Expert opinion of the Heart Failure Working Group of the Polish Cardiac Society on the use of dapagliflozin in the treatment of heart failure with reduced ejection fraction.

Heart failure (HF) is a global health problem inherent in an aging population with coexisting cardiovascular diseases. Based on data from the Polish National Health Fund (Polish, Narodowy Fundusz Zdrowia), approximately 1.2 million people in Poland currently suffer from HF, and 140 000 of them die annually. Recently, Poland was ranked fifth among the European Union countries regarding the number of patients with diagnosed HF and first in terms of the number of HF hospitalizations (547 per 100 000 population) among 34 countries associated in the Organization for Economic Cooperation and Development. In recent years, a significant progress has been made in the diagnosis and treatment of HF with reduced left ventricular ejection fraction (HFrEF), which has resulted in a reduction in cardiovascular and total mortality. Despite these advantages, 5-year survival in the course of HF is still worse than that observed in some types of cancer, both in the populations of men and women. Hence, the search for drugs improving the prognosis in this group of patients is still ongoing. Sodium-glucose cotransporter 2 inhibitors represent a new group of drugs that will undoubtedly be a milestone in the treatment of patients with HFrEF. This expert opinion covers the history of dapagliflozin, which, from a drug dedicated to the treatment of type 2 diabetes, has become one of the most effective drugs improving prognosis and quality of life as well as reducing the number of hospitalizations in patients with HF. This document presents the opinion from the experts of the Heart Failure Working Group of the Polish Cardiac Society on the most relevant studies on dapagliflozin and indications for its use.
