The effect of nesiritide on renal function and other clinical parameters in patients with decompensated heart failure...

The role of nesiritide in patients with decompensated heart failure with preserved ejection fraction (dHFpEF) has not been previously studied. In this investigation, the authors retrospectively analyzed the effect of nesiritide on renal function and clinical outcomes in patients admitted with dHFpEF. Of the 658 patients included, 328 were treated with nesiritide while 330 patients were treated with standard diuretic therapy. In both the nesiritide and no nesiritide groups, there was a significant change in mean glomerular filtration rate (GFR) and creatinine at 72 hours as well as at day of discharge (P<.001). This trend did not progress at 1 month in the nesiritide group, although it did in the no nesiritide group. At 1 month after therapy, however, there was a significant difference between the two groups in the mean change of GFR and creatinine (P<.001). There was no significant difference in >25% decrease of GFR anytime through day 30 (25% vs 29.69%, P=.236) between the two groups. On multivariate analysis, nesiritide was an important predictor of renal function at 1 month (P<.05). Thus, nesiritide can be administered safely without negatively impacting long-term renal function in patients admitted with dHFpEF.
