2000–2020. NVSS is a secure, web-based data management system that collects and disseminates the Nation's official vital statistics. Indicators from this data source have been computed by personnel in CDC's Division for Heart Disease and Stroke Prevention (DHDSP). This was one of the datasets provided by the National Cardiovascular Disease Surveillance System and presented on DHDSP’s Data, Trends, and Maps online tool. This tool was retired in April of 2024 and this dataset will not be updated. Contact dhdsprequests@cdc.gov if you need assistance with data previously included in this dataset. The data are organized by location (national and state) and indicator; NVSS mortality data include CVDs (e.g., heart failure). The data can be viewed by temporal trends and stratified by age group, sex, and race/ethnicity.
