Why the study?
Does left atrial size predict incident ischemic stroke and all-cause mortality in African Americans?
Does left atrial size predict incident ischemic stroke and all-cause mortality in African Americans?
Left atrial size is an independent predictor of all-cause mortality in African Americans, independent of traditional risk factors, LV hypertrophy, and low LVEF.
Answers are grounded in this paper and cite their sources.
May refine mortality stratification in African Americans; hypothesis-generating for stroke prediction and requires prospective validation.
In this population-based cohort of African Americans, LA size was a predictor of all-cause mortality after adjusting for traditional cardiovascular risk factors, LV hypertrophy, and low LV ejection fraction.
