Estimating percutaneous coronary intervention (PCI) mortality risk by a clinical prediction model is imperative to help physicians, patients and family members make informed clinical decisions and optimize participation in the consent process, reducing anxiety and improving quality of care. At a healthcare system level, risk prediction scores are essential to measure and benchmark performance. We aimed to assess the accuracy of the simple, contemporary and well-designed Toronto PCI mortality risk score in ICP-BR registry, the first Brazilian PCI multicenter registry with follow-up information.
