title: [Comparison of treatment effects with an angiotensin converting enzyme inhibitor--lisinopril and a calcium blocker--nifedipine retard on urinary albumin excretion in patients with non-complicated essential hypertension].
abstract: The purpose of the study was to compare the effect of treatment with an angiotensin converting enzyme inhibitor (Lisinopril, MSD) or calcium blocker (Nifedipine retard, MSD) treatment during three months on blood pressure (measured with sphygmomanometric method and ambulatory blood pressure monitoring--ABPM) and urinary albumin excretion in essential hypertension class I acc. to WHO. Fifteen untreated patients aged 38 +/- 5 years with essential hypertension participated in the study and received diet with normal sodium content. Urinary albumin excretion was measured by RIA method in two 24 hour urine collections and mean value was calculated. ABPM was measured with Spacelabs monitor. After first examination 8 patients were randomly selected for the treatment with lisinopril and 7 patients to the treatment with nifedipine. The doses of both drugs were gradually adjusted to reach diastolic blood pressure below 90 mmHg. After 3 months of treatment urinary albumin excretion and blood pressure was found in both after treatment in patients treated with lisinopril but not in those receiving nifedipine. In patients treated with lisinopril a correlation between the decrease in systolic and diastolic blood pressure (measured by ABPM) and decrease of urinary albumin excretion was demonstrated. It was concluded that the normalization of blood pressure induced by lisinopril treatment in patients with uncomplicated essential hypertension and normoalbuminuria is accompanied with significant diminution of urinary albumin excretion which suggests preventive action of the drug in the development of microalbuminuria. Diminution of urinary albumin excretion caused by lisinopril is probably due to both the decrease of blood pressure and the specific renal action of the drug.
