Sudano, I; Hess, L; Noll, G; Arnet, D (2011). Persistent dyslipidemia in statin-treated patients: the focus on comprehensive lipid management survey in Swiss patients. Swiss Medical Weekly, 141:w13200.

Abstract

PRINCIPLES:

Statin therapy reduces cardiovascular morbidity and mortality. However, a substantial residual cardiovascular risk can be observed in patients receiving this therapy due to persisting lipid abnormalities as well as to the lack of a systematic global risk-reduction strategy. The objective of the study was to assess the prevalence of dyslipidemia in a cohort of patients living in Switzerland and receiving statin therapy.
METHODS:

This cross-sectional study was conducted by 61 primary care physicians, cardiologists, endocrinologists and internists in Switzerland. Patients were consecutive outpatients≥45 years-old, on statin therapy for at least 3 months with available lipid values. A clinical examination and a recording of the latest lipid values on statin therapy were performed in all patients.
RESULTS:

A total of 473 patients (age 66.3±9.41 years; 61.9% male) were included in the final analysis. Under statin therapy, 40% of the analysed patients had a normal lipid profile, 32.6% presented increased low-density lipoprotein cholesterol (LDL-C) (3.35±0.88 mmol/L), 28.8% low high-density lipoprotein-cholesterol (HDL-C) (0.95±0.18 mmol/L) and 31.1% elevated triglycerides (2.69±1.04 mmol/L). It is of note that the included population was characterised by a high prevalence of cardiovascular risk factors (86.5% patients had 10-year cardiovascular risk>20%). Nevertheless, the lipid lowering therapy was modified in only 15.4% of the patients.
CONCLUSION:

Persistent dyslipidemia is a reality in statin-treated patients and may contribute to their residual cardiovascular risk. Therefore, comprehensive lipid management should be preferred to aggressive LDL-C lowering alone. Moreover, strategies to assess and modify the global cardiovascular risk of patients should be taken into account as an important component of primary and secondary prevention.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
