Is left atrial enlargement associated with an increased risk of ischemic stroke in an ethnically mixed population?
Left atrial enlargement is an independent risk factor for ischemic stroke, particularly in men, whereas in women the association is attenuated by other factors such as left ventricular hypertrophy.
Left atrial enlargement is associated with an increased risk of ischemic stroke after adjustment for other stroke risk factors, including left ventricular hypertrophy. The association is observed in men of all ages, whereas in women it is attenuated by other factors, especially left ventricular hypertrophy. Interracial differences in the stroke risk may exist that need further investigation.
Tullio et al. (Fri,) studied this question.
