The state of systolic and diastolic myocardial functions in patients with severe obstructive sleep apnea and their dynamics during CPAP therapy

Aim. To evaluate the change in parameters of systolic and diastolic myocardial functions patients with severe obstructive sleep apnea (OSA) syndrome before after CPAP therapy.
 Materials methods. Forty eight OSA aged 4574 years were examined. All underwent questionnaires, echocardiography tissue Dopplerography, speckle-tracking echocardiography. At end three-month course therapy, re-examined, followed by a comparative analysis data obtained.
 Results. In ejection fraction left ventricle amplitude displacement fibrous ring tricuspid valve significantly increased, which indicated an increase relative capacity ventricular myocardium. The performed therapy had positive effect on function myocardium both ventricles, was manifested ratio peak rates early late transmitral transtricuspidal flows. rate regurgitation pressure pulmonary artery decreased dynamics.
 Conclusion. use improves heart function, leads to decrease OSA. results obtained substantiate importance initiation complex treatment
