Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

A

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

No interventions assigned to this group
