How frequently does stroke represent the initial manifestation of atrial fibrillation?
Because stroke is an uncommon initial presentation of atrial fibrillation, population-wide AF screening efforts must be highly cost-effective to be justified.
We observed that stroke is an uncommon but measureable presenting feature of AF. Our data imply that emphasizing cost-effectiveness of population-wide AF-screening efforts will be important given the relative infrequency with which stroke represents the initial manifestation of AF.
Lubitz et al. (Fri,) studied this question.
