Dynamic Echocardiographic Trajectory Phenotypes During Veno‐Arterial Extracorporeal Membrane Oxygenation and Their Association With In‐Hospital Mortality: A Multicenter Cohort Study

BACKGROUND: Current risk stratification for veno-arterial extracorporeal membrane oxygenation relies on static assessments, ignoring dynamic cardiac evolution. We aimed to identify longitudinal echocardiographic trajectory phenotypes and evaluate their association with in-hospita...

Environmental and system-level factors associated with emergency medical service utilization and immediate on-scene symptom response: a population-based study

Abstract Background Suspected cardiopulmonary emergencies represent a major component of EMS demand and are highly sensitive to environmental exposures. However, the combined impact of these dual macro-environmental and micro-operational stressors on prehospital treatment effecti...
