Abstract
BACKGROUND
Despite statins and other medications central to atherosclerotic cardiovascular disease (ASCVD) secondary prevention, stable coronary artery disease (SCAD) patients remain at significant cardiovascular risk, partly due to residual inflammation risk (RIR). This study aims to assess if adding Guanxinning to standard ASCVD therapy further mitigates RIR in SCAD patients.
METHODS
In a prospective, randomized, single-blind endpoint design, 50 patients with SCAD who received ASCVD standardized treatment strategy were randomly assigned to either take Guanxinning tablets (4 tablets, thrice daily) or no Guanxinning tablets and were followed up for an average of 12 weeks. The primary outcomes were changes in inflammation-related indicators, including interleukin-2 (IL-2), IL-4, IL-6, tumor necrosis factor-α (TNF-α), and high sensitivity C-reactive protein (hs-CRP).
RESULTS
Compared with the control group, the intervention group showed significantly greater decreases in the levels of IL-2, IL-6, TNF-α, and hs-CRP (all P < 0.05). However, there was no significant difference in the IL-4 level between the two groups (P > 0.05). Compared with the control group, there were also significant improvements in endothelial function-related indicators (vascular endothelial growth factor (VEGF), nitric oxide (NO), and peroxisome proliferator-activated receptor-γ (PPAR-γ)), blood lipid profile (total cholesterol (Tch), low-density lipoprotein cholesterol (LDL-C)), and chest pain related scores (angina and Traditional Chinese medicine syndrome scores) in the intervention group (all P<0.05). There was no significant difference in the triglyceride (TG) and carotid intima-media thickness between the two groups (P<0.05). Compared to the control group, there was no significant difference in the white blood cell line, liver and kidney function, anemia, and bleeding in the intervention group (all P<0.05).
CONCLUSION
The addition of Guanxinning tablets (4 tablets, thrice daily) to the standard treatment strategy for ASCVD was associated with a reduction in the RIR in patients with SCAD and demonstrated good safety.
