An irregular pulse and an incomplete anticoagulation plan
A fictional 71-year-old man has documented atrial fibrillation, hypertension, diabetes and a previous ischemic stroke. The teaching exercise supplies the traditional CHA2DS2-VASc components: hypertension one point, age 65 to 74 one point, diabetes one point and prior stroke two points. No heart failure, vascular disease or other additional component is supplied. A trainee calculates the total correctly but immediately writes a specific medicine dose without checking renal function, valve disease, bleeding history, interactions or the person’s preferences. The supervisor agrees that stroke prevention is important but separates the score calculation from a complete prescribing decision. The case does not provide a local treatment protocol or a patient-specific medication order.
1. What score follows from the explicitly supplied components?
Read the worked answer
One plus one plus one plus two equals five. Do not add points for conditions or age categories that were not supplied.
2. Why is the calculation not a complete prescription?
Read the worked answer
Stroke-risk assessment is only one part of selecting and monitoring therapy. The clinical team still needs valve, renal, bleeding, interaction and preference information and the applicable current framework.
