What is SIHD? - answer It stands for SIHD. Its when the heart's O2
demand is greater than its supply
What are factors that affect O2 demand? - answer Wall tension
(BP/afterload, left ventricular volume/preload), contractility
strength, heart rate
What are factors that affect O2 supply? - answer O2 carrying
capacity, coronary blood flow
What are some symptoms of SIHD? - answer It presents as an
angina attack (lack of O2) similar to heart attack. Chest pain from
activity. SOB. Really only last 0.5-20 mins. Relieved by rest
What can cause angina attacks? - answer Exercise, postprandial,
cold weather, sex, emotional stress
What are modifiable risk factors? - answer Smoking, HTN,
dyslipidemia, DM, obesity, inactivity
What are non-modifiable risk factors? - answer Age, premature
family history
What are the goals of treatment for SIHD? - answer Reduce
symptoms: frequency and severity of angina, reduce occurrence of
ischemia (chest pain, QoL). Prevent progression: prevent
complications and death, minimize healthcare cost
, What are some ways to increase O2 supply? - answer Remove or
reduce clot, reduce coronary resistance
What are some ways to decrease O2 demand? - answer Reduce
heart rate, reduce contractility, reduce wall tension
What is the first step for treatment? - answer First step is to get
antiplatelet therapy (ASA 91 mg QD or clopidogrel 75 mg QD).
Determine if the patient should get one or both of the therapy using
the DAPT criteria.
How do you interpret the DAPT variables? - answer 2+ → DAPT, <2 →
just ASA
What is the duration of DAPT? - answer If DMS = 1 month. If DES
without high bleed risk = at least 6 months. If DES with high bleed
risk = DC after 3 months and swap to just ASA 81 mg QD. s/p CABG
= 12 months
What puts someone at a high bleeding risk? - answer Prior bleeding
on DAPT, coagulopathy, OAC use
What should be given to every patient for quick relief? - answer SL
NTG 0.15-0.4 mg PO PRN
After the antiplatelet and SL NTG, what should they get next? -
answer They should get a beta blocker. All beta blockers work
equally.
What is the target HR for beta blockers? - answer 50-60
