Principal Research Interest:
Dr. Folts' primary research interest is in mechanisms that increase or decrease in vivo platelet activity and platelet-mediated coronary thrombosis. In the early 1970s, he developed an experimental model to study in vivo thrombus formation in stenosed arteries with endothelial and medial damage. In 1974, he first demonstrated in vivo that aspirin can significantly reduce the incidence of coronary thrombosis. Currently, he is studying the antiplatelet/antioxidant properties of polyphenolic compounds found in red wine, dark beer, fruit juices, and tea.
These compounds appear to be better platelet inhibitors than aspirin. He has published over 125 papers and chapters in books, primarily on topics related to platelet interactions with damaged arterial walls, and food sources that are thought to be protective against the development of atherosclerosis.
His current focus is on functional foods containing polyphenolic compounds called flavonoids, like red wine, purple grape juice, and onions, which have antiplatelet/antioxidant properties, and improve the function of the endothelium allowing for better arterial dilation.
These substances are studied in animal models and human volunteers, with risk factors and with proven coronary artery disease.
