This section provides a summary of the area of practice for this unit and highlights the importance of this topic to general practice and the role of the GP.

Cardiovascular disease (CVD), including acute and chronic heart disease, stroke and peripheral vascular disease, is a complex and multifactorial issue that affects 16.6% of the Australian population.1,2 It is the leading cause of death in Australia and accounts for 26% of all deaths.3 CVD also costs the Australian economy over $5 billion each year, more than any other disease.4

CVD mortality rates for Aboriginal and Torres Strait Islander adults (older than 25 years) are double that of non-Indigenous Australians, and seven times higher in those aged 40–54 years.5 Early intervention in the form of screening and risk factor modification is therefore vital. Screening for CVD in Aboriginal and Torres Strait Islander peoples is recommended from 18 years of age, and screening for CVD risk factors is recommended to start as early as 12 years of age.5

General practitioners (GPs) are well placed to advise patients on how to modify their risk factor profiles through the promotion of healthy lifestyle choices. Risk factors include smoking tobacco, high body mass index (BMI), physical inactivity, elevated cholesterol, elevated blood pressure, excessive alcohol intake, and low fruit and vegetable consumption. These are considered the most effective areas to focus on for CVD prevention.5

Atrial fibrillation is another common cardiac condition that significantly increases the risk of developing heart failure or stroke, making diagnosis and timely management vital.6 These patients are often managed entirely by GPs, with an emphasis on managing symptoms, preventing disease progression and avoiding hospitalisations.

Some cardiovascular conditions also affect children and can have long-term negative health outcomes. These include congenital heart defects and infectious diseases, such as rheumatic fever. The rates of acute rheumatic fever are higher in Aboriginal and Torres Strait Islander children, especially in rural and remote areas.7 If left undiagnosed and untreated, rheumatic fever can lead to rheumatic heart disease.8 It is the GP’s role to identify those at risk and provide appropriate treatment in the context of their community. Other types of sclerotic valvular pathologies are often picked up by GPs by undertaking opportunistic cardiovascular examinations when patients present for other reasons. GPs are also responsible for identifying and appropriately managing these to prevent later morbidity and mortality.

Deaths from heart disease are more than 50% higher for Australians in rural and remote areas of Australia compared with metropolitan areas.8 Research shows that this is due to multiple issues related to access, including the ability to pay, transport and geographical distances, delays in patients seeking care, access to diagnostic testing and timely treatment in an appropriate facility. Workforce shortages or lack of access to relevant non-GP specialists, cultural differences and complexities that arise from comorbidities and geographical isolation also amplify the challenges.9 GPs therefore play a key role in advocating for equitable access to cardiovascular and other general health services for patients in rural and remote areas. GPs working in rural and remote regions should also be supported to provide comprehensive cardiovascular healthcare with the resources they have available locally.

Instructions

This section includes tips related to this unit from experienced GPs. This list is in no way exhaustive but gives you tips to consider applying to your practice.

Extension exercise: Speak to your study group or colleagues to see if they have further tips to add to the list.

  1. Have a low threshold for suspecting silent ischaemia in those with risk factors or those who present with dyspnoea only. This is an under-recognised condition with poorer outcomes due to a delay in diagnosis.
  2. Do not underestimate the power of your therapeutic relationship. Repeated brief motivational interviewing can help patients make significant lifestyle changes over time. 
  3. Don’t forget to screen for heart failure in patients presenting with shortness of breath.
  4. In new-onset chest or abdominal pain, remember to consider acute coronary syndrome (ACS) and dissecting aneurysms as differentials.
  5. Always ask about claudication in a patient presenting with limb pain.
  6. It doesn’t take long to lay hands on a patient. Much can be gleaned from the simple opportunistic assessment of vital signs, heart and lung sounds. This applies to children just as much as adults.

Instructions

  1. Read this example of a common case consultation for this unit in general practice.
  2. Thinking about the case example, reflect on and answer the questions in the table below.

You can do this either on your own or with a study partner or supervisor.

The questions in the table below are ordered according to the RACGP clinical exam assessment areas and domains, to prompt you to think about different aspects of the case example.

Note that these are examples only of questions that may be asked in your assessments.

Extension exercise: Create your own questions or develop a new case to further your learning.

Cardiovascular health

Lila, a 55-year-old woman, presents with fluctuating epigastric pain for a few days. She thinks that her symptoms might have improved slightly after taking an antacid. She has a past medical history of type 2 diabetes and hypertension. On examination, the patient is pale. Her vital signs are all within normal limits. BMI is 35. Heart sounds are dual and regular, and chest sounds clear. Abdomen is soft, with mild discomfort in the epigastrium.

Instructions

This section has some suggestions for how you can learn this unit. These learning suggestions will help you apply your knowledge to your clinical practice and build your skills and confidence in all of the broader competencies required of a GP.

There are suggestions for activities to do:

  • on your own
  • with a supervisor or other colleague
  • in a small group
  • with a non-medical person, such as a friend or family member.

Within each learning strategy is a hint about how to self-evaluate your learning in this core unit.

On your own

Review the RACGP’s Red book (guidelines for preventive activities in general practice) and the RACGP’s National guide to a preventive health assessment for Aboriginal and Torres Strait Islander people.

  • Are you familiar with the absolute cardiovascular risk calculator function in your practice software? Is it being documented and used to guide your discussions with patients?
  • Do you find a colour-coded representation (eg the calculator available on the Heart Foundation website) useful to help a patient’s understanding, or not? Are you using any other risk factor calculators?

Do a random case review of 5–10 patients you have recently seen. Is their cardiovascular screening consistent with what is recommended?

  • What preventive activities or lifestyle changes were covered, and which ones were missed?
  • Have you considered checking for related conditions in patients with risk factors for heart disease; for example, peripheral vascular disease and diabetes?

Find brief (1–2 pages) resources to give to patients to support your commonly given advice, such as lowering lipids and how to form healthy habits. This will help to reinforce your own learning and make it easier to find these documents when you need them.

  • Look at the key messages through the patient’s eyes. Is the language appropriate? Are the messages clear? What information would you add or remove if you were writing something similar?

Practise interpreting an ECG using online resources or books of ECG tracings. Write down your ECG interpretation before checking the answers.

  • If there are significant differences between your answers and those given, discuss with a peer or supervisor.
With a supervisor

Review one of your cases of a presentation of cardiac failure with your supervisor.

  • Was the management gold-standard? Was the documentation adequate?
  • How would your supervisor’s approach differ from yours? Is there anything you might do differently next time?
  • Has an echocardiogram been done to classify the type of heart failure? Have medications that have a mortality benefit been introduced and up-titrated to maximum tolerated doses?

With your supervisor, discuss how you would approach a patient presenting with palpitations. Create and contrast differential diagnosis lists together, and then discuss management of these potential diagnoses.

  • What conditions are important not to miss, and how would you rule them out?
  • What are common pitfalls to avoid?

Discuss the local community’s cardiovascular health needs. Consider your location and access to services – the scope of general practice varies significantly throughout Australia.

  • Is there a way to involve the clinic in community preventive healthcare strategies?
  • Could you involve the school or town elders in health-promotion activities? How could you deliver health promotion messages in a way that would be well received by the local community?

Discuss potential causes of pericarditis or myocarditis and your diagnostic and management approaches.  

  • What are the key features on history?
  • What further investigations would you request on the patient’s initial presentation? What input from non-GP specialists would you require?
  • What if it was a paediatric presentation?
In a small group

Role-play using motivational interviewing to encourage a patient to change their lifestyle to improve their cardiovascular health, such as stopping smoking and increasing physical activity.

  • Give honest feedback to each other – did the ‘patient’ feel supported? Judged? Motivated? Anything else?
  • Reflect on this feedback and repeat the exercise in a few weeks.
  • How can you best empower your patients?

Run a teaching session for your peers (eg management of atrial fibrillation). Ask the learners to work through some cases at the end of the teaching session to evaluate whether the content has been understood clearly. Discuss different scenarios, such as ‘what if this was an elderly patient with a very high falls risk?’.

  • How did the learners go? Were they able to apply what they learnt from you?
  • What were the key points that you thought were important? Why? Is there anything you could do differently next time?

Have each person in the group present two cases related to cardiac conditions: one that went well, and one that was challenging.

  • Discuss the elements of the successful consultations – what will you try to replicate and practise? For the difficult consultations, troubleshoot how these could be done differently.

Practise explaining the evidence base for prescribing pharmacological treatment for cardiac conditions; for example, atrial fibrillation, peripheral vascular disease or heart failure with reduced ejection fraction. Explain as if to a colleague, and then to a patient.

  • Explain the same key information using technical jargon first, and then describe it in layperson terms for the ‘patient’. 
With a friend or family member

Do a role play where you explain to a patient why you are prescribing a medication, particularly for an asymptomatic condition, such as hypertension or hyperlipidaemia. Use a cardiovascular risk calculator. 

  • Ask your friend or family member for feedback – did they feel you included them in the consultation and decision-making? Did they understand your discussion of risk and why you are recommending this treatment?
  • Are there any resources or aids that could help you explain this?

Ask what your friend or family member knows about modifiable risk factors for heart disease. Where did that knowledge come from? Are there any barriers that prevent them from making positive lifestyle changes? Have they felt supported to make healthy lifestyle changes? What has been helpful, and what barriers have there been? 

  • Reflect on their answers – what elements could you incorporate into your own practice?
