[Treatment of hypertension in arteritic patients].
The treatment of hypertension in arteritic patients must take account of several parameters: respective severity of hypertension and of arteriopathy, possibility of other sites of atherosclerosis and supposed cause of hypertension. The association of essential hypertension and of an arteriopathy does not sum up all possibilities. Hypertension may be purely systolic, due to decreased compliance. A stenosis of the renal arteries is also worth evoking in the context of an already symptomatic atherosclerotic disease. For the confirmation of the latter hypothesis, Doppler associated to echography may be an alternative to the intravenous or intra-arterial opacification of the renal arteries. In case of moderate hypertension (diastolic pressure ranging from 90 to 104 mmHg), non-medicamentous treatments should be preferred: low-sodium diet, suppression of tobacco and other risk factors, weight loss. Beta-blockers, whatever their class, reduce the walking distance in case of intermittent claudication. Though not formally contraindicated, especially when their use is justified by an associated coronary insufficiency, they are not advised in hypertensive arteritic patients. On the other hand, captopril allows both reducing blood pressure and preserving the walking distance. However, a prerequisite to the possible use of agents inhibiting the conversion enzyme is the preliminary search for a stenosis of the renal arteries. In fact, when these medications are carelessly used in case of bilateral stenosis or of stenosis on a functionally single kidney, they entail a risk of renal failure or of thrombosis of the stenosed renal artery. Calcium inhibiting agents are also anti-hypertensive substances of choice in hypertensive arteritic subjects.(ABSTRACT TRUNCATED AT 250 WORDS)
