Abstrakt		Patient-reported outcomes such as health-related quality of life (HRQoL) are main treatment goals for heart failure (HF) and therefore endpoints in multinational therapy trials. However, little is known about country-specific differences in HRQoL and in treatment-associated HRQoL improvement. The present work sought to examine those questions. METHODS AND RESULTS: We analysed data from the Cardiac Insufficiency Bisoprolol Study in Elderly (CIBIS-ELD) trial, in which patients from central and south-eastern Europe completed the HRQoL questionnaire SF-36 at baseline and the end of a 12-week beta-blocker up-titration (follow-up). 416 patients from Serbia (mean age 72.21 years, 69% NYHA-class I-II, 27.4% women) and 114 from Germany (mean age 73.64 years, 78.9% NYHA-class I-II, 47.4% women) were included. Controlling for clinical variables, the change in mental HRQoL from baseline to follow-up was modulated by Country: Serbian patients, M baseline = 37.85 vs. M follow-up = 40.99, t(526)%=%5.34, p%<%.001, reported a stronger increase than Germans, M baseline = 37.66 vs. M follow-up = 38.23, t(526)%=%0.68, ns. For physical HRQoL, we observed a main effect of Country, M Serbia = 39.28 vs. M Germany = 35.29, t(526)%=%4.24, p%<%.001. CONCLUSION: We observed significant differences in HF patients from Germany and Serbia and country-specific differences between Serbian and German patients in mean physical HRQoL. Changes in mental HRQoL were modulated by country. Those results may reflect psychological, sociocultural, aetiological differences or regional differences in phenotype prevalence. More importantly, they suggest that future multinational trials should consider such aspects when designing a trial in order to avoid uncertainties aligned to data interpretation and to improve subsequent treatment optimisation.
