1. A lead implantation method, comprising:

  • accessing a heart of a patient, the heart having a heart wall;

    detecting, proximate the heart wall, a target region of the heart wall having a level of abnormal wall motion relative to neighboring regions of the heart wall;

    implanting an electrode of the lead at the target region;

    pre-exciting the target region relative to the neighboring regions of the heart wall using the lead electrode in order to alter stress at the target region for treating cardiac remodeling; and

    adjusting the pre-excitation in accordance with activity level measurements reflective of metabolic demand.
