Implication

LAEF may aid differentiation of pseudonormal from normal mitral flow; leaves open its clinical utility in diastolic dysfunction assessment.

Structured PICO

Does left atrium emptying fraction (LAEF) differentiate between normal and pseudonormal mitral flow patterns in patients with suspected diastolic dysfunction?

Population

128 subjects, including 68 patients with echocardiographically determined diastolic dysfunction (mean age 53 +/- 13 years, 30 men, 38 women) and 60 healthy volunteers (mean age 49 +/- 12 years, 36 men, 24 women).

Intervention

Measurement of left atrium emptying fraction (LAEF), defined as the ratio of end-diastolic left atrial diameter to end-systolic diameter using the left parasternal long-axis echocardiographic window.

Comparator

Standard mitral flow Doppler parameters (E/A ratio, isovolumetric relaxation time, and deceleration time of E wave) and healthy volunteers with normal mitral flow.

Outcome

Left atrium emptying fraction (LAEF) across different diastolic function groups (normal, A>E, pseudonormal, restrictive).surrogate

Left atrium emptying fraction (LAEF) provides a simple echocardiographic method to differentiate normal from pseudonormal mitral flow patterns in patients with left ventricular diastolic dysfunction.
