title: [Blood pressure parameters and cardiovascular risk in the elderly].
abstract: The treatment decision must take into account the benefit and risks related to the intervention: the benefit demonstrated and quantified in many therapeutic trials in hypertension in the elderly, but also the patient's initial risk. It is now recognized that, in elderly hypertensive patients, systolic blood pressure is a better predictor of morbid and lethal events related to hypertension than diastolic blood pressure. Recent data in the medical literature attribute a predictive role to pulse pressure which is even greater than that of systolic blood pressure. From a pathophysiological point of view, the level of pulse pressure reflects the degree of rigidity of large arterial trunks. The arterial rigidity parameter could integrate the harmful effect of "cardiovascular risk factors" (hypertension, but also atherogenic dyslipidaemia, diabetes, smoking, homocysteine, genetic factors, etc.) on the years or decades of exposure, and pulsed pressure would therefore appear to be a better marker of cardiovascular risk than other blood pressure parameters. Pulse pressure should therefore be integrated into the benefit/risk ratio of antihypertensive treatment in the elderly.
