SYSTEMIC ARTERIAL CHANGES AND PULSE PRESSURE: DIFFERENT IMPACT ON RENAL HAEMODYNAMICS IN HYPERTENSIVE PATIENTS.
Objective: Renal resistance index (RRI) is used for kidney disease detection and prognosis, but it also appears a good indicator of systemic vascular changes in hypertensive subjects. Structural atherosclerotic damage, arterial stiffness and pulse pressure may interact each other, and the relationship between intrarenal haemodynamics and systemic vascular alterations has been widely investigated. However, the independent impact of all these parameters on renal haemodynamics and the mechanisms by which they affect renal vasculature remain to be clarified. Design and method: We enrolled 463 hypertensive patients (30–70 years) with normal renal function (group 0; n = 280) and with chronic kidn…
Ageing, lifestyle modifications, and cardiovascular disease in developing countries.
Developing countries face the double menace of still prevalent infectious diseases and increasing cardiovascular disease (CVD) with epidemic proportions in the near future, linked to demographic changes (expansion and ageing), and to urbanisation and lifestyle modifications. It is estimated that the elderly population will increase globally (over 80% during the next 25 years), with a large share of this rise in the developing world because of expanding populations. Increasing longevity prolongs the time exposure to risk factors, resulting in a greater probability of CVD. As a paradox, increased longevity due to improved social and economical conditions associated with lifestyle changes in t…
