Potential Future Burden of Cardiovascular Events Targeted for Prevention by Million Hearts® 2022

The health and economic burden of cardiovascular disease is considerable. Million Hearts® 2022 is a national initiative that supports using evidence-based clinical and community strategies to prevent one million cardiovascular events during 2017–2021. The events targeted for prevention—described as Million Hearts®-preventable events—include the combination of hospitalizations, emergency department visits, and deaths from heart attacks, strokes, heart failure, high blood pressure, and other preventable cardiovascular diseases. Learn more about the Methodology used.

This interactive map shows the Million Hearts®-preventable cardiac event rates (standardized, by age, to the 2010 US Census population) observed during 2016 and the cardiovascular events projected to occur in each state and the District of Columbia (DC) during 2017–2021, if no preventive intervention occurs. Results are presented for all adults aged 18 years or older on the main map, as well as for adults aged 35 to 64 years and can be accessed by clicking on each state. These findings can be used by partners to understand the potential future event burden if no further intervention occurs, and to strengthen their focus on putting into action the prevention strategies outlined by Million Hearts® 2022 [PDF-157K].

At the state level, the Agency for Healthcare Research and Quality’s Healthcare Cost and Utilization Project (HCUP) State Emergency Department Database (SEDD) was used to describe 2016 treat-and-release emergency department visit event rates for 34 states and DC. The HCUP State Inpatient Database (SID) was used to describe 2016 acute, nonfatal hospitalization event rates for 46 states and DC. The National Center for Health Statistics’ National Vital Statistics System Mortality Data were used to describe 2016 mortality rates for all 50 states and DC. Overall mutually exclusive 2016 Million Hearts®-preventable cardiovascular event rates, which equals the sum of the treat-and-release emergency department visits, acute, nonfatal hospitalizations, and death event rates, were available for the 35 jurisdictions with complete data.

For states with complete 2016 data, the overall age-specific mutually exclusive rates (combination of the emergency department visits, hospitalization, and mortality rates) for 2016 were applied to the projected state population estimates during 2017–2021 and summed to determine the expected event totals during 2017–2021. For states with incomplete 2016 data (missing emergency department visit data alone are designated by the single diagonal hatching marks on the map) or in combination with hospitalization data (designated by the cross hatching marks on the map), it was assumed that the proportional relationship across a state’s emergency department visits, hospitalization rates, and mortality rates were the same as the average calculated among states with complete data.

*From all states except Alabama, Alaska, Colorado, Delaware, Idaho, Louisiana, Michigan, Mississippi, New Hampshire, New Mexico, Oklahoma, Oregon, Pennsylvania, Virginia, Washington and West Virginia; emergency department data for Mississippi and Oregon are regularly collected, but 2016 data were not available at time of this report).
