PCI Risk Calculator

This app predicts an individual’s risk of major complications after stent placement/PCI to support shared decision-making between care providers and patients, using statistical models developed with machine learning. When a person has one or more blocked arteries, physicians may choose to conduct a minimally invasive procedure called a percutaneous coronary intervention, or PCI. By inflating a balloon and potentially placing a stent, blood can flow more freely from the heart. While this carries fewer risks than open surgery, stenting and balloon angioplasty can result in complications like bleeding and kidney injury. The risks for patients undergoing PCI vary greatly depending on the individual patient, and both patients and clinicians have historically both over and underestimated the harms associated with PCI. Precise risk prediction is critical to treatment selection and the shared…
