Q

A (acute/chronic treatment)

A

Aspirin- loading dose of 162-325 mg should be given in a chewable non-enteric coated tablet

24
Q

A (acute ONLY treatment)

A

Anticoagulant- IV unfractionated heparin for 48 hours or until PCI can be performed or SQ Enoxaparin for the duration of hospitalization or until PCI is performed

25
P (acute/chronic treatment)
P2Y12 inhibitor LOAD (acute)- Ticagrelor (180 mg), Prasugrel (60 mg), Clopidogrel (300-600 mg) are given as loading doses in acute treatment P2Y12 inhibitor MAINTENANCE (chronic) - ticagrelor 90 mg twice daily, prasugrel 10 mg daily, or clopidogrel 75 mg daily
26
B (chronic treatment)
Beta Blockers (Longterm Treatment) Patient on Beta Blocker at least 3 years/Indefinitely All beta blockers are okay Heart Failure With reduced Ejection Fraction: Metoprolol Succinate, Carvedilol, Bisoprolol
27
A (chronic treatment)
ACE/ARB (Longterm Treatment): Patient is on indefinitely If possible, all patients Patients with LVEF <40% Patients with HTN, DM, stable CKD
28
M (chronic treatment)
Mineralocorticoid Receptor Antagonist (Longterm Treatment): Should be on indefinitely Drugs: Spironolactone or Eplerenone Patients with EF <40% (on ACE and Beta Blocker) Contraindications: Serum Creatine: >2.5 mg/dl men and women >2.0 mg/dL-Potassium: >5mEq/L
29
Medications with Cardiovascular and Diabetes benefit
GLP1 Agonists SGLT2 inhibitors
30
Chronic coronary disease includes what patients?
1. Patients with stable angina 2. Patients discharged after ACS 3. Patients with atherosclerosis diagnosed via screening
31
What is the goal of therapy for patients diagnosed with CCD?
Prevent development of major adverse cardiovascular event (MACE) like a myocardial infarction (ACS), stroke, or death due to cardiovascular causes
32
What non-pharmacological management should occur for patients with CCD?
1. Multidisciplinary approach 2. Individualized education 3. Assessment of SDOH 4. Diet and physical activity 5. Tobacco cessation 6. Alcohol limitations 7. Attempt to avoid - cocaine, methampheatmines, opioids, marijuana
33
What lipid therapy should occur for patients with CCD not at very high risk?
1. High intensity statin, LDL-C reduction at least 50% 2. If high-intensity is not tolerate, moderate intensity is recommended 3. Max statin and LDL-C > 70 > add ezetimibe 4. On max tolerated statin and LDL-C < 100 mg/dL with fasting TG 150-499 mg/dL, add icosapent ethyl
34
What lipid therapy should occur for patients with CCD at very high risk?
1. High intensity statin, LDL-C reduction at least 50% 2. Max statin and LDL-C > 70 > add ezetimibe 3. On max tolerated statin and LDL-C < 100 mg/dL with fasting TG 150-499 mg/dL, add icosapent ethyl 4. If on max LDL-C lowering therapy and LDL-C 70 or greater or non-HDL above 100, a PCSK9 inhibitor can be beneficial
35
What antiplatelet therapy should a patient with CCD and no history of PCI receive?
Aspirin 81 mg daily
36
What antiplatelet therapy should a patient with CCD and a PCI receive?
DAPT for 1-6 months, then SAPT
37
What antiplatelet therapy should a patient with CCD and a CABG receive?
DAPT
38
Use this for intermittent anginal symptoms
SL Nitroglycerin
39
How do Beta-blockers work to decrease anginal pain?
Decreases HR and contractility, which results in a decrease in O2 demand (GOAL: HR: 50-60bpm; exercise HR: 100bpm) Antiarrhythmic and slow progression of plaque
40
Beta-blockers adverse effects
bradycardia, heart block, worsening HF, bronchospasm, cold extremities, fatigue, depression, reduced exercise tolerance, decreased libido, insomnia, impotence
41
Beta-blocker pearls
Must be tapered upon discontinuation Mortality benefit in HFrEF: bisoprolol, metoprolol succinate, carvediol Do not initiate while a heart failure exacerbation Reduce dose if pt experiencing exacerbation (try not to discontinue)
42
How to CCBs work for anginal symptoms?
Both DHP and non-DHP work Non-DHP: decreased HR and contractility → decreased O2 demand DHP: decreased afterload → decrease O2 demand
43
Avoid Non-DHP CCB in these scenarios
Concomitant beta-blocker, Severe LV dysfunction
44
When do you use ranolazine for angina?
Add on therapy or Patients who need an anti-anginal that has no impact on HR/BP
45
Ranolazine MOA
MOA: inhibits persistent/late inward Na+ current in the ventricles; also has anti-ischemic activity related to reduced accumulation of intracellular calcium.
46
Ranolazine adverse effect
QT prolongation
47
Ranolazine metabolism
CYP3A4, 2D6, pGp
48
How do we diagnose PAD?
ABI (ankle brachial index) -> ratio of blood pressure in ankles:arms < 0.9
49
When is Cilostazol recommended in PAD?
To manage symptoms and improve walking distance
50
What are the adverse effects of cilostazol? Why does this happen?
Headache GI upset/diarrhea= lots of vasodilation
51
How long does Cilostazol take to work
2-4 weeks or up to 12 weeks.
52
Cilostazol BBW
Contraindicated in patients with heart failure
53
For long-term treatment of PAD what drugs should be given to ALL patients?
1. Statin 2. BP control (ACEI/ARB preferred)
54
When is DAPT recommended in PAD?
After revascularization (aspirin + clopidogrel)
55
What medication should be given to all patients with acute limb ischemia?
Heparin
