AIMS: Advanced heart failure (AdvHF) poses significant treatment challenges, particularly when mechanical circulatory support or transplant options are unavailable, highlighting a gap in evidence-based medical management. The aim of this study was to evaluate the safety and effectiveness of sodium nitroprusside infusion (SNP) for enhancing systemic and renal perfusion in patients with AdvHF, with or without concomitant inotropic support.
METHODS AND RESULTS: We retrospectively analyzed the medical records of 406 patients with AdvHF admitted between October 2014 and September 2018 who received nocturnal SNP infusions for at least one week. In 55 patients with symptomatic hypotension or signs of peripheral hypoperfusion (differential systemic BP < 15 mmHg), continuous dobutamine infusion was added. In a subset of 155 patients who required multiple hospitalizations (median 3), data from the last hospitalization were used. No symptomatic hypotension leading to discontinuation of SNP (mean dose: 0.5 ± 0.1 μg/kg/min) was reported. Patients showed a significant increase in differential systemic blood pressure after infusion (29.2 ± 8.1 to 36.8 ± 11.6 mmHg, p < 0.001) independent of dobutamine use. Administration of SNP and dobutamine resulted in greater weight loss compared to SNP alone (-5.33 ± 7.02 vs -3.32 ± 4.0 kg, p < 0.003), but it was also associated with a significant increase in creatinine levels compared to SNP alone (+0.24 ± 0.87 vs +0.02 ± 0.43, p = 0.005).
CONCLUSIONS: The results show that SNP is a safe therapeutic choice in AdvHF patients with or without concomitant inotropic support and highlight the potential efficacy of nitroprusside in improving systemic and renal perfusion in these advanced patients.
