Is there a test to see if you had a heart attack?
Tests to diagnose a heart attack include: Electrocardiogram (ECG). This first test done to diagnose a heart attack records electrical signals as they travel through your heart. Sticky patches (electrodes) are attached to your chest and limbs.
What blood tests detect heart problems?
The most common types of blood tests used to assess heart conditions are:
- Cardiac enzyme tests (including troponin tests) – these help diagnose or exclude a heart attack.
- Full blood count (FBC) – this measures different types of blood levels and can show, for example, if there is an infection or if you have anaemia.
