Effects Of Different Admission Methods On Critical Time Points Of STEMI Patients

Objective: In this study,patients with acute ST-segment elevation myocardial infarction(STEMI)were selected as the research subjects to observe whether there were differences between admission mode and critical time points in STEMI patients.In addition,the critical time nodes of different admission modes were studied to find the critical time nodes with the most significant influence on total myocardial ischemia time.The research results can provide certain reference for the improvement and perfection of diagnosis and treatment.Methods: A total of 156 patients with Primary percutaneous coronary intervention(PPCI)and reperfusion Thrombolysis in myocardial infarction(TIMI)grade 3 were enrolled in the study who come from Baise People’s Hospital,those Clinical data of STEMI patients were analyzed.The admission methods of the patients were divided in to three groups:group A,B and C,of which group A was 120 pickup group with 23 cases,group B was self-admission group with 102 cases,and group C was transfer group with 31 cases.SPSS19.0 statistical software was used for door-to-balloon(D-toB),First medical contact to balloon(FMC-to-B),Symptom onset to first medical contact(So-to-FMC),Symptom onset to balloon(So-to-B),First Medical Contact to Electrocardiogram(FMC-to-ECG),time of troponin report,time of canalization lab startup,and general baseline data were analyzed.Results: 1.)Group C had the shortest D-to-B time,and there was no significant diffe rence between group A and group B,group A and group C(P’>0.017),and there was A significant difference between group B and group C(P’<0.017);2.)Group B had the shortest FMC-to-B time,and there was no statistical significance between group A and group B,group A and group C(P’>0.017),but there was statistical significance between group B and group C(P’<0.017).3.)There were no significant differences in SO-to-FMC time,SO-to-B time,FMC-to-ECG time,troponin reporting time and ciliary startup time among the three groups(P>0.05).4.)The SO-to-FMC time in group A,group B and group C was significantly correlated with the SO-to-B time(P<0.05);5.)SO-to-FMC time more than 90 min was associated with the number of deaths in hospital(P<0.05).Conclusion: 1.)This study showes that different admission methods have no effection the SO-to-B,SO-to-FMC,FMC-to-ECG,troponin reporting time and cattle-lab startup time of STEMI patients.2.)This study showes that the D-to-B of patients who are transferred to the hospital is significantly shorter than that of patients who come to the hospital by themselves.3.)This study showe that the FMC-to-B of self-admitte d patients is significantly shorter than that of transferred patients.4.)SO-to-FMC is the key time node of SO-to-B time,shortening SO-to-FMC is our most important task at present.
