Table 3.
Time points assessed in patients with ST elevation myocardial infarction (n = 204)
| Duration (min) | All patients (n = 204) | In-hospital deaths (n = 35) | No deaths (n = 169) | p |
|---|---|---|---|---|
| Prehospital service response time* (n = 77) | 80 (24-177) | 112 (40-198) | 80 (23-178) | 0.79 |
| Transportation time from the place of assistance to the hospital in Montes Claros (n = 77) | 45 (18-84) | 61 (32-145) | 45 (15-71) | 0.47 |
| Total duration of prehospital transportation† (n = 77) | 177 (50-312) | 201 (140-334) | 171 (48-304) | 0.32 |
| Door-to-ECG time‡ (n = 80) | 27 (11-70) | 15 (10-31) | 30 (11-77) | 0.36 |
| Door-to-balloon time (n = 141) | 94 (41-386) | 90 (31-392) | 94 (45-384) | 0.62 |
| Door-to-needle time (n = 4) | 67 (49-73) | 0 | 67 (49-73) | -- |
| Time between pain onset and request for medical service (n = 204) | 486 (248-1657) | 414 (215-1521) | 549 (249-1521) | 0.63 |
| Total ischemia time§ (n =137) | 683 (391-1963) | 587 (346-2283) | 691 (393-1934) | 0.91 |
Prehospital service response time – amount of time between the call and arrival at the place of service;
Total prehospital transport time – amount of time for a response from the prehospital service + time from the site of care to a hospital in Montes Claros;
Door-to-ECG time - for patients who underwent ECG in Montes Claros, time between the ECG and the admission;
Total ischemia time – time from pain onset until medical care + door-to-balloon or door-to-needle time. In patients who remained in clinical treatment (n = 64), the door-to-balloon time, door-to-needle time, and total ischemia time were not evaluated. The p value refers to the comparison between the groups “in-hospital deaths” versus “no deaths”, analyzed with the Mann-Whitney test.
