PP59 Multidimensional Evaluation Of The Reducer Device In Patients With Refractory Angina.

Introduction: Treatments for coronary heart disease patients have had major developments in recent decades, both in the pharmacological and interventional fields, and this has helped to prolong the survival of these patients. However, the growing number of patients who show persistent and disabling symptoms of angina proves that at the same time their quality of life has not been equally improved. Methods: We conducted a multidimensional assessment coherent with health technology assessment methodology on the Coronary Sinus Reducer System (CSRS). CSRS is the latest line of therapy for patients with coronary artery disease who are ineligible for revascularization, demonstrate reversible ischemia, and have refractory angina pectoris (AP) despite optimal standard medical therapy. We performed a literature review in order to gather evidence on efficacy and safety of the device and on the economic and organizational impact of the procedure. In the economic domain we developed a cost-utility model based on a decision tree and a five-year time horizon budget impact model. Results: Several studies in the literature have shown that this therapy is related to an increase in quality of life and an improvement in symptoms of refractory angina. The economic evaluations conducted show how the therapy, despite an increase in the resources absorbed in the first years of implementation, reaches a cost saving profile in the medium term due to positive outcomes, while leading to an increase in the quality of life in patients suffering from refractory angina. Conclusions: The treatment of refractory angina remains a challenge for today's medicine. Patients suffering from this condition are often described as "no option" patients. Thus, despite there is a need of further evidence to establish even more robustly the economic sustainability of the device, especially on its effectiveness in the medium-long term, the device should be taking into account in those patients who could benefit from it in terms of relieving the symptoms of angina and improving their quality of life.
