A heart attack (myocardial infarction or MI) is a serious medical emergency in which the supply of blood to the heart is suddenly blocked, usually by a blood clot.

A heart attack is a medical emergency. Call 999 and ask for an ambulance if you suspect a heart attack.

A lack of blood to the heart may seriously damage the heart muscle and can be life threatening.

Symptoms of a heart attack
Symptoms of a heart attack can include:

chest pain – a feeling of pressure, heaviness, tightness or squeezing across your chest
pain in other parts of the body – it can feel as if the pain is spreading from your chest to your arms (usually the left arm, but it can affect both arms), jaw, neck, back and tummy
feeling lightheaded or dizzy
sweating
shortness of breath
feeling sick (nausea) or being sick (vomiting)
an overwhelming feeling of anxiety (similar to a panic attack)
coughing or wheezing
The chest pain is often severe, but some people may only experience minor pain, similar to indigestion.

While the most common symptom in both men and women is chest pain, women are more likely to have other symptoms such as shortness of breath, feeling or being sick and back or jaw pain.

Call 999 immediately if you think someone might be having a heart attack. The faster you act, the better their chances.

Treating heart attacks
While waiting for an ambulance, it may help to chew and then swallow a tablet of aspirin (ideally 300mg), as long as the person having a heart attack is not allergic to aspirin.

Aspirin helps to thin the blood and improves blood flow to the heart.

In hospital, treatment for a heart attack depends on how serious it is.

The 2 main treatments are:

using medicines to dissolve blood clots
surgery to help restore blood to the heart
