Abstract
|
|
|
To investigate the potential causes of delays between onset of chest pain and provision of reperfusion therapy. We measured time intervals of prehospital phase and in emergency department in 149 patients with acute myocardial infarction. Data
were
collected by interview with patients for prehospital time delays and time records in emergency department. The results were followings:
Patients who admitted to our hospital prior to 6 hours from chest pain were 519(34%).
Mean prehospital delay time of total patients was 548 minutes. Mean prehospital delay time of direct visit patients was shorter than transported patients(357 vs 595 minutes, p<0.05). In direct visit patients, patient delay time was shorter in
reperfusion group than non-reperfusion group(117 vs 481 minutes, p<0.001). In transported patients, patients delay time and first hospital delay time were shorter in reperfusion group than non-reperfusion group(116 vs 294 minutes in patient delay
time,
70 vs 227 minutes in first hospital delay time, p<0.05 repectively). Transportation time and delay time in emergency department were not different between both groups.
In conclusion, time delays in patients not receiving reperfusion therapy was attributed to prolonged patients delay time and first hospital delay time in prehospital phase.
