Who might need PCI?

Dr. Najjar, you're going to explain to us what sort of patients end up having PCI or percutaneous coronary intervention or stenting as you called it for the heart arteries. Yeah, absolutely. It's a really important question. There are a lot of patients who are suitable to have percutaneous coronary intervention or PCI. Many patients can be divided into two main groups. Those patients who are having an acute heart attack and those patients who are entirely stable and have a condition called stable angina. So those Those having acute heart attack are patients who have severe pain, they have sweatiness and breathlessness, and they may have changes on their ECG, which is a test that gives us an idea of what the heart is doing. We may see changes on an echocardiogram, an ultrasound scan of the heart. And in that setting, opening up a heart artery as fast as possible will lead to an improvement of blood supply, stop the heart attack, and make those patients live longer. The second group of patients are those patients who have got a narrowing in their heart that is stable and isn't changing very much, but is causing them symptoms, and if there is a lack of blood supply, then those patients will find an improvement in the blood supply and often cases an improvement in their symptoms if we open their artery. So two main groups of patients, those with stable disease and those having acute heart attacks. Thank you very much.
