Abstract

Calcified nodules (CNs) are associated with poor prognosis after percutaneous coronary intervention (PCI) and have been reported to occur more frequently in hemodialysis patients. However, their prognosis in hemodialysis patients undergoing PCI has not been fully elucidated. We aimed to investigate the prognosis of hemodialysis patients who underwent PCI for CNs using intravascular ultrasound (IVUS) and/or optical coherence tomography (OCT)/optical frequency domain imaging (OFDI). About 141 hemodialysis patients who underwent PCI between January 2020 and December 2021 were analyzed retrospectively in a single center. CNs are defined as heavily calcified plaques that protruding into lumen in a convex shape. MACE (a composite of cardiovascular death, target lesion related myocardial infarction, and target lesion revascularization) between CNs and Non-CNs at 1 year were compared. In the entire study population, the mean age was 69.3 ± 10.7 years, and 94 (77.0%) were male. At 1 year, the incidence of MACE following PCI was significantly higher in the CNs group (39.2% vs 9.9%, log-rank p <0.001), particularly for cardiovascular death (17.7% vs 4.2%, log-rank p = 0.009). After multivariate analysis adjusting for demographic characteristics, CNs remained independently associated with increased risk of MACE (adjusted hazard ratio: 4.93, 95% confidence interval 2.07 to 11.76; p <0.001). CNs were associated with a higher incidence of MACE and a higher cardiovascular death rate in hemodialysis patients who underwent PCI.

期刊介绍： Published 24 times a year, The American Journal of Cardiology® is an independent journal designed for cardiovascular disease specialists and internists with a subspecialty in cardiology throughout the world. AJC is an independent, scientific, peer-reviewed journal of original articles that focus on the practical, clinical approach to the diagnosis and treatment of cardiovascular disease. AJC has one of the fastest acceptance to publication times in Cardiology. Features report on systemic hypertension, methodology, drugs, pacing, arrhythmia, preventive cardiology, congestive heart failure, valvular heart disease, congenital heart disease, and cardiomyopathy. Also included are editorials, readers'' comments, and symposia.
