Salvia miltiorrhiza: A Potential Red Light to the Development of Cardiovascular Diseases
The aim of this pilot study was to investigate whether the administration of Salvia miltiorrhiza hydrophilic extract (SMHE) reduced the level of soluble vascular cell adhesion molecule-1 (sVCAM-1) and von Willebrand factor (vWF) in diabetic patients with coronary heart disease (CHD). Sixty-two diabetic patients with CHD were recruited and randomly assigned into placebo and treatment groups. Patients were given SMHE for 60 days. Levels of sVCAM-1, vWF and oxidative low density lipoprotein (oxLDL) were determined by using enzyme linked immunosorbent assay (ELISA). The results showed that the levels of VCAM-1 and vWF positively correlated with the level of oxLDL in diabetic patients with CHD. Levels of sVCAM-1 and vWF in serum were reduced significantly in patients receiving SMHE treatment at day 60 in comparison with the baseline. Administration of SMHE also led to a clear decrease in the levels of oxLDL in diabetic patients with CHD. In summary, this study suggests that SMHE has a potential protective effect on the development of diabetic cardiovascular disease.
