Independent and incremental value of severely enlarged left atrium in risk stratification of very elderly patients with chronic systolic heart failure

Congestive Heart Failure, 05/11/2012

At the interactive stepwise model in the very elderly population, a severely enlarged left atrium, added to the model after clinical parameters and ejection fraction, moved the chi–square value from 20.7 to 25.8 (P=.048). RFP emerged as the single best predictor of all–cause mortality in the younger and intermediate ranges, whereas severely enlarged left atrium was the best predictor in the very elderly.
