Prevalence of deaths related to the circulation system in adult patients interned in hospitals in Porto Alegre/RS

Introduction: Cardiovascular diseases are the leading cause of death in Brazil, accounting for over seven million deaths annually worldwide. These diseases primarily affect elderly individuals, women, and people with lower socioeconomic status. This study aims to determine the prevalence of deaths among hospitalized patients with circulatory system diseases, evaluating their association with age and sex, as well as identifying the most common conditions contributing to hospitalization and mortality. Methods: A retrospective descriptive study was conducted using data from the DATASUS database, analyzing hospitalizations and mortality records in hospitals in Porto Alegre/RS from 2009 to 2019. Descriptive statistics were applied to assess mortality prevalence, length of hospital stay, and predominant diseases. Results: The results indicated that 5.1% of all hospitalized patients with circulatory system diseases died, with an average hospital stay of 7.6 days. The most frequent cause of hospitalization was circulatory diseases affecting the lower limbs, with a mortality rate of 13.2% among these patients, predominantly males. The highest hospitalization rates were observed in patients over 60 years of age. Discussion: Between 2009 and 2019, cardiovascular diseases were responsible for a significant proportion of hospital admissions and deaths, particularly among elderly and male patients. Conclusion: This study provides insights into hospitalization and mortality trends, contributing to the development of targeted public health policies aimed at improving the prevention and management of circulatory system diseases.
