Why are in utero conditions so critical to cardiovascular health after birth? Listen as Associate Editor Ronglih Liao interviews lead author Loren Wold (Ohio State University) and expert Anne Knowlton (University of California, Davis) about the latest insightful work by Velten et al, which tests a “two-hit” hypothesis mouse model—inflammation followed by hyperoxia—to analyze how cardiac function is altered very early in life. Is Wold’s innovative work bringing the 18th century biologist Lamarck’s theory of inheritance of acquired characteristics front and center in 21st century cardiovascular physiology? Listen and find out.

Is AMP kinase activation a potential therapy for patients with peripheral artery disease? Listen as Editor in Chief Irving Zucker interviews lead author Todd Kinsella (Rigel Pharmaceuticals, Inc.) and expert Michael Massett (Texas A & M University) about the interesting new work by Baltgalvis et al. In the quest to improve exercise intolerance that plagues the millions of patients suffering from peripheral artery disease, Kinsella and colleagues developed and tested a series of indirect AMPK activators for beneficial exercise adaptation in a mouse model of aging, inactivity, and obesity. Did Kinsella and colleagues find any effect of AMPK activators on the microvascular and muscle dysfunction associated with intermittent claudication? Listen and find out.
