摘要： A cardiac pacing system controls the progression of a cardiac disorder such as heart failure by delivering cardiac pacing to create or augment regional stress in the heart. The cardiac pacing is delivered intermittently, such as on a periodic basis, according to a cardiac stress augmentation pacing sequence that includes alternating pacing and non-pacing periods. One or more physiological signals are monitored for closed-loop control of the cardiac pacing using baseline characteristics of the cardiac disorder, acute cardiac stress created by the cardiac pacing, and/or risk associated with the cardiac pacing.

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.

The pacing mode controller is configured to deliver pacing therapy according to a first pacing mode that is a normal operating mode, and to deliver 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 pacing is changed from the normal operating mode to a stress augmentation mode. The pacing mode controller suspends the change from the normal operating mode to the stress augmentation mode when a condition to prevent the change is detected.
