Brief summary: No suitable treatment has been identified to reverse and ideally prevent, the cardiovascular disease risk associated with depression and anxiety. The purpose of this study is to determine if quetiapine treatment of depression can reverse the signs of arterial stiffening that often occurs in depression and anxiety, and which are believed to be risk factors for future heart disease.

Detailed description: The evidence that depressive and anxiety disorders confer a high relative risk (RR) for cardiovascular disease (CVD) development is clear and compelling. A cadre of inflammation, platelet activation and other biomarkers of endothelial dysfunction strongly suggest multiple and possibly interrelated mechanisms underlying this co-morbidity. Early detection of the vulnerability to develop CVD has become an urgent health issue. However, detection alone of vulnerability without proper therapeutic intervention aimed at reversing it, is merely of scientific interest. The evidence to date that antidepressant drugs, while highly efficacious in restoring euthymia, may not normalize the biomarkers of CVD vulnerability. Hence, there is a need to identify other pharmacologic interventions for depression. Quetiapine, due to its unique molecular structure and unique pharmacological profile, belongs to none of the known classes of antidepressants. However, quetiapine clearly has antidepressant and anti-anxiety efficacies. Now, we propose to explore whether quetiapine can reverse those pathophysiological changes occurring in mixed depression/anxiety that have been linked causally to the development of CVD. Accordingly, the primary purpose of this study is to compare C-Reactive Protein between the treatment and healthy control groups at 12 weeks post treatment.

Eligibility criteria: Inclusion Criteria:

* Use of any of the following cytochrome P450 inducers in the 14 days preceding enrolment including but not limited to: phenytoin, carbamazepine, barbiturates, rifampin, St. John's Wort, and glucocorticoids
* Concomitant use of any other antidepressant, anxiolytic, or antipsychotic agent
* Administration of a depot antipsychotic injection within one dosing interval (for the depot) before the study begins
* Substance or alcohol dependence at enrolment (except dependence in full remission, and except for caffeine or nicotine dependence), as defined by DSM-IV criteria
* History of heavy smoking within the preceding 6 months
* Opiates, amphetamine, barbiturate, cocaine, cannabis, or hallucinogen abuse by DSM-IV criteria within 4 weeks prior to enrolment

* Medical conditions that would affect absorption, distribution, metabolism, or excretion of study treatment
* Unstable or inadequately treated medical illness (e.g. diabetes, angina pectoris, hypertension) as judged by the investigator
* Involvement in the planning and conduct of the study
* Previous enrolment in the present study.
* Participation in another drug trial within 4 weeks prior enrolment into this study or longer in accordance with local requirements
* A patient with Diabetes Mellitus (DM) fulfilling one of the following criteria:

  * Unstable DM defined as enrolment glycosylated hemoglobin (HbA1c) \>8.5%.
  * Admitted to hospital for treatment of DM or DM related illness in past 12 weeks.
  * Not under physician care for DM
  * Physician responsible for patient's DM care has not indicated that patient's DM is controlled.
  * Physician responsible for patient's DM care has not approved patient's participation in the study
