50 results about "Ventricular hypertrophy" patented technology

Techniques are provided for predicting the onset of a heart condition within a patient based on impedance measurements. Briefly, overloads in fluid levels in the thorax and in ventricular myocardial mass within the patient are detected based on impedance signals sensed using implanted electrodes. The onset of certain heart conditions is then predicted based on the overloads. For example, pulmonary edema arising due to diastolic heart failure is predicted based on the detection of on-going overloads in both fluid levels and ventricular mass. Ventricular hypertrophy is detected based on an on-going ventricular mass overload without a sustained fluid overload. Various other heart conditions may also be predicted based on specific combinations of recent or on-going overloads. Evoked response is exploited to corroborate the predictions. Appropriate warning signals are generated and preemptive therapy is initiated.

The invention relates to purposes of polygonum cuspidatum extract, namely polydatin. Myocardial hypertrophy is the most important reason for triggering congestive heart failure. Ventricular hypertrophy usually involves ventricular structure change, namely ventricular remodeling. The ventricular remodeling is a complication of multiple cardiovascular diseases and a vital and decisive element in the development process of the congestive heart failure. The arrhythmia occurrence rate after the myocardial remodeling is increased by 28%, and cardiac sudden deaths caused in the end are increased by over five times. It is indicated that through in vitro study tests, the polydatin remarkably restrains heart ion channels caused by ischemia indury of mice from remodeling and has a great protective effect for arrhythmia, and therefore the polydatin can be used for preparing products resisting against arrhythmia caused by myocardial hypertrophy and/or ventricular hypertrophy. According to the method, the polydatin plays the anti-arrhythmic role by increasing the electric current density of transient outward potassium current (Ito), shortening the action potential duration (APD) of cardiac muscle cells and restraining the QT inter-phase from being prolonged.
