Key result
Hypertension links to lower blood volume in White men, but not Black men.
Why the study?
Differences in blood volume and peripheral renin activity between races in essential hypertension are not well characterized.
Observational (n=65)
No takes yet. Share an insight, caveat, or question.
Racial differences in blood volume and PRA may inform hypertension phenotyping; leaves open effects on contemporary treatment selection.
John A. Mitas (1979) conducted an observational in Hypertension (n=65). Black race vs. White race was evaluated on Blood volume and peripheral renin activity. Black race was associated with different volume-renin relationships; white hypertensive men had lower blood volume than normotensives, while volumes were similar in black men.
