Détection de l'insuffisance cardiaque préclinique, intérêt de l'impédancemétrie

Heart failure (HF) is of major importance, growing constantly. HF elicits a high grade of mortality and quality of life with short life expectation and a lot of rehospitalisation. HF costs a lot and is considered as the first medical expend in the US. The four classes 1 to 4 of the NYHA still apply. The first stages are reversible. It is an essential point to separate systolic HF from diastolic HF; myocardial infarction high blood pressure are the two mains “providers”. A new generation of impedance cardiograph, PhysioFlow, allows early diagnosis of severe pathologies, still reversible, thanks to the analysis of signal abnormalities.
