Registry studies have suggested improvements in door-to-balloon times, but a national assessment of the trends in door-to-balloon times is lacking. Moreover, we do not know whether improvements in door-to-balloon times were shared equally among patient and hospital groups.This analysis includes all patients reported by hospitals to the Centers for MedicareMedicaid Services for inclusion in the time to percutaneous coronary intervention (acute myocardial infarction-8) inpatient measure from January 1, 2005, through September 30, 2010. For each calendar year, we summarized the characteristics of patients reported for the measure, including the number and percentage in each group, the median time to primary percutaneous coronary intervention, and the percentage with time to primary percutaneous coronary intervention within 75 minutes and within 90 minutes. Door-to-balloon time declined from a median of 96 minutes in the year ending December 31, 2005, to a median of 64 minutes in the 3 quarters ending September 30, 2010. There were corresponding increases in the percentage of patients who had times90 minutes (44.2% to 91.4%) and75 minutes (27.3% to 70.4%). The declines in median times were greatest among groups that had the highest median times during the first period: patients75 years of age (median decline, 38 minutes), women (35 minutes), and blacks (42 minutes).National progress has been achieved in the timeliness of treatment of patients with ST-segment-elevation myocardial infarction who undergo primary percutaneous coronary intervention.
