Sex differences in α-adrenergic support of blood pressure

摘要

We tested whether the inter-individual variability in α-adrenergic support of blood pressure plays a critical role in the sex differences in tonic support of blood pressure by the autonomic nervous system. Blockade of the α-adrenergic receptors was achieved via phentolamine and showed a smaller (P < 0.05) decrease in blood pressure in women compared to men, implying that α-adrenergic support of blood pressure is less in women than in men.
