Internações por infarto agudo do miocárdio: O panorama brasileiro frente ao período pandêmico de Covid-19

Abstract

Objective: To analyze the evolution of hospitalizations for Acute Myocardial Infarction (AMI) in Brazil, considering the scenario before and after the Covid-19 pandemic. Methodology: Descriptive and retrospective epidemiological study. Information was obtained from the Notifiable Diseases Information System (SINAN), and the Tabwin program was used to analyze variables and construct percentages. This study analyzed notified cases and deaths related to AMI in SINAN between 2014 and 2024 in Brazil. Results and discussion: The analyzed data indicated a linear increase in the number of hospitalizations related to AMI in Brazil from 2014 to 2024. During this period, there was a predominance of males (60%) and the age group over 50 years (82%), with a greater concentration of cases in the most populous regions. Furthermore, it was identified that changes in the number of cases over the years, as well as the vaccination campaign, are not significant enough to infer factors of change, not even during the COVID-19 period, in which there was an unexpected increase in the number of cases. Final considerations: Finally, it is understood that continuous study of the topic is essential in order to understand which factors – and how – influence the number of hospitalizations due to AMI.
