The Drug Burden Index (DBI) is associated with poorer physical function in stable, community-dwelling, older people. The authors speculated that a higher DBI is associated with reduced physical function (Barthel Index, primary outcome) and predicts adverse outcomes (length of stay, in-hospital mortality, secondary outcomes) in frail, acutely ill, older(More)
The ageing process is associated with important changes in the responses of the cardiovascular system to pharmacological stimuli. They are not limited to the arterial system, involved in the modulation of cardiac afterload and vascular resistance, but they also involve the low-resistance capacitance venous system and the heart. The main changes include loss(More)
Advancing age is characterized by impairment in the function of the many regulatory processes that provide functional integration between cells and organs. Therefore, there may be a failure to maintain homeostasis under conditions of physiological stress. The reduced homeostatic ability affects different regulatory systems in different subjects, thus(More)
An increasing number of elderly patients are exposed to cardiovascular drugs for the treatment of acute and/or chronic conditions. This is a result of the progressive aging of the population, a common feature in most industrialised countries, and an improvement in primary and secondary cardiovascular prevention strategies with increased survival rates.(More)
AIMS We studied the association between either non-selective NSAIDs (ns-NSAIDs), selective COX-2 inhibitors, or any NSAID and risk of incident myocardial infarction (MI) and heart failure (HF), and all-cause mortality in elderly subjects. METHODS We conducted a retrospective nested case-control study on Australian veterans using nationwide hospital(More)
OBJECTIVES The anticholinergic risk scale (ARS) score is associated with the number of anticholinergic side effects in older outpatients. We tested the hypothesis that high ARS scores are negatively associated with "global" parameters of physical function (Barthel Index, primary outcome) and predict length of stay and in-hospital mortality (secondary(More)
OBJECTIVE although the isolated effects of age on QT interval and QT dispersion (QTd) have been previously investigated, no data are available on the simultaneous effects of age and other physiological or lifestyle factors on QT interval and QTd in healthy subjects. We studied the effects of age, gender, body mass index, smoking status, and blood pressure(More)
PURPOSE Studies on the risk of stroke in users of non-steroidal anti-inflammatory drugs (NSAIDs) have provided conflicting results. We studied the association between the use of non-selective ns-NSAIDs, selective COX-2 inhibitors, or either of these NSAIDs, and the incidence of stroke-related hospitalization in elderly subjects. METHODS We conducted a(More)
Asymmetric dimethylarginine (ADMA), an endogenous methylated form of the amino acid L-arginine, inhibits the activity of the enzyme endothelial nitric oxide synthase (eNOS), with consequent reduced synthesis of nitric oxide (NO). An increased synthesis and/or a reduced catabolism of ADMA might contribute to the onset and progression of atherosclerosis and(More)
An increasing body of evidence supports the existence of a strong link between inflammation, endothelial dysfunction, and the onset and progression of atherosclerosis. However, a cause-effect relationship between these phenomena has not been demonstrated yet. Although some inflammatory markers, such as C-reactive protein, have been recently shown to improve(More)
