Q

why would you avoid using pimobendan in a pt with HCM

A

heart is already enlarged, drug will cause increased contractability of the heart, more stress on the heart

21
Q

3 catecholamines

A

epinephrine, norepinephrine, dopamine

22
Q

why is epinephrine not given to treat heart failure

A

increases workload of the heart as well as increasing the chance of arrhythmias

23
Q

what happens when alpha 2 adrenergic receptors are stimulated

A

inhibition of release further norepinehrine from the nerve terminal

24
Q

why do we give animals with cardiomyopathies beta blockers

A

helps slow down the heart rate to allow a longer filling time and helps to prevent any arrhythmia formation

25
Q

what type of drug mimics the effects of epinephrine and norepinephrine in the body

A

adrenergic agonists / sympathetic drugs

26
Q

where are muscarinic cholinergic receptors found

on the organs they affect not skeletal muscles
