AI-Based Estimation of End-Systolic Elastance From Arm-Pressure and Systolic Time Intervals
Frontiers in Artificial Intelligence, 2021 Left ventricular end-systolic elastance (Ees) is a major determinant of cardiac systolic function and ventricular-arterial interaction. Previous methods for the Ees estimation require the use of the echocardiographic ejection fraction (EF).

Validation of a Non-invasive Inverse Problem-Solving Method for Stroke Volume
Frontiers in Physiology, 2022 Stroke volume (SV) is a major biomarker of cardiac function, reflecting ventricular-vascular coupling. Despite this, hemodynamic monitoring and management seldomly includes assessments of SV and remains predominantly guided by brachial cuff blood ...

Cardio-ankle vascular index (CAVI) measured by a new device: protocol for a validation study
BMJ Open, 2020 Introduction Cardio‐ankle vascular index (CAVI) is a new marker of arterial stiffness (AS) that can assess vascular wall stiffness in the aorta, femoral artery and tibial artery. CAVI is less affected by blood pressure at the time of measurement than the
