Abstract

AIM:

To assess the impact of combined treatment with simvastatin and ezetimibe or treatment with simvastatin only on lipoprotein-associated phospholipase A2 in patients with ischemic heart disease.

METHODS:

One hundred patients with angiographically documented coronary atherosclerosis took part in the investigation. Lp-PLA2 mass and cholesterol fractions were determined at baseline and after 6 months of treatment. Lp-PLA2 mass was determined by enzyme immunoassay method, using two highly specific monoclonal antibodies.

RESULTS:

Combined treatment with ezetimibe and simvastatin led to significantly greater declines in Lp-PLA2 and cholesterol fractions compared with treatment only with simvastatin: Lp-PLA2 decreased by 46 vs 38%, total cholesterol by 35 vs 28%, LDL cholesterol by 50 vs 40%, respectively (p<0.05). Combination therapy with ezetimibe and simvastatin 20 and 40mg/day proved to be as effective as monotherapy with simvastatin 80 mg/day on the effect on Lp-PLA2 mass and cholesterol fractions (p<0.05). Lp-PLA2 correlated positively with total cholesterol (r=0.28) and LDL-C (r=0.33).

CONCLUSIONS:

Combined treatment led to greater reduction of total cholesterol and LDL-C, as well as significantly reduced level of Lp-PLA2 mass. The latter can be considered as target for suppression of inflammation and achievement of stabilization of atherosclerotic plaque.
