BMI: body mass index. SBP, MBP, DBP, and PP: systolic, mean, diastolic, and pulse blood pressure, respectively. AIx: augmentation index. cAIx and cAIx HR75: central (aortic) augmentation index net value and normalized for heart rate equal 75 beats/minute, respectively. Ao-PWV: Aortic pulse wave velocity. Min and Max: minimal and maximal value, respectively. A was considered statistically significant.
