[Biomechanical porperties of the human coronary arteries].

Biomechanical properties of the coronary arteries were studied according to age and localization of the vascular segment. Experiments were conducted on the proximal and distal segments of the right coronary artery and the anterior descending branch of the left coronary artery in 58 males who ranged in age from 15 to 83 years. Vascular segments prestretched in the longitudinal direction experience an inner pressure of 0 to 240 mm Hg.
