Impact of Regional Collaborative Network on the Rescue of Patients with ST-Elevation Myocardial Infarction First...

To assess the effect of a regional collaborative network on the treatment of ST-elevation myocardial infarction (STEMI) patients first admitted to non- percutaneous coronary intervention (PCI) hospitals.

Using data from Kunshan Hospital of Traditional Chinese Medicine's chest pain center database, patients were grouped based on the establishment of the regional collaborative rescue network. Key timepoints and in-hospital complications were analyzed.

A total of 152 ST-elevation myocardial infarction patients were included in the study. Compared to control group, symptom-to-balloon time (S-B), time of first medical contact to balloon and inter-hospital referral time in observation group were significantly shorter [(314.03 ± 209.26) min vs (451.27 ± 290.44) min, P = .001], [(115.32 ± 54.73) min vs (191.67 ± 130.30) min, P = .001], [(55.09 ± 37.23) min vs (112.67 ± 95.90) min, P = .001], but time of symptom to first medical contact were not statistically significant[(210.27±217.07) min vs (239.61 ± 200.92) min, P = .136].The incidence of heart failure and total complications during hospitalization decreased [7 (8.14%) vs 13 (19.70%), P = .037] and [14 (16.28%) vs 24 (36.36%), P = .004]. However no statistically significant difference were observed in rate of death during hospitalization [2 (2.33%) vs 3 (4.55%), P = .450], ventricular fibrillation [2 (2.33%) vs 3 (4.55%), P = .450], left ventricular thrombosis [2 (2.33%) vs 4 (6.06%), P = .244] and recurrent myocardial infarction[1 (1.16%) vs 1 (1.52%), P = .851].

The regional cooperative rescue network notably reduces ischemic and referral times for STEMI patients, lowering the incidence of heart failure during their hospital stay.
