214 results about "Endothelins" patented technology

Endothelins are peptides with receptors and effects in many body organs. Endothelin constricts blood vessels and raises blood pressure. The endothelins are normally kept in balance by other mechanisms, but when overexpressed, they contribute to high blood pressure (hypertension), heart disease, and potentially other diseases.

Method for detecting coronary endothelial dysfunction and early atherosclerosis

InactiveUS20080058642A1Reduce incidenceReduce riskTomographyAngiographyTherapeutic treatmentCoronary Artery Disease Risk
A method of detecting endothelin receptor A mediated coronary microvascular endothelial dysfunction in an asymptomatic subject is disclosed. The method comprises obtaining sets of noninvasive cardiac PET perfusion images of the subject before and after administration of selective endothelin receptor A (ETA receptor) antagonist. The images are analyzed, including application of applying Markovian homogeneity analysis, and the results are compared to detect improvement, or lack of improvement, of myocardial perfusion homogeneity in the subject. A result of improved myocardial perfusion homogeneity after administration of the antagonist indicates the presence of ETA receptor-mediated microvascular endothelial dysfunction in the subject and indicates therapeutic treatment to improve endothelial function and / or to reduce coronary artery disease risk factors.

System for managing laboratory test results for patients taking an endothelin receptor antagonist

The invention provides a system and method of collecting, storing and managing laboratory test results of patients. In one embodiment the invention is directed towards collecting, storing and managing laboratory test results of patients taking an endothelin receptor antagonist (ERA). The system provides a way of securely collecting and tracking information from a plurality of patients, a plurality of laboratories, and a plurality of health care providers by use of a database. The method comprises receiving patient information from health care providers, receiving a laboratory test schedule for each patient, and laboratory tests needed for each patient. This data is entered into a central processing computer. The patients then go to any laboratory to have the monthly testing done due to the ERA prescription. The laboratory test data collected is sent to the central processing computer. The central processing computer can generate an automated report on the laboratory results and supply the results to the health care provider. Additionally, if no laboratory test data for the patient is entered into the central processing computer in accordance with the laboratory test schedule for the patient, the central processing computer will notify a call center which will call the patient, laboratory or health care provider informing them of the overdue laboratory test data.
