Effects of rosuvastatin on serum lipids and arteriosclerosis in dyslipidemic patients with cerebral infarction.

We investigated the effect of rosuvastatin, 3-hydroxy-3-methylglutaryl-coenzyme A reductase inhibitor, on serum lipids and arteriosclerosis in dyslipidemic patients with cerebral infarction.The subjects were 24 patients with noncardiogenic cerebral infarction complicated by dyslipidemia (low-density lipoprotein cholesterol [LDL-C] ≥ 140 mg/dL). Serum lipids and highly sensitive C-reactive protein (hs-CRP) were measured at the start of the study and at 3 and 12 months after the initiation of oral rosuvastatin (5 mg/day). Cardio-ankle vascular index (CAVI), intima-media thickness (IMT), and plaque score (PS) were also determined at the start of the study and at 12 months.Of the 24 patients admitted, 17 were eligible for statistical analysis. Total cholesterol (TC), LDL-C, and non-high-density lipoprotein cholesterol (non-HDL-C) (mean [standard deviation {SD}], mg/dL) were significantly decreased at 3 months (TC, 149.4 [20.4]; LDL-C, 78.7 [18.6]; non-HDL-C, 94.6 [21.7]) and at 12 months (TC, 154.9 [27.2]; LDL-C, 82.5 [23.3]; non-HDL-C, 100.2 [28.8]) compared with the baseline data (TC, 232.8 [29.7]; LDL-C, 162.2 [21.2]; non-HDL-C, 183.0 [27.7]). The serum hs-CRP level (mean [SD], ng/mL) was 1053.1 [818.8] at baseline, 575.2 [481.8] at 3 months, and 488.1 [357.7] at 12 months. The decrease in this parameter at 12 months was statistically significant. There was a decrease, although not statistically significant, in CAVI (mean [SD]) at 12 months (right [Rt.] 8.7 [.9]; left [Lt.] 8.6 [1.0]), compared with baseline (Rt. 9.1 [1.1]; Lt. 9.0 [1.1]). The max-IMT (mean [SD], mm) was (Rt. 2.11 [.97]; Lt. 2.01 [.75]) at baseline and (Rt. 2.18 [.82]; Lt. 2.06 [.79]) at 12 months of study treatment. The PS (mean [SD], mm) was 8.93 [4.33] at baseline and 9.61 [4.79] at 12 months; neither parameter showed a significant change.Rosuvastatin at 5 mg/day significantly reduced serum levels of TC, LDL-C, non-HDL-C, and hs-CRP in dyslipidemic patients with cerebral infarction. No significant change in CAVI, max-IMT, or PS was noted after the study treatment.
