Key result
Young, healthy African-American males had significantly lower arterial compliance (5.8 vs. 8.6 mmHg.s; P=0.0017) and baroreflex sensitivity compared to matched non-African-American males.
Why the study?
Do young, healthy African-American males have lower arterial compliance and altered autonomic function compared to non-African-American males?
Population
61 young, healthy males without evidence of hypertension and with a negative family history of hypertension.
Comparison
African-American race vs Age- and gender-matched non-African-American race
Design
Cross-sectional

May signal early ethnic differences in vascular health but should not change practice; leaves open whether these predict future cardiovascular events.
Cross-Sectional (n=61)
Do young, healthy African-American males have lower arterial compliance and altered autonomic function compared to non-African-American males?
Absolute Event Rate: 5.8% vs 8.6%
p-value: p=0.0017
Young, healthy African-American males exhibit lower arterial compliance and altered autonomic balance compared to non-African-American males, which may serve as early markers for future cardiovascular disease.
Zion et al. (2003) conducted a cross-sectional in Healthy (without hypertension) (n=61). African-American race vs. Non-African-American race was evaluated on Arterial compliance (mmHg.s) (p=0.0017). Young, healthy African-American males had significantly lower arterial compliance (5.8 vs. 8.6 mmHg.s; P=0.0017) and baroreflex sensitivity compared to matched non-African-American males.
