Gap between guidelines and practice: attainment of treatment targets in patients with primary hypercholesterolemia starting statin therapy. Results of the 4E-Registry (Efficacy Calculation and Measurement of Cardiovascular and Cerebrovascular Events

摘要

BACKGROUND: The aim of this study was to determine the achievement of National Cholesterol Education Program Adult Treatment Panel III goals in patients with primary hypercholesterolemia starting statin therapy in clinical practice. METHODS AND RESULTS: Data were collected by 4401 physicians in private practice on 52 848 patients aged 35-65 years (46.3% women, 53.7% men). 56.1% of patients had no manifested atherosclerosis (primary prevention) among whom 34.9% of men and 0.5% of women had a 10-year coronary heart disease risk over 20% (high-risk) as calculated using the Prospective Cardiovascular Munster study (PROCAM) algorithm. After 6 weeks of statins, only 6.9% of these high-risk men and 4.6% of these high-risk women reached their low-density lipoprotein (LDL) cholesterol target of 2.6 mmol/l or below (100 mg/dl). Even after 9 months, only 8.0% of these men and 6.2% of these women achieved their LDL target. No fewer than 57.3% of treated women had a coronary risk below 10%, and 18.8% of women were already at target before statins were prescribed. Of patients 43.9% had manifest atherosclerosis (secondary prevention). After 6 weeks of therapy, only 12.9% of the women and 16.3% of the men in this secondary prevention group reached LDL target levels of 2.6 mmol/l or below. Even after 9 months, only 21.3% of men and 17.3% of women with manifest atherosclerosis reached target LDL. CONCLUSIONS: Most high-risk patients do not achieve LDL targets. Overtreatment of low-risk groups is also very common.
