Background and aims: One of the main problems of health is Obstructive Sleep Apnea (OSA). The aim of the present study was to determine the effects of Continous Positive Airway Pressure (CPAP) on Left Ventricular (LV) diastolic function in patients suffering from OSA.
Methods: The study is a quasi-experimental clinical trial. In this study, 32 patients who have OSA and diastolic dysfunction at the same time selected by convenience sampling. Based on the results of polysomnography and echocardiography, patients undergo a period of 3 and 6 months using CPAP. They were reevaluated for LV diastolic function parameters using echocardiography.
Results: The evaluation of LV diastolic function parameters at the beginning and at the 3rd and 6th month of using CPAP shows that the late diastolic phase (Peak A) decreased and Premature ventricular diastolic filling rate during the phase values (Peak E), ventricular filling ratio of early to late phase during diastole E/A ratio and e' significantly increased (P<0.05).
Conclusion: The result of this study showed that after using CPAP in patients with OSA and LV diastolic dysfunction; the LV diastolic function parameters improved.
Keywords: Continous Positive Airway Pressure (CPAP), Obsrtuctive Sleep Apnea (OSA), LV diastolic function.
