The Art-Heart Principle unifies cardiac spiral musculature, compression dynamics, and capillary design under one principle.
Proposes a unified theoretical framework for the structural design of the human heart, integrating macroscopic spiral musculature with microscopic capillary parameters.
The human heart is not arbitrary in its form. This paper proposes the Art-Heart Principle: the form that most efficiently delivers life force is simultaneously the form of greatest structural beauty. Cardiac spiral musculature (Torrent-Guasp, 2001), compression dynamics, and capillary-scale design parameters (7 micrometers capillary diameter: Rakusan et al. 1992; 1 mm myocardial layer: Vunjak-Novakovic et al. 2010) are unified under a single compression principle: v proportional to 1/N. The paper addresses designers including Kazuo Kawasaki's tradition of 'hi no utsuwa' (悲の器), bioengineers, and researchers building cardiac tissue constructs.
