The present invention relates to methods and devices for predicting restenosis, and for treating atherosclerosis to prevent or reduce the incidence of restenosis. Methods of predicting restenosis in a stenosed peripheral artery may include quantitative histology of the vessel. For example, a method of treating a stenosed artery (and particularly a peripheral artery) may include the steps of determining a level of hypercellularity and one or more of the lipid-richness and extent of inflammatory cell inclusion in the tissue. An index of restenosis based on the hypercellularity and lipid richness and / or extent of inflammatory cell inclusion in the tissue may be determined. Systems for treating or preventing restenosis may include one or more imaging modalities for imaging tissue regions and determining the level of hypercellularity and one or more of the degree of lipid-richness and the extent of inflammatory cell inclusion in the tissue region.

The present invention addresses the treatment of age-related macular degeneration, and treatment of individuals with impaired visual function such as impaired dark adaptation, using regulation of pathogenic mechanisms similar to atherosclerosis. In further specific embodiments, compositions that increase reverse cholesterol transport are utilized as therapeutic targets for age-related macular degeneration and improving impaired dark adaptation. In a specific embodiment, the lipid content of the retinal pigment epithelium, and / or Bruch's membrane is reduced by delivering Apolipoprotein A1, particularly a mimetic peptide.

The invention relates to a method of identifying / monitoring active atherosclerotic plaques associated with blood vessel walls wherein the plaques comprise activated macrophages having accessible binding sites for a ligand. The method comprises the steps of administering to a patient being evaluated for atherosclerosis an effective amount of a composition comprising a conjugate of a ligand and a chromophore capable of emitting light under predetermined conditions, allowing sufficient time for the ligand conjugate to bind to the activated macrophages, subjecting the blood vessels to the predetermined conditions using a catheter-based device, and identifying active plaques by detecting light emitted by the chromophore using a catheter-based device or by using an external imaging technique. The invention also relates to a similar method wherein a chemical moiety capable of emitting radiation is conjugated to the ligand.

The present invention provides for a method to prevent accelerated atherosclerosis in a subject predisposed thereto which comprises administering to the subject a polypeptide derived from soluble receptor for advanced glycation endproduct in an amount effective to prevent accelerated atherosclerosis in the subject. The present invention also provides for a method to prevent a macrovessel disease in a subject predisposed thereto which comprises administering to the subject a polypeptide derived from soluble receptor for advanced glycation endproduct in an amount effective to prevent macrovessel disease in the subject.

An animal model of coronary heart disease has been developed where myocardial infarct can be induced by altering the animal's diet. In all embodiments, this animal model is a result of reduced activity of scavenger receptor class BI (SR-BI) and apolipoprotein E (ApoE). In a preferred embodiment, the model is a result of crossbreeding two transgenic mouse lines: a knockout of SR-BI (SR-BI− / −) and an impaired ApoE expressor (hypoE). The impaired ApoE gene results in only 2-5% expression of ApoE and a reduction in cholesterol homeostasis. Resulting animals are predisposed to hypercholesterolemia but can live longer than a year on a normal low fat diet. Serum plasma levels can be significantly elevated by changing the animal's diet to one containing high levels of fat and cholesterol. Within a month on a high fat, high cholesterol diet, animals develop atherosclerosis and myocardial infarction occurs. Survival depends on the nature of the diet and the conditions of animal husbandry and can typically be around 20-30 days after administration of the modified diet depending on the specific conditions. Housing the animals alone or in groups significantly affects survival of these animals on a high fat diet. Analysis of B- and T-cell deficient SR-BI / ApoE / RAG2 triple knockout mice established that B- and T-lymphocytes do not play a key role in the pathophysiology of the SR-BI ApoE dKO model of human disease. These animal models can be used to study mechanisms and progression of CHD as a function of diet, treatment with drugs to be screened for efficacy or undesirable side effects, and social environmental effects.

The present invention relates to compositions and methods for the reduction of atherosclerotic plaques and the decrease in the level of total serum cholesterol, triglycerides, serum LDL cholesterol, and serum HDL cholesterol.

The invention provides drugs used for treating atherosclerotic diseases such as carotid artery stenosis, lower extremity atherosclerotic occlusive disease, and coronary heart disease, and more specifically discloses applications of compound Szeto-Schiller-31 (SS-31) in preparing drugs or preparations used for treating atherosclerosis and related diseases, and belongs to the field of medicine, and more specifically belongs to the field of novel pharmaceutical applications of compounds. It is found via experiments that SS-31 is capable of reducing atherosclerosis degree, reducing mouse arterial ROS level obviously, reducing oxidative damage, increasing ATP level, reducing the content of macrophages at atherosclerotic plaques obviously, increasing the content of smooth muscle cells and the content of collagen at atherosclerotic plaques obviously, stabilizing atherosclerotic plaques, improving inflammation level obviously, and reducing expression of lipid intake protein at atherosclerotic plaques; and it is shown by results that SS-31 is capable of treating atherosclerosis and related diseases.

The invention relates to a non-invasive skin free-cholesterol detection device for evaluating the atherosclerosis risk. A palm part of a tester is coated with a specific reagent, the relative content of free cholesterol on the skin of the tester can be acquired by measuring the variation situation of a reaction reagent reflection spectrum by utilizing an optical method, and then the risk for a subject suffering the atherosclerosis disease can be further evaluated.
