Pre-existing major depression predicts in-hospital cardiac complications after acute myocardial infarction
ABSTRACT Depression (MDD) and anxiety have been associated with negative long-term outcomes among patients with acute myocardial infarction (MI).
The objective of the study was to determine whether MDD and anxiety preceding MI were associated with in-hospital post-MI cardiac complications.
Subjects (N=129) underwent psychiatric interviews within 72 hours of MI and were evaluated for five in-hospital cardiac complications (recurrent ischemia, ventricular arrhythmia, ventricular arrhythmia requiring intervention, congestive heart failure, and reinfarction).
Current (pre-MI) MDD was a significant and independent predictor of all complications except recurrent ischemia on multivariate regression analysis. In contrast, pre-MI anxiety was not associated with complications.
These findings underscore the importance of identifying and treating MDD in post-MI patients and those at risk for MI.

ABSTRACT: Depression is common in patients with cardiac illness and is independently associated with elevated morbidity and mortality. There are screening guidelines for depression in cardiac patients, but the feasibility and cost-effectiveness of screening all cardiac patients is controversial. This process may be improved if a subset of cardiac patients at high risk for depression could be identified using information readily available to clinicians and screened. To identify risk factors for a positive depression screen at the time of admission in hospitalized cardiac patients. A total of 561 consecutively screened cardiac inpatients underwent the Patient Health Questionnaire-2 (PHQ-2). A prospective chart review was performed to assess potential risk factors for depression that would be readily available to front-line clinicians. Rates of risk factors were compared between patients with positive and negative PHQ-2 depression screens, and multivariate logistic regression was performed to assess whether specific risk factors were independently associated with positive screens. Of the 561 patients screened, 13.5% (n=76) had a positive depression screen (PHQ-2≥2). In the univariate analyses, several variables were associated with a positive depression screen. On multivariate analysis, an elevated white blood cell (WBC) count (>10×10(9) cells per liter) and prescription of an antidepressant on admission were independently associated with a positive depression screen, while current smoking showed a trend toward significance. Information on these three identified risk factors (WBC count, antidepressant use, and smoking) is readily available to clinicians, and patients with these diagnoses may represent a cohort who would benefit from targeted depression screening in certain settings.Journal of Cardiology 03/2012; 60(1):72-7.

ABSTRACT: We lack evidence that routine screening for depression in patients with coronary heart disease (CHD) improves patient outcome. This lack has challenged the advisory issued by the American Heart Association (AHA) to routinely screen for depression in CHD patients. We assess the AHA advisory in the context of well-established criteria of screening for diseases. Using principles and criteria for screening developed by the World Health Organization and the United Kingdom National Screening Committee, we generated criteria pertinent to screening for depression in CHD patients. To find publications relevant to these criteria and clinical setting, we performed a broadly based literature search on "depression and CHD," supplemented by more focused literature searches. Evidence for an association between depression and CHD is strong. Despite this, the AHA advisory has several limitations. It did not account for the complexity of the association between depression and CHD. It acknowledged there was no evidence that screening for depression leads to improved outcomes in cardiovascular populations but still recommended routine screening without providing an alternative evidence-based explanation. It ignored the paucity of literature about the safety and cost-effectiveness of routine screening for depression in CHD and failed to define the nature and extent of resources needed to implement such a program effectively. We conclude that the AHA advisory is premature. We must first demonstrate the efficacy, safety, and cost-effectiveness of screening and define the resources necessary for its implementation and monitoring. Meanwhile, organizations representing cardiologists, psychiatrists, and general practitioners must coordinate efforts to manage depression and CHD through collaborative care, and work with the policy makers to develop the necessary infrastructure and services delivery system needed to optimize the outcome of depressed and at-risk-for-depression patients suffering from CHD.Journal of psychosomatic research 07/2011; 71(1):6-12.

ABSTRACT: In this article we review practice models for treating common mental disorders in primary care. Novel treatment approaches by primary care providers and specialty providers, including collaborative care and telepsychiatric models, show considerable promise. An understanding of remaining barriers to improved care suggests several possible solutions and future directions for outpatient psychosomatic medicine.Harvard Review of Psychiatry 01/2009; 17(6):353-60.
