Plasma angiotensins and blood pressure during converting enzyme inhibition.
The relationship between plasma angiotensin and the reduction of blood pressure with the angiotensin converting enzyme inhibitor enalapril was studied in rats. Blood pressure was measured in conscious rats with indwelling arterial catheters. To measure angiotensin II, plasma was analyzed by physical separation of angiotensins using high performance liquid chromatography followed by radioimmunoa...
متن کاملConverting enzyme inhibition and blood pressure reactivity to psychological stressors.
There is considerable interest in blood pressure reactivity to psychological stressors. Because the sympathetic nervous system and the renin-angiotensin system are so responsive to stressors and are themselves the targets of many antihypertensive medications, many investigators have wondered if such medications decrease the blood pressure response to stressful stimuli. We studied 25 normotensiv...
متن کاملHormonal and blood pressure changes during converting enzyme inhibition by teprotide.
Changes induced by i.v. and subcutaneous teprotide in plasma renin, angiotensin I, angiotensin II, aldosterone and bradykinin were studied in a renal transplant patient with severe high renin hypertension, before and after trinephrectomy. The immediate reduction in BP produced by teprotide was not solely attributable to the inhibition of conversion of angiotensin I to angiotensin II, because th...
متن کاملEffects of angiotensin-converting enzyme inhibitors on central blood pressure.
Effects of Angiotensin-Converting Enzyme Inhibitors on Central Blood Pressure To the Editor: From a substudy of the Australian National Blood Pressure 2 (ANBP2) trial, Dart et al1 concluded that there was no evidence for a disproportionate lowering of central systolic pressure to explain the favorable effects of an angiotensin-converting enzyme inhibitor over diuretic in the main ANBP2 study. R...
متن کاملEffects of angiotensin-converting enzyme inhibition on plasma aldosterone concentration, plasma renin activity, and blood pressure in spontaneously hypertensive cats with chronic renal disease.
Hypertension is commonly associated with chronic renal disease in cats, and inappropriate activation of the renin-angiotensin-aldosterone system (RAAS) may contribute to the hypertensive state. Angiotensin-converting enzyme (ACE) inhibitors are commonly administered when hypertension is present to decrease plasma concentrations of angiotensin II and aldosterone, which cause vasoconstriction and...
