Lack of concordance in classification of coronary heart disease risk: high-risk HDL cholesterol less than 35 mg/dl in subjects with desirable total serum cholesterol, less than 200 mg/dl.
In using National Cholesterol Education Program guidelines (for desirable low risk, a total cholesterol level less than 200 mg/dl, and for high risk, a level of high-density lipoprotein cholesterol (HDLC) less than 35 mg/dl), our specific aim was to examine lack of concordance in classification of coronary heart disease (CHD) risk by HDLC less than 35 mg/dl in subjects with total cholesterol less than 200 and to determine whether lack of concordance increased as group CHD risk increased. We studied four cohorts ranging from putatively low to high CHD risk. These included self-referred subjects in a public urban total cholesterol screening (n = 897), hospitalized patients with depression (n = 144), Cholesterol Center referrals at presumed high CHD risk (n = 1120), and patients having coronary arteriography (n = 145) because of presumed coronary artery disease. Total cholesterol was less than 200 mg/dl in 25% of subjects from the urban sampling, in 54% of hospitalized patients with depression, in 27% of Cholesterol Center referrals, and in 41% of those undergoing cardiac catheterization. In these four cohorts, of subjects with total cholesterol less than 200, 7%, 26%, 25%, and 48%, respectively, had HDLC less than 35 mg/dl. The likelihood of having total cholesterol less than 200 and HDLC less than 35 mg/dl was 1.7% in urban public subjects, 6.8% in Cholesterol Center referrals, 13.9% in depressed patients, and 20% in cardiac catheterization patients.(ABSTRACT TRUNCATED AT 250 WORDS)
