Since more than 15 years, expert groups and various European Scientific Societies have written Guidelines on Cardiovascular Disease Prevention. Because of the rapid evolution of science, it is necessary to adapt regularly these guidelines. The last version dates from 2007 and has been written by the " Fourth Joint Task Force of European and other Societies on Cardiovascular Disease Prevention in Clinical Practice ". In this issue, the more recent Guidelines are summarised and we focus on highlighting the aspects of these Guidelines that have changed since the previous version published in this journal in 2005.
