Summary
Although the traditional determinant of renal dysfunction in heart failure was suggested as
decreased cardiac output and renal hypo perfusion, recent studies have demonstrated the
association of persistent systemic venous congestion and kidney dysfunction. Relief of the
congestion has demonstrated to improve renal functions in decompensated heart failure. The
current trial was set up to investigate the changes of renal venous impedance and renal
arteriolar resistivity indices with diuretic therapy, in patients with congestive renal
failure. The investigators asked whether measurement of renal venous impedance index or renal
arteriolar resistivity index can guide the practice of diuretic therapy.
