UnlabelledCardiovascular pathology is the leading cause of death in Chile, with an inverse relationship between socioeconomic status and morbidity/ mortality. Currently, there is a lack of information regarding the Macro North Zone of Chile. Our aim is to describe the profile of patients undergoing interventions in a public hospital over a decade.MethodsAn observational ecological study was conducted on patients who underwent interventions from 2012 to 2022. Data were obtained through standardized searches using FONASA codes, including "major" cardiovascular interventions. "Minor" interventions and patients operated on in other centers were excluded. Data collection took place between 2021 and 2023. A database was created and analyzed using descriptive statistics, considering variables such as age range, health insurance, and the number of patients treated per year.ResultsA total of N= 9.075 records were obtained, with 8.908 corresponding to FONASA. The age ranges with the highest number of interventions were 18-60 years (49,8%) and over 60 years (49,6%). Since 2017, more than 50% of interventions have been in individuals over 60 years old. Annual interventions presented an increase in the percentage variation by 117%. Regarding interventions based on health insurance, tier B accounted for 46,7% (4.335) and tier A for 24,2% (2.194). We observed an increase in tier A by 24%.ConclusionWe found that patients are older and belong to lower-income tiers. Additionally, there is a migration towards tier A in recent years and an increase in interventions.
