Background:

Mobile phone transmission of electrocardiogram photos would reduce time to reperfusion in ST-segment elevation acute myocardial infarction.

Objective:

The aim of this study was to evaluate the efficacy of mobile phone technology as a strategy to shorten times to reperfusion.

Methods:

A quasi-experimental, multicenter study, including patients from the Greater San Miguel de Tucumán, was carried out from August 2017 to April 2018. The strategy consisted in the transmission of electrocardiogram photos by WhatsApp, for the early activation of the infarction protocol. Delay times and impact on the quality of care were assessed.

Results:

A total of 105 patients were analyzed. A significant reduction of the time to diagnosis was observed in the mobile health group [30 min (10-90) vs. 10 min (5-15); <p=0.0001] and in the door-to-balloon time [166 min (135-210) vs. 132 min (80-150); p=0.019].

Conclusions:

The mobile health strategy improved the diagnosis and the door-to-balloon times, though they are still suboptimal.
