title: [Renal digital angiography in the study of hypertensive patients].
abstract: 50 patients, 31 male and 19 female with mean age of 45.1 +/- 9.4 years afflicted with blood hypertension (BH) were studied. RDA was performed on all of them as part of the etiological study. The variables evaluated were: systolic blood pressure (SBP), diastolic blood pressure (DBP), therapy index (TI), evolution time of its BH and type of BH (refractory BH, severe BH, mild-moderate BH). The organ affliction was also evaluated (renal function, ECG, presence of cardiomyopathy, vascular disease, and retinopathy. RDA alteration appeared in 16 cases, 1 (10%) in refractory BH group, 8 (28.6%) in severe BH group, and 7 (58.3%) in mild-moderate BH group. A shorter BH evolution period having been observed in patients with altered RDA than in those with normal RDA (3.49 +/- 3.96 years vs 6.93 +/- 4.68 years p = 0.01). We conclude that only this variable is a feature for suspicion of renovascular BH, without an apparent difference between the results of RDA and those of I.V. urography, obtained during the diagnosis screening. The significant differences observed between the mild-moderate BH and the other groups suggests that the clinical suspicion, and not the severity of the BH, is the point which should determine the patients to be renovascularly explored.
