Potential impact
Predicting a woman’s risk of developing a heart condition even before the first symptoms of menopause.
A menopausal woman is four times more likely to develop atherosclerosis. Dr. Catherine Martel and her team are leading the ESTROLY project that focuses on the role the lymphatic system plays in women developing this disease. Their findings could enable health care teams to detect risks at an earlier stage and act preventively, well before the onset of heart disease.

Observation

Observation

Post-menopausal women are more at risk of developing heart conditions

At menopause, a woman’s estrogen levels drop and her risk of atherosclerosis (a hardening of the arteries) increases. And yet the underlying mechanisms of this phenomenon remain largely unknown. 

The lymphatic system — responsible for eliminating excess cholesterol and reducing inflammation in the arteries — could play a key role. In fact, a dysfunctional lymphatic system might be a predictor of heart disease. 

Goal

Identify health risks in women sooner

The ESTROLY project, led by Dr. Catherine Martel, aims to better understand how the lymphatic system is impacted by hormonal changes and what role it plays in the development of atherosclerotic plaque. 

By using cutting-edge imaging technology, her team is assessing the health of lymphatic vessels in women aged 18 to 65. Researchers do so by measuring how often and how well these vessels contract. 

Analyzing both blood and genetic biomarkers could help to predict a woman’s risk of developing a heart condition even before the first symptoms of menopause. 

Impact

Prevent heart disease

Findings from the ESTROLY project could have significant impacts on the cardiovascular health of women. They could allow health care teams to: 

  • Better target at-risk women well before menopause 
  • Use biomarkers to track a person’s cardiovascular health 
  • Inspire the development of new approaches to restore lymphatic function 
  • Develop prevention strategies that take into account women’s biological characteristics 
“Identifying a weakness in the lymphatic system before the first signs of heart disease means providing women with a real opportunity to proactively manage their heart health.”
