The document outlines the objectives, population, considerations, and process for the ACS Snapshot Survey/Registry study. The main objectives are to assess management and outcomes of AMI patients across European countries and regions in real-world practice settings. The study will enroll 3000-5000 consecutive AMI patients admitted to ICUs in Europe over a one-week period in December 2009. Participating sites will enter patient data into an online case report form to analyze management patterns and in-hospital outcomes.
