Investigating the efficacy of pre-hospital and in-hospital collaborative treatment platform connected with 120-ambulance in the treatment of patients with acute myocardial infarction

Abstract

This study aimed to examine the effectiveness of an integrated pre-hospital and in-hospital collaborative treatment platform connected with 120-ambulance in treating patients with acute myocardial infarction (AMI). 114 patients with AMI who were treated at our hospital within one year of the collaborative treatment model’s implementation were selected as the observation group (January 2022 to December 2022). A random selection of 114 cases treated using the conventional model from January 2020 to December 2020 was chosen as the control group. Control patients received conventional treatment, while observation patients received an integrated pre-hospital and in-hospital treatment. Comparisons of effects were made between the two treatment models for AMI patients. The observation group showed significantly lower first medical contact (FMC) to balloon dilation (FMC-to-B), door-to-balloon (D-to-B), and chest pain onset to admission times than the control group. Across both groups, 99.12% of pre-hospital electrocardiography (ECGs) were completed (113/114), and a significantly higher proportion of patients with Killip class ≥II at immediate admission was observed in the observation group (p < 0.05). Observation group showed significantly higher Left Ventricular End-Systolic Volume (LVESV) and Left Ventricular End-Diastolic Volume (LVEDV) than control group (p < 0.05) one month after surgery. The 6-minute walking distance (6MWD) of the observation group was significantly longer than the control group, and the time taken for the 10-meter walking test was significantly shorter (p < 0.05). A significantly lower incidence rate of hospitalization complications occurred in the observation group (p < 0.05). The integrated pre-hospital and in-hospital treatment platform connected with 120-ambulance showed beneficial outcomes for AMI patients, significantly reducing treatment delay, improving postoperative cardiac function, and reducing postoperative complications, making it worthwhile for promotion in AMI clinical treatment.
