Alexander B, et al. - Through a retrospective study of a total of 676 patients without previous atrial fibrillation (AF) who underwent coronary angiography, the researchers intended to generate an electrocardiographic risk score for new-onset AF. In comparison to the low-risk group, the high- and intermediate-risk groups were more likely to develop AF. The significantly shorter mean time for the development of AF in the high-risk group, in contrast to the intermediate- and low-risk groups was observed. Hence, for the prediction of new-onset AF, a simple risk score composed of easy-to-measure electrocardiographic variables could be used. Further, to determine the ability of this risk score in guessing AF in other populations, more validation studies would be needed.
