Abstract

Background —Although patients with heart failure express elevated circulating levels of tumor necrosis factor-α (TNF-α) in their peripheral circulation, the structural and functional effects of circulating levels of pathophysiologically relevant concentrations of TNF-α on the heart are not known. Methods and Results —Osmotic infusion pumps containing either diluent or TNF-α were implanted into the peritoneal cavity of rats. The rate of TNF-α infusion was titrated to obtain systemic levels of biologically active TNF-α comparable to those reported in patients with heart failure (≈80 to 100 U/mL), and the animals were examined serially for 15 days. Two-dimensional echocardiography was used to assess changes in left ventricular (LV) structure (remodeling) and LV function. Video edge detection was used to assess isolated cell mechanics, and standard histological techniques were used to assess changes in the volume composition of LV cardiac myocytes and the extracellular matrix. The reversibility of cytokine-induced effects was determined either by removal of the osmotic infusion pumps on day 15 or by treatment of the animals with a soluble TNF-α antagonist (TNFR:Fc). The results of this study show that a continuous infusion of TNF-α led to a time-dependent depression in LV function, cardiac myocyte shortening, and LV dilation that were at least partially reversible by removal of the osmotic infusion pumps or treatment of the animals with TNFR:Fc. Conclusions —These studies suggest that pathophysiologically relevant concentrations of TNF-α are sufficient to mimic certain aspects of the phenotype observed in experimental and clinical models of heart failure.

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.
