Prevalence of heart disease--United States, 2005

Area of Science:

• Cardiovascular epidemiology
• Public health surveillance
• Health disparities research

Background:

• Heart disease remains the leading cause of death and a major cause of disability in the U.S.
• Significant healthcare expenditures are associated with heart disease, with coronary heart disease costing billions annually.
• Previous data lacked state-specific prevalence for heart disease and detailed information on affected populations.

Purpose of the Study:

• To estimate the prevalence of myocardial infarction (MI) and angina/coronary heart disease (CHD) across all U.S. states, DC, Puerto Rico, and USVI.
• To provide the first state-based prevalence estimates for these specific heart conditions.
• To identify and analyze geographic, racial/ethnic, educational, and sex disparities in heart disease prevalence.

Main Methods:

• Analysis of self-reported data from the 2005 Behavioral Risk Factor Surveillance System (BRFSS).
• Utilized data from all 50 states, the District of Columbia (DC), Puerto Rico, and the U.S. Virgin Islands (USVI).
• Focused on estimating prevalence of myocardial infarction (MI) and angina/coronary heart disease (CHD).

Main Results:

• Substantial geographic disparities in the prevalence of MI and angina/CHD were identified.
• Significant racial/ethnic, educational, and sex disparities were observed in heart disease prevalence.
• The study provides the first state-level prevalence data for MI and angina/CHD.

Conclusions:

• Public health programs should prioritize interventions for disproportionately affected populations.
• Addressing health disparities is crucial to lowering heart disease incidence and achieving Healthy People 2010 goals.
• Targeted public health strategies are necessary to combat inequities in heart disease prevalence.
