    In patients with septic shock, the presence of an elevated heart rate (HR) after fluid resuscitation marks a subgroup of patients with a particularly poor prognosis. Several studies have shown that HR control in this population is safe and can potentially improve outcomes. However, all were conducted in a single-center setting. The aim of this multicenter study is to demonstrate that administration of the highly beta1-selective and ultrashort-acting beta blocker landiolol in patients with septic shock and persistent tachycardia (HR ae 95 beats per minute [bpm]) is effective in reducing and maintaining HR without increasing vasopressor requirements. A phase IV, multicenter, prospective, randomized, open-label, controlled study is being conducted. The study will enroll a total of 200 patients with septic shock as defined by The Third International Consensus Definitions for Sepsis and Septic Shock criteria and tachycardia (HR ae 95 bpm) despite a hemodynamic optimization period of 24-36 h. Patients are randomized (1:1) to receive either standard treatment (according to the Surviving Sepsis Campaign Guidelines 2016) and continuous landiolol infusion to reach a target HR of 80-94 bpm or standard treatment alone. The primary endpoint is HR response (HR 80-94 bpm), the maintenance thereof, and the absence of increased vasopressor requirements during the first 24 h after initiating treatment. Despite recent studies, the role of beta blockers in the treatment of patients with septic shock remains unclear. This study will investigate whether HR control using landiolol is safe, feasible, and effective, and further enhance the understanding of beta blockade in patients with septic shock

    Characterization of angiotensin-II effects on cerebral and ocular circulation by noninvasive methods

    Aims The role of the renin-angiotensin-system (RAS) in the cerebral and ocular circulation is still a matter of controversy. In vitro and animal data lead to partially contradicting results. However, direct investigation of locally generated angiotensin II (Ang II) in humans is not possible in vivo. Hence, we hypothesised that it might be possible to characterize local effects of Ang II by comparing systemic and local haemodynamic parameters during exogenous Ang II infusion
