Atrial fibrillation is an identified risk factor for ischemic strokes. Thus, the dynamics of heart rate under fibrillation might provide a useful predictor for strokes. The complex, nonlinear and multiscale nature of the heart rate calls for the use of powerful signal processing techniques. We explored the application of a novel tool, the scattering transform, to discriminate and predict ischemic strokes from heart rate dynamics. We found that groups of scattering coefficients, at several time scales, were significantly higher (p-value < 0.05) in patients who developed ischemic strokes than in those who did not. We also found significant differences in predictive power (C-statistic) between scattering coefficients and the CHA2 DS2-VASc score. Results suggest the use of scattering coefficients for the analysis of patients with atrial fibrillation.
