Release Kinetics of Circulating Cardiac Myosin Binding Protein-C Following Cardiac Injury

Researchers have long sought out early biomarkers of cardiac injury, and the new work by Kuster et al takes this search in an exciting new direction. Listen as Associate Editor Merry Lindsey (University of Mississippi Medical Center) interviews lead author Sakthivel Sadayappan (Loyola University Chicago) and expert Ying Ge (University of Wisconsin) about the recent discovery that cardiac muscle-specific myosin binding protein-C is an ultra-early biomarker of myocardial infarction. Will it be feasible to apply detection of myosin binging protein-C to a multi-marker regime, particularly in concert with cardiac troponins, in a clinical setting? Listen and learn.

Sex Differences in Forearm Vasoconstrictor Response to Voluntary Apnea

Is there a difference in how men and women respond to apnea? Yes, according to the recent work by Patel et al published as part of a special call for papers on “Sex and Gender Differences in Cardiovascular Physiology” in AJP-Heart and Circ. Listen as Guest Editor Virginia Miller leads an engaging conversation with lead author Matthew Muller (Penn State Hershey Heart and Vascular Institute) and expert Nina Stachenfeld (The John B. Pierce Laboratory) about the sex differences noted between young men and young women in response to a sympathetic stressor, as well as the roles of aging and reproductive hormones in the noted sex differences.
