When a patient arrives at the hospital with severe chest pain, doctors perform an electrocardiogram (ECG) to quickly detect a major heart attack.

If one is identified, the patient is usually rushed to the catheterisation lab where angioplasty and stenting are performed to reopen the blocked coronary artery – a procedure known as percutaneous coronary intervention (PCI).
