Abstract 9720: Trends In The Prevalence Of Coronary Heart Disease And Congestive Heart Failure Among Adult Population In The U.s.: National Health And Nutrition Examination Survey 2001-2008
Objectives: To evaluate overall trends in the prevalence of coronary heart disease (CHD) and congestive heart failure (CHF) in the U.S. population aged 40 years and older.
Methods: A total of 13866 individuals aged 40 and older participated in the household interview and of these 13,067 were both interviewed and examined in National Health and Nutrition Examination Survey (2001-2008). Demographic variables (age, gender, race/ethnicity, education and health insurance) and risk factors (hypertension, diabetes, high cholesterol and body mass index) were included. Definition of coronary heart disease, congestive heart failure and undiagnosed angina as follows:
Results: The prevalence of coronary heart disease significantly decreased from 10.3% in 2001-2002 to 8.7% in 2007-2008 (P-trend < 0.05) but no changes were observed in CHF. CHD prevalence among women (P-trend = 0.05) and adults with health insurance (P-trend < 0.05) significantly decreased. In adults who had a total cholesterol < 240 mg/dl, CHD prevalence significantly decreased in those without hypertension and in adults who did not have diabetes (p-trend < 0.05 for all groups). The prevalence of angina significantly decreased from 4.8% in 2001-2002 to 3.2% in 2007-2008 (P-trend < 0.05). Meanwhile, the overall prevalence of MI remained unchanged.
Conclusion: The overall prevalence of CHD significantly decreased in the 8 years survey period. The results suggest that the overall decreased prevalence in CHD may have been primarily driven by the decreased prevalence in angina because the prevalence of the other components of CHD did not change over this 8 year interval.
