. Cependant, Matériel et méthode : Entre 2017 et 2019, tous les adultes ayant eu une échocardiographie jugée normale à Amiens et à Lille ont été inclus dans une base de données. Après exclusion des sujets avec des antécédents cardiovasculaires ou des conditions pouvant modifier le Qc, 4064 sujets ont été inclus dans l'e?tude. Nous avons se?pare? la population selon le sexe

, La valeur moyenne du VES indexé à la surface corporelle (VESi) était de 39.8±9ml/m² et était légèrement supérieure chez les hommes (p=0.048). La valeur moyenne de l'index cardiaque (IC) était de 2.9±0,8l/mn/m² sans diffe?rence entre les sexes. Après 30 ans, il n'y avait plus de diffe?rences entre les sexes en termes d'IC quelle que soit la tranche d'âge. Les valeurs correspondant au bas de?bit, Résultats La valeur moyenne de Qc dans la population était de 5,4±1,5 ml/min et celle du volume d'e?jection systolique (VES) était de 73,5±17,9 ml

, Ce travail nous a permis de définir des valeurs normales de VES, VESi, Qc et IC par tranches d'âge et par sexe en ETT. L'IC semble être la variable la moins de?pendante du sexe et de l'âge. Nous proposons ainsi les valeurs seuils de VESi à 27 ml/m2, p.35

, ml/m2 défini antérieurement) et d'IC à 1,9 ml/min/m2 pour de?finir le bas de?bit cardiaque
