Abstract
- Objectives: To evaluate the effect of Yugengtongyu granules on reducing the incidence of adverse cardiovascular events and improving quality of life (QOL) in patients with stable coronary artery disease (SCAD). Methods: A double-blind randomized controlled trial was conducted among SCAD population. One hundred fourteen patients were randomly assigned to experimental group (n = 57) and control group (n = 57) following randomized block design. Combined with the basis of standard treatment of SCAD, the experimental group and control group received Yugengtongyu granules or placebo, respectively, twice daily for 6 months and were followed for another 1 year (18 months in total from enrollment). Major outcomes (any occurrence of cardiovascular death, nonfatal myocardial infarction, or coronary revascularization), minor outcomes (any occurrence of all-cause death, ischemic stroke, readmission due to unstable angina, heart failure, or malignant arrhythmia), and composite outcomes (union of major and minor outcomes) were used to evaluate prognosis; Seattle Angina Questionnaire (SAQ) was applied to evaluate QOL, and levels of low density lipoprotein-cholesterol (LDL-C) and high sensitive C reacting protein (HS-CRP) in serum were tested. Results: The incidence of composite outcomes in the experimental group was significantly lower than that in the control group (3 [5.2%] vs. 11 [19.2%], hazard ratio: 0.273, 95% confidence interval: 0.080–0.926, p = 0.022); major outcomes, minor outcomes, and independent events such as nonfatal myocardial infarction showed lowering trend in experimental group. Experimental group scored significantly higher than control group in four dimensions of SAQ: physical limitation, angina frequency, treatment satisfaction, and disease perception at the third- and sixth-month follow-up; there was no significant difference in serum level of LDL or HS-CRP at all scheduled timepoints. Conclusion: The addition of Yugengtongyu granules based on current standard treatment reduced the incidence of composite outcomes and improved QOL in patients with SCAD. The trial was registered in the Chinese Clinical Trial Registry (ChiCTR-TRC-13004370). [ABSTRACT FROM AUTHOR]
