Despite the established clinical efficacy following intravascular imaging (IVI)-guided percutaneous coronary intervention (PCI) than angiography-guided PCI, evidence regarding prognostic benefits of IVI-guided PCI in acute myocardial infarction (AMI) patients with high thrombus burden remains limited. Using the nationwide registries of KAMIR-NIH and KAMIR-V, we evaluated the prognostic impact of IVI-guided PCI in AMI patients with high thrombus burden. A total of 4,074 patients with AMI and TIMI thrombus grades 4 or 5 who underwent aspiration thrombectomy were selected, of whom 892 patients (21.

Background: Although patients with high bleeding risk (HBR) often have complex coronary artery lesions, it is not known whether intravascular imaging-guided percutaneous coronary intervention (PCI) improves their prognosis. We sought to investigate the benefit of intravascular imaging-guided PCI for complex coronary artery lesions in patients with HBR.
Methods: This was a secondary analysis of the RENOVATE-COMPLEX-PCI trial (Randomized Controlled Trial of Intravascular Imaging Guidance Versus Angiography-Guidance on Clinical Outcomes After Complex Percutaneous Coronary Intervention) in which patients with complex coronary artery lesions undergoing PCI were enrolled at 20 sites in Korea from May 2018 through May 2021.
Background: Although potent P2Y inhibitors, such as ticagrelor and prasugrel, are standard treatment in patients with acute myocardial infarction (AMI), evidence for their efficacy and safety compared with clopidogrel is limited in patients with AMI complicated by cardiogenic shock.
Methods: Among 28,949 patients from the nationwide pooled registry of KAMIR-NIH and KAMIR-V, a total of 1482 patients (5.1%) with AMI and cardiogenic shock who underwent percutaneous coronary intervention of the culprit vessel were selected.

Background: Sarcopenia is an aging-related condition characterized by loss of skeletal muscle mass and is an indicator of subclinical atherosclerosis. The relationship between reduced muscle mass and long-term clinical outcomes in patients with advanced coronary artery disease who have undergone coronary artery bypass grafting (CABG) is not fully understood. This study is sought to evaluate the prognostic implications of sarcopenia screening in patients undergoing CABG.

Introduction And Objectives: There are no clinical data on the efficacy of intravascular imaging-guided percutaneous coronary intervention (PCI) compared with angiography-guided PCI in patients with acute myocardial infarction (AMI) and cardiogenic shock. The current study sought to evaluate the impact of intravascular imaging-guided PCI in patients with AMI and cardiogenic shock.
Methods: Among a total of 28 732 patients from the nationwide pooled registry of KAMIR-NIH (November, 2011 to December, 2015) and KAMIR-V (January, 2016 to June, 2020), we selected a total of 1833 patients (6.
