The aim of this study was to examine racial differences in long-term survival among hemodialysis patients after coronary artery bypass grafting (CABG). To our knowledge this has not been previously addressed in the literature. Black and white hemodialysis patients undergoing first-time, isolated CABG procedures between 1992 and 2011 were compared. Survival probabilities were computed using the Kaplan-Meier product-limit method and stratified by race. Hazard ratios (HR) and 95% confidence intervals (CI) were computed using a Cox regression model. A total of 207 (2%) patients were on hemodialysis at the time of CABG. White (n = 80) hemodialysis patients had significantly decreased 5-year survival compared with black (n = 127) patients (adjusted HR = 1.9, 95% CI = 1.2-2.8). Our finding provides useful outcome information for surgeons, primary care providers, and their patients.
本研究旨在探讨血液透析患者冠状动脉旁路移植术后（CABG）长期生存的种族差异。据我们所知，这在文献中尚未得到解决。比较了 1992 年至 2011 年间接受首次孤立性 CABG 手术的黑人和白人血液透析患者。使用 Kaplan-Meier 乘积限法计算生存概率，并按种族分层。使用 Cox 回归模型计算危险比（HR）和 95%置信区间（CI）。共有 207 名（2%）患者在 CABG 时接受血液透析。与黑人（n = 127）患者相比，白人（n = 80）血液透析患者的 5 年生存率显著降低（调整后的 HR = 1.9，95%CI = 1.2-2.8）。我们的发现为外科医生、初级保健提供者及其患者提供了有用的预后信息。
