Influence of the Impact of arterial rigidity on central aortic pressure. Focus on the central augmentation index
106 patients with hypertension were examined using applana- tion tonometry. Hypertensive patients with low C_AI larger were shown to have higher peripheral blood pressure (BP) than central BP due to amplification and cardiac output raise as well as decline of augmentation grade. In the second group, increased HR-cor- rected central augmentation causes raise of central diastolic BP. Patient with high C_AI had more prominent increase of central sys- tolic pressure. In this group, high central BP was supported by increased augmentation grades, including HR-corrected to 75b.p.m., increased P_MAX_DPDT, and low amplification in other groups
