Abstract 13132: Heart Disease Mortality Trends During the 21st Century, United States, 2000-2010
Background: Heart disease (HD) remains the leading cause of US deaths. However, knowledge of HD type’s role in these trends is lacking.
Objective: To examine the relative impact HD types have had on overall HD mortality trends among US adults aged 35 years and older from 2000-2010.
Methods: We used the CDC WONDER online database to determine HD mortality rates_based on underlying cause of death. We stratified the results by HD type, age standardized the rates and used SEER’s JoinPoint program to develop log-linear regression models to calculate the average annual percent change (AAPC) in rates. We determined the annual proportion of all HD deaths attributable to each HD type by dividing the number of deaths of each HD type by the number of all HD deaths.
Results: During 2000-2010, 7,102,788 HD deaths were observed (645,708 average deaths per year). HD and coronary heart disease (CHD) mortality declined from 500.8 and 364.7 in 2000 to 347.3 and 221.6 per 100,000 in 2010, with AAPC of -3.8 and -5.1%, respectively. While mortality from most other HD types also declined during this period, albeit at a slower rate than CHD, mortality from hypertensive HD and arrhythmia increased from 18.6 and 13.8 to 20.9 and 15.2 per 100,000, respectively. From 2000 to 2010, the proportion of all HD deaths attributable to CHD declined from 72.8% to 63.8% and increased for all other HD types (figure). In particular, the proportion of deaths from heart failure increased 23.0% (7.9% to 9.7%), hypertensive HD increased 62.0% (3.7% to 6.0%) and arrhythmia increased 60.9% (3.1% to 4.4%).
Conclusion: HD mortality continues to decline during the 21st century. CHD accounts for majority of all HD deaths, although its relative contribution is decreasing. Public health and clinical communities should pay additional attention to mortality for other HD types such as heart failure, hypertensive HD, and arrhythmia and apply evidence-based community and individual-level interventions that prevent and treat these conditions.
