A heart attack is a medical emergency. Symptoms can vary between people, and some presentations may be less typical, so sudden or unusual symptoms should not be dismissed.
Possible warning signs
- Pressure, tightness or discomfort in the centre of the chest.
- Discomfort spreading to an arm, shoulder, jaw, neck or back.
- Shortness of breath.
- Nausea, light-headedness or a cold sweat.
- Unusual weakness or symptoms without prominent chest pain, particularly in some women, older adults and people with diabetes.
WHO’s September 2026 heart-attack guidance emphasizes that early recognition and rapid emergency care can improve survival and recovery. Read the WHO heart-attack fact sheet.
Prevention still matters
Not using tobacco, staying active, eating a balanced diet and managing blood pressure, glucose and lipids can help reduce cardiovascular risk.

Emergency note: If you suspect a heart attack, seek your local emergency medical service immediately rather than waiting for symptoms to pass.
