We hypothesized that continuous positive airway pressure (CPAP) therapy could improve sleep-induced left ventricular (LV) dysfunction in patients with obstructive sleep apnoea syndrome (OSA). The aim of this study was to investigate the effects of CPAP therapy on LV systolic dysfunction during overnight sleep in patients with OSA using two-dimensional speckle-tracking echocardiography (2DSTE).
