          摘  要  目的  评估维立西呱联合标准治疗方案治疗射血分数降低的心力衰竭(HFrEF)的经济性。方法  基于VICTORIA临床试
          验和相关文献数据构建三状态(包括心力衰竭稳定、心力衰竭住院和死亡状态)Markov模型。模型循环周期为1个月,模拟时限为
          20年,贴现率为5%。采用1倍我国2021年人均国内生产总值(GDP)作为意愿支付(WTP)阈值,对维立西呱联合标准治疗方案治
          疗HFrEF的经济性进行成本-效用分析,以质量调整生命年(QALY)和增量成本-效果比(ICER)作为健康产出指标。采用单因素
          敏感性分析和概率敏感性分析来验证基础分析结果的稳健性。结果  维立西呱联合标准治疗方案相较于标准治疗方案的ICER为
          444 341.95元/QALY,高于本研究的WTP阈值(80 976元/QALY)。单因素敏感性分析结果显示,两组患者的心血管死亡转移概率
          对模型的稳健性影响较大,但对基础分析结果影响不大。概率敏感性分析结果显示,在本研究的WTP阈值下,维立西呱联合标准
          治疗方案更具经济性的概率仅有 2.6%。结论  与标准治疗方案相比,HFrEF 患者使用维立西呱联合标准治疗方案不具有经
          济性。

          Study  on  pharmacoeconomic  evaluation  of  vericiguat  in  the  treatment  of  heart  failure  with  reduced
          ejection fraction

          ABSTRACT   OBJECTIVE  To  evaluate  the  cost-effectiveness  of  vericiguat  combined  with  standard  treatment  in  the  treatment  of

          heart  failure  with  reduced  ejection  fraction (HFrEF).  METHODS  Based  on  the  results  of  the  VICTORIA  trial  and  related
          literature, a three-state (including stable state of heart failure, hospitalized state of heart failure and death state) Markov model was
          constructed. The  cycle  length  was  1  month,  the  time  horizon  was  20  years,  the  discount  rate  was  5%,  and  one  time  China’s  per
          capita  gross  domestic  product (GDP)  in  2021  was  the  willing-to-pay (WTP)  threshold.  Cost-utility  analysis  was  performed  to
          evaluate  the  cost-effectiveness  of  vericiguat  combined  with  standard  treatment  in  the  treatment  of  HFrEF.  The  output  indicators
          included  quality-adjusted  life  year (QALY)  and  incremental  cost-effectiveness  ratio (ICER).  The  robustness  of  the  results  of  the
          basic  analysis  was  verified  by  one-way  sensitivity  analysis  and  probability  sensitivity  analysis.  RESULTS  The  ICER  of  vericiguat
          combined with the standard treatment plan compared to the standard treatment plan alone was 444 341.95 yuan/QALY, which was
          more  than  WTP  of  this  study (80  976  yuan/QALY).  One-way  sensitivity  analyses  showed  that  the  probability  of  cardiovascular
          death in both groups was the main influencing parameter for the robustness of the model, but they had little influence on the results
          of  the  basic  analysis. The  probabilistic  sensitivity  analysis  displayed  that  under  the WTP  threshold  of  this  study,  the  possibility  of
          vericiguat  combined  with  the  standard  treatment  plan  being  more  cost-effective  was  2.6%.  CONCLUSIONS  Compared  with  the
          standard treatment plan, vericiguat combined with the standard treatment plan is not cost-effective in patients with HFrEF.
