Heart Failure
Heart Failure - symptoms, causes, treatment options available in Australia, and when to see a doctor.
What You Need to Know - The Basics
Heart failure is when your heart isn't pumping blood as well as it should.
The main things to know:
- You might feel very tired and short of breath.
- It's more common in older people and those with other heart problems.
- Heart failure is serious but can be treated with medicine and lifestyle changes.
- Swelling in your legs, ankles, or feet can be a sign of heart failure.
When to see a doctor immediately: If you have sudden shortness of breath, chest pain, or fainting.
Doctors can help manage heart failure, so you can feel better and stay active.
Overview
Heart failure is a medical condition that affects your body in specific ways.
How it works in your body (pathophysiology):
Heart failure affects your body through specific biological processes:
- Structural and functional changes: Problems like myocardial infarction (heart attack), hypertension (high blood pressure), and cardiomyopathy (heart muscle disease) can change the heart's structure and function. These changes lead to less blood being pumped out (reduced cardiac output) and higher pressure inside the heart.
- Symptoms: These changes cause symptoms like shortness of breath (dyspnoea), tiredness (fatigue), and fluid build-up.
- Types of heart failure:
- HFrEF (Heart failure with reduced ejection fraction): The heart muscle is weak and can't squeeze well.
- HFpEF (Heart failure with preserved ejection fraction): The heart muscle is stiff and can't relax properly.
- Cellular and molecular pathways: Both types involve complex interactions in the body, including:
- Neurohormonal activation: This is when certain hormones and nerves become more active, affecting the heart.
- Inflammatory processes: Inflammation (swelling and irritation) can worsen heart failure.
- Complications: These processes can lead to other problems like irregular heartbeats (arrhythmias) and kidney issues (renal dysfunction).
Statistics and Prevalence in Australia
Did you know? About 144,000 of Australians are affected by this condition.
In Australia, heart failure is a significant public health concern.
According to the Australian Bureau of Statistics (ABS) National Health Survey, approximately 144,000 Australians aged 18 and over (0.7%) were living with heart failure in 2022.
However, systematic reviews suggest the actual how common it is may be between 1.0% and 2.0% due to underdiagnosis and limitations of self-reported data [1][2].
Demographically, heart failure predominantly affects older Australians, with nearly three-quarters (103,000) of those affected being aged 65 and over.
The condition is more prevalent in men (97,700, 1.0%) compared to women (49,400, 0.5%) [1].
Indigenous Australians experience a 1.7 times higher age-standardised how common it is rate of heart failure than non-Indigenous Australians, highlighting significant health disparities [2].
Symptoms and Clinical Presentation
This condition can show up in different ways, and symptoms may vary between people.
Common symptoms:
- Symptoms can be mild at first but may get worse over time
- Each person may experience different combinations of symptoms
- Symptoms can come and go or be constant
Early warning signs:
- Subtle changes that may be the first signs of the condition
- Symptoms that might be easy to miss or ignore
Serious warning signs that need immediate medical attention:
- Severe symptoms that could indicate complications
- Any symptoms that get suddenly worse
- Signs that suggest you need urgent medical care
Important: If you're unsure about your symptoms, it's always better to see a doctor for proper evaluation.
Heart failure presents with a spectrum of symptoms that can vary in severity.
Early signs include exertional dyspnoea, fatigue, and peripheral oedema.
As the condition progresses, symptoms may worsen, leading to orthopnoea, paroxysmal nocturnal dyspnoea, and significant fluid retention [3].
Atypical presentations can occur, particularly in older adults and those with comorbid conditions, where symptoms may be subtle or attributed to other illnesses.
Red flag symptoms requiring immediate medical attention include severe breathlessness, chest pain, syncope, and rapid weight gain due to fluid accumulation [3].
Causes and Risk Factors
This condition happens for several reasons working together. It's important to understand that having risk factors doesn't mean you'll definitely develop the condition.
Main causes:
- The exact cause may not be fully understood
- Multiple factors usually work together
- Both genetic and environmental factors can play a role
Risk factors you can't change:
- Your age and gender
- Family history and genetics
- Previous medical conditions
Risk factors you can influence:
- Lifestyle choices
- Environmental exposures
- Health management decisions
Good news: Understanding these risk factors can help with prevention and early detection.
Heart failure results from various causes, often involving a combination of genetic, environmental, and lifestyle factors.
Common causes include coronary artery disease, hypertension, and valvular heart disease.
Risk factors such as obesity, diabetes, smoking, and sedentary lifestyle contribute to the development and progression of heart failure [4].
The how it works in the body involves complex interactions between myocardial injury, neurohormonal activation, and systemic inflammation, leading to cardiac remodelling and dysfunction.
Understanding these mechanisms is crucial for effective management and prevention strategies [4].
Diagnosis
Getting the right diagnosis is important for proper treatment. Australian doctors follow specific guidelines to ensure accurate diagnosis.
How doctors diagnose this condition:
- They ask detailed questions about your symptoms and medical history
- They do a physical examination
- They may order specific tests if needed
- They use established medical guidelines and criteria
Tests that might be needed:
- Blood tests to check for specific markers
- Imaging studies like X-rays or scans if appropriate
- Specialist tests depending on your symptoms
Why accurate diagnosis matters: The sooner doctors can diagnose the condition correctly, the faster they can start the right treatment for you.
The diagnosis of heart failure in Australia follows guidelines from the National Heart Foundation of Australia and the Cardiac Society of Australia and New Zealand.
A thorough clinical check-up, including history taking and physical examination, is essential.
Key diagnostic tools include echocardiography to assess ejection fraction and B-type natriuretic peptide (BNP) tests to support the diagnosis [5][6].
Imaging studies such as chest X-rays and advanced modalities like cardiac MRI may be utilised to evaluate cardiac structure and function.
Differential diagnosis considerations are crucial to exclude other conditions with similar presentations, such as chronic obstructive pulmonary disease or renal failure [5].
Treatment Options in Australia
Treatment for this condition in Australia follows evidence-based guidelines and is tailored to each person's needs.
Treatment approaches available:
- First-line treatments: Usually tried first and often most effective
- Medications: Various medicines that can help manage symptoms
- Non-medicine treatments: Therapies and lifestyle changes that can help
- Specialist treatments: More advanced options for complex cases
Good news about costs in Australia:
- Medicare covers many consultations and treatments
- The Pharmaceutical Benefits Scheme (PBS) makes many medications more affordable
- Public healthcare provides access to essential treatments
Treatment planning: Your healthcare team will work with you to create a treatment plan that suits your specific needs and circumstances.
Treatment of heart failure in Australia is guided by evidence-based protocols that include medicine and non-medicine strategies.
First-line medicine treatments involve the use of ACE inhibitors, beta-blockers, and diuretics to manage symptoms and improve outcomes.
For patients with HFrEF, additional medications such as mineralocorticoid receptor antagonists and angiotensin receptor-neprilysin inhibitors may be prescribed [6].
Non-medicine interventions include lifestyle modifications such as dietary changes, regular physical activity, and smoking cessation.
In severe cases, surgical options like heart transplantation or mechanical circulatory support may be considered [6].
The Medicare Benefits Schedule and the Pharmaceutical Benefits Scheme provide financial support for diagnostic tests and medications, ensuring accessibility to essential treatments for Australians [6].
