Podsumowanie kontekstu i ogólnych celów projektu

Cardiovascular disease in women is understudied due to underrepresentation in clinical studies. This underrepresentation has led to serious questions around diagnosis and treatment of cardiovascular disease in women as pathophysiology of the disease has different characteristics compared to men.
In this project, we aim to unravel these sex differences and translate female-specific biology to blood diagnostics to improve the diagnoses of heart diseases in women.

Prace wykonane od początku projektu do końca okresu sprawozdawczego oraz najważniejsze dotychczasowe rezultaty

Cardiovascular disease causes 51% of deaths in women and 42% of deaths in men in Europe. Women are contributing mostly to the worrying trend of increases in hospitalizations for coronary artery disease (CAD) at younger ages. Missed and delayed diagnoses in women are more common than in men, as the pathophysiology of CAD in women is different than in men. Men often have atherosclerotic plaque rupture as underlying mechanism for CAD whereas women more often suffer from plaque erosion. Knowledge on mechanisms that explain the sex differences in CAD and plaque erosion is lagging behind. This is due to the underrepresentation of women in clinical trials for CAD and biobank studies.
In the last year, my team has made substantial progress in the elucidation of sex-specific mechanisms driving atherosclerotic disease. We identified important sex differences in gene regulation of atherosclerosis in humans pointing to crucial involvement of smooth muscle cells in atherosclerosis development. Our data suggest that cell phenotypic switching is a dominant feature in female atherosclerosis (Hartman et al. Circulation 2021). Next steps are to understand how these sex differences arise, whether these are driven by sex hormones and their receptors, or sex chromosomes. In addition, we will further identify biomarker profiles that relate to plaque erosion in women.

Innowacyjność oraz oczekiwany potencjalny wpływ (w tym dotychczasowe znaczenie społeczno-gospodarcze i szersze implikacje społeczne projektu)

While this project focusses on atherosclerosis, mulitple other heart disease have sex-specific characteristics as well. Heart failure with preserved ejection fraction, coronary microvascular dysfunction, coronary dissections are all more prevalent in women as compared to men. During this project, we aim to understand if the mechanisms underlying sex differences found in atherosclerosis may also play a role in the other pathologies.
