The pharmaceutical industry is evolving with the use of hiPSC-derived cardiomyocytes (hiPSC-CM) for in vitro cardiac safety screening. Traditional reliance on QT interval prolongation as a main cardiotoxicity marker is being challenged. In addition, Comprehensive In Vitro Proarrhythmia Assay (CiPA) initiative recommends using computer modeling and in silico platforms as more comprehensive approach for cardiotoxicity testing in conjunction with hiPSC-CM in vitro screening. Our study presents such an innovative platform that integrates in vitro hiPSC-CM propagation test with in silico models to assess cardiotoxicity. Utilizing the electrophysiological and morphological characteristics of hiPSC-CM, we offer a thorough evaluation of potential drug-induced cardiac risks by computer modelling. We show, using the example of lidocaine and other antiarrhythmics, that using a integrative experimental and computer platform, the possibility to correctly display the clinical manifestations of side effects in advance.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
