    Study Notes

    Anticoagulants

    • Atrial fibrillation and GI bleeding: Apixaban is preferred anticoagulant over Warfarin, Heparin, or Dabigatran.
    • Heparin-induced thrombocytopenia (HIT): Fondaparinux is the appropriate alternative to heparin.
    • Warfarin vs. Dabigatran reversal: Dabigatran reversal uses idarucizumab, whereas warfarin reversal uses plasma.

    Antiplatelets

    • Aspirin to P2Y12 inhibitor: Switching is warranted if aspirin fails to prevent recurrent myocardial infarction.
    • Dual antiplatelet therapy (DAPT) adverse effects: A strategy of switching to low-dose aspirin and clopidogrel is recommended.

    Antihypertensives

    • ACE inhibitor-induced cough and CKD: Angiotensin receptor blockers (ARBs) are the best alternative.
    • Hypertensive crisis and pheochromocytoma: Alpha-blockers are the first-line treatment.

    Antihyperlipidemics

    • Statin intolerance and myopathy: PCSK9 inhibitors are the preferred alternative.
    • PCSK9 inhibitors vs. ezetimibe: PCSK9 inhibitors significantly reduce cardiovascular events compared to ezetimibe.

    Cross-Category Integration

    • Least likely drug-drug interactions: Aspirin, lisinopril, and atorvastatin combination.
    • High cardiovascular risk with diabetes and obesity: Start with lifestyle modifications followed by statins, then antihypertensives, and finally antiplatelets in a stepwise approach.
