Abstract MP036: Prevalence of American Heart Association Heart Failure Stages in African-American and White Middle Aged Adults: The CARDIA Study
Background: Symptomatic heart failure is increasingly recognized as a chronic and lethal condition with antecedents, earlier in life, including hypertension, obesity, and diabetes. The American Heart Association (AHA) has developed a four stage heart failure staging classification system. At the year 30 examination (and prior examinations) of the Coronary Artery Risk Determinants in Young Adulthood (CARDIA) data has been collected on a population-based cohort of 48-60 year old black and white men and women.
Methods: Data on demographics and attributes for classification into a heart failure stage were retrieved from the CARDIA database. Participants were then assigned to No Risk, stage A (asymptomatic but with risk factors (hypertension, obesity, diabetes, atherosclerotic disease, metabolic syndrome, cancer), stage B (asymptomatic but prevalent cardiac structural abnormality or prevalent heart disease(prior myocardial infarction, LV hypertrophy, low LV ejection fraction, asymptomatic valve disease), or stage C/D (symptomatic, merged).
Results: The Table shows the prevalence of each heart failure stage by race and gender and for the CARDIA cohort examined in Y30 without missing data. Almost half the cohort is at risk (Stage A) and about a fifth has heart failure associated co-morbidities (Stage B). Only about a fifth of African-Americans have no heart failure risk while about two fifths of whites have no risk, mostly secondary to higher prevalence of obesity and diabetes (p < 0.01). There is a higher prevalence of stage C/D in African-Americans.
Conclusion: Heart failure prevention should begin in young adulthood, particularly in African-Americans.
