Abstract: Objective  To explore the effect of preinform template on time of informed consent for primary percutaneous coronary intervention(PPCI) in patients with acute STsegment elevation myocardial infarction(STEMI). Methods  Patients with acute STEMI and treated with PPCI from June 2016 to May 2017 period in 97th hospital of PLA were selected into conventional inform group, and that from June 2017 to May 2018 period into Template inform group. For the latter, standardised preinform template were employed. The catheter rooms were started as soon as informed consents were got and PPCI implemented in the two gropes. Informed consent time and D to B time were contrasted. Results  The basic clinic condition and infraction related arteries were comparable.The informed consent time of Template inform group(n=52) was significantly shortened (［16.1±13.3］ min vs ［26.8±12.5］ min，P<0.001)  and D to B time was reduced  (［79.7±21.5］ min vs ［93.4±22.0］ min，P<0.05)  than that of the conventional inform group(n=68). Conclusion  The preinform template can improves informed consent for PPCI in patients with acute STEMI and shorten time of informed consent and D to B.
