  Introduction: Our aim was to assess by Tissue Doppler Imaging (TDI) the early left ventricular (LV) myocardial function abnormalities in obstructive sleep apnea (OSA). Methods: Thirty four patients (11 females, 23 males, aged 25-51) with newly diagnosed, nontreated OSA and normal echocardiographic parameters of LV diastolic and systolic function were investigated. The patients with known cardiovascular or respiratory disease were excluded. The LV end-systolic longitudinal strain (LS), peaksystolic longitudinal strain rate (LSR) and isovolumetric acceleration (IVA) of the septal and lateral mitral annulus was evaluated by TDI. Twenty two healthy persons (9 women, 13 men, and aged 23-48) were assessed as controls. Results: All OSA patients demonstrated significant decrease of the LV end-systolic LS: -15.7 ± 0...
