摘要
Objective: To explore the effectiveness of Danhong Injection(丹红注射液) on improving microcirculatory injury after percutaneous coronary intervention(PCI) in patients with coronary heart disease(CHD). Methods: A randomized controlled trial was conducted and 90 patients were enrolled. A random sequence was generated using statistical analysis software. Patients with microcirculatory injuries after PCI were randomly divided into 3 groups for treatment(30 subjects in each group): Danhong Injection group: after PCI, Danghong Injections were given with intravenous administration with 40 mL twice a day for a week; statins intensive group: after PCI, atorvastatin calcium tablets were given oral medication with 80 mg once, and then atorvastatin 40 mg daily for 1 week; the control group: after PCI, atorvastatin calcium tablets were given oral medication with 10–20 mg daily for 1 week. The index of microcirculation resistance(IMR) was used to assess microcirculatory injury during PCI. The IMR of the target vessel was reexamined after 1 week of drug treatment. Results: After one week’s drug treatment, IMR was significantly decreased in both statins intensive group and Danhong Injection group compared with the control group(P<0.01), but no difference was found between statins intensive group and Danhong injection group(14.03±2.54 vs. 16.03±5.72 U, P=0.080). Conclusions: The efficacy of Danhong Injection is non-inferior to statin. Early use of Danhong Injection after PCI can effectively improve coronary microcirculation injury after PCI.
