The document summarizes sessions from the European Society of Cardiology conference that focused on vulnerable plaque. Several sessions discussed ongoing research into the mechanisms of plaque inflammation and new markers of vulnerability. Emerging diagnostic techniques for detecting vulnerable plaque, such as thermography and elastography, were presented. The cardiology field is awaiting large clinical studies to evaluate the predictive value of these new diagnostic devices and provide guidance on risk stratification and treatment. The field of vulnerable plaque research is rapidly expanding and increasingly elucidating the underlying mechanisms of vulnerability.
