APPARATUS AND METHODS FOR TREATMENT OF ATHEROSCLEROSIS AND INFARCTION

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.
