Communication with estrogen

The keyword here is older. In women, heart attacks and heart disease usually begin at a later age than men. And this is the reason why estrogen.
Scientists have long known that the female hormone protects women from heart disease. (Interestingly, when researchers, experimenting, giving estrogen to men, they found that the protective effect of estrogen men does not have.) When the amount of hormone produced starts to decrease, and then stops at menopause, increases the risk of heart disease. But the researchers also found that estrogen replacement therapy greatly reduces the risk. According to Trudy L. Bush, Ph.D., associate professor of epidemiology Hygiene and Public Health of the Faculty of Johns Hopkins University in Baltimore, women who use estrogen replacement therapy were twice as likely to suffer from heart attacks compared with those who do not take estrogen.
Experts believe that estrogen contributes to the level of "good" cholesterol, the HDL (high density lipoprotein), which "protects" the heart. They found that in women taking estrogen, higher levels of "good" cholesterol and lower levels of "bad» LDL-cholesterol (low density with alfalipoproteinami). "It is high levels of" bad »LDL-cholesterol cause the formation in the blood vessels and the heart plaques, clogging blood vessels, says Dr. Bush. But high levels of "good" cholesterol protects the heart and blood vessels from plaque formation. "
Of course, estrogen replacement therapy is also contraindicated. For example, it is assumed that it increases the risk of certain cancers.
