What this trial studies

This observational study aims to investigate the impact of cross-sex hormone therapy on cardiovascular function and fat content in the liver and heart among transgender individuals. Participants will undergo two MRI scans, one before starting hormone treatment and another after six months of therapy, to assess changes in their cardiovascular health. Additionally, an oral glucose tolerance test will be conducted at both time points to evaluate metabolic changes. The study seeks to clarify the gender-specific cardiovascular changes associated with high-dose hormone therapy in male-to-female and female-to-male transgender individuals.

Who should consider this trial

Good fit: Ideal candidates for this study are transgender individuals aged 18 and older who are diagnosed with Gender Identity Disorder and are about to begin hormone therapy.

Not a fit: Patients with severe neurological or internal diseases, those under 18 years old, or individuals currently on steroid hormone treatment may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the cardiovascular risks associated with hormone therapy, leading to improved health management for transgender patients.

How similar studies have performed: While there is existing literature on the effects of sex hormones on cardiovascular health, this specific approach focusing on transgender individuals undergoing hormone therapy is relatively novel and has not been extensively tested.
