Black participants exhibited post-exercise diastolic BP elevation unlike Caucasians; challenges uniform PEH assumptions and extends race-specific histamine research.
Does combined H1R and H2R blockade affect post-exercise blood pressure and hemodynamic responses differently in young healthy Black versus Caucasian subjects?
Young healthy Black subjects exhibit increased diastolic blood pressure following exercise compared to Caucasians, suggesting differential hemodynamic responses that may contribute to greater cardiovascular disease risk.
