Knowledge of heart disease risk among SHIELD respondents with dyslipidemia.
BACKGROUND
Respondents in the US Study to Help Improve Early evaluation and management of risk factors Leading to Diabetes (SHIELD) reported whether they had a diagnosis of dyslipidemia, were taking prescription dyslipidemia medication, and knew their heart disease risk (low, moderate, high, or do not know). We assessed whether respondents who reported a diagnosis of dyslipidemia with or without lipid-modifying treatment knew their heart disease risk and whether it correlated with National Cholesterol Education Program Adult Treatment Panel (ATP) III risk.


RESULTS
Based on self-report of risk factors, ATP III high risk was defined as diagnosis of heart disease/heart attack, narrow/blocked arteries, stroke, or diabetes; moderate risk included >or=2 risk factors (ie, men aged >45 years, women aged >55 years, hypertension, low high-density lipoprotein cholesterol, current smoking, and family history of CHD); and low risk included <2 risk factors. Of 7629 respondents with dyslipidemia, 35% reported not taking cholesterol medication, and 29% reported not knowing their heart disease risk. For respondents treated for dyslipidemia, 27% reported not knowing their risk, and of the 73% who reported knowing, 24% to 35% reported the same risk level as ATP III risk. For respondents with untreated dyslipidemia, 33% reported not knowing their risk, and of the 67% who reported knowing, 20% to 37% reported the same risk as ATP III risk.


CONCLUSIONS
A large proportion of respondents with dyslipidemia did not know their heart disease risk. Among those who reported knowing their risk level, >60% of respondents did not classify themselves at the same ATP III-defined risk level. There is a gap in understanding and awareness of heart disease risk among respondents with dyslipidemia regardless of treatment status.
