Warning Signs of Heart Attack

Recognising the symptoms of a heart attack and calling 000 could save your life or the life of a loved one

If you, or someone you know, is experiencing  heart attack symptoms for longer than 10 minutes of rest, or if symptoms are severe, or they are getting worse, call 000 immediately. 

The most common heart attack warning signs are:  

Chest discomfort or chest pain (angina). This can feel like uncomfortable pressure, heaviness, squeezing, or pain in your chest. This discomfort can spread to your arms, neck, jaw or back.


Dizziness, light-headedness, feeling faint or feeling anxious. This may be associated with nausea or vomiting.

Shortness of breath or difficulty breathing.


Sweating and diaphoresis.   


If you are worried that you or someone is having a heart attack, tell someone. If symptoms are severe, or getting worse, or last

for more than 10 minutes, call 000 immediately

  • A heart attack  occurs when a heart artery gets blocked.

  • The most common sign of a heart attack is chest discomfort or pain, which can spread to your arms, neck, jaw or back.

  • Chest discomfort or pain can last for several minutes or come and go. 

  • A heart attack requires emergency treatment to restore blood flow to your heart. 

  • Always call 000 immediately if you suspect someone having a heart attack. 

How do you know if you’re having a heart attack?


Heart attack symptoms can be different in different people.


You may have just one, or a combination of the above mentioned symptoms. 


It may be chest pain, it may be shortness of breath, or it may be just sweating. 

The most typical feeling would be a heaviness or tightness across the chest. Often people describe it as an elephant sitting on their chest. This may be accompanied by sweating, palpitations, shortness of breath, dizziness, or even loss of consciousness.


Sometimes you may have no ‘warning signs’ at all.


If you have diabetes, you may even have a "silent" heart attack. 

The only way to know what you’re experiencing is to seek urgent help. Do not ignore the warning signs of a heart attack. Every second counts.
