An in-silico analysis of experimental designs to study ventricular function: A focus on the right ventricle
PLOS Computational Biology.
Ed(s): A. Marsden
MeSH headings : Heart Ventricles; Humans; Hypertension, Pulmonary; Likelihood Functions; Research Design; Ventricular Dysfunction, Right; Ventricular Function
TL;DR:
A practical identifiability analysis of a multiscale cardiovascular model across four simulated experimental designs shows that model calibration to only RV pressure suffers from practical identIfiability issues and suffers from large forecast uncertainty in output space, but is substantially reduced once additional left ventricular pressure and volume data is included.
