Comparison of reperfusion time of acute STEMI patients by different approaches to hospital treated with PCI under chest pain center mode

ObjectiveTo compare the reperfusion time of patients with acute ST-segment elevation myocardial infarction(STEMI) by different approaches to hospital treated with primary percutaneous coronary intervention(PCI), and to explore the measures to optimize the existing chest pain center.

MethodsA total of 194 STEMI patients undergoing primary PCI were selected and divided into self-admission group(60 cases), 120 call for help group(85 cases) and non-PCI hospital referral group(49 cases).The onset-to-balloon time, symptom-to-first medical contact time, first medical contact-to-balloon(FMC2B) time, qualified rate of FMC2B time, door-to-balloon(D2B) time, qualified rate of D2B time, first medical contact-to-ECG time and so on were observed in there groups.

ResultsThe D2B time in the three groups was below the 90-minute standard, which in 120 call for help group was obviously shorter than that in self-admission group(P < 0.01).The onset-to-balloon time, first medical contact-to-ECG time, FMC2B time in non-PCI hospital referral group were significantly longer than those in self-admission group and 120 call for help group(P < 0.01), and the qualified rate of FMC2B time was significantly lower than that in self-admission group and 120 call for help group(P < 0.01).

ConclusionsPre-hospital delays under the current chest pain center mode, especially non-PCI treatment in primary hospitals, are obvious and need further improvement.
