ABSTRACT

Objective:

To investigate the impact of different hospitals on reperfusion time in acute ST-segment elevation myocardial infarction (STEMI) patients from regional cooperative chest pain center (CPC).

Methods:

A total of 364 STEMI patients received percutaneous coronary intervention (PCI) at 18 months before and after CPC establishment were enrolled.Based on hospital levels,the patients were divided into 2 groupsInitial PCI hospital group,n=197 and Initial non-PCI hospital group,n=167.According to hospital visiting time,Initial PCI hospital group was further divided into 2 subgroups as Green channel subgroup,n=91 and CPC subgroup,n=106;Initial non-PCI hospital group was further divided into 2 subgroups as Routine referral subgroup,n=71 and CPC referral subgroup,n=96.Total ischemia time,from onset to first medical contact (S-FMC) time,from S-FMC to balloon dilatation (FMC2B) time,from hospital visit to balloon dilatation (D2B) time were compared among relevant patients;the impact factors for total ischemia time were studied by multivariate regression analysis.

Results:

Compared with Routine referral subgroup,the following parameters were shortened in CPC referral subgrouptotal ischemia time 325 (236,1185) min vs 367 (214,1340) min,P<0.05;FMC2B time 115 (82,227) min vs 149 (94,483) min,P<0.05;D2B time 69 (35,195) min vs 105 (55,260) min,P<0.05.Compared with CPC referral subgroup,the following parameters were further shortened in Initial PCI hospital grouptotal ischemia time 283 (168,873) min vs 325 (236,1185) min,P<0.05;FMC2B time 78 (45,265) min vs 115 (82,227) min,P<0.05.Multivariate linear regression analysis presented that high school or above education (β=-0.117,P=0.047),arrived PCI hospital within 60 min of onset (β=-0.243,P=0.000)and using initial PCI hospital (β=-0.175,P=0.000) were the independent impact factors for total ischemia time in STEMI patients.

Conclusion:

Regional cooperative CPC may shorten FMC2B time by patients' referral;visiting PCI hospital within 60 min of onset was the best way to reduce total isehemia time in STEMI patients.
