What this trial studies

This observational cohort study involves 100 transgender women receiving gender-affirming hormone treatment. Participants will be followed for outcomes related to cardiovascular health at intervals of 1, 3, 5, and 10 years. The study aims to assess the formation of non-calcified and calcified plaques through coronary CT angiograms, evaluate heart function via echocardiograms, and measure various cardiovascular risk markers in blood and urine. The goal is to better understand the long-term cardiovascular effects of hormone therapy in this population.

Why it matters

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

How similar studies have gone: While there have been studies on hormone treatment in transgender individuals, this specific long-term observational approach focusing on cardiovascular outcomes is relatively novel.
