Heart Attack Symptoms & How to Treat a Heart Attack – First Aid Training – St John Ambulance


A heart attack happens when the supply of blood to the heart muscle is suddenly blocked usually by a blood clot. Lots of people make a full recovery, but there’s a serious risk that the heart might stop beating called a cardiac arrest. It’s vital that you help someone who is suffering a heart attack and call 999 or 112 for emergency help straight away. People who suffer from angina are at an increased risk of having a heart attack. Angina is chest pain, often described as a heaviness or a squeezing pain in the chest. The pain should ease within a few minutes if the person rests straight away and takes their angina medication. If the pain does not settle, it is safer to presume that it is a heart attack. If you think someone is having a heart attack, they may show some of the following signs. Pain in the chest, which could spread to the jaw, neck or arms. Breathlessness. Discomfort in the stomach similar to severe indigestion. Collapsing without warning. They may suddenly feel faint or dizzy. They may experience a feeling of impending doom. Pale skin, with blueness at the lips.They may have a rapid, weak or irregular pulse, sweating or be gasping for air. If you do come across someone with these symptoms call 999 or 112 immediately and say you think that they’re having a heart attack. After you have made the call, help move them into a comfortable position to help ease the strain on the heart. The best type of position is sitting on the floor with their head and shoulders supported and their knees bent. Place cushions behind them and under their knees. Then if you can and if they’re not allergic, give them an aspirin tablet 300mg and tell them to chew it slowly. Aspirin should not be given to someone under the age of 16. If they have angina medication you can help them to take it. Encourage them to rest. While you wait for help to arrive, monitor their breathing, pulse and level of response. Try to stay calm to avoid unnecessary stress. If they become unresponsive at any time, open their airway, check their breathing and be prepared to treat an unresponsive casualty. You may need to do CPR. So remember, if you think someone is having a heart attack, call 999 or 112 immediately. Help move them into a comfortable position and encourage them to rest. Give them 300mg of aspirin to chew and help them with their angina medication if they have some. While you wait for help keep checking their breathing, pulse and level of response. And that’s how you help someone who may be having a heart attack. If this video has been helpful to you, help support St John Ambulance, by going to sja.org.uk/donate
