Helen E. Collins Laboratory

Investigating Mechanisms Underlying Female Cardiovascular Resilience and Health

The Collins Laboratory

The Collins lab is located at the University of Louisville in the Center for Cardiometabolic Science (Formerly known as the Diabetes and Obesity Center). The Centers webpage is located at www.CenterforCardiometabolicScience.org

Historically, females have been understudied in the context of preclinical and clinical trials contributing to an overall reduced knowledge of basic female cardiovascular biology and also how the female heart responds to physiological and pathological stress. Therefore, the overall mission of the Collins lab is to understand the mechanisms contributing to female cardiovascular health and resilience

Under this larger thematic focus, the Collins lab has several areas of active investigation, they include:
Understanding the mechanisms that contribute to pregnancy-induced cardiac growth and its reversal.

Pathophysiological and etiological mechanisms of peripartum cardiomyopathy and other pregnancy-associated cardiovascular complications.

The response of the female heart to pathological stressors and mechanisms underlying sex-dependent changes in post-infarction remodeling.


Exercise-induced changes in myocardial glucose utilization during periods of active cardiac growth.
