Association of Cumulative Systolic Blood Pressure with Left Atrial Function in the Setting of Normal Left Atrial Size: the Atherosclerosis Risk in Communities (ARIC) Study

Lower left atrial (LA) function is associated with increased risk for cardiovascular disease events; data on risk factors for impaired LA function are limited. We evaluated the effect of cumulative systolic blood pressure (cSBP) from midlife to older age on LA strain in adults with normal LA size.
