Q- A 75-year-old man presents to his physician for a routine examination. He has a history of hypertension, hypercholesterolemia, and osteoarthritis. He takes atenolol, simvastatin, and ibuprofen as needed. His pulse is 76/min and irregular. Blood pressure is 130/74. Physical examination and imaging studies are normal except for asymptomatic atrial fibrillation.
What is the next step in managing this patient?
A- Assurance and follow-up in 3 months
B- Start aspirin
C- Start heparin
D- Start warfarin
E- Start low molecular weight heparin and warfarin
Answer and Explanation
According to the most recent studies, warfarin 5 mg/day is the drug of choice for asymptomatic atrial fibrillation. AF in elderly patients carries a high stroke risk and should not be observed without anticoagulation. Aspirin is not sufficient for stroke prevention in atrial fibrillation.. Initial therapy with heparin is used for acute anticoagulation, not long-term outpatient management. Bridging is unnecessary in stable, nonvalvular AF without acute thrombosis.
The correct answer is D
Key takeaway:
👉 Elderly patient (≥75) with atrial fibrillation → start long-term oral anticoagulation (warfarin).

A great question Dr Kavz. Shin necrosis is a hypothetical outcome but not seen clinically. Anyways, this option of bridging warfarin with heparin early in the treatment is not one of the choices so, I think in this case the best answer is to start warfarin. Thank you for this good question.
Sir, If we start warfarin without starting heparin first don’t they have the risk of skin necrosis
