Coping facilitated troponin T increases and hypo-responsivity in the copeptin-HPA-axis during acute mental stress in a Black cohort: The SABPA study

ConclusionsUtilisation of DefS in Blacks provoke vascular hyper-responsiveness and cardiac wall stress (elevated cTnT and NT-proBNP) possibly mediated via the copeptin/vasopressin system. However, a presumably hypo-responsive hypothalamic-pituitary-adrenal-axis during stress exposure could not counteract coronary perfusion deficits via additional copeptin/vasopressin release.
