Background: Timing of medical care is a relevant factor for ST-segment elevation myocardial infarction (STEMI) mortality. Objectives: The aim of the present study is to evaluate reperfusion times in STEMI patients participating in a telemedicine-based cardiology care program in the province of La Pampa between August 2018 and December 2021. Methods: This program consists of a protocol for the management of patients with acute coronary syndrome (ACS) in the different locations of the province, with 24-hour remote assistance provided by cardiologists, including both diagnostic support and coordination of on-site thrombolysis. Results: Of a total of 72 STEMI patients evaluated, 44 received thrombolysis as reperfusion therapy, 25 received primary percutaneous coronary intervention, and 3 received thrombolysis followed by rescue percutaneous coronary intervention. Of the 47 subjects who received thrombolysis, only 5 required to be transferred to the referral center for this procedure. Median door-to-needle time was 24 minutes and door-to balloon-time was 105 minutes. Twenty-eight percent of the subjects with primary percutaneous coronary intervention had a door-to-balloon time < 90 minutes and 53.2% of patients who received thrombolysis fulfilled a door-to-needle time < 30 minutes. Conclusions: The implementation of a telemedicine-guided program for decentralized management of STEMI patients was associated with a high percentage of compliance with the goals of implementing fibrinolytic-based reperfusion therapy
