GARCIA-GARCIA¹, Miguel Ángel et al. Cost-effectiveness of cardiac resynchronization therapy in patients with severe heart failure. Insuf. card. [online]. 2015, vol.10, n.1, pp.11-18. ISSN 1852-3862.

Introduction. The therapy of cardiac resynchronization is effective for the treatment of the heart failure, which reduces mortality and number of hospitalizations, and improves quality of life. Material and methods. We evaluate the efficiency of the cardiac resynchronization compared with the best pharmacological therapy by means of an economic evaluation adapted to our sanitary environment. We developed several economic models of Markov. The perspective of the sanitary system is used; the temporary horizon is the duration foreseen of the device, estimated in 7 years. There are included parameters derived from clinical trials and observational studies, with ambulatory and hospitalized patients, and from a meta-analysis. They are patients with symptomatic heart failure with functional class NYHA III-IV, with wide QRS, severe depression of systolic function and sinusal rhythm. We compare cardiac resynchronization added to the best medical treatment, opposite to this medical treatment. Measured variables are years of life and years of life adjusted by quality. Results. The cardiac resynchronization added to the best medical treatment, is a cost- effective treatment, with values of incremental cost - effectiveness of € 6,627 - 8,739 for year of life adjusted to quality of life. Conclusions. The cardiac resynchronization is a cost-effective treatment for these patients. This result changes little on having modified the variables included in the model. The incorporation of devices with implantable cardioverter defibrillator functionality has not been included in our work, but his value probably is greater.
