Evaluation of subclinical left ventricular systolic dysfunction in patients with obstructive sleep apnea by automated function imaging method; an observational study

Abstract

Longitudinal LV mechanics in OSA patients with normal LVEF are deteriorated in the subclinical stage being associated with the severity of disease. AFI can be used as an effective and safe method in the determination of subclinical myocardial dysfunction in OSA patients, because it is semi-automated and easy to use with a short analysis time.
