Letter by Sanna Regarding Article, “Prognostications of Fibrillations”
To the Editor:
We read with great interest the article by Silver and Windecker1 but were concerned about a mistake on the reference of our study. The last sentence at the end of the first paragraph states “Event Monitor Belt for Recording Atrial Fibrillation After a Cerebral Ischemic Event (EMBRACE) followed a small number of patients out to 3 years; the rate of atrial fibrillation was 30% in those with the implanted cardiac monitor and 3% in those who had routine monitoring.” However, these results correspond to the Cryptogenic Stroke and Underlying Atrial Fibrillation (CRYSTAL AF) trial, published by Sanna et al,2 not to the EMBRACE study.3 In fact, as pointed out earlier in the same paragraph, the EMBRACE study monitored patients for 30 days, not 3 years, with an external monitor, not an implanted cardiac monitor.
