The cardiovascular system (CVS) is an essential component in  human health, as the background level of functioning of nearly all organs and systems depends on the blood supply level. It is of a very complicated dynamic mechanism by a type of the closed system of connecting vessels with variable parameters in all its structural segments – heart, vascular walls, as well as intravascular fluid – blood.

  1. An interesting article, which demonstrates that a lot of components of cardiac function are represented by optimal vortex formation in the blood flow has been recently published by Morteza Gharib and John O. Dabiri.

  2. The article published here by Lushchyk and Novytskyy points out nicely some of the shortcomings of current medical and also general views on the functionality of the human cardiovascular system, which has important consequences on medical practice and treatment in patients. In addition to these important aspects outlined by the authors, I like to point out the importance of taking also diurnal variations into account, meaning the circadian rhythm which is inherent in many cardiovascular and associated endogenous parameters. Without including internal circadian time into one’s considerations, one runs the potential risk to even declare someone ill who is healthy, by just measuring at the “wrong circadian time”.
