This book discusses the evidence behind the relationship between COVID-19 and heart disease based on emerging state-of-the-art data. The rapid and unexpected global spread of the COVID-19 has revealed proportional levels of cardiovascular and metabolic complications. A myriad of pathogenetic mechanisms has come to the surface. There is still much research required to define whether cardiovascular disease causes COVID-19 complications or that cardiovascular disease appears as a result of the infection and which mechanisms are responsible. With cardiovascular and metabolic diseases already at pandemic levels and expected to increase further, this book provides readers with an urgent and thorough analysis of this association.
