1. A method executable by an implantable medical device (IMD) to detect ischemia in a patient'"'"'s heart, the method comprising the steps of:

  • receiving data about at least one physiologic parameter related to the severity of an ischemic episode of a patient'"'"'s heart via an IMD;

    processing the data within the IMD to determine the severity of the ischemic episode, wherein said severity is deemed higher according to preselected criteria;

    in the event that the severity of the ischemic episode exceeds a present value of a variable threshold, providing an alert signal from the IMD to the patient, wherein the alert signal is determined as a function of the severity of the ischemic episode; and

    modulating a palliative ischemia therapy based on the relative severity of the ischemic episodewherein the processing step comprises the steps of determining whether the ischemic episode can be classified as a stable ischemic episode or an unstable ischemic episode.
