Zusammenfassung
Introduction: Compromised cerebral autoregulation (CA) contributes to cerebrovascular complications in diabetic patients. In patients with diabetic cardiac autonomic neuropathy (CAN), standard methods of CA evaluation often fail to objectify the quality of CA. 0.1Hz sinusoidal neck suction (NS) is a refined technique to quantify CA using transfer function analysis and calculation of the gain and phase shift between NS induced blood pressure (BP) and cerebral blood flow velocity (CBFV) oscillations. Objective: To determine whether NS is suited to objectify CA in diabetic patients with CAN. Methods: In 9 type II d…
