摘要: Systems and methods for managing cardiac information concerning a patient are provided. In some aspects, cardiac information objects are displayed graphically at an interface having at least two axes. Time is displayed on a first axis of the at least two axes and parameters of the cardiac information objects are displayed on a second axis of the at least two axes. Each cardiac information object is spatially associated with at least a portion of the time displayed and a parameter displayed. In some aspects, the interface advantageously allows a user to conveniently view and manage the cardiac information objects.

摘要: Systems, methods, and sensor devices for identifying one or more changes in a stimulus-responsive hydrogel include a sensor device having (i) a sensing structure and (ii) a stimulus-responsive hydrogel associated with a first side of the sensing structure. The sensing structure includes a flexible thin film polymer and an electric sensing element capable of electric impedance change, and the hydrogel is configured to dimensionally change in response to predefined stimuli such that a dimensional change of the hydrogel causes a change in an impedance property of the electric sensing element. Systems including such a sensor device can additionally include a meter in electrical communication with the sensor device to identify changes in the impedance properties of the structure and/or a catheter sheath configured for placement within an in vivo environment and is sized and shaped to receive the sensor device within a lumen thereof.

摘要: A method of treating hypertension in a mammal is described, including: by focused sound energy, heating at least one nerve at a surface of a renal artery in a mammal; during the heating and by magnetic resonance imaging, repeatedly determining thermal levels in each of first and second volumetric zones of a region that includes at least a portion of the surface, the second zone being adjacent to the first zone; after determining that an indicium of a thermal level in the first zone exceeds a first threshold, and upon determining that an indicium of a thermal level in the second zone exceeds a second threshold, ceasing the heating of the at least one nerve for at least three months; and as a result of the heating, lowering a blood pressure in the mammal.

摘要: Certain embodiments provide a method of assessing a risk of thromboembolic stroke in a patient. The method comprises acquiring image data and determining an indicator of a degree of fibrosis of a patient's left atrium (LA) based on the image data. The method also comprises estimating a level of risk of thromboembolic stroke of the patient based on the indicator.

摘要: Certain embodiments of the invention provide methods of assessing a patient's risk for atrial fibrillation (AF) recurrence after receiving treatment with an AF treatment modality, that include determining, from left atrium (LA) tissue image data of a patient, a level of a parameter that is positively proportional to an amount of unhealthy tissue in a wall of the LA of the patient; and outputting, to an output device, an indicator of a comparison between (i) the determined level and (ii) a first threshold level of the parameter, the first threshold level derived from LA tissue image data of at least one other patient, who experienced an AF recurrence after treatment with the AF treatment modality. In certain embodiments, levels of the parameter equal to or greater than the first threshold level are indicative of a significant risk of AF recurrence after treatment with the AF treatment modality.
