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.
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.
Benjamin et al. (1995) studied this question.
