May guide interpretation of hypertensive vascular changes; leaves open targeted interventions for remodeling.

To examine the physiological mechanisms governing blood vessel development and structural adaptations in response to altered blood flow and pressure.
Narrative synthesis of hemodynamic influences on vessel caliber and wall composition.
Evaluation of cellular responses distinguishing true cell proliferation from structural remodeling in essential hypertension.
Increased blood flow acts as a potent stimulus for vascular growth, expanding the internal lumen diameter.
Elevated intravascular pressure increases the media:lumen ratio via cellular rearrangement (remodeling) rather than proliferation in human essential hypertension.
Physical hemodynamic forces direct vascular architecture, a process hypothesized to involve activation of proto-oncogenes.

Michael J. Mulvany (1992) studied this question.
