About

The purpose of this study is to determine whether patients with obstructive sleep apnea have any changes in left atrial morphology and function evaluated by echocardiography three dimensional

Full description

Several studies have been suggesting that Obstructive Sleep Apnea contributes to deterioration of left ventricular diastolic function . It may lead to atrial myocardium stretching and enlargement which may be associated to increased risk of cardiovascular events. We hypothesized that morphological and functional LA changes might be found using three dimensional echo, and that such alterations are related to obstructive sleep apnea presence.

Enrollment: 106 patients

Description:

The subjects for this group are matched for age, gender, body mass index. The presence of obstructive sleep apnea will divide the cohort in 02 subgroups: non-Obstructive Sleep Apnea and Obstructive Sleep Apnea
