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

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 • Stress induces NE

o Prunes PFC, enhances
amygdala, via a-2 rec
• Relaxation skills:
o To let go and get focused
• Excess glutamate due to
decreased glial cell
activity reduces PFC
• Clarify deep values
o “How do I want to be?”
• Visualizing/experiencing
o responding the new way

o 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 depression

Childhood and Likelihood for Brain
Resilience

• Children raised in hygiene environments
o Birth to 30yo
o 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

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 functioning
o Attenuated by early social support

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 Bias
Neuroimage 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

Relaxation Techniques
Jorm AF MJA 2004;181:S29-S46; Van der Watt, Current Opinion in Psychiatry 2008,21:37-42
• Meditation
o 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 control
o Review of multiple studies found meditation an effective
intervention for high trait anxiety and GAD.
• Relaxation training (progressive, release-only, cuecontrolled, 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

Cognitive Development,22:406-430; SCAN, 2, 313-322
• Setting an intention - “top-down” ; frontal, “bottomup” 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 memories

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 rate
o 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

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

HRV Theory
International 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 acetylcholinesterase
o High frequency changes in the RR interval
o 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 reuptake of adrenaline.
• Slow changes can result from either sympathetic or parasympathetic activity.
Henri Roca, MD 2-2013

3 Domains of HRV
International Journal of Psychophysiology 61 (2006) 5 – 18
• 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.

“Negative” emotions such as
frustration cause chaotic heart
rhythms, part of a physically
harmful chain reaction leading
to inhibition of the cortex.
Cortical

(coherence)
However, focusing on a
“Positive” emotion such as
appreciation creates smooth

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.”
