Abstract 17512: Importance of Pain-to-Door Time and Door-to-Balloon Time in Treating ST-Elevation Myocardial Infarction
Background and Objectives: In treating ST-elevation myocardial infarction (STEMI), early reperfusion therapy is very important. To reduce the ischemic time, pain-to-door time (PTD) might be important as well as door-to-balloon time (DTB). We investigated the relationshiops between PTD / DTB and mortality.
Subjects and Methods: AMI patients admitted to 211 centers via emergency department (ED) were registered in the Korean Health Insurance Review & Assessment Service database in 2009 (male 69.0%, mean age 65.5 years). Among total 15,776 AMI paitents, STEMI patients were 7605. The endpoint was all-cause mortality at 1 year.
Results: About 58.8% of STEMI patients visited ED within 3 hours (Table 1). Compared to patients with PTD < 1 hour, delayed visits were associated with higher short and long-term mortality rates (Table 1 and Figure 1). Regarding DTB, mortality rate increased if DTB > 60 min (Table 1 and Figure 2).
Conclusions: To reduce mortality rates after STEMI, PTD was important as well as DTB. Also, the goal of DTB < 90 min was not enough. We have to do every effort to shorten PTD and DTB.
