摘要： A pacing system delivers cardiac protective pacing therapy (CPPT) to protect the heart from injuries and/or to treat existing injuries. The pacing system receives a set of inputs and delivers optimized cardiac protection pacing tailored for different purposes. The system delivers electrical stimulation to modulate myocardial strain for anti-atherosclerosis therapy and/or to provide therapy for myocardial infarction (MI). In one embodiment, a medical device for treating atherosclerosis is provided. The medical device includes a sensing circuit to receive sensed signals to identify areas of coronary artery disease (CAD) or areas at risk for CAD using the sensed signals. The device also includes a pacemaker circuit adapted to deliver an electrical signal through at least one electrode to a myocardial target adjacent to the identified areas. According to various embodiments, a controller communicates with the sensing circuit and controls the pacemaker circuit to provide intermittent electrical stimulation to the myocardial target to induce periods of stretch on the vessel due to induce myocardial strain changes. The stimulation is targeted to attenuate or prevent atherosclerosis associated with the CAD, according to various embodiments.

摘要： This document discusses, among other things, an apparatus comprising at least one implantable cardiac depolarization sensing circuit, an electrical stimulation circuit, and a pacing mode controller. The implantable cardiac depolarization sensing circuit is configured to obtain a sensed depolarization signal from a ventricle and the electrical stimulation circuit is configured to provide pacing electrical stimulation energy to at least one implantable ventricular electrode. The pacing mode controller delivers pacing therapy according to a first pacing mode that is a normal operating mode, and delivers pacing therapy according to second and third pacing modes. The second and third pacing modes increase mechanical stress on at least a particular portion of the ventricle as compared to the pacing therapy delivered during the first pacing mode. The pacing mode controller alternates between the second and third pacing modes when switched from the normal operating mode to a stress augmentation mode.

摘要： A pacing system delivers cardiac protection pacing to protect the heart from injuries. The pacing system receives a set of inputs and calculates parameters for delivering optimized cardiac protection pacing tailored for different stress levels. The system automatically adjusts heart rate to optimize cardiac protection pacing in a closed-loop system. In one embodiment, a method for delivering pacing pulses for cardiac protection is provided. Intrinsic atrioventricular (AV) intervals are sensed. The intrinsic AV interval and a predetermined equation relating the AV interval to an optimal AV delay are used to provide a maximum positive rate of left ventricular pressure change during systole. An AV delay is calculated using a predetermined percentage of the optimal AV delay to deliver ventricular pacing pulses to provide a desired level of stress for cardiac protective pacing therapy (CPPT) to provide a cardiac conditioning therapy to improve autonomic balance.

摘要： A pacing system delivers cardiac protective pacing therapy (CPPT) to protect the heart from injuries and/or to treat existing injuries. The pacing system receives a set of inputs and delivers optimized cardiac protection pacing tailored for each of different purposes. The system delivers electrical stimulation to provide therapy for angina and/or to provide therapy for co-morbidities related to neural imbalance. In one embodiment, a method for treating angina is provided. A signal is sensed indicative of an incidence of angina and an angina region being a myocardial region affected by the angina. The incidence of angina is detected and the angina region is located. A pacing location is selected remote from the angina region, and CPPT is initiated at the pacing location. The CPPT is adapted to create increased stress at the angina region, to promote mass-redistribution and angiogenesis at the angina region to treat the angina.

摘要： Cardioprotective pre-excitation pacing may be applied to stress or de-stress a particular myocardial region delivering of pacing pulses in a manner that causes a dyssynchronous contraction. Such dyssynchronous contractions are responsible for the desired cardioprotective effects of pre-excitation pacing but may also be hazardous. Described herein is a method and system that uses measures of a patient's physiological response to ventricular dyssynchrony to control the duty cycles of intermittent pre-excitation pacing.
