1. A method, comprising:
- detecting an event corresponding to a myocardial infarction; and
in response to a detected event corresponding to a myocardial infarction, decreasing coronary vascular resistance and increasing blood flow by applying a baroreflex therapy using an electrode positioned proximate to a baroreflex neural targetto reduce pressure through a neural pathway that includes nerves that control dilation of blood vessels.

Abstract
An aspect of the present subject relates to an implantable medical system. An embodiment of the system includes a baroreflex stimulator, a myocardial infarction detector, and a controller. The baroreflex stimulator applies a baroreflex stimulation signal through an electrode. The myocardial infarction detector detects an event indicative of myocardial infarction. The controller is connected to the baroreflex stimulator and to the myocardial infarction detector, and is adapted to apply a baroreflex therapy in response to a detected event indicative of myocardial infarction. Other aspects are provided herein.

13. A method, comprising:
-
automatically detecting a myocardial infarction; and in response to detecting a myocardial infarction event, decreasing coronary vascular resistance and increasing blood flow by applying a baroreflex therapy to stimulate sensory nerve endings sensitive to increased pressure in a blood vessel using an electrode positioned within the blood vessel, wherein the sensory nerve endings function as receptors of a baroreflex mechanism to reduce pressure, wherein applying a baroreflex therapy includes applying a baroreflex therapy to stimulate sensory nerve endings sensitive to increased pressure in a pulmonary artery using an electrode positioned in the pulmonary artery. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
