[Hypertension in the elderly: definition, indications for treatment and clarification]

Hypertension is the single most potent common and remediable risk factor for cardiovascular morbidity and mortality in the population over age 65. Data from newer intervention studies show that it is clearly beneficial to treat elderly patients with either both systolic and diastolic hypertension or with isolated systolic hypertension. The indication to start treatment in a given patient depends on blood pressure values, age and eventual concomitant disease. In the evaluation of the elderly hypertensive patient, multiple blood pressure measurements in the standing and lying patient should be taken. In the case of suspected carotid artery stenosis, a Doppler ultrasound is indicated before starting antihypertensive therapy. Finally, if refractory hypertension or kidney failure develop in an elderly patient, renal artery stenosis should be considered.
