Abstract:
Objective To determine whether field triage would reduce median contact-to-device ( C2D ) time in patients with ST-segment elevation acute myocardial infarction ( STEMI ) . Methods Consecutive patients with STEMI underwent primary percutaneous coronary intervention( PCI) from March 2010 to February 2014 in Shanghai Pudong Gongli Hospital were analyzed. Patients were divided into two groups. A total of 121 patients were admitted by field triage and 101 patients by non-field triage. The primary study point was C2D time and the study points secondary included ( door-to-balloor, D2B) time, peak Troponin I ( TnI) levels, hospital mortality and 30 days follow-up mortality. Results Baseline and procedural characteristics between the two groups were comparable. Comparing to non-field triage group, the C2D time was reduced [(92. 0 ± 56. 0)min vs. (131. 0 ± 61. 0)min,P﹤0. 01]. The D2B time was lower in the field triage group vs. the non-field triage group [(55. 0 ±26. 0)min vs. (96. 0 ±31. 0)min,P﹤0. 01]. The percentage of patients with C2D time less than 90 minutes increased significantly from 85. 1% to 98. 3%( P﹤0. 01 ) in the field triage group. Peak TnI level was significantly reduced in the field triage group [(23. 5 ±22. 0) μg/L vs. (43. 5 ± 39. 0) μg/L,P﹤0. 01]. In-hospital mortality and 30 days follow-up mortality did not significantly differ between the 2 groups (3. 3% and 3. 0%, P=0. 885;3. 3% and 5. 0%, P=0. 544, respectively). Conclusions In STEMI patients, field triage was associated with significantly reduced C2D and D2B times.
