TI  - Comparison of official hours versus non-official hours: percutaneous coronary 
      intervention in acute ST-elevation myocardial infarction patients.
PG  - 45-51
AB  - BACKGROUND: Percutaneous coronary intervention (PCI) is now a favorable treatment 
      for acute ST elevation myocardial infarction (STEMI). However, in non-official 
      hours (non-OH), this modality of treatment has a questionable outcome because of 
      the treatment delay. OBJECTIVE: To compare the outcomes of PCI during official 
      hours (OH) with non-OH in acute STEMI patients. MATERIAL AND METHOD: A 
      prospective consecutive registry of PCI in acute ST-elevation MI patients at King 
      Chulalongkorn Memorial Hospital from May 1999 to December 2003 were analyzed. 
      Kaplan Meier survival analysis was used to determine the in-hospital mortality. 
      Multivariate analysis was used to determine the prognostic factors for 
      in-hospital mortality. RESULTS: Two hundred and fifty six consecutive patients 
      (OH-107, non-OH-149) who underwent PCI for acute STEMI were enrolled. Their mean 
      age (61.9 +/- 12.2 vs 60.6 +/- 12.8 y, p = ns), male gender (73.8% vs 73.2%, p = 
      ns), history of diabetes (30.2% vs 33.8%, p = ns), severity of the patients 
      (percent of patients in Killip IV--22.4 vs 21.5, p = ns), ejection fraction (48.7 
      +/- 15.1 vs 45.9 +/- 14.7, p = ns), cardiopulmonary resuscitation prior PCI 
      (15.0% vs 14.2%, p = ns), anterior MI (55.1% vs 51.0%, p = ns) were similar in 
      both groups. Hypertension was slightly less common (39.6% vs 52.7%, p = 0.04) but 
      smoking was more common (62.6% vs 49.0%, p = 0.03) in OH group. Door to balloon 
      time and decision to balloon time were significantly shorter in the OH group than 
      the non-OH group (67.9 +/- 47 vs 119.6 +/- 83 min, p < 0.001 and 60.8 +/- 35 vs 
      98.3 min, p < 0.001). However, the total delayed time was not statistically 
      significantly different (402 +/- 316 vs 424 +/- 215, p = 0.55). Angiographic 
      success rate was achieved in 98.1% for the OH group and 94.7% in the non-OH group 
      (p = ns). In-hospital mortality rate was 10.3% and 10.7% respectively. 
      CONCLUSION: The door to balloon time for PCI in acute STEMI patients in the 
      non-OH group was longer than the OH group; however, the total delayed time was 
      not different. The in-hospital mortality rate was similar.
