Among 137 depressed cardiac patients, lower baseline physical health-related quality of life (HRQoL) was independently associated with greater depression persistence at 6 months among patients randomized to collaborative care, but not usual care. Low physical HRQoL may impact collaborative care effectiveness and indicate a need for alternate depression treatment.
