The present invention provides a method and apparatus for assessing ventricular function on a chronic basis using a plurality of electrodes disposed on or about a left ventricle and / or a right ventricle—and optionally, at least one mechanical or metabolic sensor—all operatively electrically coupled to an implantable medical device. The plurality of electrodes are preferably spaced-apart so that at least one electrode is disposed electrical communication with a discrete volume of ventricular tissue. In one embodiment, the discrete volume of tissue is defined by multiple longitudinal and axial planes as known and used in the medical arts. Thus, according to the present invention, at least one electrode couples to appropriate sensing circuitry and essentially provides a localized electrogram (EGM) that, when compared to other EGMs, provides for configurable, localized delivery of therapeutic pacing stimulus, diverse impedance-sensing vectors, various diagnostic information regarding myocardial function and / or anti-tachycardia pacing.

CAD (computer-aided diagnosis) systems and applications for cardiac imaging are provided, which implement methods to automatically extract and analyze features from a collection of patient information (including image data and / or non-image data) of a subject patient, to provide decision support for various aspects of physician workflow including, for example, automated assessment of regional myocardial function through wall motion analysis, automated diagnosis of heart diseases and conditions such as cardiomyopathy, coronary artery disease and other heart-related medical conditions, and other automated decision support functions. The CAD systems implement machine-learning techniques that use a set of training data obtained (learned) from a database of labeled patient cases in one or more relevant clinical domains and / or expert interpretations of such data to enable the CAD systems to “learn” to analyze patient data and make proper diagnostic assessments and decisions for assisting physician workflow.

Methods are described for using compositions containing platelet-rich plasma for the treatment of a variety of tissue lesions. Particularly, delivery of platelet-rich plasma to connective tissue is described. The described method and compositions have been shown to provide both pain relief and improved mobility in treatment of lateral epicondylitis.

Systems and methods are provided for automated assessment of regional myocardial function using wall motion analysis methods that analyze various features / parameters of patient information (image data and non-image data) obtained from medical records of a patient. For example, a method for providing automatic diagnostic support for cardiac imaging generally comprises obtaining image data of a heart of a patient, obtaining features from the image data of the heart, which are related to motion of the myocardium of the heart, and automatically assessing regional myocardial function of one or more regions of a myocardial wall using the obtained features.

The invention discloses red date lipid-lowering eight-treasure rice pudding. The red date lipid-lowering eight-treasure rice pudding comprises, by weight parts, 138-148 parts of sticky rice, 14-20 parts of red dates, 10-16 parts of peanuts, 6-7 parts of lettuce, 2-3 parts of cherokee rose fruits, 4-5 parts of the root of kudzu vine, 2-3 parts of rehmannia leaves, 1-2 parts of rhodiola rosea, 1-2 parts of flatstem milkvetch seeds, 4-7 parts of gynostemma pentaphylla, 1-2 parts of radix polygonati officinalis, 2-3 parts of cassia seeds, 1-2 parts of sunflower flower plate, and 3-4 part of garlic. The eight-treasure rice pudding is diverse and balanced in nutrition, and suitable for various people, cannot cause harm to human body for long-term consumption, and has the better health care effect. The stick rice being used as main materials of the eight-treasure rice pudding contains protein, fat, saccharides, calcium, phosphorus, iron, vitamin B1, vitamin B2, starch and the like. The eight-treasure rice pudding is rich in nutrition, is warming and strengthening food, has effects of tonifying middle-Jiao and Qi, tonifying the spleen and nourishing the stomach, and stopping abnormal sweating, and has the certain relaxation effect on deficiency-cold in spleen and stomach, poor appetite, and abdominal distension and diarrhea. The sticky rice has the effect of inducing astringency, and has the better dietary therapy effect on frequent micturition and night sweat. The rhodiola rosea can be anti-aging, anti-hypoxic, fatigue-resistant, radiation-resistant, antineoplastic, and antiviral, and can improve brain function and myocardial function. The red date lipid-lowering eight-treasure rice pudding has the effects of relieving cough and asthma, lowering blood fat and the like, and benefits human health.

The present invention relates to a cytopheretic cartridge for use in treating and / or preventing inflammatory conditions that affect myocardial function and to related methods. The cartridge can be used in treating a subject with myocardial dysfunction, such as a subject with chronic heart failure and / or acute decompensated heart failure.

The present invention relates to a method of diagnosing if a subject which has suffered from an acute myocardial infarction is also suffering from a pre-existing myocardial dysfunction, the method comprising a) determining the amount of a natriuretic peptide in a sample of the subject; b) determining the amount of a cardiac troponin in a sample of the subject; c) calculating the ratio (natriuretic peptide / cardiac troponin); and d) diagnosing if the elevated natriuretic peptide level is related to a preexisting myocardial dysfunction or if the elevated level is caused by the acute myocardial infarction, based on the ratio calculated in step c). The method allows determining whether the individual has suffered from a myocardial dysfunction, in particular heart failure, before the myocardial infarction has occurred.
