Minutes matter - if you think you are having a heart attack, call 111 now.

Too many New Zealanders die or live with permanent disability because of the lack of awareness of heart attack warning signs and delays in seeking medical help. Even if you have had a heart attack, you may experience another - and next time, the symptoms can be different.

A heart attack may not be as dramatic as you think. If you're experiencing any of the following symptoms, you may be having a heart attack.

Are you experiencing... In any of these areas? You may also experience:
  • heaviness
  • tightness
  • pressure 
  • discomfort/pain
  • chest
  • shoulder
  • jaw
  • arm
  • neck
  • back
  • sweating
  • shortness of breath
  • nausea
  • fatigue
  • dizziness

If you think you are having a heart attack:

1. Stop and rest now

  • Tell someone how you feel.
  • If your symptoms are severe or they appear to be getting worse take action now.
  • Or if you take angina medication and the symptoms have not been relieved within 10 minutes then take action now.

2. Dial 111 immediately

  •  Ask for an ambulance, and if instructed and aspirin is available, chew one.

Minutes matter

Too many New Zealanders die or live with permanent disability through lack of awareness of heart attack signs and symptoms and delays in seeking medical help. Doctor Gerard Devlin, Medical Director, Heart Foundation and Doctor Tony Smith Medical Director of St John talk about warning signs and the importance of seeking medical attention if you think you are having a heart attack. If you have any of these symptoms longer than 10 minutes dial 111 now.

Is it possible to have another heart attack?

Women and heart attack warning signs

Women may experience any of the heart attack warning signs. However, they can sometimes experience heart attacks slightly differently to men:

  • the pain is more likely to spread as far as the shoulders, neck, abdomen and even the back
  • the pain may feel more like indigestion and not be consistent
  • there may not be pain but unexplained anxiety, nausea, dizziness, palpitations and cold sweat

Women may also experience unexplained tiredness prior to developing other heart attack symptoms.

'Silent' heart attacks and diabetes

People with diabetes can develop damage to their nerves (neuropathy). If the nerves supplying your heart are damaged, you may not feel the usual pain if your heart muscle becomes short of oxygen. If you're living with diabetes, you must rely on other warning signs such as:

  • shortness of breath
  • unexpected nausea
  • consistently high blood glucose levels that don't seem to have an explanation
