title: Factors influencing emergency department arrival time and in-hospital management of patients with acute myocardial infarction.
abstract: Reperfusion of the infarct-related artery in the very first hour ("golden hour") of acute myocardial infarction (AMI) significantly reduces mortality rates. Several factors may delay the initiation of reperfusion therapy (ie, thrombolytic therapy or primary percutaneous transluminal coronary angioplasty [PCTA]), most of which are related to patients. A total of 520 patients with suspected AMI were evaluated in the emergency department of Dokuz Eylül University Hospital between March 1996 and October 1999. After inclusion criteria were applied, the study consisted of 178 patients with a history of AMI. Analyzed data that affected patients' arrival to the hospital were obtained from responses to a questionnaire. The Statistical Package for the Social Sciences (SPSS; SPSS Inc., Chicago, Ill), version 11.0, was used for all statistical analyses. The mean "symptom onset-hospital arrival time" was 188+/-325 min for the entire study group. The median delay was 110 min (approximately 2 h). Only 39 (22%) patients arrived to the hospital within the first hour. The mean time needed for late responders (n=109, 74%) (hospital arrival later than 1 h after symptom onset) to arrive was 245-/+363 min. According to the results of this study, many patients with AMI who may be eligible for reperfusion therapy miss the "golden hour" because of late hospital arrival. Some groups of patients (ie, elderly, women, those with diabetes) were especially late in arriving. To reduce such delays, training programs may be advised to focus on these groups of patients. Arrival times to the hospital during AMI can be greatly improved by efficient public education programs targeted to these groups.
