Key result
Hypertension family history in normotensive young men is linked to reduced vascular compliance during fluid loading.
Why the study?
The study tested the hypothesis that normotensive men with positive family histories of hypertension have reduced venous compliance and increased cardiovascular responses to volume expansion and alpha-agonist stimulation.
Do normotensive men with a positive family history of hypertension have reduced venous compliance and altered cardiovascular responses to volume expansion and alpha-agonist stimulation compared to those with a negative family history?
Cross-Sectional
Do normotensive men with a positive family history of hypertension have reduced venous compliance and altered cardiovascular responses to volume expansion and alpha-agonist stimulation compared to those with a negative family history?
Normotensive men with a family history of hypertension exhibit decreased effective vascular compliance, suggesting early pathophysiological changes before the onset of clinical hypertension.

Reduced effective vascular compliance in PFH men is hypothesis-generating; larger prospective studies needed before clinical relevance is established.
Widgren et al. (1992) conducted a cross-sectional in Positive family history of hypertension. Positive family history of hypertension vs. Negative family history of hypertension was evaluated on Effective vascular compliance (change in blood volume: CVP ratio). Normotensive young men with a positive family history of hypertension exhibited decreased effective vascular compliance and altered arterial blood pressure responses to acute fluid volume loading.
