Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The purpose of the primary endpoint 1 is the evaluation of the correlation between the end-systolic impedance (ESZ) assessed by the intracardiac impedance measurement and the left ventricular end-systolic volume (LVESV) assessed by echo 2 dimensional biplane Simpson's method. | — |
Secondary
| Measure | Time frame |
|---|---|
| *Identification of a predictive signal pattern of the intracardiac impedance for acute decompensation of heart failure *Evaluate the correlation between intracardiac impedance and the expected 1-year survival period calculated by the Seattle Heart Failure score *Evaluate the correlation between stroke impedance assessed by the intracardiac impedance measurement and stroke volume assessed by echocardiography *Evaluate the correlation between stroke impedance assessed by the intracardiac impedance measurement and the blood concentration of the natriuretic peptide BNP | — |
