Az empagliflozin hatása a szívelégtelenségben szenvedő betegek életminőségére: a nemzetközi Emp-Activity vizsgálat magyar kohorszának eredményei

INTRODUCTION: Heart failure remains one of the leading causes of cardiovascular morbidity and mortality, impairing the quality of life. Based on randomized, controlled clinical trials, SGLT2 inhibitors significantly improve outcomes and reduce symptoms. However, real-world evidence is essential to better assess their effectiveness and safety in everyday clinical practice. OBJECTIVE: To evaluate the effects of empagliflozin therapy on the quality of life and functional status, as well as to assess its safety profile in the Hungarian cohort of the international Emp-Activity study, covering the full spectrum of heart failure. METHOD: This prospective, non-interventional, multicenter, observational study involved symptomatic heart failure patients enrolled from 11 Hungarian centers. A total of 106 patients were enrolled, of whom 101 were assigned to the empagliflozin cohort and 5 to the non-empagliflozin cohort. Patients received empagliflozin as part of routine heart failure therapy and completed the Kansas City Cardiomyopathy Questionnaire (KCCQ-12) at baseline and after 24 weeks. Functional status was assessed using the New York Heart Association (NYHA) classification. RESULTS: 101 patients were enrolled to the empagliflozin cohort (median age 69 years, 28.7% female), primarily in NYHA class II and III. Among them, 57% had HFrEF, 19% HFmrEF, and 22% HFpEF. The most frequent etiology was ischemic heart disease (42%). The most common comorbidities included hypertension (58%), atrial fibrillation (33%), diabetes mellitus (26%), and hyperlipidemia (25%). A significant improvement was observed in the KCCQ-12 overall score (74.3 ± 19.5 vs. 67.1 ± 19.5, p
