Effect Of Age On Isth-Bat Scores And Low Vwf Diagnosis In The Zimmerman Program, Ferdows Atiq, Jorge Di Paola, Et Al.

2020-Current year OA Pubs

An essential component of low von Willebrand factor (VWF)/type 1 von Willebrand disease (VWD) diagnosis is to identify patients with an increased bleeding phenotype, as most individuals with VWF levels in the 30 to 50 IU/dL range do not bleed. The International Society on Thrombosis and Haemostasis-bleeding assessment tool (ISTH-BAT), widely used for assessing bleeding severity, has recently been shown to be age dependent. Although age may also influence ISTH-BAT scores in individuals with VWF levels between 30 and 50 IU/dL, and subsequently affect low VWF diagnosis, this relationship has not been investigated. Therefore, we analyzed 325 participants from the …
