[Proteinuria in patients with congestive heart failure. Role of arterial hypertension].
OBJECTIVE
To evaluate the role of arterial hypertension (AH) in the development of proteinuria in patients with decompensated congestive heart failure (CHF).


METHODS
Twenty-four-hour urinary protein determinations were obtained from 30 patients with decompensated CHF, before and after therapy of CHF. The patients were divided in two groups according with the presence of AH as cause of CHF: group A, 18 patients with CHF due to AH and group B, 12 patients with CHF due to idiopathic dilated or chagasic cardiomyopathy without previous AH.


RESULTS
There was no differences between the groups concerning age, sex, renal function and duration of CHF. Before treatment, 88% of group A presented proteinuria exceeding 150 mg/24h compared to 25% of group B (p < 0.01). After treatment of CHF, proteinuria > 150 mg/24 h remained in 38% of group A and in none of group B. Proteinuria did not reverse after 6 months of follow-up in 2 patients, one of them showed benign nephrosclerosis in renal biopsy.


CONCLUSIONS
Patients with decompensated CHF, unrelated to AH, presented mild proteinuria reversible after the treatment, that improved renal function. In patients with CHF due to AH, proteinuria was more frequent, more severe and did not improve after the treatment, suggesting renal lesion.
