Which statement identifies a situation in which anticoagulant or antiplatelet therapy should NOT be interrupted?

• A. Patients with prosthetic metal heart valves or coronary stents
• B. Patients with mild hypertension
• C. Patients who have had a common cold
• D. Patients on NSAIDs for headache

Answer: (A)

Continuing anticoagulant or antiplatelet therapy is essential when a patient has a prosthetic heart valve or a coronary stent because stopping therapy can lead to immediate and serious clotting events. A prosthetic valve can become obstructed by a thrombus if anticoagulation is paused, risking valve failure and embolic stroke. For a coronary stent, halting antiplatelet therapy greatly raises the chance of stent thrombosis, which can cause a heart attack or sudden death. These risks are typically deemed unacceptable, so the therapy should not be interrupted and should be managed carefully with the treating team, possibly using bridging strategies if a procedure is planned. In contrast, mild hypertension or a common cold do not entail the same immediate, high-stakes risk of catastrophic thrombosis if therapy is temporarily interrupted. NSAIDs for headache also pose bleeding considerations and may be adjusted around procedures, but the critical situation remains the high thrombotic risk associated with prosthetic valves and recent coronary stents.
