Rapid reperfusion of the infarct-related artery is the cornerstone of therapy for the management of acute ST-elevation myocardial infarction (STEMI). Canada's geography presents unique challenges for timely delivery of reperfusion therapy for STEMI patients. The Canadian R ESUM ELa reperfusion rapide de l'artère responsable de l'infarctus est la pierre angulaire th erapeutique de la prise en charge de l'infarctus aigu du myocarde avec el evation du segment ST (STEMI).

Out of hospital cardiac arrest (OHCA) is associated with a low rate of survival to hospital discharge and high rates of neurological morbidity among survivors. Programmatic efforts to institute and integrate OHCA best care practices from the bystander response through to the in-hospital phase have been associated with improved patient outcomes. This Canadian Cardiovascular Society position statement was developed to provide comprehensive yet practical recommendations to guide the in-hospital care of OHCA patients. Using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system recommendations have been generated. Recommendations on initial care delivery on the basis of presenting rhythm, appropriate use of targeted temperature management, postarrest angiography, and revascularization in the initial phase of care of the OHCA patient are detailed within this statement. In addition, further description of best practices on sedation, use of neuromuscular blockade, oxygenation targets, hemodynamic monitoring, and blood product transfusion triggers in the critical care environment are contained in this document. Last, discussion of optimal care systems for the OHCA patient is provided. These guidelines aim to serve as a practical guide to optimize the in-hospital care of survivors of cardiac arrest and encourage the adoption of "best practice" protocols and treatment pathways. Emphasis is placed on integrating these aspects of in-hospital care as part of a postarrest "care bundle." It is hoped that this position statement can assist all medical professionals who treat survivors of cardiac arrest.
