What tests are used to diagnose a heart attack?
To diagnose a heart attack:
- An electrocardiogram (EKG) can show the extent and location of heart muscle damage.
- Blood tests measure enzyme levels that show heart muscle damage. This helps a doctor figure out when the attack started.
- An echocardiogram is an ultrasound that can show how the heart is pumping, what areas might not be pumping well, and if any parts of the heart are damaged.
- Cardiac catheterization (angiogram) uses X-rays to find out how much the coronary arteries are blocked.
