Which option represents one of the three situations where anticoagulant therapy should not be interrupted?

• A. Patients on anticoagulant therapy for cardioversion
• B. Patients with a sprained ankle
• C. Patients with a skin infection
• D. Patients with a common cold

Answer: (A)

Continuing anticoagulation during procedures that carry a high risk of thromboembolism is essential, especially when cardioversion for atrial fibrillation is involved. In atrial fibrillation, blood can pool in the atria and form clots. If anticoagulant therapy is interrupted, those clots can still be there when the heart rhythm is restored, and they can be swept into the brain or other parts of the body, causing a stroke or embolic event. Keeping the anticoagulant going around the time of cardioversion helps protect against this risk and reduces the chance of a thromboembolism as the rhythm is converted back to normal. The other options describe minor conditions that do not inherently create a high risk of clot formation or stroke around a rhythm-control procedure, so there isn't the same justification to continue therapy specifically for those scenarios. As always, individual decisions should consider bleeding risk and the specifics of the planned procedure, but cardioversion in someone with atrial fibrillation is a well-recognized situation where uninterrupted anticoagulation is advised.
