Does left atrial enlargement predict the risk of stroke and death?
Does left atrial enlargement predict the risk of stroke and death?
Left atrial enlargement is a significant predictor of stroke in men and death in both sexes, highlighting its prognostic value beyond left ventricular mass.
LA enlargement may refine risk stratification beyond LV mass; leaves open causality and need for prospective validation before practice change.
After multivariable adjustment, LA enlargement remained a significant predictor of stroke in men and death in both sexes. The relation of LA enlargement to stroke and death appears to be partially mediated by LV mass.
