Hormonal

Gender-affirming hormone therapy (GHT) with estrogen in transgender females (TGF) is associated with an increased risk of myocardial infarction and ischemic stroke compared to cisgender females, whereas testosterone therapy in transgender males (TGM) does not show consistent evidence of increased cardiovascular or cerebrovascular disease risk.

If you are a transgender woman taking estrogen, be aware that your risk of heart attack and stroke may be higher than that of cisgender women, so regular cardiovascular check-ups are important. If you are a transgender man taking testosterone, current evidence does not show a significantly increased risk of heart or brain vessel disease, though blood pressure and lipids should still be monitored.

ModerateQualifiesMEDIUM confidence
Current research about vascular outcomes in adults receiving hormonal therapy is limited... Existing epidemiological data suggest that the use of estrogens in transgender females confers an increased risk of myocardial infarction and ischemic stroke. Conversely, transgender males receiving testosterone lack any consistent or convincing evidence of increased risk of cardiovascular or cerebrovascular disease.

Why this rating

The paper is a review of observational studies, noting limitations such as lack of large cohort studies, lack of appropriate control populations, and reliance on self-reporting in some cases.
