Experience with the renal scintigraphic captopril test in an elderly population.

Abstract

The records of 18 consecutive patients referred to a Veterans Administration Hospital nuclear medicine service for renal scintigraphic tests to rule out renovascular hypertension were reviewed. The men were elderly (mean age, 62 years), and risk factors for untoward reactions, including long-standing hypertension, severe peripheral vascular disease, diabetes, chronic renal failure, and recent diuretic use were present. Despite these risks, there was no test morbidity, and the authors conclude that the renal scintigraphic test with captopril enhancement is well tolerated and deserves continued application and evaluation.
