Arterial stiffness, isolated systolic hypertension, and cardiovascular risk in the elderly.

Isolated systolic hypertension is an important cardiovascular risk factor in the elderly. In addition to systolic blood pressure, pulse pressure, pulse wave velocity, and carotid wave reflections are also strong cardiovascular risk factors in the elderly, as a consequence of the two main determinants of systolic hypertension: increased arterial stiffness and early wave reflections. Taken together, all these findings should help to optimize drug treatment, which has been shown to produce important but thus far insufficient beneficial effects on cardiovascular morbidity and mortality.
