[Hypotensions in the elderly: Clinical and therapeutic features]. / Hypotensions du sujet âgé : aspects cliniques et thérapeutiques.

Hypotension and especially very low diastolic blood pressure could be an at-risk situation in very old and frail patients and in those with coronary heart disease. Chronic hypotension in people with heart failure is an indicator of poor prognosis and hinders the management of therapy. Orthostatic hypotension is a decrease in blood pressure>20mmHg for systolic and/or>10mmHg for diastolic within 3minutes after transition from supine to upright. Orthostatic hypotension may be symptomatic or not. The search for orthostatic hypotension is part of the clinical examination of elderly patients with hypertension, falling, diabetes and or polymedication. First intention treatment aims to correct modifiable modifying factors and to limit the circulatory consequences of orthostatism by elastic venous compression.
