Ambulatory blood pressure monitoring in the elderly: features and perspectives.
Aging leads to a multitude of changes in the cardiovascular system that include a rise in blood pressure. Age-related changes in blood pressure are mainly attributable to an increase in systolic blood pressure, generally associated with a slight decrease diastolic blood pressure. This leads to a widening in pulse pressure. Ambulatory blood pressure monitoring is a useful tool to understand these processes and to refine cardiovascular risk assessment. In the light of emerging data in this area, we reviewed the main features of ambulatory blood pressure in elderly and discussed the evidence showing that ambulatory blood pressure is superior to clinic blood pressure to reflect the true pattern of blood pressure over time. Furthermore, we discussed the role of weight control obtained by fitness programs to prevent an excessive rise in blood pressure with age. A thorough understanding of these concepts is of paramount importance and has therapeutic implications in the growing population of elderly subjects with increased blood pressure.
