Door-to-Balloon Time and Mortality among Patients Undergoing Primary PCI

An analysis of national cardiovascular data showed that median door-to-balloon times for primary PCI declined from 83 minutes in 2005 to 67 minutes in 2009, whereas in-hospital mortality remained unchanged during this period. Primary percutaneous coronary intervention (PCI) is currently the preferred treatment for acute ST-segment elevation myocardial infarction. Previous observational studies have shown a strong association between prompt performance of primary PCI, as assessed in terms of the door-to-balloon time (the interval from the patient's arrival at the hospital to inflation of the balloon to restore flow), and reduced mortality. 1 – 3 On the basis of these data, current joint clinical practice guidelines of the American College of Cardiology and the American Heart Association (ACC–AHA) endorse a door-to-balloon time of 90 minutes or less as the goal, giving it a Class I (highest . . .
