Increased Osteoprotegerin Serum Levels in Men with Coronary Artery Disease
Abstract
Osteoprotegerin (OPG) regulates osteoclast and immune functions and appears to represent a protective factor for the vascular system. However, the role of OPG in human atherosclerosis has not been evaluated. In this study, we assessed OPG serum levels in 522 age-matched men who, on the basis of coronary angiography, had either absence of coronary artery disease (CAD) or presence of single-vessel disease, double-vessel disease, or severe triple-vessel disease. OPG serum levels were positively correlated with age (r = 0.28; P < 0.001) and were higher in men with diabetes mellitus (P < 0.01). OPG serum levels in men without CAD were 5.4 +/- 2.0 pmol/liter, compared with 6.1 +/- 2.1 pmol/liter in single-vessel disease (P < 0.005), 5.9 +/- 2.4 in double-vessel disease (P < 0.05), and 6.3 +/- 2.3 pmol/liter in triple-vessel disease (P < 0.001). Moreover, OPG serum levels were positively correlated with the severity of CAD as determined by a CAD scoring system (r = 0.17; P < 0.01). In conclusion, our data underline that OPG serum levels are associated with the severity of CAD and are increased in elderly men and patients with diabetes mellitus. We conclude that increased OPG serum levels may reflect advanced cardiovascular disease in men.

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.
