Significant benefits of new communication technology for time delay management in STEMI patients

In the acute phase of STEMI, the length of the total ischemic interval is the principal factor affecting both short- and long-term mortality. The length of the interval remains a global problem, and in EU countries these figures vary between 160 and 325 min.

The aim of our research was to assess the benefit of the systematic implementation of the new smartphone-based communication technology "STEMI" enabling immediate ECG picture and voice consultation between an EMS crew in the field and a cardiologist in the PCI-center. The transfer of ECG was associated with 92% technical success. 5 Monthly data from 2016 were compared from the reference2 monthly data set in 2015 when the data in the same area was collected in the SLOVAKS registry. The 5-months data from 2016 were compared to the reference group from 2015, when similar 2-months data in the same area in SLOVAKS registry was collected but communication technology "STEMI" technology was not used. In the monitored period in 2016 we recorded a significant decrease in unwanted secondary STEMI transportations (34.32% vs. 12.9%, p<0.001) and a significant reduction in the total ischemic interval (241 min vs. 181 min, p = 0.03). There was no significant decrease in the subinterval of "admission-pPCI" (28min vs. 23 min, p = 0.144).

The systematic use of smartphone-based communication technology "STEMI" enabling remote ECG picture consultation between an EMS crew and a cardiologist in PCI-center had a positive impact on the quality of care for patients with acute STEMI and brought clinical practice closer to the current ESC Guidelines. It significantly decreased the ratio of unwanted secondary transportations and led to a significant reduction in the total ischemic interval.
