Abstract

Background —Levels of tumor necrosis factor-α (TNF-α) increase with acute ischemia. However, whether elevations of TNF-α in the stable phase after myocardial ischemia (MI) are associated with increased risk of recurrent coronary events is unknown. Methods and Results —A nested case-control design was used to compare TNF-α levels obtained an average of 8.9 months after initial MI among 272 participants in the Cholesterol And Recurrent Events (CARE) trial who subsequently developed recurrent nonfatal MI or a fatal cardiovascular event (cases) and from an equal number of age- and sex-matched participants who remained free of these events during follow-up (controls). Overall, TNF-α levels were significantly higher among cases than controls (2.84 versus 2.57 pg/mL, P =0.02). The excess risk of recurrent coronary events after MI was predominantly seen among those with the highest levels of TNF-α, such that those with levels in excess of 4.17 pg/mL (the 95th percentile of the control distribution) had an ≈3-fold increase in risk (RR=2.7, 95% CI 1.4 to 5.2, P =0.004). Risk estimates were independent of other risk factors and were similar in subgroup analyses limited to cardiovascular death (RR=2.1) or to recurrent nonfatal MI (RR=3.2). Conclusions —Plasma concentrations of TNF-α are persistently elevated among post-MI patients at increased risk for recurrent coronary events. These data support the hypothesis that a persistent inflammatory instability is present among stable patients at increased vascular risk. Novel therapies designed to attenuate inflammation may thus represent a new direction in the treatment of MI.

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.
