Web2 de dez. de 2024 · Flow velocity may vary based on vessel properties and pathological changes 3,4. Low resistance vessels (e.g. internal carotid artery, renal artery) supply end organs which require perfusion throughout the entire cardiac cycle. These vessels exhibit high diastolic flow and EDV 4. WebILAi were therefore defined as the ratios between carotid stiffness parameters (PWVβ, Ep, β index) and blood flows in the ICA: Q-ICAd and Q-ICAm. 22, 23 All the ILAi were higher in the ILA group compared to the control group ( P <0.01), the most significant was PWVβ/Q-ICAd ( P =0.001). The results are shown in Table 2.
