ROCHESTER, Minn. A multinational clinical trial involving Mayo Clinic researchers has found stem cell-based therapy improved quality of life for patients with advanced heart failure.

In the study, patients reported their daily hardship lessened when stem cells optimized for heart repair supplemented the standard of care, and the study further documented lower death and hospitalization rates among those treated with cell therapy.

"In this era of global aging, people live longer, yet are at risk of chronic disease imposing a poor quality of life. Heart failure is an emerging epidemic in need of new healing options," says Andre Terzic, M.D., Ph.D., a Mayo Clinic cardiovascular researcher and lead author of the paper. "The stem cell-based approach in the present study demonstrates sustained benefit on physical and emotional health in response to biotherapy."

Dr. Terzic is the Marriott Family Director, Comprehensive Cardiac Regenerative Medicine for the Center for Regenerative Biotherapeutics.

Approximately 800,000 people in the U.S. suffer heart attacks every year.

The study team recruited 315 patients from 39 hospitals in 10 countries who had advanced heart failure despite receiving standard of care. Mayo Clinic says patients were randomly divided into groups that would receive stem cell therapy versus those who would not. Patients assigned to cell treatment underwent cardiac catheterization. Then, stem cells taken from their own bone marrow and programmed to heal damaged heart tissue were delivered to the heart. Patients assigned not to receive stem cells had cardiac catheterization without cell delivery known as the sham treatment.

"Data from one of the largest cardiovascular cell therapy trials, testing a regenerative technology discovered at Mayo Clinic, indicate benefit in both quantity and quality of life in advanced heart disease," saysSatsuki Yamada, M.D., Ph.D., a Mayo Clinic cardiovascular researcher, and first author on the study. "The benefit of regenerative care has been typically evaluated on the basis of clinician-reported outcomes. What's unique in this study is that it was designed to listen to the patient's experience."

This research is published in Stem Cells Translational Medicine.
