In the current information age, patients want clarity about their diagnosis and prognosis. A patient who is being prepared for cardiac catheterization and possible percutaneous coronary intervention (PCI) wants to understand the risks and benefits of the procedure. Once they undergo PCI, they want to know whether the procedure was successful, if there were any complications, and if their risk for future events is lower than before PCI. When they are seen in follow-up, these same questions may arise, particularly about prognosis. How can clinicians answer these questions quantitatively? Cumulative survival probabilities post-PCI are readily available, but those do not accurately answer the patient’s question. Most studies do not take into account the prognosis based on survival to a certain time point and even fewer place those findings in the context of a demographically similar, external population.
