Еxperience of using ECG-telemetry in acute coronary syndrome at the pre-hospital stage

Abstract

Introduction. The current level of digitalization in healthcare allows for remote monitoring of the diagnostic process, including real-time transmission and interpretation of electrocardiograms.
The aim of this study is to scientifically substantiate and evaluate the clinical and preventive effectiveness of remote ECG telemetry in preventing the transformation of acute coronary syndrome into myocardial infarction.
Materials and methods. The study was conducted at medical facilities in the Fergana region and involved 220 patients with acute coronary syndrome. Patients were divided into the main group (n=110, use of ECG-telemetry) and the control group (n=110, standard protocol). The time intervals «symptom-hospitalization», «symptomreperfusion», the frequency of myocardial infarction development and the coefficient of relative risk reduction were estimated.
Results. The use of telemetry reduced the time to detect ischemia from 95±18 to 28±7 min (–70.5%), the time from symptom to hospitalization from 157±22 to 47±9 min (–70.1%), and the time from symptom to reperfusion from 265±35 to 118±21 min (–55.5%) (p<0.001). The frequency of acute coronary syndrome transformation into myocardial infarction decreased from 25% to 3%. The relative risk reduction was 88%.
Conclusion. The implementation of ECG-telemetry significantly increases the effectiveness of early diagnosis and prevention of myocardial infarction and can be recommended for widespread implementation in the structure of the emergency medical care service.
