Background: Stroke and acute myocardial infarction (AMI) are cardiovascular diseases commonly characterized by the development of atheromatous plaques associated with major complications and high mortality rates.Objective: To identify an epidemiological trend in hospitalizations due to stroke and AMI and to analyze the relationship between health programs applied in Primary Health Care, gender and the Federative Unit.Methods: Ecological study with a time series design between 1998 and 2018, collecting data from all federal units in Brazil stratified by, gender and place of residence. There were analyzed Hospitalization Authorizations (AIH) for stroke and MI, consulting the Hospital Admissions System (SIH) of the Informatics Department of the National Health Service with p <0.05.Results: From 1998 to 2018, the rate of hospitalization for AMI increased in Brazil approximately 42.58 events per 100 thousand inhabitants annually (p<0.001), while hospitalizations for stroke declined 32.17 cases (p=0.03). This pattern was observed in both sexes in AMI and stroke. There is also evidence of the effect of the Hiperdia (p<0.001) and Mais Médicos (p=0.001) program in reducing stroke and Hiperdia cases in mitigating the evolution of AMI cases (p = 0.0001). Conclusion:Although these diseases remain as an important cause of death, stroke hospitalization has reduced significantly in the period evaluated. National programs as the Hiperdia and Mais Médicos showed an impact in the acute cases of strokes and AMI.

Resumo O SARS-CoV-2 é o vírus responsável pela pandemia da COVID-19. Essa doença começou a ser melhor entendida devido a outras manifestações clínicas além das respiratórias. Ao longo dos meses de atendimento aos pacientes infectados pelo vírus, foram identificadas alterações clínicas e laboratoriais que incitaram os pesquisadores a discutir sobre o potencial do SARS-CoV-2 no desencadeamento de uma resposta imunológica exacerbada capaz de alterar a homeostase endotelial, através de mecanismos diretos e indiretos. Com esse intuito, foram revisados os possíveis mecanismos que desencadeiam este fenômeno em pacientes portadores de COVID-19. Dessa forma, torna-se importante o entendimento fisiopatológico dos mecanismos imunológicos relacionados à doença para a compreensão do potencial de dano endotelial que a COVID-19 pode promover.
