A Dynamic Evaluation of Chronic Heart Failure Prognosis: the MECKI Score

"At the baseline visit ,CPET-related variables, echocardiographic, ECG, therapy and blood chemistry data will be collected. The baseline CPET will be repeated within 2 weeks. Patients will perform 4 follow up visits at 6, 12, 18 and 24 months after the baseline visit. At every study step, it will be performed:~* Echocardiography (LVEF)~* Blood sample (Na+, MDRD, Hb)~* Maximal ramp protocol CPET (peakVO2, VE/VCO2 slope)"
