86 results about "Coronary vascular disease" patented technology

Coronary artery disease — also called coronary vascular, arteriosclerotic and ischemic heart disease — remains the leading cause of death in the United States. The disease is caused by arteriosclerosis or "hardening of the arteries," which interferes with the normal flow of blood to the heart.

Method and System for Non-Invasive Assessment of Coronary Artery Disease

A method and system for non-invasive patient-specific assessment of coronary artery disease is disclosed. An anatomical model of a coronary artery is generated from medical image data. A velocity of blood in the coronary artery is estimated based on a spatio-temporal representation of contrast agent propagation in the medical image data. Blood flow is simulated in the anatomical model of the coronary artery using a computational fluid dynamics (CFD) simulation using the estimated velocity of the blood in the coronary artery as a boundary condition.

Catheter devices and methods for their use in the treatment of calcified vascular occlusions

Catheter devices and methods for their use in enhancing fluid flow through a vascular site occupied by a vascular occlusion are provided. The subject catheter devices include at least a first, second and third lumen, where: (a) the first lumen is used for delivery of an acidic dissolution solution to the vascular site; (b) the second lumen is used for delivery of a buffer solution to the vascular site; and (c) the third lumen is used for removal of fluid from the vascular site. In many preferred embodiments, the first, second and third lumens are coaxial. In practicing the subject methods, the vascular site is flushed simultaneously with an acidic dissolution fluid and a buffer solution, where flushing is carried out in a manner such that only a surface of the vascular occlusion is contacted with the acidic dissolution fluid and the remainder of the vascular site is not contacted with fluid having a pH that is lower than about 4. Flushing is carried out in this manner for a period of time sufficient for fluid flow through the vascular site to be enhanced, e.g. increased or established. The subject catheter devices and methods find use in the treatment of a variety of different vascular diseases characterized by the presence of calcified vascular occlusions, including peripheral and coronary vascular diseases.

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.

Onset of force development as a marker of thrombin generation

Platelet contractile force (PCF) is used as a surrogate marker of thrombin generation. PCF generation occurs concomitant with the burst of prothrombin fragment F 1+2 release. The time between assay start and PCF onset is identified as the thrombin generation time (TGT), and is used in assessing risk of bleeding, in diagnosing various disorders, and in monitoring the effects of pharmaceutical and other treatments. TGT is prolonged in clotting factor deficiencies and in the presence of direct and indirect thrombin inhibitors. TGT shortens to normal with clotting factor replacement and shortens with administration of rVIIa. TGT is short in thrombophilic states such as coronary artery disease, diabetes and thromboangiitis obliterans and prolongs toward normal with oral and intravenous anticoagulants.
