Brief summary
1. Conduct a large-sample, multicenter, superiority, double-blind, randomized controlled clinical trial to verify the efficacy of TJC in reducing the risk of cardiovascular and cerebrovascular events in patients with metabolic syndrome at high cardiovascular and cerebrovascular risk (HCR-MS). 2. Further construct an evaluation system for the long-term cardiovascular and cerebrovascular benefits of traditional Chinese medicine in regulating glucose and lipid metabolism through the evaluative study of the cardiovascular and cerebrovascular benefits of TJC.
Interventions
Intervention Agent: The study employs Tongmai Jiangtang Capsule (TJC), a traditional Chinese medicine compound formulated based on TCM theory. It has the functions of Nourishing Yin, clearing heat and activating blood circulation, and can comprehensively regulate glucose and lipid metabolism as well as improve cardiovascular and cerebrovascular functions. Intervention Population: The study focuses on patients with metabolic syndrome at high cardiovascular and cerebrovascular risk (HCR-MS) who meet the TCM criteria for Qi-deficiency and Blood Stasis syndrome, reflecting personalized and precision intervention. Intervention Design: A long-term study design with 26 weeks of intervention followed by 26 weeks of follow-up is adopted to comprehensively assess the short-term efficacy and long-term cardiovascular benefits of TJC. Control Design: The study employs a double-blind, randomized, placebo-controlled method.
Participants in this Arm will receive a placebo capsule that is identical in appearance, size, color, formulation, weight, taste, and smell to TJC, in addition to standard treatment.
