Abstract

RATIONALE: Nitric oxide (NO) bioavailability is reduced in the setting of heart failure. Nitrite (NO2) is a critically important NO intermediate that is metabolized to NO during pathological states. We have previously demonstrated that sodium nitrite ameliorates acute myocardial ischemia/reperfusion injury. OBJECTIVE: No evidence exists as to whether increasing NO bioavailability via nitrite therapy attenuates heart failure severity after pressure-overload-induced hypertrophy. METHODS AND RESULTS: Serum from patients with heart failure exhibited significantly decreased nitrosothiol and cGMP levels. Transverse aortic constriction was performed in mice at 10 to 12 weeks. Sodium nitrite (50 mg/L) or saline vehicle was administered daily in the drinking water postoperative from day 1 for 9 weeks. Echocardiography was performed at baseline and at 1, 3, 6, and 9 weeks after transverse aortic constriction to assess left ventricular dimensions and ejection fraction. We observed increased cardiac nitrite, nitrosothiol, and cGMP levels in mice treated with nitrite. Sodium nitrite preserved left ventricular ejection fraction and improved left ventricular dimensions at 9 weeks (P<0.001 versus vehicle). In addition, circulating and cardiac brain natriuretic peptide levels were attenuated in mice receiving nitrite (P<0.05 versus vehicle). Western blot analyses revealed upregulation of Akt-endothelial nitric oxide-nitric oxide-cGMP-GS3Kβ signaling early in the progression of hypertrophy and heart failure. CONCLUSIONS: These results support the emerging concept that nitrite therapy may be a viable clinical option for increasing NO levels and may have a practical clinical use in the treatment of heart failure.

  • Bhushan et al. reported that dietary nitrite supplementation in drinking water (50 mg/L sodium nitrite, for nine weeks) increased cardiac nitrite, nitrosothiol, and cGMP levels, which improved left ventricular function during heart failure in mice with hypertension produced by transverse aortic constriction.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
