Disease outline
Congestive heart failure (CHF) is known as the disorder in which the human heart
becomes weaker in pumping blood throughout the body (Maru et al., 2016). In this progressive
and critical as well as chronic heart condition, the muscles of the heart ventricles gradually
becomes weaker and hence, the contraction and relaxation process associated to systole and
diastole of heart movement do not occur properly (Voigt et al., 2014). Due to this, the human
heart becomes unable to meet the requirement of blood of entire body and the blood circulation
associated complication of the heart increases (Maru et al., 2016). This is because, while
suffering from congestive heart failure, the heart ventricle do not becomes unable to pump
adequate blood to the bodily organs due to which, all the organs starts accumulating fluid around
their anatomy and hence, the person starts feeling congestive in their heart and distress condition
increases (Voigt et al., 2014). In this case study, all these symptoms were witnessed by Mrs.
Sharon McKenzie (77) and the symptoms were cold feet, swollen feet, breathlessness and others.
Cause, incidence and risk factors
The primary cause of CHF is past experience of Myocardial infarction, as due to this
condition, the heart muscles of the patient becomes weaker and in unfavorable condition, it could
lead to weaker cardiac symptoms and creates CHF condition (Kumar, Ashwlayan & Verma,
2018). It was clearly mentioned that patient Sharon McKenzie (77) had myocardial infarction 12
years ago and hence, she had higher risk of developing chronic CHF. Further, it was seen that
due to bacterial and viral infection, performing excessive work out in spite of weak heart muscles
and hence the chances of CHF increased. Besides this, due to plaque formation in the heart blood

vessels, due to excess consumption of fats. The blood vessel becomes unable to provide adequate
blood to the organs and hence, CHF heart failure associated condition arises (Marzo et al., 2016).
The incidence related to CHF around the world is high as due to increased physical and
environmental stressor, people are prone to suffer from myocardial infarction, However, in
Australia, the data related to congestive heart failure mentions that more than 300,000 people are
affected with this disorder and every year more than 30,000 cases are registered. Further, in this
majority of affected individuals were male over the age of 45. Hence the prevalence for CHF
was higher in older adults than younger individuals (Australian Institute of Health and Welfare,
2019).
Risk factors associated with CHF was related to previous occurrence of myocardial
infarction, due to which the heart muscles becomes weak. Further, increased blood pressure,
weaker heart muscles, diet and nutritional factors, fat or plaque accumulation in the blood vessels
were other reasons for the CHF condition (Liu & Gao, 2017).
Further, this health condition affected Mr. Sharon McKenzie’s (77) family by breaking
their morale. It was seen that the patient’s husband used to take her for walks so that they could
spend some quality time together. Further, it was seen that her husband used to take care of her
health condition. Hence, this condition affected the overall health of her condition (Marzo et al.,
2016).
Answer 2
Sign & symptoms Underlying pathophysiology
Shortness of breath Due to weaker heart muscles. Heart could not
meet the requirement of the body, due to
which, the organs of the body starts
accumulating fluids around it, Due to this
