Early menopause puts women at greater risk of cardiovascular diseases, finds new study

Early menopause puts women at greater risk of suffering a non-fatal cardiac event like heart attack, angina or stroke, finds a new study.

Researchers from The University of Queensland have found that women who reach menopause before the age of 50 have an increased risk of cardiovascular disease. Zhu and colleagues report one of the largest studies to date to investigate the association between age at menopause and onset and timing of incident cardiovascular disease.

School of Public Health senior author Professor Gita Mishra said the results showed early menopause puts women at greater risk of suffering a non-fatal cardiac event like heart attack, angina or stroke.

"Women under 40 who experience premature menopause were nearly twice as likely to have a non-fatal cardiovascular event before the age of 60," Professor Mishra said.

"This is compared to women who reach menopause between the ages of 50 or 51, during what is considered the standard developmental period.

"Women who were aged between 40 and 44 in menopause were 40 percent more likely to suffer from a cardiovascular condition."

Past studies have found an association between early menopause and fatal cardiovascular events.

"The relationship with non-fatal cardiovascular events was unclear until now," she said.

"Smoking, being overweight or obese, and having lower education levels can also strengthen the link between early menopause and a woman's risk of cardiovascular disease."

Insights were gathered from more than 300,000 women in 15 studies around the world using the collaborative databank, InterLACE.

UQ School of Public Health PhD scholar Dongshan Zhu who led the study said that the findings would have important clinical and public health implications.

"Identifying women with early menopause offers a window of opportunity for their doctors to work with them to monitor and actively manage cardiovascular disease risk factors," Mr Zhu said.

"Early clinical diagnosis will help to improve overall cardiovascular health in their postmenopausal years."
