In the Eplerenone in Mild Patients Hospitalization and Survival Study in Heart Failure (EMPHASIS-HF), aldosterone blockade with eplerenone decreased mortality and hospitalisation in patients with mild symptoms (New York Heart Association class II) and chronic systolic heart failure (HF). The present study evaluated the cost-effectiveness of eplerenone in the treatment of these patients in the UK and Spain.
Results from the EMPHASIS-HF trial were used to develop a discrete-event simulation model estimating lifetime direct costs and effects (life years and quality-adjusted life years (QALYs) gained) of the addition of eplerenone to standard care among patients with chronic systolic HF and mild symptoms. Eplerenone plus standard care compared with standard care alone increased lifetime direct costs per patient by £4284 for the UK and €7358 for Spain, with additional quality-adjusted life expectancy of 1.22 QALYs for the UK and 1.33 QALYs for Spain. Mean lifetime costs were £3520 per QALY in the UK and €5532 per QALY in Spain. Probabilistic sensitivity analysis suggested a 100% likelihood of eplerenone being regarded as cost-effective at a willingness-to-pay threshold of £20 000 per QALY (UK) or €30 000 per QALY (Spain).
By currently accepted standards of value for money, the addition of eplerenone to optimal medical therapy for patients with chronic systolic HF and mild symptoms is likely to be cost-effective.
在依普利酮治疗轻度心力衰竭患者住院和生存研究(EMPHASIS-HF)中,依普利酮进行醛固酮阻断可降低轻度症状(纽约心脏协会II级)和慢性收缩性心力衰竭(HF)患者的死亡率和住院率。本研究评估了依普利酮在英国和西班牙治疗这些患者的成本效益。
EMPHASIS-HF试验的结果用于建立一个离散事件模拟模型,估计在慢性收缩性HF和轻度症状患者中,在标准治疗基础上加用依普利酮的终身直接成本和效果(获得的生命年和质量调整生命年(QALY))。与单纯标准治疗相比,依普利酮加标准治疗使英国每位患者的终身直接成本增加4284英镑,西班牙增加7358欧元,英国的额外质量调整预期寿命为1.22个QALY,西班牙为1.33个QALY。英国每QALY的平均终身成本为3520英镑,西班牙为5532欧元。概率敏感性分析表明,在英国每QALY支付意愿阈值为20000英镑或西班牙为30000欧元的情况下,依普利酮被视为具有成本效益的可能性为100%。
按照目前公认的性价比标准,在慢性收缩性HF和轻度症状患者的最佳药物治疗中加用依普利酮可能具有成本效益。
