Agenda (2)

Mind/Body Medicine

How processes of the mind influence the bodyBi-directional relationshipHippocrates: 4 humors affect mind and bodyDescartes: mind-body dualismModern Medicine:

Body in isolation (reductionism)However inevitable influence of the “subject”

e.g. placebo effect, emotions (e.g. anger, etc)

Mind/Body Medicine

“The separation of psychology from the premises of biology is purely

artificial because the human psyche lives in indissoluble union with the

body”

– Carl Jung

The Stress ResponseStressHans Seyle (1950’s) – “a non-specific result of any

demandupon the body”Engle (1962) – “all processes, external or internal whichimpose a demand or requirement upon the person”

Stress - triggered by a perceived threat or need to adapt - generates a cascade of biochemical events

which affect:

Autonomic nervous systemMusculoskeletal systemPsychoneuroendocrine system

Psychoneuroendocrine system

Limbic system : integrates - thoughts(locus cereleus) - feelings

- emotionsHypothalamus: regulates - homeostasis

- SNS : mind/body feedback

Anger and Cardiovascular Disease

Barefoot - Anger profile of CAD patents- Degree of CA blockage directly related to level of anger

Anger and Cardiovascular Disease

Williams Psychosomatic medicine (1983)- 255 medical students- 2 groups: Hostile - 119

Not hostile - 136

- 20 yr. later: Hostile -16 diedNot hostile - 3 died

Anger and Cardiovascular Disease

Other Studies

- Anger Episodes: Post MI patients E.F. 7%

- Hostile Patients: 2-3x mortality rate within first decade after an MI

- Anger single most common emotion in two hours preceding an MI

Psychological Stress & Myocardial Ischemia:

Possible mechanisms

1. Sympathetically mediated increase in –Heart rateBlood pressureMyocardial contractility/workloadOxygen consumption

2. Enhanced coronary vasomotor tone caused by circulating vasoconstrictors

Anxiety Syndromes

3 large community studiessignificant relationship to

sudden cardiac deathMechanisms: Vent arrhythmias,

Altered cardiac autonomic tone

Chronic Stress and Hypertension

Puerto Rico – urban incidence – 18%- rural incidence – none

Increase with “Westernization” of Fiji IslandersIncrease in African Zulus moving from rural to urban centers

Chronic Stress

Unresolved, repetitive stress may lead to:DepressionAnxietyAssociated with:

chronic pain (Turner 1989)susceptibility to common cold (Cohen 1991)hypertension (Benson 1993)Mortality in cancer patientsdecreased immune function

Psychological States and Physical Disease

Depression: mortality and cancer immune function

Anger: Coronary Artery Disease

Anxiety: Coronary Artery Disease

hypothalamic–pituitary–adrenal (HPA) axis and the autonomic nervous system. The stress system influences other endocrine systems (i.e., those controlling gonadal, thyroidal, and growth functions) and exerts complex effects on the immune/inflammatory reaction. The principal CNS centers of the stress system are the corticotropin-releasing hormone (CRH)/arginine vasopressin (AVP) and locus ceruleus–norepi-nephrine neurons of the hypothalamus and brainstem, respectively, which regulate the HPA axis and the sympathetic nervous system. The end hormones of these systems, glucocorticoids and the catecholamines, act to maintain behavioral, cardiovascular, metabolic, and immune homeostasis during stress.1,2,5,6 and 7,7a
