What are the early warning signs?
Yes, there can be early warning signs of a heart attack, although they are not always obvious. Some people have mild symptoms days or even weeks before the main event. Others have little or no warning at all.
The most common signs include chest discomfort, breathlessness, and feeling unusually tired. You might also notice pain that spreads to the arm, jaw, back, or stomach. These symptoms can come and go or feel different from one person to another.
Symptoms that can happen before a heart attack
Chest pain or pressure is one of the best-known warning signs. It may feel like tightness, heaviness, squeezing, or indigestion. Some people describe it as a discomfort rather than severe pain.
Shortness of breath can also appear before a heart attack, especially during activity or when resting. You may feel light-headed, sweaty, or sick. A sudden feeling of anxiety or “something not being right” can sometimes happen too.
Warning signs that are easy to miss
In the UK, many people do not realise that tiredness can be an early sign, especially in women. You may feel drained for no clear reason or notice that everyday tasks suddenly become harder. This can be a warning if it is new and unusual for you.
Other subtle signs include nausea, indigestion, or pain in the upper stomach. Some people get pain in the neck, shoulder, arm, or jaw without strong chest pain. These symptoms can be mistaken for something less serious.
When symptoms are more urgent
If chest pain lasts more than a few minutes, gets worse, or keeps returning, treat it as an emergency. The same applies if the pain spreads to the arm, back, neck, or jaw. Do not wait to see if it passes.
Call 999 straight away if you think someone may be having a heart attack. Do not drive yourself to hospital if you can avoid it. An ambulance can start treatment sooner and get you to the right place safely.
What to do if you notice warning signs
Stop what you are doing and rest if you develop possible heart attack symptoms. If you are not allergic to aspirin and have been told it is safe for you, emergency services may advise taking one while waiting for help. Follow the 999 operator’s instructions carefully.
It is always better to get checked, even if symptoms turn out not to be a heart attack. Fast action can save heart muscle and reduce the risk of serious complications. If in doubt, call 999.
