The Scherrer-Crosbie laboratory interest is to further the understanding of heart failure development and progression in animal models and in humans. The interest in subclinical heart failure has led the team to explore two populations of interest, patients with cancer and patients with metabolic abnormalities. Dr. Scherrer-Crosbie is the Director of the Echocardiography Laboratory at the Hospital of the University of Pennsylvania and the Director of the Mouse Echocardiography Core Laboratory in the Cardiovascular Institute. As such, she promotes the use of echocardiography, a crucial tool that allows to link signaling pathways to the organ level, and apply basic research findings to clinical research.

I. Cardiovascular health in patients with cancer

1. Develop noninvasive techniques to identifying cancer patients at high risk of cardiovascular complications.

With the improvement in diagnostic and treatment of cancers, the number of cancer survivors and the length of survival have increased. This leads to an aging population, with increased cardiovascular risk, in particular in patients exposed to cancer treatment-induced cardiotoxicity.

Identifying patients at high risk of cardiovascular events is crucial so that adequate monitoring and potential treatment prevents catastrophic heart failure or other cardiovascular compoications.

We identified sensitive echocardiographic indices of cardiac function and demonstrated their usefulness to predict heart Mousefailure and death in mice treated with anthracyclines. Because this model reflects the typical myocardial damage seen in chemotherapy for breast cancer, we set up a multicenter prospective study assessing similar indices in women with breast cancer. We also studied blood biomarkers to similarly identify patients at high risk.

We are currently studying novel noninvasive indices and markers predicting cardiovascular outcomes and exploring the cardiovascular effects of new treatments.

2. Investigate potential treatments to prevent cardiotoxicity in patients with cancer treated with chemotherapy

Investigators are attempting to decrease chemotherapy-induced cardiotoxicity, in particular anthracyclines-induced cardiotoxicity by preventively treating patients with cardiovascular drugs.

In collaboration with Dr. Neilan at Massachusetts General Hospital in Boston, we are spearheading a NIH-funded multicenter randomized study investigating the effects of statins on anthracyclines-induced cardiotoxicity in patients with Non-Hodgkin lymphoma.


II. Brown Adipose Tissue, Heart Failure and Cardioprotection.

Following a long standing interest in the cardiac effect of metabolic abnormalities, our team  became interested in brown adipose tissue, a tissue that has been detected in adult humans in the last decade, and consumes glucose and lipids to produce heat. We developed an echo-based technique to detect brown adipose tissue and estimate its function.

More recently, we have investigated the relationships between brown adipose tissue and cardiovascular health. We are currently working on several NIH funded projects investigating the relationship between brown adipose tissue and myocardial injury and remodeling.
