Abstract/OtherAbstract:
Macrovasculature, microvasculature and the heart determine the structure and function of the circulatory system. Due to the viscoelastic properties of large arteries, the pulsatile pressure and flow that result from intermittent ventricular ejection is smoothed out, so that microvasculature mediates the delivery of nutrients and oxygen to tissues steadily. The disruption of this function, which occurs when microvascular structure develops in response to hypertension, leads to end-organ damage. Microvascular structure is not only the site of vascular resistance, but also the origin of most of the wave reflections generating increased central systolic blood pressure (SBP) in the elderly. Nowadays many data of the literature suggest that hypertension-related damage to the micro and macrovascular system may be manageable through pharmacological agents. Among them, beta-blocking agents and diuretics poorly modify microvascular structure, whereas angiotensin and calcium entry blockade has an opposite effect, thereby reducing central wave reflections and, finally, causing a selective SBP reduction.
