The European Society of Cardiology (ESC) is one of the leading international medical membership organisations in the world. A not-for-profit organization, ESC represents over 95,000 cardiology professionals, principally from across Europe and the Mediterranean basin, but also from the rest of the world. The ESC provides an array of educational and scientific activities, such as the continuous updating and production of Clinical Practice Guidelines, the organisation of educational courses and initiatives and run pan-European surveys on specific disease areas. The ESC also edits and publishes 9 of the world's leading journals on cardiology. In conjunction with its constituent bodies, the ESC holds regular subspecialty congresses, which are becoming increasingly popular within the profession. It also organises the annual ESC Congress, the largest medical meeting in Europe.
