Hishikari K, Hikita H, Yoshikawa H, et al. - Researchers examined the link between lipoprotein (a) concentrations and clinical results following percutaneous coronary intervention (PCI) for stable angina pectoris (SAP) in hemodialysis (HD) patients. This analysis involved 410 consecutive HD patients who received successful PCI for SAP, and had serum lipoprotein (a) levels recorded on admission. Two groups of patients were defined: low and high group exhibiting lipoprotein (a) level < 40 mg/dL (n = 297) and ≧ 40 mg/dL (n = 113) respectively. Experts assessed the incidence of major adverse cardiac event (MACE) post-PCI. In Cox analysis, high lipoprotein (a) level was identified as an independent predictor for MACE following PCI. In this study, a higher incidence of MACE post-PCI was observed in relation to high lipoprotein (a) level among HD patients who underwent PCI for SAP.
