The model was parametrized by stiffness/elastic recoil k, relaxation/damping c, and load x. These parameters were determined as the solution of m⋅d2x/dt2 + c⋅dx/dt + kx = 0, which is based on the theory that the E-wave contour is determined by the interplay of stiffness/restoring force, damping/relaxation force, and load. The PAH group had a significantly higher k and c versus the control group (182.5 ± 72.4 g/s2 vs. 135.7 ± 49.5 g/s2, p = 0.0232 and 21.9 ± 6.5 g/s vs. 10.6 ± 5.2 g/s, p <0.0001, respectively). These results show that RV has a higher stiffness/elastic recoil and inferior cross-bridge relaxation in the PAH group. Present findings indicate the feasibility and utility of kinematic model parameters for assessing RV diastolic function.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier","subitem_publisher_language":"en"},{"subitem_publisher":"World Federation for Ultrasound in Medicine and Biology","subitem_publisher_language":"en"}]},"item_10001_rights_15":{"attribute_name":"権利情報","attribute_value_mlt":[{"subitem_rights":"© 2019.
