Biomarkers for cardiovascular diseases and methods using the same
View Patent ↗Biomarkers relating to cardiovascular disease, including atherosclerosis and cardiomyopathy, are provided, as well as methods for using such biomarkers as biomarkers for cardiovascular disease. In addition, methods for modulating the respective disorders or conditions of a subject are also provided. Also provided are suites of small molecule entities as biomarkers for cardiovascular disease, including atherosclerosis and cardiomyopathy.
1. A method treating a cardiovascular disease in a subject, the method comprising:
a) performing or having performed an assay using liquid chromatography-mass spectrometry to analyze a biological sample obtained from the subject to determine the levels of three or more biomarkers for a cardiovascular disease in the sample, wherein the three or more biomarkers are selected from the group consisting of sebacate, phenylalanine, histidine, 1,5-anhydroglucitol (1,5-AG), 2-hydroxybutyrate (AHB), oleate (18:1), and combinations thereof;
b) determining the levels of the three or more biomarkers in the sample;
c) performing analysis of the levels of the three or more biomarkers to determine whether the subject has or is predisposed to having a cardiovascular disease, wherein the analysis includes comparing the determined levels of the three or more biomarkers in the sample to cardiovascular disease-positive and/or cardiovascular disease-negative reference levels of the three or more biomarkers in order to determine if the subject has or is predisposed to having a cardiovascular disease; and
d) administering an effective treatment to the subject if the subject is determined to have or to be predisposed to having a cardiovascular disease, wherein effective treatment comprises one or more of prescribing dietary restrictions, exercise, or early-stage drug treatment; administering an effective amount of a composition to the subject; or administering an effective amount of one or more biomarker(s) that are lowered in the subject diagnosed with cardiovascular disease as compared to a healthy subject not having cardiovascular disease.
2. The method of claim 1 , wherein the method comprises analyzing the biological sample to determine the level of four or more biomarkers.
3. The method of claim 1 , wherein the method comprises analyzing the biological sample to determine the level of five or more biomarkers.
4. The method of claim 1 , wherein the cardiovascular disease is cardiomyopathy.
5. The method of claim 1 , wherein the cardiovascular disease is atherosclerosis.
6. The method of claim 1 , wherein the cardiovascular disease is atherosclerosis, and the method further comprises analyzing the biological sample to determine the level of one or more additional biomarkers selected from the group consisting of 3-methylhistidine, p-cresol sulfate, mannose, glucose, and gluconate.
7. The method of claim 1 , wherein the method further comprises determining the subject's measurements of fasting plasma insulin, fasting plasma pro-insulin, fasting plasma glucose, fasting free fatty acids, HDL-cholesterol, LDL-cholesterol, C-peptide, adiponectin, peptide YY, hemoglobin A1C, waist circumference, body weight, or body mass index.
8. The method of claim 1 , wherein the method further comprises analyzing the biological sample to determine the level of one or more additional biomarkers selected from the group consisting of arachidonate, cholesterol, creatinine, docosahexaenoate (DHA; 22:6n3), glucose, urate 3-methylhistidine, p-cresol sulfate, mannose, glucose, and gluconate.
