IRCT20171210037814N1 IRCT 2018-03-13 Qazvin University of Medical Sciences Effect of Code STEMI on "Door to balloon time" - The effect of activation and implementation of the Code STEMI on "Door to balloon time" in patients with myocardial infarction with ST-segment elevation 2017-11-22 anticipated 50 Complete https://irct.ir/trial/29245 interventional Randomization: N/A, Blinding: Not blinded, Placebo: Not used, Assignment: Parallel, Purpose: Health service research, Other design features: The study has two groups of patients with acute myocardial infarction, which, according to the time of referral to the hospital (before or after the start of the STEMI code), fall into one of the control or intervention groups. N/A Acute myocardial infarction. Intervention 1: Control group: The control group is a patient who has been diagnosed with acute myocardial infarction with ST segment elevation before applying the "STEMI code". and transferring them to "cath lab", using the traditional hospital method. Intervention 2: Intervention group:The intervention group includes patients with acute myocardial infarction, which occurs at a time when the STEMI code is launched. These patients are transmitted to the "Cath lab", by members of the STEMI code (with specific job descriptions). No - There is not a plan to make this available Justification or reason for not sharing IPD is Given the multiple variables measured, and given that the data ultimately result in several articles, I do not plan to publish it.
