Transgender men have a four times higher risk of heart attack than cisgender women, and twice the rate of heart attack than cisgender males. For transgender women, the risk of heart attack is twice the risk as in cisgender women. However, there is no significant difference in risk between transgender women and cisgender males.
Combining fMRI and behavioral data, researchers examined gender identity in cisgender and transgender individuals using a new machine learning algorithm. The AI identified at least nine dimensions of brain-gender variation.
