Q

Explain pathophysiology of heart failure.

A

CAD -> event (MI) -> ischemia (lack of blood flow) to heart -> myocardial cell death -> reduce ability for heart to pump correctly

Q

What is the difference between HFrEF and HFpEF?

A

HFrEF (EF <= 40%): heart failure with reduced ejection fraction: less blood is pumped out of ventricles because of weakened heart muscles that can’t squeeze well

HFpEF (EF >= 50%): heart failure with preserved ejection fraction: less blood fills the ventricle due to stiff heart muscles that cant relax normally causing ventricle area for blood filling is decreased

Q

Name drugs that will exacerbate HF via negative inotropic effects (HFrEF only)

A

Antiarryhtmics agents (except amiodarone and dofetilide)
BB (do not start bb is wet or exacerbation; benefits with certain agents long term)
Non-DHP CCB (diltiazem, verapamil)
Itraconazole

  • Inotropes act on your cardiomyocytes, the cells in your heart muscle. Positive inotropic drugs help your heart beat with more force. Negative inotropic drugs tell your heart muscles to contract with less force

Q

Why are guidelines for HF mainly focused on HFrEF and not HFpEF?

A

Limited data on hospitalizations and mortality for HFpEF
HFpEF recommendations currently surround treating HTN, controlling fluid overload, and treat co-morbid contributing disease states
*limited data on using aldosterone antagonists, SGLT-2 inhibitors, ARNi, or ARBs to decrease hospitalizations

Q

What is the potency of loop diuretics form lowest to highest?

Torsemide longer half-life of 12-16 hrs vs 4-6 hours with furosemide or bumetanide
Ethacrynic acid should only be used in those with SULFA allergy

36
How do you use CHA2DS2-VASc to recommend agent for anti-coagulation?
AF plus 2 lol more NON gender risk factors, >=2 Men, >=3 Women —> strongly recommmend AG AF plus 1 or more NON gender risk factors, 1 in men, 2 in women —> AG is preferred (no anti thrombotic therapy may be considered) AF plus 0 NON gender risk factors, 0 in men, 1 in women, no anti thrombotic therapy preferred
37
What is the HASBLED scoring system?
Tool to identify reversible risk factors for bleeds
38
What are the anti coagulation options for non-valvular AFIB?
Direct oral anticoagulants (DOAC) and warfarin
39
What does non-valvular AFIB mean?
In AF the absence of moderate to servere mitral stenosis or presence of a mechanical heart valve
40
What is TTR with Warfarin in AF?
goal time in therapeutic range (TTR) should be >= 70% If TTR ,65% consider DOAC strategies to improve TTR *SAMe-TT2R2 score can be used to predict those whose might do better on warfarin
41
What are DOAC recommendations based on risk factors?
HIgh risk of bleeding: Eliquis (apixaban), Savaysa (edoxaban), dabigatran 110 (European) High risk of GI bleeding: apixaban, dabigatran 110 High risk of stroke: dabigatran 150mg **Recommend AGAINST anti platelet therapy alone for most patients (aspirin should not be used alone for AF) Aspirin same bleed risk as apixaban, so bleed risk not a reason to choose aspirin over apixaban
42
What are the 4 DOACs? And what are there 4 indications
Apixaban, dabigatran, rivaroxaban, edoxaban Non-valvular AFIB VTE treatment CAD/PAD (to reduce the risk of heart attack, stroke, and CV death) VTE prophylaxis (TKR/THR FOR UP TO 35 DAYS OR REDUCTION IN THE RISK OF RECURRENT VTE FOLLOWING SURGERY UP TO 39 DAYS: XARELTO ONLY
43
Which is the only DOAC indicated for CAD/PAD and what is the dose?
Xarelto 2.5 mg PO BID plus ASA (75-100mg) QD CrCl <15 avoid use **only doses of 15/20 need to be taken with large meal
44
Which is the only DOAC indicated in non-valvular AFIB with ESRD/DIALYSIS patients?
Eliquis 5 mg PO BID reduce to 2.5mg PO BID if age >=80, TBW <=60kg
45
Which DOAC has acidic core?
Dabigatran Must store in original container, swallow whole do NOT crush
46
Which DOAC has real world data suggesting the highest association with higher rate of GI bleeds?
Xarelto, rivaroxaban
47
Which DOAC has the best safety profile with bleeding?
Eliquis, apixaban Don’t forget to dose adjust in older APPROPRIATE adults —> if patient >=80yo, TBW <=60kg, SCr >=1.5 (must have two)
48
Which DOAC should NOT be used in patients with CrCL >= 95?
Savaysa, edoxaban *dec efficacy with higher kidney function *For patients with 50 < CrCl <95
49
Which DOAC has an antidote? And what are the names of the antidotes?
Praxbind, idarucizumab for Pradaxa, dabigatran Anadexxa, andexanet alfa for factor Xa inhibitors (only FDA approved to be used with Apixaban and Rivaroxaban Prothrombin complex concentrate (PCC)
50
For a patient with AF and CKD do we anticoag knowing that with CKD, risk for bleed is higher?
Yes, we still do for renal patients, as bleed risk does get higher, stroke risk is even higher for these patients.
51
Can valvular AFIB patients take DOACs?
NO. Warfarin is only option.
52
What if AF patients get cardio version. Do they still get anticoag?
Yes, OAC for >= 4 weeks, or even longer based on stroke risk per CHA2DA2-VASc score
53
For lipid panels, fasting is not necessary unless the patient’s triglycerides are over 400. T/F?
True. Test results become more inaccurate when triglycerides are high for LFTs. Fasting still recommended for full work up
54
Which agent should be used to lower TG in older patients?
Vascepa, Lovaza, fenofibrate Between Vascepa and lovaza, Vascepa has more data to reduce CV event when used in addition to statin in those with TG >150 with CV disease or diabetes Lovaza has more TG lowering effects *vascepa is pure icosapent ethyl (highly purified fish oil), lovaza is a mixture
55
How do you calculate CHADS2Vasc?
Score of 2 or greater = anticoag CHF = +1 HTN = +1 Age >65 = +1, >75 = +2 Diabetes = +1 Sex (Female) = +1 Vascular disease = +1 Stroke/TIA = +2
56
What is treatment goal for afib?
To prevent stroke. Rate vs Rythym control
57
In afib what are the two options for treatment?
rate and rhythm control
58
In afib what are the two options for rhythm control?
Electrical or medication cardioversion
59
What are options for medication cardioversion?
flecainide, propafenone, dofetilide (Tikosyn), ibutilide, dronedarone (multaq)
60
In afib what are the options for rate control?
cardioselective BB: ie metoprolol non-dhp CCB: verap, diltiazem (work to slow the heart rate) digoxin
61
in afib, what is the medication used for rhythm control (not medication cardioversion)?
amiodarone
62
What boxed warning does amio have? what must you monitor with amio?
liver toxicity. TSH, lung function, LFTs QTC
63
T/F: digoxin can be used in both CHF and afib. In afib may have loading dose and target levels are higher.
True. levels are CHF vs afib = 0.5-0.8 vs 0.8-1.2 *can accumulate with worsening kidney function
64
What is TIMI risk scoring?
Used to determine the risk of ischemic events or mortality in patients who have unstable angina or NSTEMI, the higher the score, the more likely to use invasive strategies for revascularization with unstable angina and NSTEMI
65
What medications should patients be on for acute management of Acute coronary syndrome?
MONABS: morphine, oxygen, nitroglycerin, aspirin/antiplatelet, betablocker, statin
66
What medications should post MI patients be on?
acei/arb, BB, high intensity statin +/- ezetimibe, antiplatelet- mainly aspirin for secondary prevention, if aspirin not tolerated, clopidogrel, prasugrel, or ticagrelor
