Cardiovascular Disease and Stress
Soufer, 2012 Comm; J Cardiovasc Med 2008, V9, N8
• 30-50% of patients with CAD exhibit mental-stress induced ischemia in lab testing
• Often ischemia is not accompanied by angina and not explained by physical exertion
• Mental stress hemodynamics are physiologically different from other cardiovascular stressors

Mental Ischemia Mechanisms
Soufer, 2012 Comm; J Cardiovasc Med 2008, V9, N8
• Dec prefrontal cortex activity > Dec parasympathetic activity > Dec HRV and Inc TNF and Dec NO > ischemia
• Inc hippocampus tone > inc cortisol and Inc NE > ischemia
• Ischemia is mostly inferior and posterior• MDD is an independent risk factor for CAD
and a poor prognostic indicator for CAD due to hypercortisolemia, reduced vagal tone, reduced HRV, impaired platelet function

Damasio – The Mental Self
NATURE|VOL 423 | 15 MAY 2003
• mental self represents the individuality and continuity of a living organism.
• the simplest level of self allows us to manufacture the idea that objects and events are perceived from a singular perspective, that of the organism symbolized by the self.
• with the assistance of past memories of objects and events, we can piece together an autobiography and reconstruct our identity and personhood incessantly.
• the body - mind as a whole is the ‘thing-process’ that is symbolized as the mental self
• the brain’s representation of the structure and operations of the body is continuous

Damasio – Evolving the Body-Mind Self
• Humoral – chemical/hormonal to hypothalamus
• Neural – electrochemical
• Interoceptive – viscera, muscular, vestibular
• Humoral – chemical/hormonal

The Role of Inflammation
(Arch Gen Psych, 2010 (67)12) ; Brain Behav Immune, 2011 25(2); Archives General Psych 2008 65(4)
• Hypersympathetic tone with inc NE activates production of inflammatory cytokines
• Relative cortisol resistance or decreased cortisol production enhances inflammation
• Reduced parasympathetic tone increase• Presence of infections• Presence of autoimmune disease• Presence of Visceral Adiposity• Early Adversity > Depression leads to lifelong increase in
inflammatory markers --Blocked by SSRIs or enhancing serotonin but only in those who have elevated levels of inflammation
• At high levels – impaired neurogenesis, enhanced glutamatergic excitotoxicity, monoamine disruption

Stress and Plasticity Sleep Med Rev. 2009 June ; 13(3): 187–194;
• Stress induced atrophy of dendrite spine density in hippocampus and PFC, hypertophy in amygdala
• Plasticity in the adult brain especially in the hippocampus – sleep is essential
• Glucocorticoids, CRF, BDNF, Inflammatory cytokines, monoamines, glutamate, CBT

• Conscious awareness “I can respond as I choose.”
• Relaxation skills: o To let go and get focused
• Clarify deep valueso “How do I want to be?”
• Visualizing/experiencingo responding the new way
• Stress induces NEo Prunes PFC, enhances
amygdala, via a-2 rec
• Excess glutamate due to decreased glial cell activity reduces PFC

• Genetic Gifts = Family History• Early Childhood Challenges = Epigenetic DNA
Methylationo Appears to be irreversible
• Later Stressful Life Events= Epigenetic histone modification
• Treatments can change epigenetic modification of histones but not of DNA
• For example – IL-6 and CRP were more often methylated and thus suppressed in individuals without depression compared to those with depressiono Psychol Med 2011 41(5)

Childhood and Likelihood for Brain Resilience Brain Behav and Immune 2012, 1591 (12)
• Children raised in hygiene environments o Birth to 30yoo Increased inflammation if stressed out as adults
• If raised in non hygiene environment, o there is no association between stress and
inflammation• Microorganisms and parasites exposure in early life
leads to well modulated inflammatory system and stress system
Henri Roca, MD 2-2013 drhenriroca.com
Challenges to Behavior Change
• Met/Met BDNF increases likelihood for decreased mood and neuroplasticity in the face of stress (Biol Psych 2005 62(5))o Leads to rumination rather than enhanced
executive functioningoAttenuated by early social support
Henri Roca, MD 2-2013 drhenriroca.com
Negative Bias• Negative stimuli get more attention and
processing• We generally learn faster from pain than pleasure.• People work harder to avoid a loss than attain an
equal gain (“endowment effect”)• Easy to create learned helplessness, hard to undo• Negative interactions: more powerful than positive • Negative experiences sift into implicit memory.
Henri Roca, MD 2-2013 drhenriroca.com
Negativity BiasNeuroimage 2009 47(3)
• The tendency to perceive danger rather than reward signals
• Associated with short allele of the serotonin transporter (5-HTT-LPR)
• Worsened with early life stressors• Higher startle, higher HR, higher sympathetic tone• Activation in the brainstem, amygdala, cingulate
gyrus, medial prefrontal cortex in response to fear• Influences our interpretation of the world and enhances the
likelihood of triggering a stress response

• Meditationo One study showed sig dec in all anxiety scale scores for
meditation group vs. education group• Small study, poss confounding effects of medication, lack of
true placebo controlo Review of multiple studies found meditation an effective
intervention for high trait anxiety and GAD.• Relaxation training (progressive, release-only,
cue-controlled, differential, rapid, applied)o Review of studies found relaxation effective for dental
phobia, test anxiety, panic d/o, GAD.• Breath work• Imaginal exposure: repeated/gradual exposure
pt learns to cope/manage rather than eliminate stressor

• Setting an intention - “top-down” ; frontal, “bottom-up” limbic
• Relaxing the body - parasympathetic nervous system
• Feeling cared about - social engagement system• Feeling safer - inhibits amygdala/ hippocampus
alarms• Encouraging positive emotion - dopamine,
norepinephrine• Absorbing the benefits - positive implicit
memoriesHenri Roca, MD 2-2013 drhenriroca.com
Biofeedback• Biofeedback: measuring & relaying subject's
quantifiable bodily functions e.g., BP, HR, temp, muscle activity, neurological activity, heart rate variability, sweat gland activity.
• Raises pt's awareness and conscious control of unconscious physiological activities.
• Allows users to gain control of physical processes previously considered an automatic response of the ANS.

The Inner Life of the Heart
• Dually innervated. o Intrinsic – cell to cell creating a more
rapid heart rateo Autonomic Nervous System via
• Vagus Nerve – Parasympathetic• Sympathetic nerves and adrenal
hormones• Vagus is dominant and serves to
conserve cardiac reserve• Vagus creates and controls HRV
Henri Roca, MD 2-2013 drhenriroca.com
Heart Rate Variability (HRV)P. Rainville et al. / International Journal of Psychophysiology 61 (2006) 5– 18
• What is the relevance of HRV?- HRV reflects the autonomic nervous
system (cardiac regulation).- HRV is determined non-invasively.- It is known that abnormal HRV is
related to prognosis of vascular causes of death, progression of coronary atherosclerosis.
Henri Roca, MD 2-2013 drhenriroca.com
HRV TheoryInternational Journal of Psychophysiology 61 (2006) 5 – 18
• Parasympathetic regulation is mediated by the vagus nerve and by acetylcholine o Rapid because the Ach is quickly degraded by acetylcholinesteraseo High frequency changes in the RR intervalo Further coupled with changes in respiration o The increase in intraabdominal pressure during inhaling activates the
baroreceptor reflex and produces rapid increases in heart rate mediated by vagal mechanisms.
o The resulting respiratory sinus arrhythmia (RSA), can be characterized by the amplitude of changes in heart rate within each respiratory cycle, and generally contributes to the high frequency components of HRV.
• Sympathetic regulation is mediated by the release and relatively slow re-uptake of adrenaline.
• Slow changes can result from either sympathetic or parasympathetic activity.

• a sympathetic component;• a parasympathetic component coupled
with respiration (RSA) and reactive to baroreceptor reflex activity
• a parasympathetic component independent from respiration and possibly reflecting top-down neural influences on vagal output.

Cortical Facilitation(coherence)
Frustration
Appreciation
“Negative” emotions such as frustration cause chaotic heart rhythms, part of a physically harmful chain reaction leading to inhibition of the cortex.
However, focusing on a “Positive” emotion such as appreciation creates smooth heart patterns, resulting in cortical facilitation, or coherence.

Serotonin deficiency is
correlated with major
depressive disorder
“A reduction in serotonin synthesis may result in depression, depression may result in a reduction in serotonin synthesis, or a third factor may be responsible for both lowering serotonin synthesis rates and triggering depression.”
Aan Het Rot, et al. (2009) Canadian Medical Association Journal. 180(3): 305-313.

Glutamate is involved in
Depression
“Coverging lines of evidence indicate that the glutamatergic system might be a promising target for a novel antidepressant therapy.”
