Chaos is a post-laminar state. Flow is chaotic before it becomes turbulent. It has interesting properties in the time domain but the question is - are these details relevant in the biomedical field, specially, in the flow of blood in an aortic/cerebral artery?
Thank you.
Chaotic (i.e. unstable) flow has a definite effect on endothelium cells and the media. It causes degenration of IEL and contributes to the pathogenesis of a number of vascular disorders. Check the attached articles for details.

From biomechanical point of view, concerning erytrocites life time (which is resulting in such phenomenon as hemolysys), the chaos, evidently, is an influence negative factor. You know that design of artificial heart valve and cardiovasccular prostheses presumes minimisation of turbulence to reduce the hemolysys. On another hand, non-laminar flow give us positive result expressing to weaking of arteries because take away deposites on the artery's walls.
