Abstract/OtherAbstract:
We describe our observations concerning differences in two groups of young hypertensive patients according to their renin activities after ACE inhibition. Seventeen of these patients (age 26 +/- 7 years), so far untreated, were investigated prospectively for hormone levels (renin, aldosterone, vasopressin), microalbuminuria, renal haemodynamics (inulin and PAH clearance) and signs of organ damage (echocardiography, fundoscopy). Secondary forms of hypertension were excluded by routine methods, including angiography. We differentiated two groups of young hypertensive patients. Group 1 (n = 9) had a false positive captopril test with elevated renin activities after ACE inhibition with captopril (8.4 +/- 5 ng/ml per hour) compared to group 2 (renin activity: 2.2 +/- 1.3 ng/ml per hour) or an increase of greater than 400% of renin activity after ACE inhibition. Baseline renin activities and sodium excretion did not differ between the groups. Group 1 also showed significantly greater GFR, FF, and microalbuminuria, as well as signs of organ damage, with left ventricular hypertrophy and hypertensive changes in fundoscopy. There were no differences between the groups concerning mean arterial blood pressure and duration of hypertension. In conclusion, we were able to demonstrate that patients with highly stimulated renin activities showed signs of visceral organ damage and renal hyperfiltration compared to the normal renin activity group after ACE inhibition. Investigations of the renin-angiotensin-aldosterone system with ACE inhibitors might constitute a helpful indicator of renal changes and organ damages in young hypertensive patients.
