CK is CKMB   more than 3%  
🗑
Labor in the uterus would produce what effect on CK   elevated BB  
🗑
intestinal trauma would produce what CK   elevated BB  
🗑
Shock would increase CK ?   elevated BB and MB  
🗑
when would CK MB not be elevated   most cardiac conditions, pulmonary emboli, intramuscular injection  
🗑
how long after an MI is CK-MB elevated   2-8 hours after MI Peaks at 36 hours and is normal 2-3 days after that  
🗑
what are troponins   3 regulatory proteins bound to contractile apparatuses of striated muscle  
🗑
what troponins are cardiac markers   TnI and TnT  
🗑
what troponin is also made in the heart but is not specific   TnC  
🗑
where else is TnC found   in skeletal muscle (slow twitch)  
🗑
what other conditions could make CK-MB less specific   renal failure, skeletal trauma or disease  
🗑
how does the timing of troponins compare with CK and LDH   same speed as CK and same durations as LDH-1  
🗑
how does troponin last so long   continuous release not delayed clearance  
🗑
how high in magnitude does Troponin elevate compared to CK   same magnitude but much greater fold increase as troponin unlike CK does not have other factors elevating its baseline  
🗑
how likely is somone with incresaed troponin but no increase in EKG or CKMB to have an immenint event   high liklihood  
🗑
how specific are TnI and TnT for MI   not at all only specific for myocardial damage you need a history  
🗑
what are the three kinds of natriuretic peptide   A, B, C  
🗑
how do natriuretic peptides change with chronic heart failure   increase  
🗑
where are natriuretic peptides synthesized   in the atria and ventricles  
🗑
ANP is released from the ?   atria when there is distension  
🗑
BNP is relesed from the?   brain and ventricles when there is ventricular overload  
🗑
CNP is released from?   brain and CNS when there is endothelial stress  
🗑
Which natriuretic peptide corresponds with other tests diagnosing the severity of a heart conditino   BNP  
🗑
what is BNP used for   to monitor CHF therapy, diagnose heart failure, and determine prognosis with acute coronary symptoms  
🗑
