Effects of hormone replacement therapy on heart function in women with premature ovarian insufficiency

Study of Ventricular Repolarization in Patients With Premature Ovarian Insufficiency and Influence of Estrogen-progestin Replacement Therapy

Not applicable Interventional Assistance Publique - Hôpitaux de Paris · NCT04167033

This study tests how hormone replacement therapy affects heart function in women under 40 with premature ovarian insufficiency to see if it changes their heart rhythm.

What this trial studies

This study investigates how hormone replacement therapy (HRT) affects ventricular repolarization in women diagnosed with premature ovarian insufficiency (POI). It focuses on measuring the corrected QT interval (QTc) on ECG, which can indicate the risk of serious heart arrhythmias. The research aims to understand the relationship between hormonal levels and QTc prolongation, particularly in women under 40 with POI. By comparing these patients to healthy controls, the study seeks to identify potential cardiovascular risks associated with HRT in this population.

Who should consider this trial

Good fit: Ideal candidates for this study are women aged 18 to 40 diagnosed with premature ovarian insufficiency.

Not a fit: Patients with pre-existing cardiac conditions or those currently on hormone replacement therapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could help identify cardiovascular risks in women with premature ovarian insufficiency and optimize hormone replacement therapy to improve their heart health.

How similar studies have performed: Other studies have indicated hormonal influences on QTc prolongation, but this specific approach in the context of POI is relatively novel.
