Inclusion Criteria

Disorders are usually related with sleep apnea in patients with cardiovascular problems.
Objectives: To determine the effect of continuous positive pressure ventilation on left ventricular diastolic function in patients with obstructive sleep apnea is. Design: This study is a clinical trial.
Material and Method: In this study, 32 patients with concurrently obstructive sleep apnea and left ventricular diastolic dysfunction
echocardiographic evidence of left ventricular diastolic function disorder; Patients who used continuous positive pressure ventilation for at least an hour to be endured; During the four weeks before starting treatment, the patient does not any changes in the clinical comorbidity.
During the four weeks prior to treatment, there is no change in the patient's medications; Young and middle-aged adults.

Exclusion criteria: patients who are symptomatic obstructive sleep apnea; Morbid obesity, pregnant or breast feeding women; subjects who had severe heart disease during the past three months; Use less than 3/30 hours of continuous positive pressure ventilation during the night; During the six-month period of treatment, the patient is given a change in medication; Will be Checked by random sampling.

Interventions: based on the results of polysomnography and echocardiography of patients underwent a six-month period conditioning continuous positive pressure fall and after completion of the course of treatment again groups, before and after 6 months of diastolic function of the left ventricle echocardiography
