Routine Non-Invasive Cardiac Imaging Indices Cannot Reliably Detect Elevated Left Ventricular Filling Pressure

Elevated left ventricular filling pressure (LVFP) (≥15 mmHg) is a haemodynamic marker of diastolic dysfunction measured invasively during cardiac catheterisation. Attention has recently been drawn to several studies using multivariate regression approaches to identify elevated LVFP using non-invasive imaging. This study investigated the utility of a regression model to estimate LVFP using routine two-dimensional echocardiography (2DE) parameters.
