Key Points
- To review the hemodynamic alterations and vascular mechanisms responsible for the disproportionate elevation of systolic blood pressure and pulse pressure in elderly hypertensive patients.
- Narrative pathophysiological analysis evaluating systemic hemodynamics, aortic mechanical properties, and arterial tree geometry in aging individuals with hypertension.
- Hypertension in older adults is characterized by a prominent increase in pulse pressure over mean arterial pressure, driven by a disproportionate rise in systolic relative to diastolic blood pressure.
- Elevated systolic levels result from combined increases in arterial stiffness—predominantly via structural remodeling of the central aorta—and augmented wave reflections caused by increased pulse wave velocity and reflection points closer to the heart.

Arterial stiffness and wave reflections are the primary drivers of disproportionate systolic blood pressure increases in elderly hypertensive patients.
