Sudden cardiac arrest care requires more than rapid response. It demands a coordinated system built around speed, teamwork and continuous improvement, according to insights shared at the American College of Cardiology conference, ACC.26.
During a presentation titled “High Performance, High Yield Systems for Sudden Cardiac Arrest,” Jason Grady, NRP, AACC, FSCAI, of Northside Hospital Heart Institute, outlined how health systems can improve survival rates by strengthening every link in the chain of survival, from 911 dispatch through post-cardiac arrest intensive care.
More than 350,000 out-of-hospital sudden cardiac arrests occur each year in the United States, with survival rates remaining around 9.1%, according to data presented during the session. Grady also highlighted ongoing disparities in outcomes and emphasized the need for standardized, systemwide approaches to care.
The presentation drew parallels to the evolution of STEMI care systems, including national initiatives such as the Door-to-Balloon Alliance, which helped reduce treatment delays and improve outcomes through coordinated protocols and multidisciplinary collaboration.
Grady explained that high-performance sudden cardiac arrest systems rely on coordinated efforts across multiple stages of care.
That begins with 911 communication centers, where highly trained dispatchers play a critical role in rapid recognition of cardiac arrest and telephone-assisted CPR instruction. Ongoing simulation training, benchmarking and performance measurement are key components of these programs.
Emergency medical services teams also play a central role by focusing on high-performance CPR, clearly defined team roles, early communication with emergency departments and continuous simulation-based training.
Within the hospital, emergency departments and cardiac catheterization labs must maintain structured workflows and resource readiness to rapidly deliver advanced therapies such as percutaneous coronary intervention, extracorporeal CPR and mechanical circulatory support.
Grady also emphasized the importance of multidisciplinary cardiac intensive care unit teams focused on treating post-cardiac arrest syndrome, managing neurological injury and supporting families through clear communication and shared decision-making.
Technology continues to play an expanding role in improving care coordination and quality review. The presentation highlighted tools, including electronic data integration, communication platforms and performance tracking systems, designed to streamline workflows and identify opportunities for improvement.
An example scenario presented during the session highlighted the complexity of care for sudden cardiac arrest. In this case, a patient arrived after an out-of-hospital cardiac arrest with return of spontaneous circulation, severe metabolic abnormalities, and signs of an acute heart attack, highlighting the urgency and coordination required across emergency response and hospital teams.
The session concluded with a focus on continuous quality improvement and collaboration.
“High-performance cardiac arrest care requires the same disciplined, system-level design that transformed STEMI,” Grady noted in the presentation summary. “Communities improve survival when every link in the chain of survival is coordinated and optimized.”
