The emerging role of heart‐on‐a‐chip systems in delineating mechanisms of SARS‐CoV‐2‐induced cardiac dysfunction

Abstract

AbstractCoronavirus disease 2019 (COVID‐19) has been a major global health concern since its emergence in 2019, with over 680 million confirmed cases as of April 2023. While COVID‐19 has been strongly associated with the development of cardiovascular complications, the specific mechanisms by which viral infection induces myocardial dysfunction remain largely controversial as studies have shown that the severe acute respiratory syndrome coronavirus‐2 can lead to heart failure both directly, by causing damage to the heart cells, and indirectly, by triggering an inflammatory response throughout the body. In this review, we summarize the current understanding of potential mechanisms that drive heart failure based on in vitro studies. We also discuss the significance of three‐dimensional heart‐on‐a‐chip technology in the context of the current and future pandemics.
