Researchers analyzed prospectively collected data from the American College of Cardiology National Cardiovascular Data Registry for 43,801 adult patients who presented with STEMI within 12 hours of symptom onset and underwent percutaneous coronary intervention (PCI) at more than 600 U.S. centers.
Median door-to-balloon time was 83 minutes (interquartile range, 62–109 minutes); nearly 60% of patients received intervention within 90 minutes of hospital arrival. Patients who had longer door-to-balloon times were older and had more comorbidities,…
