Patients with essential hypertension and normal elastic arteries were younger and had more severe hypertension compared to those with inelastic arteries due to physiologic aging.
Observational
With a new clinical test for the assessment of the elastic quality of the arterial reservoir, evidence has been obtained suggesting that essential hypertension can be separated into 2 distinct clinical types. In one group the elevation of pressure appears to be the consequence of physiologic aging of arteries and in the other hypertension is imposed upon a normal elastic arterial system. Patients in the elastic group were younger and had a more severe type of hypertension than those in the inelastic group.
Conway et al. (1957) conducted an observational in Essential hypertension. Arterial elasticity vs. Inelastic arteries was evaluated on Hypertension severity and age. Patients with essential hypertension and normal elastic arteries were younger and had more severe hypertension compared to those with inelastic arteries due to physiologic aging.
