[Salt sensitive blood pressure and the renin-angiotensin system in hypertension].
The relationship between (excessive) use of sodium chloride and the blood pressure is still equivocal. Blood pressure responses to alterations in dietary salt consumption vary greatly between individuals, which has led to the concept of salt sensitivity. Although the mechanisms which determine the degree of salt sensitivity are not fully understood, the renin-angiotensin system seems to play a key role. A relative inability of this system to respond promptly to alterations in salt intake may underlie the development of salt sensitivity. By administering drugs which block the renin-angiotensin system to patients with essential hypertension, blood pressure is rendered more sensitive to the effects of salt restriction and (or) diuretic treatment.
