Effect of a Mobile Internet Regional Cooperative Rescue System on Reperfusion Efficiency and Prognosis of STEMI Patients

摘要

Objective: To explore the effect of a mobile Internet regional cooperative rescue system on reperfusion efficiency and prognosis of patients with ST segment elevation myocardial infarction (STEMI). Methods: The patients were divided into two groups: the regional transported group (experimental group) and routine transported group (control group) according to whether the first medical contact (FMC) unit was equipped with a regional cooperative rescue system. Every time point during transport process, the time to peak and peak value of cardiac troponin I (cTNI), the rate of heart failure or cardiac death during hospitalization, the value of ejection fractions (EF) measured in 24 h, and indicators of health economics(total hospital charges, days) were observed. Results: The difference of time delay between two groups were all statistically significant P(<0.05); the peak time of cTnl was earlier in experimental group than control group ((14.2 ± 3.4) h vs. (16.3 ± 4.6) h, P < 0.01), the peak value of cTnl was decreased in experimental group compared with the control group ((9.3 ± 2.9) ng/ml vs. (12.3 ± 3.2) ng/ml, P < 0.01); values of EF within 24 h after admission were significantly lower in control group than experimental group (t = 2.37, P < 0.05); in-hospital heart failure rate of experimental group was less than that of the control group 2x(= 4.46, P = 0.03); cardiac mortality rate of experimental group was less than that of the control group, and it was not significant between the two groups (x 2 = 0.19, P = 0.66); total cost in hospital, total hospital stay were significantly decreased in experimental group compared with the control group ((56711 ± 12083) yuan vs. (65847 ± 14691) yuan, P < 0.01; (6.35 ± 3.68)d vs. the day (8.64 ± 5.19)d, P = 0.01). Conclusions: Regional cooperative rescue system could significantly shorten the time delay of patients with STEMI, improve heart function in acute stage and reduce the time and cost in hospital.
