RCVR (Residual CardioVascular Risk) Prospective Study

The goal of this observational study is to evaluate whether residual cardiovascular risk assessed at 1 month after percutaneous coronary intervention (PCI) is associated with long-term clinical outcomes in adult patients with coronary artery disease who are free from major adverse clinical events at 1 month after PCI. The main questions it aims to answer are: * Does residual cardiovascular risk at 1 month after PCI predict long-term net adverse clinical events? * Which components of residual cardiovascular risk are associated with subsequent adverse clinical outcomes? Participants will: * Undergo comprehensive laboratory testing at 1 month after PCI and annually thereafter. * Undergo artificial intelligence-based quantitative coronary angiographic analysis using DICOM datasets after PCI. * Be followed annually for up to 3 years after the 1-month assessment to evaluate clinical outcomes.
