Popis: Objective: In this study, the associations between pulmonary artery stiffness (PAS) and aortic stiffness, left ventricular diastolic parameters, and left ventricular mass (LVM) index in moderate to severe obstructive sleep apnea syndrome (OSAS) patients without coexisting disorders were investigated. Methods: A total of 66 non-diabetic, non-hypertensive, and non-smoking volunteers were enrolled. Participants were categorized by apnea-hypopnea index (AHI; event/hour). The control group was defined as no OSAS: AHI15 (n=31). Echocardiographic and biochemical tests, including measurement of C-reactive protein (CRP), were performed. PAS (kHz/s) was calculated by dividing the maximal frequency shift of the pulmonary flow by the acceleration time. Results: PAS (kHz/s), obtained by echocardiography, was statistically significantly higher in the OSAS group than the control group (28+-5 vs 18+-4, p
