Introduction: The COVID-19 pandemic led to a reduction in cardiovascular (CVD) hospital admissions in many countries. We aimed to assess the effect of the COVID-19 pandemic on CVD hospitalizations, management, and mortality in Brazil. Methods: Hospitalization data for the years 2020 and 2021 for Brazil and regions were analyzed using the Datasus hospital admission system. We analyzed the number of hospitalizations, the number and proportion of intensive care unit (ICU) utilization, and the number and proportion of in-hospital deaths. The observed data were compared to the average of the previous three years (2017 to 2019). Absolute differences and risk ratios (RR) were calculated, with the RR obtained by dividing the observed values by the expected ones for each period studied. Results: There was a reduction in CVD hospital admissions, with 184,727 (95% CI 157,579 to 211,876) fewer hospitalizations than expected, representing a decrease of 16.2% (RR 0.838; 95% CI 0.836-0.839). There were two valleys of reduction in CVD hospitalizations, the first before the first peak of Covid-19 hospitalizations and the second simultaneous to the second peak of Covid-19 hospitalizations in 2021. There was a 9% decrease in the absolute number of CVD admissions in the ICU (RR 0.910; 95% CI 0.907-0.912), associated with a 4.7% absolute decrease in the number of CVD admissions that resulted in in-hospital deaths (RR 0.953; 95% CI 0.949-0.957). However, there was an 8.6% increase in the proportion of ICU admissions due to CVD (RR 1.086; 95% CI 1.084-1.088) and a significant increase of 14.4% in the proportion of admissions due to CVD that resulted in in-hospital death. Conclusions: Brazil′s data reveal that the Covid-19 pandemic reduced the number of CVD hospitalizations, but with a higher proportion of ICU use and higher in-hospital mortality.
