Key Takeaways – Common Heart Problems & First Aid Response

• Heart disease is Australia’s leading cause of death, with many fatalities preventable through early diagnosis and treatment.

• Heart attacks occur when blood flow to the heart is blocked, often by fatty deposits, causing oxygen deprivation and heart muscle damage.

• Major heart attack risk factors include smoking, high blood pressure, poor diet, obesity, diabetes, and family history of cardiovascular events.

• Typical heart attack symptoms range from chest pain or tightness to shortness of breath, nausea, and dizziness—sometimes without chest pain, especially in women.

• Immediate first aid for suspected heart attack: Call 000/112, keep casualty calm, give 300mg aspirin (if not allergic), and be ready to perform CPR.

• Angina is chest discomfort caused by reduced blood flow during physical or emotional stress, usually relieved by rest or prescribed medication.

• Seek urgent help if angina symptoms last more than 10–15 minutes, as this may indicate a heart attack.

• Cardiac arrest is when the heart suddenly stops pumping, often due to abnormal rhythms like ventricular fibrillation, requiring immediate CPR and defibrillation.

• Key difference: Heart attack is a circulation problem; cardiac arrest is an electrical problem, though one can lead to the other.

• First aid training can save lives—learning CPR and the chain of survival equips you to act quickly in cardiac emergencies.

Common Heart Problems in Australia

Heart disease is the leading cause of death in Australia, but many fatalities can be prevented through awareness, early diagnosis, treatment, and timely first aid. This article explores common heart problems in Australia, their prevalence, symptoms, risk factors, and first aid responses. We’ll also highlight the importance of first aid training so that you can act confidently in an emergency.
Did you know that heart problems are the leading cause of death in Australia? And that many of these deaths could be prevented with early diagnosis and treatment. This blog post will look closely at some of Australia’s most common heart problems and how they can be treated. We’ll also discuss some first-aid tips everyone can use during an emergency.

What Is Cardiovascular Disease in Australia

Cardiovascular disease (CVD) is an umbrella term for conditions affecting the heart and blood vessels, including coronary heart disease, heart failure, arrhythmias, and stroke.

Prevalence & Impact in Australia

According to the Australian Bureau of Statistics (2022), about 5.2% of Australians (1.3 million people) live with CVD. The Heart Foundation reports that around one in six Australians (4.5 million) live with some form of cardiovascular condition, making it one of the most prevalent heart conditions in Australia. Heart disease contributes to thousands of deaths annually and remains a leading cause of hospitalisation.

Heart Attack

A heart attack is a cardiovascular event caused by the sudden death of heart muscle cells. The most common cause is a blockage of the coronary arteries (arteries that supply the heart with blood) either by thrombus or, less commonly, spasms.

Due to this sudden loss of perfusion, the cells become starved of oxygen, which causes the heart to stop functioning normally or altogether.

Risk Factors include:

• Fatty deposits on the artery walls (atherosclerosis)
• Smoking
• High blood pressure / Hypertension
• Poor diet
• Obesity
• Lack of Exercise
• Age
• Diabetes
• A positive family history of first-degree relatives with cardiovascular events at a relatively young age (< 60)

• Common Types of Heart Problems

  Coronary Heart Disease & Angina

  Coronary heart disease occurs when the arteries supplying blood to the heart narrow due to fatty deposits (atherosclerosis). This narrowing reduces oxygen supply, especially during exertion, leading to angina.

  Angina Symptoms:

  • Chest discomfort or tightness
  • Pain radiating to the neck, jaw, or arms
  • Often triggered by stress or exercise
  • Typically relieved by rest or prescribed medication (e.g., nitro-glycerine)

  If angina lasts longer than 10–15 minutes, it may signal a heart attack and urgent medical care is required.

  The Heart Foundation reports around 57,000 heart attacks each year, equating to roughly 19 deaths per day from coronary events.

  Heart Attack (Myocardial Infarction)

  A heart attack occurs when blood flow to the heart is blocked, depriving the heart muscle of oxygen.

  Risk Factors:

  • Atherosclerosis
  • Smoking
  • High blood pressure
  • Poor diet, obesity, lack of exercise
  • Diabetes
  • Family history of cardiovascular events

  Heart Attack Symptoms Australia:

  • Central chest pain or tightness radiating to shoulders, arms, or jaw
  • Shortness of breath, dizziness, or nausea
  • Sweating and pale, cool skin
  • Loss of consciousness in severe cases

  Not all heart attacks present with chest pain. A silent heart attack may show only vague symptoms such as fatigue, breathlessness, or indigestion-like discomfort. Studies suggest one in five heart attacks may be silent.

  First Aid Steps:

  1. Call 000 / 112 immediately
  2. Keep casualty calm and seated
  3. Give 300 mg aspirin if not allergic
  4. Be ready to perform CPR if casualty becomes unresponsive

  Learning to recognise heart attack Australia signs early is critical for survival.

  Arrhythmias (e.g. Atrial Fibrillation)

  Arrhythmias are irregular heart rhythms that can cause the heart to beat too fast, too slow, or irregularly. The most common is atrial fibrillation (AFib).

  AFib Australia Statistics:

  • Prevalence is rising significantly with age
  • Associated with a five-fold increased risk of stroke
  • Responsible for nearly 20% of ischaemic strokes in Australia (Heart Foundation)

  Arrhythmia Symptoms:

  • Palpitations (racing or fluttering heartbeat)
  • Fatigue
  • Dizziness or fainting
  • Shortness of breath

  Treatment often involves medication, lifestyle changes, or procedures to restore normal rhythm.

  Heart Failure

  Heart failure (also known as congestive heart failure, CHF) occurs when the heart cannot pump blood efficiently.

  Heart Failure Australia Stats:

  • Over 144,000 Australians (~0.6%) live with heart failure
  • Risk doubles with high blood pressure, obesity, and diabetes

  CHF Symptoms Australia:

  • Shortness of breath (especially when lying down)
  • Swollen ankles, feet, or abdomen
  • Fatigue and weakness
  • Persistent coughing or wheezing

  Heart failure requires long-term management with medication, lifestyle changes, and regular check-ups.

Treatment:

• Call 000 / 112 immediately and ask for an ambulance
• Follow the instructions of the ambulance call taker/operator, who will advise you on what to do
• Encourage the casualty to stop what they are doing
• Sit the casualty down and make them comfortable
• Provide reassurance and stay calm
• Remove clothing that potentially inhibits breathing
• Give dissolvable aspirin 300mg (usually one tablet)
  o Withhold if the casualty is known to be anaphylactic to aspirin
• Ensure good access to fresh air
• Monitor DRS ABCD, and if you have undergone CPR training, be prepared to start CPR if the casualty becomes unconscious and stops breathing.

Note: The routine administration of oxygen in persons with a suspected heart attack is not advised. 

Angina

Angina is a symptom of myocardial ischemia, which means that the heart muscles receive inadequate blood flow and, hence, inadequate oxygen for the heart’s work at a particular time.

This is due to a disease of the coronary arteries called atherosclerosis (fatty deposits causing hardening and narrowing of the artery lumen). At rest, a casualty will have no symptoms. Although the arteries are narrowed, the heart does not require a lot of blood at rest anyway. Angina occurs during physical or emotional excitement when the heart starts beating faster, requiring more oxygen.

Signs and Symptoms:

• The same as heart attack symptoms, although generally not as severe
• Symptoms will subside when the heart slows down or the casualty takes any medications prescribed for their angina
• The casualty may tell you that they know they have angina

Treatment:

• Stop exercise / physical exertion. Advise the casualty to relax
• Keep casualty calm
• Assist casualties in taking any medication they have been prescribed by their doctor (normally Anginine, nitro-glycerine tablets or spray)
• Monitor DRS ABCD, which can be learned through a first aid course
• If pain persists for more than 10-15 minutes, call 000 / 112 (as this could be a sign of a heart attack)

Cardiac Arrest

Cardiac arrest is the cessation of adequate blood circulation due to the sudden loss of normal heart function.

Note that a heart attack and a cardiac arrest are not the same. Heart attacks are caused by a blockage that stops blood flow to the heart and, at times, may cause a cardiac arrest.

Cardiac arrest is caused when the heart’s electrical system malfunctions and stops working properly, often resulting in death. This may be caused by abnormal or irregular heart rhythms (called arrhythmias).

A common arrhythmia in cardiac arrest is ventricular fibrillation – refer to the image.

Cardiac arrest is a medical emergency and requires an immediate response.

Signs and Symptoms:

• May occur without prior warning
• A slow or racing heartbeat
• Fainting, dizziness, blackouts
• Fatigue
• Chest pain
• Shortness of breath, weakness
• Nausea and vomiting

Key Risk Factors in Australia

Several modifiable and non-modifiable risk factors increase the likelihood of developing common heart problems Australia:

• High blood pressure & cholesterol – leading contributors to heart disease
• Smoking – causes around 15,500 deaths annually in Australia
• Poor diet, obesity, diabetes, and inactivity – major lifestyle factors
• Age & gender differences – men face higher risk earlier, while women’s risk rises post-menopause
• Indigenous and rural Australians – face higher prevalence due to healthcare access and social determinants

 

Prevention & When to Seek Help

Preventing types of heart disease Australia involves lifestyle modifications and regular health checks:

• Maintain a healthy weight through balanced diet and exercise
• Quit smoking and reduce alcohol consumption
• Manage blood pressure and cholesterol
• Use Medicare-covered heart health checks for early detection

Women-specific risks

Hormonal changes during menopause increase risk, and women may experience atypical heart attack symptoms, such as nausea or fatigue instead of chest pain.

Call 000 immediately if you notice persistent chest discomfort, sudden shortness of breath, or fainting.

Knowing first aid for cardiac emergencies and recognising red flags could save a life.

How CPR First Aid Courses Can Help

Being prepared with the right knowledge and skills can make the difference between life and death. A CPR First Aid course equips you with the ability to perform CPR, manage an AED, and provide first aid for cardiac emergencies.

We also offer AED training so you can confidently use defibrillators, which are crucial in cases of sudden cardiac arrest.

FAQ (Schema-Ready)

Is heart disease common in younger Australians?

While heart disease is more prevalent in older populations, risk factors like obesity, diabetes, and smoking are leading to more diagnoses among younger Australians.

Can CPR help in heart attack?

Yes. If a heart attack progresses to cardiac arrest, immediate CPR and defibrillation provide the best chance of survival.

What is the difference between a heart attack and cardiac arrest?

A heart attack is a circulation issue caused by blocked blood flow, while cardiac arrest is an electrical problem where the heart suddenly stops beating.
