Flashcards in ACS/AMI I Deck (27):
why do trops rise in NSTEMI?
exact definition of typical angina
2. worse w/ exertion or stress
3. relieved by NTG or rest
exact definition of atypical angina
chest pain with 2/3 characteristics of typical angina
(SSCP/discomfort, worse w/ exertion or stress, relieved by NTG or rest)
name 4 anginal equivalents
Classification system for MI
1- plaque rupture
2- supply/demand (spasm, HTN, arrhythmia, embolus)
3- SCA (no objective evidence)
4a- s/p PCI
5- s/p CABG
are elderly (>75) more likely to have STEMI or NSTEMI?
who has higher risk of In-Hospital mortality (elderly or young)
When choosing meds for elderly s/p ACS, what to watch out for?
calculate creatinine clearance
what are the two inflection point (in years) for closing of a SVG vs artery?
5 and 10 years
which pt pop is at high risk for coronary artery dissection?
what are the two local vasoconstrictors released from activated platelets?
who gets oxygen is NSTEMI/UA?
when O2 sat<90%
what med to discontinue in NSTEMI/UA?
TIMI risk score components
2. >3 CAD risk factors
3. prior obs CAD 50%
4. ASA in last 7d
5. >2 anginal events in 1d
6. ST deviation
7. high trop/CK
TIMI score of what is low risk?
GRACE score components
cardiac arrest at admission
what does GRACE score predict?
probability of in-hospital and 6 month mortality and MI
in TIMI score, what are the markers of highest risk (regardless of other factors)? which is worse?
3 factos contributing to myocardial oxygen demand
Wall tension (SBP, Vol)
Definition fo non-cardiac chest pain
Meets 1 or none of the angina criteria (SSCP/discomfort, worse w/ exertion or stress, relieved by NTG or rest)
definition of New onset angina
< 2 mo's, atleast CCS Class III (marked limitation with nl activity like 1-2 blocks or Flight of stairs).
3 A's of platelet activity
Adhesion, Activation, Aggregation
in a patient with suspected unstable angina, what serial test is important to do in ER?
how long after a pt has taken sildenafil or tadalafil do you wait until giving nitrates?
when is it recommended to give clopidogrel in UA/NSTEMI?
when pt is intolerant of ASA
for pt's with mild-mod CRI or DM and NSTEMI/UA, os conservative or early invasive strategy preferred?
