Tissue Doppler-derived index of left ventricular filling pressure, E/E′, predicts survival of patients with non-valvular atrial fibrillation
Why the study?
Does a higher E/E' ratio predict mortality and heart failure in patients with non-valvular atrial fibrillation?
Population
230 patients with non-valvular atrial fibrillation
Comparison
Higher E/E' ratio measured by tissue Doppler… vs Lower E/E' ratio (<= 15)
Design
Cohort
Follow-up

Implication
Should not yet change practice in non-valvular AF; hypothesis-generating for E/E'-guided management trials.
Structured PICO

P
Population

Higher E/E' ratio (> 15) measured by tissue Doppler imaging
C

The tissue Doppler-derived index E/E' is an independent predictor of mortality and heart failure in patients with non-valvular atrial fibrillation.
