Research Interests

  • Dynamic properties of sympathetic modulation of vascular tone

This research was among the first to demonstrate that vascular smooth muscle responds relatively sluggish to sympathetic α-adrenergic stimulation and that this sluggish vascular response determines the frequency of blood pressure Mayer waves (blood pressure oscillations at a frequency of 0.1 Hz in humans). These studies culminated in the discovery that enhanced blood pressure variability (e.g., caused by loss of baroreflex function) contributes to cardiac hypertrophy.

  • Role of endothelium-derived nitric oxide on blood pressure variability

This research discovered that endothelium-derived nitric oxide significantly contributes to blood pressure variability. The importance of these studies was that they created a scientific basis for the use of blood pressure variability to indirectly assess endothelial (dys)function.

  • Myogenic vascular function and autoregulation of blood flow

These studies demonstrated that a loss of myogenic vascular function in the cerebral circulation can contribute to the development of hemorrhagic stroke:

  • Non-invasive assessment of cardiovascular function

The HemoLab software that I developed for this purpose is freely available to anyone and is currently used world-wide by many investigators (http://www.haraldstauss.com/HaraldStaussScientific/hemolab).

  • Effects of vagal nerve stimulation on metabolic, hemodynamic, and inflammatory regulation

This research demonstrated that vagal nerve stimulation has differential effects on blood glucose levels depending on whether afferent or efferent pathways are activated by VNS. Furthermore, these studies demonstrated that chronic vagal nerve stimulation in hypertensive rats prevents deterioration of vascular function, possibly through anti-inflammatory actions.
