Key result
Elderly adults with heart failure had significantly worse left atrial emptying fraction (47.6%) compared to those free of cardiovascular disease or risk factors (55.2%, P<0.001).
Cross-Sectional (n=1,142)
Yes
Absolute Event Rate: 47.6% vs 55.2%
p-value: p=<0.001
In elderly adults, left atrial function is significantly impaired in those with prevalent heart failure, but remains preserved in those with hypertension despite left atrial enlargement.
No takes yet. Share an insight, caveat, or question.
LA emptying fraction reduction in elderly HF does not support practice change; leaves open its prognostic value in longitudinal studies.
Gonçalves et al. (2016) conducted a cross-sectional in Cardiovascular disease and heart failure (n=1,142). Heart failure vs. Free of cardiovascular disease or risk factors was evaluated on Left atrial emptying fraction (LAEF) (p=<0.001). Elderly adults with heart failure had significantly worse left atrial emptying fraction (47.6%) compared to those free of cardiovascular disease or risk factors (55.2%, P<0.001).
