Current Research

Cardiovascular diseases are the primary cause of mortality in Canadian women and cost the Canadian government more than $20 billion/year. The Women’s Cardiovascular Health lab will perform research with the intent of improving quality of life and standard of care while decreasing the cost of health care. The Women’s Cardiovascular Health lab at York University will determine the mechanisms behind the prevalence and lethality of cardiovascular disease in women and to use this information to find potential avenues of treatment. In particular, the lab will focus on 1) sexually dimorphic autonomic, cardiovascular, and respiratory responses to physiological stressors and the changes in those responses due to sex and/or female sex hormones, 2) determining the mechanism behind the greater propensity of women for orthostatic hypotension (OH) and postural orthostatic tachycardia syndrome (POTS), and 3) researching potential treatment avenues for OH and POTS such as pharmaceuticals (e.g. oral contraceptives/hormone replacement) and exercise interventions. 

Through collaborations with Southlake Regional Health Centre, the lab has also investigated microvascular/endothelial function in male and female cardiac patients (angina, coronary artery disease). We will also be embarking on important research with the Toronto Rumsey Centre investigating cardiac rehabilitation in male and female cardiac patients.
