How do I know if I’m having a heart attack?
Would you know what to do in the event of a heart attack?
A heart attack happens when there is sudden loss of blood flow to your heart muscle. It can be life threatening. If you suspect you or someone else is suffering a heart attack, call 999 immediately.
Many of us also confuse a heart attack with cardiac arrest. Discover how to spot the difference, and how you could save a life with our video on how to perform CPR.
What are the signs of a heart attack?
Although they vary from person to person, common signs of a heart attack include:
Chest pain or discomfort – a sudden tightness or feeling of pressure in the centre of the chest. Pain levels can range from mild to severe
Pain in other parts of the body – it can feel as if pain is travelling from your chest to your arms (although the left is more usually affected), neck, jaw, back or stomach
Sweatiness – a cold, clammy feeling
Nausea or vomiting
Indigestion, or heartburn-type pain. This is very often ignored in the hope that it will pass
Shortness of breath
Coughing or wheezing
Unusual fatigue, exceptional tiredness
Women are more likely to experience a heart attack without chest pain, so need to pay special attention to the other, ‘silent’ symptoms too. These silent symptoms include fatigue and indigestion-type pain. Women are also more likely to delay seeking medical attention and treatment.
People with diabetes may not feel the classic chest pain as they may have some nerve damage as a result of their condition. If you're concerned, seek medical advice.
If you are worried that you may be having a heart attack, call 999 immediately.
What is the difference between a heart attack and cardiac arrest?
Some people confuse a heart attack with cardiac arrest – however, these are not the same thing. A heart attack can come before cardiac arrest. A person who goes into cardiac arrest may experience heart attack-like symptoms such as chest pain or dizziness beforehand. With these similarities, discover how to tell the difference...
What are the signs of cardiac arrest?
Common signs and symptoms of cardiac arrest:
They appear not to be breathing
They’re not moving
They don’t respond to any stimulation, such as being touched or spoken to
If someone is in cardiac arrest, you should perform CPR until an ambulance arrives. Learn how to perform CPR in our video, made with the experts at Benenden Hospital
Recent studies have shown that women who have cardiac arrests are more likely to die than men. This could be because they are less likely to be given CPR by a bystander, or because people assume women are less likely to experience cardiac arrest.
If you are worried that someone has gone into cardiac arrest, it is important to call 999 immediately and perform CPR until the ambulance arrives.
