Cholesterol screening in an ED-based chest pain unit

To evaluate the prevalence of dyslipidemia in patients who are evaluated in a chest pain evaluation unit (CPEU) a prospective study of all patients admitted to our CPEU from January 1 to December 31, 1999 was conducted. Serum total cholesterol (TC) and high density lipoprotein (HDL) levels were obtained unless prior levels were known or at the discretion of the attending physician. Both TC and HDL were tested in 606 (59%) patients. Abnormal lipid levels were reported in 306 (50%) patients. Of these, 86 had both abnormal TC and HDL. Isolated low HDL levels were found in 60 of the patients and TC alone was abnormal in 160. Of the 246 patients with abnormal TC, 169 (69%) had borderline high levels (200-239mg/dL) and 77 (31%) had high levels (≥240 mg/dL). Our study shows a high prevalence of abnormal lipid levels in patients, as identified by a screening protocol in our CPEU.
