Asian women have attenuated sympathetic activation but enhanced renal-adrenal responses during pregnancy compared to Caucasian women

摘要

Key points Asian women have a lower prevalence of hypertensive disorders of pregnancy than Caucasian women. This is the first longitudinal study to investigate neural and humoral responses during pregnancy in Asians and Caucasians. The key finding was that Asians had attenuated sympathetic activation but enhanced renal-adrenal responsiveness during pregnancy compared to Caucasians. These results may provide insights into the pathophysiological mechanisms for racial differences in the prevalence of hypertensive disorders during pregnancy.
