Q

By what direct mechanisms can stress worsen medical conditions?

A
  • Direct stress activates the hypothalamic pituitary-adrenocortical axis (HPA) causing cortisol secretion and the sympathetic-adrenal-medullary system (SAM) causing catecholamine secretion.
  • Plausible these systems are having direct effects at a cellular level but the final pathways are less clear.

Stress increases risk of heart disease. (catecholamine release which increases vascular resistance in the body which increases risk of ischaemia)

  • Stress cardiomyopathy - ‘broken heart syndrome’
  • Positive stress can also cause heart problems

Q

What coping strategies exist?

A

Problem focused

More and more patients are very much aware of their condition

Patients may join support networks and support groups. Some patients however, don’t like joining support groups ‘I don’t want to see what my future is going to be like’. Other patients go and find it enormously helpful.

Some patients may participate in treatment/lifestyle changes, such as excersise and starting hobbies.
