Abstract


Introduction: Due to the recent implementation of the network system for the care of patients with acute myocardial infarction with ST elevation (AMI CEST) in Mexico, the objective of this study was to compare the mortality of these patients due to cardiovascular events, general mortality, attention times and acute complications in the year prior to the implementation of the system and in the year after it in the Instituto Mexicano del Seguro Social in Guanajuato

Method: Ecological study that compared the databases to evaluate the general mortality, cardiovascular events and complications of patients with AMI CEST in the year before (2016, n = 142) and post (2017, n = 123) implementation of the "infarction code" of patients in the Bajio region, who received Percutaneous Coronary Intervention.

Results: A significant decrease was identified after the beginning of the "infarction code" in the total of major events (27.4% vs. 11.3%, p = 0.001) and in the presence of heart failure (11.2% vs. 0.8%, p = 0.006); but with no specific difference in non-cardiac death, in the presentation of angina, non-fatal arrhythmias, or the need for revascularization between the groups.                   

Discussion or Conclusion: The implementation of the "infarction code" in the Bajio region, Mexico, has beneficial effects in major cardiovascular events and presentation of heart failure.
