OBJECTIVES: The goal of this study was to evaluate the impact of the STAT-MI (ST-Segment Analysis Using Wireless Technology in Acute @entity583 ) network on outcomes in the treatment of @entity1 presenting with @entity583 ( @entity583 ). BACKGROUND: Shortening door-to-balloon (D2B) time remains a national priority for the treatment of @entity583 . We previously reported a fully automated wireless network (STAT-MI) for transmission of electrocardiograms (ECGs) for suspected @entity583 from the field to offsite cardiologists, allowing early triage with shortening of subsequent D2B times. We now report the impact of the STAT-MI wireless network on @entity1188 size, length of hospital stay (LOS), and mortality. METHODS: A fully automated wireless network (STAT-MI) was developed to enable automatic 12-lead ECG transmission and direct communication between emergency medical services personnel and offsite cardiologists that facilitated direct triage of @entity1 to the cardiac catheterization laboratory. Demographic, laboratory, and time interval data of STAT-MI network @entity1 were prospectively collected over a 33-month period and compared with concurrent control @entity1 who presented with @entity583 through non-STAT-MI pathways. RESULTS: From June 2006 through February 2009, 92 @entity1 presented via the STAT-MI network, and 50 @entity1 presented through non-STAT-MI pathways (control group). Baseline clinical and demographic variables were similar in both groups. Overall, compared with control subjects, STAT-MI @entity1 had significantly shorter D2B times (63 [42 to 87] min vs. 119 [96 to 178] min, U = 779.5, p < 0.00004), significantly lower peak troponin I (39.5 [11 to 120.5] ng/ml vs. 87.6 [38.4 to 227] ng/ml, U = 889.5, p = 0.005) and @entity908 phosphokinase-MB (126.1 [37.2 to 280.5] ng/ml vs. 290.3 [102.4 to 484] ng/ml, U = 883, p = 0.001), higher left ventricular ejection fractions (50% [35 to 55] vs. 35% [25 to 52], U = 1,075, p = 0.004), and shorter LOS (3 [2 to 4] days vs. 5.5 [3.5 to 10.5] days, U = 378, p < 0.001). CONCLUSIONS: A fully automated, field-based, wireless network that transmits ECGs automatically to offsite cardiologists for the early evaluation and triage of @entity1 with @entity583 shortens D2B times, reduces @entity1188 size, limits ejection fraction reduction, and shortens LOS.

The STAT-MI (ST-Segment Analysis Using Wireless Technology in Acute XXXX ) trial improves outcomes.
