Effects of continuous positive airway pressure therapy on left ventricular function assessed by tissue Doppler imaging in patients with obstructive sleep apnoea syndrome

摘要

Aims In this study, we aimed to assess left ventricular (LV) systolic and diastolic functions by tissue Doppler imaging (TDI) in patients with obstructive sleep apnoea syndrome (OSAS) and to investigate the effects of 6 month continuous positive airway pressure (CPAP) on LV systolic and diastolic functions.
