Overview

LAA-TDI-D2 reduction was associated with PAF in hypertension; leaves open its predictive utility pending prospective studies.

Structured PICO

Does tissue Doppler imaging of the left atrial appendage identify predictive parameters for the onset of paroxysmal atrial fibrillation in patients with untreated hypertension?

P
Population
84 untreated hypertensive patients, comprising 57 with paroxysmal atrial fibrillation (PAF) and 27 age- and sex-matched subjects without PAF.
I
Intervention
Transesophageal echocardiography with tissue Doppler imaging of the left atrial appendage (LAA).
C
Comparator
Untreated hypertensive patients without paroxysmal atrial fibrillation.
O
Outcome
LAA emptying velocity (LAA-PW D2) and tissue Doppler contracting velocity of LAA (LAA-TDI-D2).surrogate

Tissue Doppler imaging reveals deteriorated left atrial appendage contracting function in hypertensive patients with paroxysmal atrial fibrillation despite normal global left atrial functions, suggesting its utility as a predictive marker.
