The antiatherosclerotic effect of statins has been attributed to their hypo
cholesterolemic action. We therefore evaluated the effect, in vitro, of the
addition of the serum of patients taking fluvastatin on human smooth muscl
e cells in order to ascertain the effect of the drug on cell proliferation
and apoptosis. We found that the addition of serum from patients treated wi
th fluvastatin for 6 days caused a significant reduction in cell proliferat
ion, increased cell apoptosis and reduced the B cell leukemia-2 (bcl-2) con
centration. It is concluded that the induction of apoptosis by statins coul
d be a supplementary mechanism in the prevention of atherosclerotic lesions
in humans. (C) 1999 Elsevier Science B.V. All rights reserved.
