Chest x-ray
An x-ray of the chest is useful for detecting:
- lung disorders (e.g. chest infections)
- signs of heart disease.
If you are having heart surgery, a chest x-ray will routinely be performed beforehand, and is often referred to during surgery.
Blood test
Before heart surgery, a doctor or nurse will take blood samples – about 30 ml is required.
