Key result
African blacks and Andean Hispanics had higher central augmentation index values than British whites, whereas American Indians had lower values (all P<0.0001).
Why the study?
Are there ethnic differences in arterial wave reflections (augmentation index) among adults?
Observational (n=10,550)
Yes
Are there ethnic differences in arterial wave reflections (augmentation index) among adults?
p-value: p=<0.0001
Marked ethnic differences exist in arterial augmentation index, highlighting the need for ethnic-specific normative data when assessing hemodynamic profiles and hypertensive organ damage risk.
No takes yet. Share an insight, caveat, or question.
Ethnic differences in wave reflections may affect central BP assessment; leaves open their role in risk stratification.
Chirinos et al. (2011) conducted an observational in General population (n=10,550). Ethnicity (African blacks, Andean Hispanics, American Indians, Chinese) vs. British whites was evaluated on Central (aortic) augmentation index (p=<0.0001). African blacks and Andean Hispanics had higher central augmentation index values than British whites, whereas American Indians had lower values (all P<0.0001).
