Unchanged all-cause mortality in incident atrial fibrillation despite cardiovascular gains; extends evidence that noncardiovascular deaths now limit survival and warrants targeted study.
Despite improvements in cardiovascular mortality, overall 1-year survival in patients with incident atrial fibrillation has not improved due to a rising burden of noncardiovascular deaths.
