8 results about "Cardiac ischaemia" patented technology

Systems and Methods are disclosed for detecting acute coronary syndrome (ACS) events, arrythmias, heart rate abnormalities, medication problems such as non-compliance or ineffective amount or type of medication, and demand / supply related cardiac ischemia. The system may have both implanted and external components that communicate with a Physicians's programmer, and smart-devices for monitoring and alerting to detected medically relevant events or states. At least one processor provides event detection using statistical threshold criteria calculated upon at least a portion of a patient's data / distributions and set for a patient or based upon what a doctor determines as abnormal for a patient. A power management system provides at least 2 strategies of evaluating power level including at least obtaining a voltage measure and measuring and calculating a cumulative capacity measure and comparing these two measure to their respective thresholds.

Reganoxonin is used in the preparation of a drug for the detection of ischemic heart disease by echocardiography. Echocardiography is selected from one or more of stress echocardiography, myocardial angiography, transthoracic Doppler echocardiography, and two-dimensional speckle tracking echocardiography. Ischemic heart disease is selected from one or more of non-obstructive or obstructive ischemic heart disease. The diagnosis of the patient's disease by administering the drug has good accuracy, sensitivity, specificity, and safety.

The invention discloses a mitochondrial delivery system of macrophages in a targeted heart ischemia reperfusion injury area as well as a preparation method and application of the mitochondrial delivery system, and relates to the technical field of biomedical engineering. The mitochondrial delivery system comprises an active mitochondrial and a physiological platelet coupled to the surface of the active mitochondrial and capable of expressing a membrane protein P-selectin. The mitochondrial delivery system provided by the invention can be adhered to the surface of circulating monocytes through physiological platelet membrane protein P-selectin, recruits by virtue of inflammatory cells, and is accurately targeted to the aggregation part of monocytes and macrophages of ischemic myocardium; and then active mitochondria is transplanted to the inflammatory macrophages to achieve the effect of relieving the heart ischemia reperfusion injury, so that the defects of the existing mitochondria targeting delivery technology are partially solved, the potential influence on other healthy organs can be avoided while the myocardial ischemia reperfusion injury is relieved, the side effect is reduced, and the clinical application prospect is broad. The efficient delivery of active mitochondria is realized.
