What does PCI stand for in ACLS protocol?

In the context of ACLS (Advanced Cardiovascular Life Support) protocol, PCI stands for Percutaneous Coronary Intervention. It is a non-surgical procedure used to treat narrowing of the coronary arteries of the heart found in coronary artery disease. PCI typically involves the use of a catheter to place a stent to open up blocked arteries, improving blood flow to the heart. This intervention can be critical in the management of patients experiencing acute coronary syndromes.
