• A figurative interdependence between the heart and sadness has long existed in language and in literature.
• In 1628, English physician William Harvey noted “every affection of the mind that is attended either with pain or pleasure, hope or fear, is the cause of an agitation whose influence extends to the heart”

Biobehavioral variables and mortality or cardiac arrest in the Cardiac Arrhythmia Pilot Study (CAPS)
• 502 pts with >10PVC/hr or >5 NSVT episodes evaluated
• Results indicated that higher levels of depression and lower pulse rate reactivity were significant risk factors for death or cardiac arrest, after adjusting statistically for a set of known
clinical predictors of disease severity.

Depression and 18-Month Prognosis After Myocardial
Infarction • 18month follow-up showed that both DIS and BDI scores
consistent with depression were significantly related to 18month cardiac mortality, after controlling for other predictors of mortality including Killip class, PVCs, previous MI. (OR 3.64, p=0.012 and OR 7.82, p=0.0002 with adjusted OR6.64, p=0.0026)
• The deaths that occurred in 18month follow-up were concentrated among depressed patients with PVCs >10/hr.

Depression and Long-term Mortality Risk in Patients with Coronary Artery Disease
• 1250 patients with CAD assessed for depression and followed for 15.2 years to evaluate the long-term mortality risk.
• Pts were enrolled at the time of LHC and followed at 6 and 12 months then annually with SDS.
Am J Cardiol 1996;78:613-617

• Higher depression scores were associated with increased risk of subsequent cardiac death (p=0.002) and total mortality (p<0.001) after controlling for initial disease severity and treatment.
• Pts with moderate to severe depression had a 69% greater odds of cardiac death and a 78% greater odds of mortality from all causes than nondepressed patients.
• Pts with higher scores had a higher risk of cardiac death >5 yrs later (p<0.005)

Effect of Depression on Late (8 years) Mortality After Myocardial Infarction
• Prospective observational study of 284 patients hospitalized with MI
• Any depression at the time of MI was not associated with mortality at 8 years.
• However, increased mortality was statistically significant in the short term (4 months).

Usefulness of Persistent Symptoms of Depression to Predict Physical Health Status 12 Months After an
Acute Coronary Syndrome• 425 pts hospitalized for ACS completed the BDI and SF-12 in
hospital, 6- and 12 months later.
• Only patients with persistent symptoms of depression were at risk for poorer physical health.
• Patients with newly developed depressive symptoms after ACS had a trend toward worse physical health, whereas patients with transient depressive symptoms were not at
increased risk.

Depression Is a Risk Factor for Coronary Artery Disease in Men: The Precursors Study
• Observational study of 1190 male medical students enrolled from 1948 to 1964 followed for 40 years
• Incidence of depression was 12%. In multivariate analyses, these men were at greater risk for subsequent CAD (RR 2.12) and MI (RR 2.12).
• The increased risk associated with depression was present even for MIs occurring 10 yrs after the first MDE (RR 2.1)
• The association did not change when time-dependent smoking, EtOH, and coffee use were added to models, nor when BMI, FH of MI, baseline cholesterol, and time-dependent HL were added.
• In a model with the strongest RF, the risk of CHD from depression was still significant with RR of 1.7

• Clinical depression was associated with a greater risk of total mortality according to both unadjusted and adjusted analyses.
• Clinical depression was significantly related to CVD mortality in unadjusted analyses, with a trend toward increased CVD mortality in adjusted analyses.
• The association of clinical depression with CVD mortality was stronger than the association of clinical depression with other
causes of death, exclusive of suicide.

Depression as an Antecedent to Heart Disease Among Women and Men in the NHANES I Study
• 5006 women and 2888 men who completed the CES-D were followed over 10 years.
• 17.5% of women were depressed and 9.7% of men were depressed.
• The mean poverty index was lower in depressed patients.
• Women had 187 nonfatal and 137 fatal events. Men had 187 nonfatal and 129 fatal events.

Immunologic response
• Cytokines may lead to sickness-behavior (lethargia, anorexia, paresthesia, irritability, social withdrawal, impaired concentration, sleep problems, decreased libido; particularly TNF-alfa and IL-6 may induce depression, anxiety and memory impairment)
• In non-melancholic depression elevated levels of -IL-6 (mediates activation of the HPA axis), -NK cells (acute stage)-leucocytes/lymphocytes (acute stage)
• In melancholic depression:- decreased (in vitro) production of IL-2; IFN-g; IL-10 (acute stage), but normal cell counts

The relationship between central nervous system correlates of depression and immune system parameters is bidirectional, mediated by neurohormonal and parasympathetic pathways. Depressive symptoms primarily affect the transition from stable CAD to acute coronary syndromes via plaque activation and prothrombotic processes (solid line) and may adversely affect the initial response to injury at early stages of coronary atherosclerosis (dashed line).

SSRI therapy in patients with ischemic heart disease
• SSRIs reduce platelet activity. SSRI (sertraline) was associated with substantially less release of platelet/endothelial biomarkers: PF4, βTG, platelet/endothelial cell adhesion molecule 1, P selectin, thromboxane B2, 6-keto prostaglandin F1a, vascular cell adhesion molecule 1, and E selectin.

• High prevalence of smoking in depression & vice versa
• Depression decreases smoking cessation rates.
– Physical inactivity
• Depression is inversely associated with exercise, participation in cardiac rehabilitation
– Poor diet and obesity
– Nonadherence to prescribed medications

Depression and Medication Adherence in Outpatients With Coronary Heart Disease
Findings From the Heart and Soul Study
• 14% of depressed pts vs 9% of nondepressed pts reported not taking their medications as prescribed (OR 2.8, p<0.001)
• Twice as many depressed pts as nondepressed pts reported forgetting to take their medications (OR2.4, p<0.001)

Course of Depressive Symptoms and Medication Adherence After Acute Coronary Syndromes
• Depression was associated with medication nonadherence in a gradient fashion.
• 15% of nondepressed pts, 29% of mildly depressed pts, and 37% of mod-severely depressed pts took ASA <80% of the time.
• Change in depressive symptoms over the study period were linearly related to changes in adherence.

Sertraline Treatment of Major Depression in Patients With Acute MI or Unstable Angina
SADHART
• 369 pts with MDD randomized to sertraline (50-200mg/day) or placebo for 24 weeks
• Pts were hospitalized with ACS in the past 30 days and met DSM-IV criteria for MDD.
• The study involved 7 countries from 04/1997-04/2001.
• Primary outcome was change from baseline EF. • Secondary measures included cardiovascular adverse
events, HAM-D scores, CGI-I scores

SADHART• Sertraline had no significant effect on mean LVEF,
incidence of PVCs, or QTc interval.
• The incidence of severe CV adverse events was 14.5% with sertraline and 22.4% with placebo.
• CGI-I but not HAM-D favored sertraline.
• In the groups with preexisting depression, both CGI-I and HAM-D measures were significantly better in those assigned to sertraline.

SADHART
• Sertraline appears to be a safe medication for use following ACS.
• In patients with recurrent depression and CAD, sertraline was efficacious in the treatment of depression.

AHA Recommendations• Routine screening for depression in patients
with CHD in various settings, including the hospital, physician’s office, clinic, and cardiac rehabilitation center.
• The opportunity to screen for and treat depression in cardiac patients should not be missed, as effective depression treatment may improve health outcomes.

AHA Recommendations• Patients with positive screens should be
evaluated by a professional qualified in the diagnosis and management of depression.
• Patients with cardiac disease who are under treatment for depression should be carefully monitored for adherence to their medical care, drug efficacy, and safety with respect to their cardiovascular as well as mental health.

AHA Recommendations• Monitoring mental health may include, but is
not limited to, the assessment of patients receiving antidepressants for possible worsening of depression or suicidality, especially during initial treatment when doses may be adjusted, changed, or discontinued.

Summary
• MDD occurs in 15-23% of patients with coronary disease and is an independent RF for morbidity and mortality.
• RCTs in the 1990s and 2000s show RR of MI and CV mortality of 1.5-2 in pts with preexisting depression.
• In persons with established IHD, depression is associated with a 3-4 fold increase in the risk of subsequent CV morbidity and mortality.
• Treatment of depression in patients with CAD is safe and somewhat efficacious
• Rehabilitation is associated with a 50% decrease in depressive symptoms in pts with CHD
