Traditional Chinese Medicine Intervention for Ischemic Cardiovascular Disease Comorbid With Diabetes Mellitus: An Efficacy Comparative Study

The population with comorbid ischemic cardiovascular disease (ICD) and diabetes mellitus (DM) has been growing rapidly, characterized by high mortality rates and frequent vascular event recurrence. DM exacerbates ischemic heart disease incidence and significantly elevates mortality in this comorbid population. Polypharmacy in these patients increases risks of adverse drug interactions and imposes substantial healthcare burdens. The pathological mechanisms of comorbidity demonstrate significant alignment with the TCM. Experimental studies indicate that Xintong Oral Liquid can ameliorate myocardial ischemia through multiple mechanisms to improve vascular endothelial function and microvascular dysfunction. This study aims to investigate the long-term effects of TCM intervention in patients with comorbid ICD and DM within 72 hours of symptom onset, and to evaluate whether the TCM treatment approach-centered on Xintong Oral Liquid within an integrated general treatment and syndrome differentiation framework-demonstrates superiority over control therapy in reducing 90-day major adverse cardiovascular and cerebrovascular events (MACCEs).
