Starting Out With Heart Attack Symptoms
Heart Attack Symptoms: the few things that matter most, and the mistakes that catch people out early.
The warning signs of a myocardial infarction, including the ones that are not textbook.
Key takeaways
- Call 999 if pain lasts: more than 15 minutes, or is severe
- Typical description: pressure, tightness, heaviness or squeezing
- Most useful single change: Call 999 rather than arranging your own transport.
- Commonest mistake: Driving yourself or being driven to hospital.
- See a doctor if any of the signs under "When to speak to a doctor" below apply to you.
Why bother
Delay is the largest determinant of damage, and atypical presentation is a major cause of delay in women, older adults and people with diabetes.
Start here
Start with two. Add the rest once those have stopped taking effort.
- Call 999 rather than arranging your own transport
- Sit down and stay calm while waiting
Then add these
Once the basics are in place, add these.
- Chew 300mg aspirin if the operator advises it and you are not allergic
- Learn CPR; survival depends heavily on bystanders

How this page was put together
Every figure, recommendation and warning above is taken from the guidance named in Where this comes from. Nothing on this page is inferred, summarised or generalised beyond what those bodies publish: where they give a number, it is their number, and where they are silent, so are we. Pages are rebuilt whenever the underlying record changes. Sign-off by a named clinician, where it has happened, is shown at the top of the page along with the date.

Always speak to a GP, pharmacist or another qualified health professional before making changes that affect your treatment, and never delay seeking medical advice because of something you have read here. In an emergency, call 999.
