How common are heart attacks?
Around 80,000 people are admitted to hospital following a heart attack. The earlier someone seeks help if they suspect the are having a heart attack the better the prognosis. Currently the survival rate is about 7 in 10. If people called the emergency services earlier, it is estimated this would rise to 9 out of 10 people making a full recovery.
- Heart and circulatory disease, also known as cardiovascular disease, causes a quarter of all deaths in the UK and is the largest cause of premature mortality in deprived areas.
- Between April 2019 and March 2020 over 86,500 people had a heart attack (and were admitted to hospital) across England, Wales and Northern Ireland
Consequently the NHS are running a major campaign helping people recognise early signs and symptoms.
Signs and symptoms of a heart attack:
New NHS research shows that whilst 70% of those surveyed understood that pain in the chest is a symptom of a heart attack, just 41% knew sweating was a symptom and only 27% understood feeling weak, lightheaded or a feeling of general unease were also symptoms.
- Symptoms of a heart attack can include:
- chest pain – a sensation of pressure, heaviness, tightness or squeezing across the 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 is affected, but it can affect both arms), jaw, neck, back and tummy (abdomen)
- feeling lightheaded or dizzy
- shortness of breath
- feeling sick (nausea) or being sick (vomiting)
- an overwhelming sense of anxiety (similar to having a panic attack)
- coughing or wheezing
- Although the chest pain is often severe, some people may only experience minor pain, similar to indigestion. While the most common symptom of a heart attack in both men and women is chest pain, women are more likely to experience other symptoms such as shortness of breath, nausea/vomiting and back or jaw pain.
Post-menopausal women and people with Diabetes are less likely to experience chest pain.
What is the difference between a heart attack, cardiac arrest and angina?
A heart attack occurs when the supply of blood to the heart becomes blocked, which can starve it of oxygen potentially causing serious muscle damage. Whilst the early signs of a heart attack can vary, the most common include squeezing across the chest, sweating and a sense that something just isn’t right. The person will be conscious and breathing.
A cardiac arrest is different – it usually occurs suddenly and without warning with the person quickly losing consciousness. Their heart stops, they will have no pulse and sadly people experiencing a cardiac arrest will usually die within minutes if they do not receive treatment. A heart attack can lead to a cardiac arrest.
What’s a heart attack?
A heart attack is when one of the coronary arteries becomes blocked. The heart muscle is robbed of its vital blood supply and, if left untreated, will begin to die because it is not getting enough oxygen. If you are having a heart attack you will be conscious.
What’s cardiac arrest?
A cardiac arrest is when a person’s heart stops pumping blood around their body and they stop breathing normally. If your heart stops pumping blood around your body your brain becomes starved of oxygen causing you to become unconscious and stop breathing.
If someone is in cardiac arrest they will be unconscious and need to receive CPR immediately. They will also need you to use a defibrillator and call an ambulance to give them a chance of recovery.
What is angina?
Angina is discomfort caused by heart muscle complaining due to a reduced blood supply as blood tries to force its way through a narrowed artery.
How to help someone having a heart attack:
If you think someone might be having a Heart Attack, stay as calm as you can and encourage them to sit down. It will be easier for them to breathe if they remain upright and so you should support them in a comfortable position. Placing something under their knees can help their circulation.
If they have been prescribed a GTN spray, they should use this now (spray it under their tongue) and if they are suffering an angina attack (rather than a heart attack) this should help. GTN helps to dilate the blood vessels surrounding the heart to improve the flow to the muscles.
If the GTN does not help and they have been prescribed a 300mg Aspirin tablet, they should chew this.
Remain calm and reassuring around the casualty, but phone for an ambulance and if there is a defibrillator available get it now and discretely have it ready to use immediately if they lose consciousness and stop breathing.
A heart attack can lead to a cardiac arrest.
If they become unconscious and not breathing, phone an ambulance and start CPR – pushing hard and fast on the centre of the casualty’s chest – see the flow chart below. Deploy the defibrillator as soon as possible.
In the UK alone, there are over 30,000 Cardiac arrests occurring outside of hospital each year. Studies have shown that if someone has a Cardiac Arrest in the Community with no defibrillator immediately available, there is only a 6% chance of them surviving; even if someone is performing great CPR on them. However, if a defibrillator is used within the first 3 minutes of someone stopping breathing, their chances of survival jumps from 6% to a staggering 74% with a 10% reduction in survival rate for every minute of delay.
Automatic, External Defibrillators (AED) are now widely available; located at many train and tube stations, shopping centres, dentists and GP Practices, sports grounds, leisure centres and offices. However, people do not always know where to find them and are often scared to deploy them – Read our article on common myths about defibrillators
The Karolinska Institute in Sweden are currently tested a drone which could deliver defibrillators to the scene of a casualty having a cardiac arrest. They can also remotely talk people through how to use them. Their research suggests that these drones could arrive at a destination up to four times faster than an ambulance, saving valuable time and increasing their chance of survival.
If you have a defibrillator available; open it up and it will start talking to you. Dry the casualty’s chest and position the pads as illustrated on the pads themselves. Ideally someone should be doing CPR whilst another person is putting the pads onto the casualty’s chest and concentrating on the defibrillator. Keep going (listen to and observe the prompts from the machine) and do not stop until the paramedic is there and ready to take over or the casualty begins to regain consciousness.
