D2B Time: One Victory in a War with Many Fronts

A new national registry analysis shows that recent reductions in door-to-balloon time did not reduce in-hospital mortality.

Door-to-balloon (D2B) time for primary percutaneous coronary intervention (PCI) in patient with ST-segment-elevation myocardial infarction has become the focus of quality-improvement efforts and national guidelines. These investigators examined national trends in D2B time and in-hospital mortality in 95,007 patients admitted for primary PCI (mean age, 61; 28% women) at 515 sites participating in the CathPCI Registry of the National Cardiovascular Data Registry from July 2005 through June 2009.

The median D2B time significantly decreased from 83 minutes in 2005–2006 to 67 minutes in 2008–2009, but risk-adjusted in-hospital mortality remained virtually unchanged — at about 5% — during the study period. Similarly, mortality did not change over …
