What Is A Heart Attack?
What is typically termed, ‘heart attack’, can actually fall under one of two distinct conditions. A heart attack occurs when blood flow to part of the heart is blocked, causing heart muscle damage, but the heart typically continues beating. Sudden cardiac arrest is when the heart abruptly stops beating altogether, immediately cutting off blood flow to the brain and other vital organs, requiring immediate CPR and defibrillation.
Heart attacks in the workplace are serious medical emergencies that require immediate recognition and response. Knowing the signs and symptoms of a heart attack and having proper protocols in place can mean the difference between life and death.
This comprehensive guide covers how to identify cardiac emergencies in the workplace, the appropriate first aid responses, and the steps organisations should take to create heart-safe work environments through proper first aid training, equipment, and emergency planning
The Critical Need For Immediate First Aid Response
Cardiac emergencies can happen anywhere, including the workplace, where people spend a significant portion of their time. Each year, approximately 57,000 Australians suffer a heart attack, and many of these occur during work hours. When a colleague experiences a heart attack, the actions taken in the first few minutes are crucial to their survival and recovery.
The frightening reality is that without immediate intervention, the survival rate for cardiac emergencies drops by about 10% for every minute that passes. However, with prompt recognition of symptoms, quick emergency response, and proper first aid techniques, many lives can be saved.
Don’t leave your workplace safety to chance. Enrol your team in a nationally recognised first aid course with First Aid Workplace Training to ensure everyone has the skills to respond effectively to cardiac emergencies. Our hands-on training provides practical skills that save lives when seconds count.
Understanding Heart Attacks
A heart attack, or myocardial infarction, occurs when blood flow to a part of the heart muscle is blocked, usually by a blood clot. If the blockage isn’t quickly treated, the affected heart muscle begins to die due to lack of oxygen.
It’s important to distinguish between a heart attack and cardiac arrest, as they require different responses:
- Heart Attack: The heart continues beating but blood flow to part of the heart is blocked
- Cardiac Arrest: The heart suddenly stops beating altogether
Risk factors for heart attacks in Australian adults include:
- Lifestyle factors: Smoking, poor diet, excessive alcohol consumption, and lack of physical activity
- Health conditions: High blood pressure, high cholesterol, diabetes, and obesity
- Demographic factors: Age, family history, and Aboriginal and Torres Strait Islander heritage
The Royal Australian College of General Practitioners notes that Australians have one of the highest rates of obesity globally, with 67% of adults being overweight or obese, significantly increasing heart attack risk in the workplace.
Quick response to a heart attack is critical because time equals heart muscle. The longer treatment is delayed, the more damage occurs to the heart. According to health authorities, a significant percentage of the damage from a heart attack occurs in the first hour, emphasising why workplace readiness is essential.
Common Signs and Symptoms
Recognising the warning signs of a heart attack quickly can save a colleague’s life. While chest pain is the most well-known symptom, heart attacks can present in various ways.
Classic Heart Attack Warning Signs
- Chest discomfort: Often described as pressure, tightness, heaviness, or pain in the centre of the chest. It may feel like a squeezing sensation or uncomfortable pressure that lasts more than a few minutes or comes and goes.
- Shortness of breath: This may occur with or without chest discomfort and can feel like being unable to catch one’s breath.
- Pain that radiates: Discomfort or pain that spreads to the shoulders, arms (particularly the left arm), neck, jaw, or back.
Gender Differences in Symptoms
The Heart Foundation of Australia highlights important differences in how heart attacks may present in women compared to men:
- Women are more likely to experience “atypical” symptoms such as fatigue, nausea, and back or jaw pain
- Women may have symptoms for several weeks before a major heart attack
- Women’s symptoms are sometimes dismissed as anxiety or stress
- Women themselves may downplay symptoms or attribute them to other causes
Warning Signs Often Dismissed
Many heart attacks in Australian workplaces go unrecognised because symptoms are attributed to:
- Indigestion or heartburn
- Muscle strain from physical work
- Stress or anxiety in high-pressure job environments
- Normal ageing discomfort
- Simple exhaustion from overwork
Unfortunately, many Australians who have experienced a heart attack initially dismissed their symptoms as something less serious, delaying crucial treatment.
Immediate Response Protocol
When a colleague shows potential heart attack symptoms, follow these critical steps:
- Recognise the emergency: If someone complains of chest pain or exhibits other heart attack symptoms, take it seriously immediately.
- Call Triple Zero (000): Call emergency services right away. Don’t wait to see if symptoms improve. Inform the operator that you suspect a heart attack.
- Help position the person: Have them sit or lie down in a comfortable position with their head and shoulders supported and knees bent. Loosen tight clothing.
- Provide aspirin if available and appropriate: If the person is not allergic to aspirin and local workplace protocols allow, provide a single dose (usually 300mg) to be chewed (not swallowed whole).
- Monitor vital signs: Check breathing and pulse. Be prepared to start CPR if the person becomes unresponsive and is not breathing normally.
- Retrieve the workplace AED: Send someone to get the Automated External Defibrillator if available.
- Communicate crucial information to emergency responders: Include when symptoms started, what the person was doing when they began, medical history if known, and any actions already taken.
Global health authorities such as the American Heart Association and the Australian Resuscitation Council emphasise that early recognition and response can double or even triple positive outcomes. In the workplace, where colleagues may notice subtle changes in each other’s appearance or behaviour, early warning signs can be spotted more readily than when someone is alone.

First Aid Training for Cardiac Emergencies
Proper first aid training is essential for effectively responding to cardiac emergencies in the workplace. All Australian workplaces should have staff trained in these critical skills:
Basic First Aid for Suspected Heart Attacks
- Keep the person calm and reassured
- Maintain a seated or semi-reclined position
- Monitor and record vital signs until emergency services arrive
- Know your workplace first aid kit contents and how to use them
- Document all observations and actions taken
CPR Essentials
According to the Australian Resuscitation Council guidelines:
- Push hard and fast in the centre of the chest (approximately 100-120 compressions per minute)
- Allow complete chest recoil between compressions
- Minimise interruptions to compressions
- Use the correct hand position (centre of chest, between nipples)
- For untrained responders, hands-only CPR is recommended
- For trained responders, use a 30:2 compression-to-ventilation ratio
Automated External Defibrillator (AED) Use
It is also recommended that:
- AEDs should be easily accessible in all workplaces
- Staff should be familiar with their location
- Basic training in AED use should be provided to all employees
- AEDs are designed to be used by anyone, even without training
- The device provides voice prompts to guide users
- Early defibrillation can increase survival rates by up to 70%
Regular Skill Refreshers
Safe Work Australia recommends:
- CPR certification skills should be refreshed every 12 months
- General first aid certifications should be renewed every 3 years
- Regular workplace drills to practice emergency response
- Updates whenever workplace layout or staffing changes significantly
Creating a Heart-Safe Workplace
Developing a comprehensive cardiac emergency response system requires even more than just training. Here’s how Australian workplaces can create heart-safe environments:
Developing a Cardiac Emergency Response Plan
- Create written protocols for various cardiac emergency scenarios
- Assign clear roles and responsibilities to staff members
- Establish communication chains and backup systems
- Ensure the plan complies with Work Health and Safety (WHS) regulations
- Review and update the plan annually
Strategic Placement of AEDs
- Install AEDs in central, easily accessible locations
- Ideally, an AED should be reachable within 3 minutes from any point in the workplace
- For larger worksites, multiple AEDs may be necessary
- Consider environmental factors that may affect AED performance
- Implement a regular maintenance schedule
Signage and Accessibility
- Use standardised AED signage that complies with Australian Standards
- Ensure emergency response information is visible throughout the workplace
- Create clear maps showing first aid equipment locations
- Make provisions for staff with disabilities in emergency planning
- Use multilingual signage if appropriate for your workforce
Regular Emergency Drills
- Schedule unannounced cardiac emergency drills
- Rotate roles so all staff gain experience in different aspects of emergency response
- Debrief after drills to identify areas for improvement
- Document participation and outcomes
- Involve local emergency services occasionally for more realistic scenarios
Designating and Training First Responders
- Identify staff members strategically located throughout the workplace
- Provide enhanced training for these designated responders
- Ensure coverage across all shifts and departments
- Create a system to identify trained responders quickly (e.g., special lanyards)
- Consider incentives for staff who maintain advanced certifications.
Legal Requirements and Considerations
Australian workplaces have specific legal obligations regarding first aid and emergency response and failure to meet these requirements can result in significant penalties, but more importantly, may cost lives in an emergency situation –
Prevention Strategies
Creating a workplace that promotes heart health can reduce the risk of cardiac emergencies:
Stress Management Techniques
- Reasonable workloads and adequate staffing
- Clear communication about expectations
- Flexible work arrangements when possible
- Support for work-life balance
- Access to employee assistance programs
Heart-Healthy Work Environment
- Nutritious options in cafeterias and vending machines

Frequently Asked Questions
What are the common heart attack symptoms to look for in the workplace?
Common heart attack symptoms include pain or discomfort in the centre or left side of the chest, feelings of discomfort that may feel like uncomfortable pressure or fullness, shortness of breath, sweating, nausea, and lightheadedness. Symptoms vary from person to person, so it’s important to be aware of these signs.
What should I do if I suspect someone is having a heart attack?
If you suspect someone is having a heart attack, it is crucial to call 000 immediately. While waiting for help to arrive, make the person comfortable and encourage them to remain calm. If they are conscious, you can also have them chew an aspirin unless they are allergic.
What are the risk factors associated with heart disease?
Risk factors for heart disease include high blood pressure, high cholesterol, smoking, obesity, diabetes, a sedentary lifestyle, and a family history of heart conditions. Managing these risk factors is essential to prevent a heart attack.
How can I prevent a heart attack in the workplace?
To prevent a heart attack, maintain a healthy lifestyle by eating a balanced diet, exercising regularly, managing stress, avoiding tobacco, and keeping regular health check-ups. It’s also important to recognise risk factors and seek medical advice if you are at risk of heart disease.
What is the difference between heart attack symptoms and stroke symptoms?
While heart attack symptoms often include chest pain and discomfort, stroke symptoms can include sudden confusion, trouble speaking, weakness or numbness on one side of the body, and difficulty walking. It’s important to recognise these symptoms early and call 000 for immediate medical assistance.
How does coronary heart disease relate to heart attacks?
Coronary heart disease is a condition where the arteries supplying blood to the heart become narrowed or blocked due to plaque buildup. This can reduce blood flow to the heart and increase the risk of a heart attack, as the heart may not receive adequate oxygen and nutrients.
How is a heart attack treated once diagnosed?
Treatment for a heart attack may include medications such as antiplatelets, thrombolytics, and beta-blockers, as well as medical procedures like angioplasty or coronary artery bypass grafting (CABG) to restore blood flow to the heart. The specific treatment depends on the severity of the heart condition.
