Aim. Cardiac rehabilitation (CR) is an important part of heart failure (HF) treatment. The aim of this paper was to evaluate if thoracic fluid content (TFC) measured by impedance cardiography (ICG) is a useful parameter for predicting the outcome of CR. Methods. Fifty HF patients underwent clinical and noninvasive haemodynamic (TFC) assessments before and after 8-week CR. Results. As a result of CR, the patients' exercise tolerance improved, especially in terms of peak VO 2 (18.7 versus 20.8 mL × kg −1 × min −1 ; = 0.025). TFC was found to identify patients with significantly improved peak VO 2 after CR. "High TFC" patients (TFC > 27.0 kOhm −1 ), compared to those of "low TFC" (TFC < 27.0 kOhm −1 ), were found to have more pronounced increase in peak VO 2 (1.3 versus 3.1 mL × kg −1 × min −1 ; = 0.011) and decrease in TFC (4.0 versus 0.7 kOhm −1 ; < 0.00001). On the other hand, the patients with improved peak VO 2 ( = 32) differed from those with no peak VO 2 improvement in terms of higher baseline TFC values (28.4 versus 25.3 kOhm −1 ; = 0.039) and its significant decrease after CR (2.7 versus 0.2 kOhm −1 ; = 0.012). Conclusions. TFC can be a useful parameter for predicting beneficial effects of CR worth including in the process of patients' qualification for CR.
