DOI: 10.1007/s10439-018-2072-0
Abstract: Although left ventricular end-systolic elastance (Ees) serves as a major index of cardiac contractility, a widely-accepted noninvasive estimation of Ees does not exist. To overcome this limitation, we developed a two-step inverse method that allows… read more here.

DOI: 10.1111/echo.14239
Abstract: Subclinical target organ damage (TOD) is an important long‐term complication of hypertension and is associated with cardiovascular events and death. Aortic‐flow propagation velocity (APV) is one of the arterial stiffness parameters. The aim of this… read more here.
