## What is ARR (Aldosterone?

La app è stata creata per assistere il medico nello screening dell'iperaldosteronismo primario, una causa comune di ipertensione arteriosa, fornendo il calcolo dell'ARR (Aldosterone-Renin Ratio).
Ciò è possibile partendo dalle diverse unità di misura sia della renina (plasma renin activity, PRA, o concentrazione della renina attiva, DRC) che della concentrazione plasmatica dell'aldosterone (PAC), fornite dai diversi laboratori. Inserendo anche i valori di potassiemia la app fornisce anche una stima della probabilità  individuale del paziente di avere la forma chirurgicamente guaribile di iperaldosteronismo primario, l'aldosteronoma.
Vengono anche fornite alcune informazioni essenziali per un utilizzo appropriato dell'ARR.
