Coronary chronic total occlusion (CTO) is a common type of lesion in patients with coronary artery disease, and percutaneous coronary intervention (PCI) serves as one of the primary treatment methods for CTO patients [Traditionally, PCI for non-occlusive disease was considered a low-risk procedure for patients with stable coronary artery disease. A national audit of over 100,000 PCIs conducted annually reported early Q-wave MI, emergency CABG, cerebrovascular accident, and mortality rates at 0.03%, 0.02%, 0.04%, and 0.14%, respectively36. However, significant advancements in coronary intervention equipment now allow successful revascularization of a broad range of CTO lesions using advanced techniques. Performing CTO interventions safely requires specialized training and education in centers committed to achieving a high level of success for these challenging procedures [When performing interventions in hospitalized patients with CTO, various nursing-related challenges arise [Therefore, this study aims to evaluate the application of checklist-based nursing care for patients undergoing CTO interventions by analyzing various indicators, including the duration of care, patient anxiety levels, improved patient satisfaction, and occurrence of adverse events.
