Objective: To compare the differences in treatment coverage of patients with systemic arterial hypertension and the proportion of patients with controlled AHT, between December 2020 and December 2021 in health facilities that implemented the HEARTS Initiative, and to explore the facilitators and barriers related to information systems in Mexico.

Methods: Descriptive ecological observational study. The results at health facilities that have begun implementing the HEARTS Initiative (n=29) in Chiapas and Sonora were compared, with respect to the variables of treatment coverage and control of AHT, across four periods (semesters) in 2020 and 2021.
