Condition: Premature Ovarian Insufficiency · Sponsor: Assistance Publique - Hôpitaux de Paris
Ventricular repolarization, measured by corrected QT interval (QTc), is influenced by sex hormones. A QTc above 460msec predisposes to the risk of "torsades-de-pointes"(TdP). The investigators have recently shown that estradiol determines an increase in QTc elongation and progesterone shortens it. In addition, high gonadotropin levels (FSH or LH) are associated with QTc prolongation. Hypergonadotropic hypogonadisms (low progesterone and high gonadotropins) are therefore hormonal situations that promote QTc prolongation. Premature ovarian insufficiency (POI) is one of them. Its management is based on the prescription of hormone replacement therapy (HRT). Epidemiological studies have shown that these patients would be at increased risk of cardiovascular mortality. Our team is interested in the effect of this pathological hormonal situation and its HRT on ventricular repolarization in order to define whether this is a population at risk for long QTc.
