Door-to-balloon time in USA

What are the current guidelines for door-to-balloon time for PCI? What is the average door-to-balloon time in the United States?

Ans: Current guidelines from the American College of Cardiology call for a time of less than 90 minutes from the first medical contact to inflation of the balloon. In the United States, the average door-to-balloon time for patients who require a hospital transfer for PCI is 139 minutes. Conceptually, the door-to-balloon time may be most important for patients with potentially large infarcts who present early, since they have the most myocardium to salvage.
