STANFORD, Calif. Researchers at the Stanford University School of Medicine, in collaboration with BioParadox, Inc., have published data supporting the use of platelet-rich plasma as a promising biologic treatment for myocardial infarction (heart attack).
The findings were published online in Cardiovascular Revascularization Medicine and will be presented at The Sixth International Conference on Cell Therapy for Cardiovascular Disease at Columbia University Medical Center, New York City, on January 20, 2011.
Platelet-rich plasma (PRP) has been identified as a novel biologic treatment for wound healing and sports-related injuries. Studies indicate PRP stimulates cell repair via growth factor release and by attracting reparative cells. Only recently, however, have scientists begun to study PRP's potential in repairing damaged cardiovascular tissue.
Working with colleagues at Stanford University Medical Center, lead author Allan Mishra, MD, a leading PRP researcher, studied the effects of RevaTen PRP (a proprietary formulation of concentrated platelets and white blood cells) on cardiac function after inducing cardiac ischemia (damage to myocardial tissue caused by blood restriction) in mice. The research was conducted under the direction of Robert Robbins, MD, chairman of the department of cardiothoracic surgery at Stanford University.
In this study of 28 mice, researchers induced ischemia by either permanently occluding the left anterior descending artery (Group A) or temporarily ligating it for 45 minutes (Group B). The hearts were then injected with RevaTen PRP or saline control. In order to assess cardiac function after treatment, magnetic resonance images were taken at seven days post-procedure (Group A) and 21 days (Group B). Tissue from all hearts was collected for histopathologic evaluation.
In both groups, mice that received PRP after ischemia had significantly better cardiac function as meas
