|
reduce demand by HR, contractility, preload and afterload
increase supply by blood flow |
|
|
3 types of angina
|
stable, variant of spasm or prinzmetal, unstable
|
|
|
what is the underlying cause of stable
|
arthrosclerosis
|
|
|
how does drugs relieve variant and stable angina
|
stable- lower demand
variant- increase supply |
|
|
how does nitro decrease demand?
|
it dilates veins which deceases preload
|
|
|
how does nitro help variant
|
by relaxing spasm which increases O2supply
|
|
|
3 adverse effects of nitro
|
headache, ortho hypo, and rflex tachy
|
|
|
how to help reflex tachy after nitro
|
use BB or CCB
|
|
|
why and how are BB used
|
decrease demand, - HR and contractibility and used on fixed schedule not PRN
|
|
|
what can a CCB do?
|
help stable by decrease afterload by relaxing arterioles and reduce HR and contract
help variant by relax spasm- increase supply |
|
|
when to use dihydropyridine
|
when BB and CCB combined because these to intensify cardiosuppression
|
|
|
how to decrease risk of MI

|
example of dihydropyridine
|
Nifedipine, Amlodipine CCB
|
|
|
difference bt dihydropyridine and verapilmil and diltiazem
|
hydro (vasodilate only) affect VSM and other affect VSM and heart decreases HR, contract and AV
|
|
|
verapamil can cause
|
Av block, brady and bad for HF
|
|
|
adverse effect of CCB
|
reflex tachy esp. dihydropyridine
|
