Abstract

Background —Elevated C-reactive protein (CRP) serum levels, an exquisitely sensitive objective marker of inflammation, relate to long-term prognosis in patients with coronary artery disease and in apparently healthy men. Because abnormalities of endothelial regulation of vascular function may contribute to the occurrence of coronary events, we tested the hypothesis that elevated CRP levels are associated with an abnormal systemic endothelial vascular reactivity. Methods and Results —Endothelium-dependent (10 to 50 μg/min acetylcholine) and endothelium-independent (2 to 8 μg/min sodium nitroprusside) forearm blood flow responses were measured with venous occlusion plethysmography in 60 male patients with angiographically documented coronary artery disease. Forearm blood flow responses to acetylcholine were inversely correlated with CRP serum levels ( r =−0.46, P =0.001). With multivariate analysis that included the classic risk factors for coronary artery disease, elevated CRP serum level remained a statistically significant independent predictor of a blunted endothelial vasodilator capacity. Most important, normalization of elevated CRP levels over time was associated with a normalization of endothelium-mediated forearm blood flow responses after 3 months. Conclusions —Thus, elevated CRP serum levels indicative of a systemic inflammatory response are associated with a blunted systemic endothelial vasodilator function. The identification of elevated CRP levels as a transient independent risk factor for endothelial dysfunction might provide an important clue to link a systemic marker of inflammation to atherosclerotic disease progression.

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.
