Racial and Sex Differences in Cardiac Autonomic Function

In this episode of the APS Publications Podcast, featuring an article from AJP–Regulatory, Integrative and Comparative Physiology, authors Ziba Taherzadeh and Claire Kissell discuss the influence of race and sex and Cardiac autonomic function. Their study found that non-Hispanic Black adults living in the United States are more likely to develop cardiovascular disease compared with their non-Hispanic White adult counterparts. These results support that reduced cardiac autonomic function does not manifest early in life among young non-Hispanic Black adults, but rather non-Hispanic Black men had greater spontaneous cardiac baroreflex sensitivity and heart rate variability compared with non-Hispanic White men. No differences were found among women.
