Q

Aspirin at too high of doses is an issue because?

A

it will start blocking COX-2 and puts patient at actually a HIGHER thrombotic risk (we end up blocking some vasodilation)

Q

For SIHD pts getting an elective PCI: how do they utilize antiplatelets

A

They will do DAPT (dual antiplatelet therapy)
ASA 325 prior to PCI - then 81 mg QD for life
AND
Clopidogrel (300 - 600 mg before PCI) THEN 75 mg/day for either min. 6 mos (DrugElutingStent) or min. 1 month (BareMetalStent) – if major bleeding/high risk stop at 3 mos
*traditional to do clopidogrel for 12 mos

Q

For SIHD pts: if Pt gets a CABG what do they do for secondary prevention with antiplatelts

A

they do ASA 81 mg/day for life and clopidogrel 75 mg/day ~ 12 mos
(IF they had a PCI/stent before - they RESTART the 12 mos timeline after the CABG)

Q

why do DES need longer time on clopidogrel rather than the BMS

Q

if pt on DAPT (because of Stent/CABG) what do you do if they need non-cardiac surgery?

A

cant really stop DAPT…. defer the surgery as long as possible (6 mos to a year!!) only done if it is a life threatening surgery

25
if pt on DAPT (because of Stent/CABG) what do you do if pt requires anticoagulation?
use clopidogrel because it is less risky for pts that may have A.Fib, DVT, or PE prevention needs
26
if pt on DAPT (because of Stent/CABG) when would you use Ticagrelor/Prasugrel?
if pt cant do clopidogrel for some reason
27
if pt on DAPT (because of Stent/CABG) - what is risk scoring used for?
risk scoring helps you see how long they should be on DAPT - if overall score is > 2 - then ok/benfit vs risk is ok for prolonged therapy if overall score is < 2 ---- unfavorable benefit vs risk for prolonger therapy
28
``` ACEI are good for preventing ACS and death because.... they stabilize ________ improve ______ function inhibit _______ cell growth decrease ________ migration and possible ______ properties ```
``` stabilize PLAQUE improve ET function inhibit VSM cell growth decrease MACROPHAGE migration Anti-Ox properties ```
29
T or F: ACEI will improve symptomatic ischemia
FALSE! only for risk factor managing
30
T or F: ACEI should be used in all pts with IHD/CAD
TRUE (especially in HTN, DM, CKD, and LVEF < 40% patients!!)

what ACEI is best for preventing ACS and death
any of them!!!

beta blockers
33
``` Nitrates, B-blockers, DHPs, Verapamil, or Diltiazem: which one(s) will actually increase HR ```
nitrates; DHPs
34
``` Nitrates, B-blockers, DHPs, Verapamil, or Diltiazem: which one(s) will decrease HR really well ```
B-blockers and verapamil (diltiazem is decent-ish)
35
Nitrates, B-blockers, DHPs, Verapamil, or Diltiazem: | which one decreases systolic pressure the most?
DHPs
36
Storage facts for Nitroglycerin tabs
cannot keep them in weekly pill remainder crap; keep in original container has to be in easy open container
37
Nitro tabs: directions
take one tab - wait 5 mins - still angina? call 911 and take another; another 5 mins and STILL angina take another one MAX 3 tabs/day
38
counseling points for nitro tabs
``` SIT TF DOWN when taking it; vasodilation/may faint headache from it can increase HR (reflex tachycardia) keep on ya person all the time keep in dry location (not da bathroom) ```
39
what should patients take for their headache post nitroglycerin tabs
APAP
40
if pt has pretty large spike in HR after nitro tabs - what do ya do
lower da dose
41
PDE Inhibitors and Nitrates?
Hypotension from hell can happen aka do NOT take nitrate if had ingested a PDEI in past 24/48 hours
42
3 drugs used to PREVENT recurrent ischemia/angina symptoms
beta-blockers; CCBs; Nitrates
43
Beta-Blockers: | Reduce (venous or arterial BP) and thus decrease _____load

which beta blocker(s) are more lipid soluble
propranolol; metoprolol (aka liver excreted)
45
which beta blocker(s) are more water soluble

46
what are the 2 common cardioselective beta blockers
atenolol and metoprolol
47
atenolol and metoprolol are cardioselective --- but after about what dose do they become less cardioselective

which P2Y12 inhibitor do we avoid for STEMI treatments - and WHY
Clopidogrel; CYP2C19 genetic variations b/w patients can make toxicities harder to predict

62
what anticoags can be used in STEMI PCI Tx

two main ways to treat a STEMI
PCI OR Fibrinolytics
64

How to Choose b/w fibrinolytics for treating STEMI
no superior agent been defined - ALL WILL REDUCE MORTALITY! - Reteplase dosing is NON-wt based - Tenecteplase is single bolus (is controversial in pts > 75 yo)
