Left atrial function and mortality in the oldest old.

ABSTRACT:

Background

Previous studies demonstrated that left atrium (LA) size is associated with mortality in an elderly population. It remains unclear whether indices of LA function including reservoir, conduit, or booster elements of LA function provide incremental prognostic information.

Hypothesis

Echocardiographic measures of the various parameters of LA function would predict 5-year mortality in a community-dwelling population of 85 to 86 year olds independently of LA volume.

Methods

Subjects ages 85 to 86 years old underwent home echocardiography. LA volumes were assessed by the biplane Simpson's method from apical views using measurements of phasic volumes and functions of the LA, including LA expansion index. LA passive and active emptying fractions were assessed. Surv
