Antimullerian hormone (AMH) levels can predict heart disease in middle-aged women, researchers from the University of Pittsburgh have found. The findings were published in the Journal of Clinical Lipidology. Previously, scientists believed that an increased risk of cardiovascular disease may be due to decreased estrogen levels. However, estrogen replacement therapy had no effect. As it turns out, AMH affects women's blood cholesterol levels. AMH is a special substance that is responsible for regulating reproductive function. This hormone is present in both female and male bodies. Antimuller's hormone levels in a woman's body help to assess her readiness to conceive and also predict the onset of menopause. Dr. El Khudari's team analyzed blood samples from 1,440 menopausal women. The scientists determined estrogen and AMH levels, as well as "good" and "bad" cholesterol. As it turned out, high levels of AMH were responsible for lowering "good" cholesterol, while estrogen lowered "bad" cholesterol. During menopause, women lose estrogen and AMH, which raises both "bad" and "good" cholesterol.
