Objective: The objective is to observe the effect of Kuanxiong aerosol(KXA) on angina and the quality of life of patients after percutaneous coronary intervention(PCI). Materials and Methods: Six hundred patients with angina after PCI(AAP) were randomly assigned to an experimental group and a control group(n = 300 in each group) and received basic treatment with KXA or basic treatment(respectively) for 8 weeks. The Seattle Angina Questionnaire(SAQ) and visual analog scale(VAS) scores of the two groups during the screening period and five follow-up periods were compared. Results: A total of 179 patients were included in this interim report, including 85 in the experimental group and 94 in the control group. Among the five-dimensional scores of the SAQ, the improvement in the angina frequency and quality of life scores in the experimental group was better than those in the control group after treatment(P < 0.01), and the difference in scores of the remaining dimensions was not statistically significant(P > 0.01). The difference in VAS scores between the two groups was not statistically significant(P > 0.01). No obvious adverse reactions were observed between the two groups. Conclusions: KXA can reduce the frequency of AAP and improve patients’ quality of life.
