Myocardial relaxation is governed by the interplay of two macromolecular systems: (1) myofilaments and (2) calcium extruding pumps/exchangers. In myocardium from failing hearts, both systems act more slowly than normal, and cause relaxation to decele

An increase in vascular stiffness is a fundamental component of hypertension. Our hypothesis is that the increased large artery stiffness in hypertension is due in part to intrinsic properties of vascular smooth muscle cells (VSMCs). Adult spontaneou

Hypertension and aging are both recognized to increase aortic stiffness, but the underlying mechanisms are not completely understood. Most prior studies have attributed increased aortic stiffness to mechanical changes within the extracellular matrix

To determine whether catecholamines produce alterations in myocardial myosin-actin cycling kinetics, we investigated the effects of isoproterenol upon mechanical characteristics of constantly activated heart muscle thought to reflect crossbridge beha
