Angina - Medications Flashcards
Nitrates - first line for ? ? is ? GTN spray
- sit down, ? and spray ? beneath tongue, wait for ? then spray again if still pain - if still at ? then call 999 and unlock the door
- can also use ? angina provoking activity
- they reduce ? to heart by causing ?
- can cause venous ? on standing -> ? hypotension and ?
- also affect large muscular aa -> reduce ? pressure and cardiac ?, they also dilate ? vessels
- reduced pre-and-after-load decreases ? req of myocardium -> coronary ? leads to increased ? delivery
- also relieve coronary artery spasm in ? angina
Sx relief sublingual rest once 5m 10m before preload venorelaxation pooling postural dizziness aortic afterload coronary o2 dilation o2 prinzmetal
BBs
B1 adrs mostly on ?, acting to incr ? and ?
B2 adrs cause ? ? relaxation in many organs eg trachea
in IHD - ? selective BBs used to ? cardiac rate and force (due to reduced myocardium ? consumption) with as little ? constrictive effect as possible
they also have an anti-? effect by reducing cardiac ? and decrease ? release from juxta-glomerular cells
they also have class two anti-? effects
heart SV + HR SM B1 reduce o2 broncho HTN output renin arrhythmic
BBs SE
- ? - CId in ? caution in COPD
- cardiac depression/? - can be critical if combined with other ? limiters
- ? - impair the ? warning signs of ?’s
- fatigue
bronchoconstriction asthma brady rate hypose sympathetic hypose
CCBs
dihydropyridines (amlodipine/?) or RL agents (verapamil/?)
all prevent ? ? contraction, reducing ? and causing ? vasodilatation
RL agents also on ??? to control the ??
SE - ? and headache (as with all ?), ? swelling and constipation (GI SM ?)
first line in ? angina
nifedipine diltiazem SM afterload coronary AVN HR flushing vasodilators ankle inhibition prinzmetal
Nicorandil
causes marked ? - used in ? angina
vasodilation
refractory
