Left Atrial Volume and Function Evaluation in Patients With Obstructive Sleep Apnea
Completed
- Conditions
- Sleep Apnea Syndromes
- Registration Number
- NCT00570115
- Lead Sponsor
- Associação Fundo de Incentivo à Pesquisa
- Brief Summary
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
- Detailed 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.
