ILO 2: describe and explain the pathophysiology of CHD

what is meant by the term 'plaque'

a sticky deposit

describe a healthy artery

an artery that is free of any blockages and can vasodilate/vasoconstrict as needed

describe an artery that has CHD

Less blood can flow through as the plaque is blocking the heart

define the term atherosclerosis

The hardening of the plaque within the coronary arteries

how does the sympton of angina relate to the pathophysiology of CHD

the narrowing of the artery is limiting the oxygen deliver to the cardiac tissue causing hypoxia

how does the symptom of pain throughout the body relate to the pathophysiology of CHD

angina singals pain receptors from the heart to the rest of the body

how does the symptom of shortness of breath relate to the pathophysiology of CHD

as the heart is hypoxic so it's less efficient at pumping blood, which results in hypoxia in other areas of the body

how does the symptom of feeling faint relate to the pathophysiology of CHD

ineffiency of heart pumping results in a lack of blood flow to the brain

discuss the physical consequences of CHD if left untreated

hypoxic cardiac muscle → portion of heart to die → myocardial infarction(heart attack) → death(if left untreated)

discuss the psychological consequences of CHD

-distress

-worries of a heart attack

-fustrations due to withdrawals (quit smoking)
