Heart attack - Symptoms 

Symptoms of a heart attack 

Heart attack: real story

Mike Smith has had three heart attacks. As he nears 60 and enjoys life to the full, he explains how the attacks affected him and how his recovery was different for each of them.

Advice for people with angina

Angina is a syndrome (a collection of symptoms caused by an underlying health condition) that is caused when the supply of oxygen-rich blood to the heart becomes restricted.

People with angina can experience similar symptoms to a heart attack, but they usually pass within a few minutes. However, occasionally people with angina can have a heart attack. It is important to be able to recognise the difference between the symptoms of angina and those of a heart attack.

The best way to do this is to remember that symptoms of angina can be controlled with medication, unlike the symptoms of a heart attack.

If you have angina, you may have been prescribed a medication called glyceryl trinitrate, which is used to provide short-term relief from the symptoms of angina. After taking this medication, your symptoms should improve within five minutes. If the first dose does not work, a second dose can be taken after five minutes, and a third dose after a further five minutes.

If the pain persists despite taking three doses of glyceryl trinitrate over 15 minutes, call 999 and ask for an ambulance.

Dial 999 immediately if you suspect that you or someone you know is having a heart attack.

The symptoms of a heart attack include:

  • chest pain: the pain is usually located in the centre of your chest and can feel like a sensation of pressure, tightness or squeezing
  • pain in other parts of the body: it can feel as if the pain is travelling from your chest to your arms (usually the left arm is affected but it can affect both arms), jaw, neck, back and abdomen
  • shortness of breath
  • nausea
  • an overwhelming sense of anxiety (similar to having a panic attack)
  • feeling light headed
  • coughing
  • vomiting
  • wheezing

The level of pain can vary significantly from person to person. For many people, the pain is severe and it has been described as feeling like ‘an elephant was sitting on my chest’. However, this is not always the case. For others, the pain can be minor and is similar to that experienced during indigestion. Also, some women and older people do not experience any chest pain at all.

It is not the level of chest pain that is important in determining whether you are having a heart attack. Instead, it is the overall pattern of symptoms that is important. 

The misconception that a heart attack always causes severe chest pain has led to many people dying needlessly. One American study found that a third of people who had a heart attack did not call an ambulance.

Do not worry if you have any doubts about whether your symptoms indicate that you are having a heart attack. Assume that you are having a heart attack and dial 999 to ask for an ambulance immediately.

Paramedics would much rather be called out to find out that an honest mistake has been made than be called out when it is too late to save a person’s life.

Waiting for the ambulance

If you know that you are not allergic to aspirin and aspirin is easily available, chew (do not swallow) an adult size tablet while you are waiting for the ambulance to arrive. The aspirin will help to thin your blood and restore the blood supply to your heart.
