Abstract:
Objective To investigate effect of different doses of rosuvastatin on brachial artery endothelium-dependent vasodilation and carotid intima-media thickness in patients with coronary heart disease.Methods 92 patients with coronary heart disease in our hospital were admitted and divided into four groups according to randomly digital method, including 23 cases in control group were treated with lipid nitrate, antiplatelet aggregation, anticoagulant, lowering blood sugar, blood pressure control and other of conventional therapy;23 cases in group A, on the basis of conventional therapy, were treated with rosuvastatin 5 mg/d, orally, once daily;23 cases in group B were treated with rosuvastatin 10 mg/d, orally, once daily based on the conventional therapy;23 cases in group C were treated with rosuvastatin 20 mg/d, orally, once daily based on conventional treatment, each group was treated for 8 weeks.Brachial artery endothelium-dependent vasodilation (FMD) and carotid intima-media thickness (IMT) of patients before and after treatment were collected by color ultrasonic doppler, while observed lipid levels changes of 4 groups.Results Control group was treated for eight weeks, FMD, ITM, blood lipid levels and each index values were not significantly changed, the difference was not statistically significant;After treatment, total cholesterol ( TC) , low-density lipoprotein cholesterol C ( LDL-C) of A, B, C groups were significantly better than that before treatment, the difference was statistically significant (P<0.05), and decrease amplitude with dose of rosuvastatin increased became grearer, but the total cholesterol (TC), high density lipoprotein cholesterol C( HDL-C) there was no significant difference compared with before treatment; Compared with before treatment, ITM of A, B, C groups decreased, and the difference was statistically significant (P<0.05), decrease amplitude with dose of rosuvastatin increased became greater.Conclusion Rosuvastatin can significantly improve brachial artery endothelium-dependent vasodilation and carotid intima-media thickness in patients with coronary heart disease, and there is a clear dose-response relationship, which may be associated with rosuvastatin decrease total cholesterol and low-density lipoprotein cholesterol C in patients with coronary heart disease.It has guide significance to clinical.
