Across two validation cohorts of over 22,000 patients, an AI score from overnight heart traces yielded hazard ratios of 2.03 and 2.72 for atrial fibrillation.Across two validation cohorts of over 22,000 patients, an AI score from overnight heart traces yielded hazard ratios of 2.03 and 2.72 for atrial fibrillation.
Among adults meeting sleep guidelines, modelling 30 minutes shifted from sleep to moderate-to-vigorous activity gave a hazard ratio (a comparison of death rates) of 0.80…Among adults meeting sleep guidelines, modelling 30 minutes shifted from sleep to moderate-to-vigorous activity gave a hazard ratio (a comparison of death rates) of 0.80 versus no shift.
