Abstract

The prevalence and natural history of severe proteinuria in mild to moderate hypertension are not completely defined. We screened 1635 men with a history of hypertension and randomized 1292 with untreated diastolic blood pressure (DBP) 95-109 mmHg to single-drug treatment with either hydrochlorothiazide, atenolol, captopril, clonidine, diltiazem-SR, prazosin, or placebo in a double-blind prospective trial. Twenty-seven of 1635 patients (1.7%) satisfying clinical criteria for primary hypertension were found to have developed proteinuria > 1000 mg/24 hours and were removed from the study. Follow-up data were obtained on 19 of these 27 patients. One patient was found to have focal segmental sclerosis and progressed to end-stage renal disease. Three other patients developed severe (serum creatinine > 3.5 mg/dl) chronic renal failure (one with diabetic nephropathy), one progressed from serum creatinine 1.4 to 2.2 mg/dl, but 14 of the 19 remained with stable serum creatinine < 2.0 mg/dl on follow-up for 6-9 years. Data were available for 1076 of 1155 (93%) treated study patients at end titration, 522/600 (87%) at one year and 322/444 (73%) at two years. There were significant associations for proteinuria with obesity and higher systo...Continue Reading

Antihypertensive drugs are used to treat hypertension (high blood pressure) which aims to prevent the complications of high blood pressure, such as stroke and myocardial infarction. Discover the latest research on antihypertensive drugs and their mechanism of action here.
