Rosuvastatin Decreases Mean Platelet Volume in Patients With Diabetes Mellitus

Abstract

Statins have multiple effects (also known as pleiotropic effects) on inflammation, plaque stabilization, endothelial function, and hemostasis. We evaluated the effects of rosuvastatin on mean platelet volume (MPV)—a marker for platelet activity—in patients with diabetes mellitus (DM) on rosuvastatin medication. Patients (n = 178) who were to be prescribed high-intensity rosuvastatin were retrospectively enrolled according to their medical records. Baseline and 6-month biochemical tests, automated blood count, cell-volume analysis, and their cardiovascular risk factors were recorded. Rosuvastatin significantly reduced the MPV and the lipid parameters including total cholesterol, triglyceride, and low-density lipoprotein cholesterol (LDL-C). However, there was no correlation between MPV and LDL-C before ( r = −.66; P = .383) and after ( r = −.112; P = .135) rosuvastatin treatment or between ΔMPV and ΔLDL-C after 40 mg rosuvastatin daily therapy ( r = −.155; P = .073). Rosuvastatin significantly decreases the MPV as well as cholesterol levels. The antiplatelet activation properties of high-dose rosuvastatin treatment in patients with DM are not lipid dependent.
