Adjuvant qi-invigorating blood-activating tongmai decoction promotes effect of rosuvastatin on senile diabetes mellitus complicated with atherosclerosis.

OBJECTIVE: This study aimed to explore the efficacy and safety of qi-invigorating blood-activating tongmai decoction combined with rosuvastatin in the treatment of senile type 2 diabetes mellitus (T2DM) complicated with atherosclerosis (AS).

METHODS: The clinical data of 122 elderly patients with T2DM complicated with AS treated in Hospital of Chengdu University of Traditional Chinese Medicine from February 2020 to November 2021 were retrospectively analyzed. Among them, 57 patients treated with rosuvastatin alone were divided into a Monotherapy group, and 65 patients treated with qi-invigorating blood-activating tongmai decoction adjuvant combined with rosuvastatin were divided into a combined group. The two groups were compared in terms of efficacy after treatment, incidence of adverse reactions after 8 weeks of treatment, and carotid plaque indexes, glucose metabolism indexes and lipid metabolism indexes before and after 8 weeks of treatment.

RESULTS: The Combined group showed a notably higher response rate than the Monotherapy group (P<0.05), but the two groups showed no significant difference in the incidence of adverse reactions (P>0.05). After 8 weeks of treatment, the intima-media thickness (IMT), plaque area, fasting blood glucose, glycosylated hemoglobin (HbA1c), total cholesterol (TC), triacylglycerol (TG) and low-density lipoprotein-cholesterol (LDL-C) in the two groups decreased significantly, and high-density lipoprotein-cholesterol (HDL-C) in them increased significantly. Furthermore, the Combined group showed significantly higher levels of IMT, plaque area, fasting blood glucose, HbA1c, TC, TG and LDL-C, and a significantly lower HDL-C level than the Monotherapy group (P<0.05).

CONCLUSION: Qi-invigorating blood-activating tongmai decoction can promote the therapeutic efficacy of rosuvastatin in elderly patients with T2DM complicated with AS.
