Implication
May refine AF risk stratification in elderly patients; leaves open whether echo parameters should guide preventive interventions.
Structured PICO
Do echocardiographic parameters predict the risk of nonrheumatic atrial fibrillation in an elderly population-based sample?
P
Population
Elderly, population-based sample from the Framingham Heart Study
I
Intervention
Echocardiographic assessment (specifically evaluating left atrial enlargement, increased left ventricular wall thickness, and reduced left ventricular fractional shortening)
O
Outcome
Risk for nonrheumatic atrial fibrillationhard clinical
Echocardiographic parameters such as left atrial enlargement and left ventricular structural/functional changes provide independent prognostic value for predicting incident nonrheumatic atrial fibrillation in elderly patients.
