Figure 5 Cardiovascular Event Rate as a Function of SE Results Across Quartile of Indexed LA Size

Stress echocardiography (SE) effectively risk stratified patients in each quartile of left atrial (LA) size (indexed). With increasing quartile group, the risk of cardiovascular events increased in both the abnormal and normal SE groups. The p values refer to the difference between the event rates in the normal versus abnormal groups for each quartile of the LA indexed size.
