Dyslipidemias and Microcirculation

Padró, Teresa, Vilahur, Gemma, Badimon, Lina·2018·Current Pharmaceutical Design

Abstract

Dyslipidemia is widely accepted as one of the major risk factors in cardiovascular disease mainly due to its contribution in the pathogenesis of atherosclerosis in medium-sized and large arteries. However, it has become increasingly accepted that high-cholesterol levels can also adversely affect the microvasculature prior to the development of overt atherosclerosis. Moreover, hypercholesterolemia has shown, in preclinical animal models, to exert detrimental effects beyond the vascular tree leading to larger infarcts and adverse cardiac remodeling post-myocardial infarction. At a functional level, hypercholesterolemia has shown to impair endotheliumdependent vasodilation because on defects on nitric oxide bioavailability. The pathogenic mechanisms underlying microvascular dysfunction involve an enhanced arginase activity, enhanced production of free radicals and the activation, recruitment and accumulation of leukocytes, primarily neutrophils, via their diffusion through postcapillary venules. In turn, recruited inflammatory cells and certain inflammatory mediators enhance platelet adhesion, overall inducing a proinflammatory and prothrombotic phenotype. Within the present review, we aim to discuss the existing evidence regarding the presence of dyslipidemia - particularly high low density lipoprotein-cholesterol levels - and the occurrence of microvascular dysfunction, the mechanism by which high cholesterol levels induce functional alterations in the microvascular bed and, finally comment on the impact of dislipidemia-induced microvascular dysfunction at the myocardial level.

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

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?

  • Small and dense LDL particles have an increased capacity to penetrate the arterial wall and are more readily oxidized compared with large and buoyant particles, contributing to atherosclerotic plaque 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.
