Objectives: This study was designed to determine whether implementation of pre-
hospital direct notification to cardiologist reduces door-to-balloon time in patients
with ST-segment elevation myocardial infarction (STEMI).
Background: Primary percutaneous coronary intervention (PCI) is recommended even
if patient is transported from non-PCI-capable hospitals. Transport is associated with
treatment delay.
Methods: We implemented 24-hr hotline system between Emergency Medical
Information Center in our city and cardiologists at our institution to reduce transport
delay and to activate catheterization laboratory (Cath Lab) simultaneously. A total of
229 consecutive patients with STEMI who underwent primary PCI from January 2009
through December 2010 were included for this study. Time intervals, clinical, and
procedural characteristics were compared between patients with or without pre-
hospital notification and activation of Cath Lab.
Results: Pre-hospital notification and activation of Cath Lab was performed in 96
(41.9%) patients and associated with a significantly shorter median door-to-balloon
time (DBT) (54.5 vs. 75.9 min, p<0.001). During "off-duty" hours, this difference was
particularly pronounced (56.9 vs. 86.0 min, p=0.001). Patients with pre-hospital
notification and activation of Cath Lab achieved a significantly higher rate of DBT
less than 90 minutes than patients without notification (89.6 vs. 75.9%, p=0.031).
Conclusions: Pre-hospital direct notification to cardiologist and activation of Cath Lab
reduced DBT significantly and increased the rate of DBT less than 90 minutes
significantly in patients with STEMI when patients were transported from non-PCI-
capable hospitals. These findings suggest that regional organization of STEMI-
receiving center network is needed to ensure quality STEMI care in a community.
