After six years and the enrollment of over 200,000 patients, the CRUSADE national quality improvement and educational initiative ended on January 31, 2007. This date brought to a close an invaluable and unprecedented compilation of data on the management of patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS), as well as important data on a smaller but very contemporary cohort of patients with acute ST-segment elevation myocardial infarction (STEMI).
