Connection with estrogen
The keyword here is older. In women, heart attacks and heart disease usually begin at an older age than in men. And there is a reason for estrogen.
Scientists have long known that this female hormone protects women from heart disease. (Interestingly, when researchers experimented with giving estrogen to men, they found that estrogen had no protective effect on men.) When the amount of hormone produced starts to decrease and then stops in menopause, the risk of developing heart disease increases. But the researchers also found that estrogen replacement therapy greatly reduces the risk. According to Trudy L. Bush, Ph.D., associate professor of epidemiology at the Johns Hopkins University Department of Hygiene and Public Health in Baltimore, women who use estrogen replacement therapy are two times less likely to suffer heart attacks compared to those who don't take estrogen.
Experts believe that estrogen helps increase the level of "good" HDL cholesterol (with high density alpha lipoproteins), which "protects" the heart. They found that women taking estrogen had higher levels of “good” cholesterol and lower levels of “bad” LDL cholesterol (with low density alpha-lipoproteins). “It is the high levels of“ bad ”LDL cholesterol that cause plaque clogging of blood vessels and blood vessels in the blood vessels and heart, explains Dr. Bush. But high levels of “good” cholesterol protect the heart and blood vessels from plaque formation. ”
Of course, estrogen replacement therapy also has contraindications. For example, it is thought to increase the risk of certain types of cancer.
