Abstract:
Objective A retrospective analysis were conducted to identify the effect of bypassing the emergency department on 30-days outcomes of patients with acute myocardial infarction undergone primary percutaneous coronary intervention ( PPCI) . Methods From June 2014 to April 2015, 187 patients underwent PPCI in Kunming General Hospital were included. 13 patients were excluded owing to their incomplete follow-up data. The total 174 patients were divided into two groups: the control group (n =59) who did not bypass the emergency department, and the bypass group ( n = 115) who bypassed the emergency department and directly received PPCI. The data of all patients were collected and analyzed. Results There were no significant differences in baseline characteristics and PPCI related data (including percentage of thrombus aspiration catheter used, length or diameter of stents applied between two groups (all P ﹥ 0. 05) . The bypass group had shorter door-to-ballon ( D2B) than the control group [ (67. 7 ± 21. 5) min vs. (89. 4 ± 23. 6) min, P ﹤ 0. 001] . There were no significant differences in 30-days all-cause mortality, re-myocardial infacrtion and target ressel revascularization (TVR) between the two groups (P ﹥ 0. 05) . Total MACEs rate in the bypass group was lower than in the control group (10. 2% vs. 1. 7% , P = 0. 012) . Logistic regression analysis showed that age, diabetes, pain-to-door (PTD) time and CK peak value were the main influencing factors for 30-day MACEs rate of patients receiving PPCI ( P ﹤0. 05) . Conclusions Bypassing the emergency department can shorten D2B time and reduce 30-days MACEs post-PPCI, but reducing the total ischemic time will be more beneficial to patients with acute myocardial infarction.
