[Cardiovascular prevention in the elderly: limitations and opportunities]

The world's population is ageing; however, the prolonged life expectancy is barely associated with an increase of healthy aging, and an important part of this demographic shift is a rising susceptibility to development and progressive accumulation of multiple chronic illness, challenging healthcare systems. Aging, therefore, represents the major risk factor for multimorbidity, a milestone for progressive loss of resilience and age-related multisystem homeostatic dysregulation. Cardiovascular risk factors, time and comorbidities play a vicious role in the development of heart disease. Among the other comorbidities, age itself is one of the most important risk factors for the development of cardiovascular disease and the prevalence and incidence of cardiovascular disease in the elderly are significantly increased. Elderly subjects, particularly when frail and with comorbidities, however, are scarcely represented in primary and secondary prevention trial aimed to treat hypercholesterolemia, diabetes mellitus and arterial hypertension. In particular, concerns exist about whether treatment should more or less intensive according to tolerability and risk of interactions; as well as there is uncertainty about therapeutic targets at different ages.This article reviews the relationship between ageing and cardiovascular disease, focusing on several issues regarding cardiovascular prevention in the elderly.
