About CardioNetworks

Welcome to

The CardioNetworks Foundation is a non-profit organization founded in 2007 and based in The Netherlands. The goals of the Foundation are: “to improve medical knowledge, especially in the field of cardiology, and to provide access to this knowledge by facilitating publications in digital or other form, amongst other means by building and maintaining websites.” All revenues are spent in the pursuit of this cause.
