Objective To evaluate the economic efficiency of guanxin shutong capsules plus conventional therapy in the treatment of angina pectoris (AP), so as to provide reference for rational allocation of medical medication resources. Methods In this study, Treeage Pro software was used to analyze the cost-effectiveness of guanxin shutong capsules plus conventional therapy versus conventional therapy for AP intervention. The cost parameters were obtained from the Menet database and related literature. At the same time, the economic efficiency of the two treatment plans in short term was evaluated according to the effect parameters (angina efficacy) obtained from a meta-analysis. The intervention time is 4 weeks. Single factor sensitivity analysis (whirlwind plot) and probabilistic sensitivity analysis were used to verify the robustness of the results of this study. Results The basic analysis results showed that the ICER of the two groups was 1078.38 yuan. That is, compared with conventional therapy alone, the conventional therapy combined with guanxin shutong capsules would cost 1078.38 yuan more for each additional effective AP patient. When the patient's personal willingness to pay was higher than 1078.38 yuan, the probability of economic benefit of guanxin shutong capsules plus conventional therapy was better than that of conventional therapy alone. The results of sensitivity analysis verified the robustness of the results of the basic analysis. The clinical efficacy of the guanxin shutong capsules group and the conventional treatment cost of AP had a great impact on the results of the study. When the patients' personal willingness to pay was more than 1050.00 yuan, the intervention plan with higher economic probability was consistent with the results of the basic analysis. Conclusion When the individual willing ness to pay in more than 1050.00 yuan, guanxin shutong capsules puls conventional therapy is more economical for AP patients than conventional therapy alone.
