Physiologic consequences of increased vascular oxidant stresses in hypercholesterolemia and atherosclerosis: Implications for impaired vasomotion

Harrison, David G., Ohara, Yuichi·1995·The American Journal of Cardiology

Abstract

During the past 8 years, it has become apparent that endothelium-dependent vascular relaxation is abnormal in a variety of disease states, including hypercholesterolemia, atherosclerosis, diabetes, hypertension, and following heart transplantation. Our laboratory and several others have examined dysfunctional regulation of vasomotor tone in hypercholesterolemia and atherosclerosis. These studies have led to the concepts that altered regulation of vasomotion by the endothelium (1) is an early development in atherosclerosis, (2) involves both large vessels (with overt atherosclerosis) and the microcirculation (in which atherosclerosis does not develop), and (3) can be reversed by lipid-lowering strategies. The mechanisms for the abnormalities underlying this form of endothelial dysfunction are likely multifactorial, but a major underlying factor appears to be increased oxidant degradation of endothelium-derived nitric oxide. In this review we examine the evidence supporting this conclusion and consider the implications of these findings.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Excess superoxide or other ROS in the cell causes modification of different parts of the cellular machinery and is a known player in the genesis and progression of cardiovascular disease.

    “The excess of superoxide, or other ROS, in the cell causes the modification of different parts of the cellular machinery and is a known player in the genesis and progression of cardiovascular disease (227, 408, 409, 570, 672, 700, 893).”

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.
