More than 250 million women worldwide use hormone-based contraception to be a safe and reliable way to prevent pregnancy. However, according to a new study, they are also associated with the risk of a high stroke and heart attack.

Research from Denmark published in BMJ The prescription has been drawn on records to give more accurate estimates for various products than previous studies. According to scientists, the highest risk estimates were for estrogen -containing products, especially vaginal ring and skin patches.

Researchers emphasize that even if the full risk is low, given the widespread use of these products and the severity of these conditions, physicians should consider these possible risks when determining them.

Earlier, many studies have increased the potential risk of ischemic stroke and heart attack with their use, but the conclusions have been inconsistent. There is also a lack of evidence on the effects of various hormone combinations – as they are taken – pills, transplantation, injections, vaginal rings, or skin patches – and how long.

How was the study done?

For studies, researchers tracked the national prescription record for more than two million Danish women from the age of 15–49 from 1996 to 2021, to find out if the first to use contemporary hormonal contraceptives The risk of stroke and heart attack has increased for the first time compared to the risk of bar stroke and heart attack. They added various types of contraceptives: estrogen-professional pills, vaginal rings, patch, progestin-keval pills, intrauterine equipment, leather transplants and intramuscular injections.

All women who had a history of blood clots, cancer, liver disease, renal disease, polycystic ovary syndrome, endometriosis or infertility treatment, were used, psychiatry medicine, hormonal therapy was used, or from a historctomy Had to pass.

The results showed the most commonly used hormonal contraceptive-the joint estrogen-Propestin’s pill-isschemic stroke and the risk of heart attack were doubled, which means a joint pill for one year and an additional heart attack For every 10,000 women use for every 4,760 women every year for every 4,760 women.

What is an ischemic heart attack?

according to experts, ischemic heart disease References to weakening the heart caused by low blood flow in your heart. Typically, this low blood flow is the result of coronary artery disease, a condition that occurs when your coronary arteries are narrowed.

Ischemic heart disease is also known as cardiac ischemia or ischemic cardiomyopathy.

How to work hormonal contraceptives,

Hormonal contraceptives stopped pregnancy by preventing the release of eggs from the ovaries, thickening the cervical mucus and dilasing the uterine lining. In addition, these contraceptives dilute the uterine lining, which reduces the chances of pregnancy.

Which are Safe contraceptive methods,

According to experts, contraceptives contain only progestin, such as mini-gol, hormonal IUD, and transplantation, usually considered safe for heart health than combination pills. Non-hormonal options such as copper IUD and barrier methods have no heart health risk.

However, being an observation study, it could not find a definite conclusion, and researchers thought that there may be other factors that could increase heart attack and stroke risk that they did not consider. “Although the full risk (of these events) was low, researchers wrote in BMJ,” physicians should include potential risk … in their assessment of profit and risk when determining hormonal contraceptive methods. ”
