Cardiovascular (CV) assessment in prerenal transplant patients varies by center. Current guidelines recommend stress testing for candidates if ≥ 3 CV risk factors exist. We evaluated the CV assessment and management in 685 patients referred for kidney transplant over a 7-year period. All patients had CV risk factors, and the most common cause of end-stage renal disease was diabetes. Thirty-three percent (n = 229) underwent coronary angiography. The sensitivity of stress testing to detect obstructive coronary artery disease (CAD) was poor (0.26). Patients who had no CAD, nonobstructive CAD, or CAD with intervention had significantly higher event-free survival compared with patients with obstructive CAD without intervention. There were no adverse clinical events (death, myocardial infarction, stroke, revascularization, and graft failure) within 30 days post-transplant in patients who had preoperative angiography (n = 77). Of the transplanted patients who did not have an angiogram (n = 289), there were 8 clinical events (6 myocardial infarctions) in the first 30 days. In conclusion, our results indicate that stress testing and usual risk factors were poor predictors of obstructive CAD and that revascularization may prove beneficial in these patients.
肾移植术前患者的心血管(CV)评估因中心而异。目前的指南建议,如果存在≥3个CV危险因素,应对候选者进行负荷试验。我们评估了7年间685例转诊接受肾移植患者的CV评估和管理情况。所有患者均有CV危险因素,终末期肾病最常见的病因是糖尿病。33%(n = 229)的患者接受了冠状动脉造影。负荷试验检测阻塞性冠状动脉疾病(CAD)的敏感性较差(0.26)。与未接受干预的阻塞性CAD患者相比,无CAD、非阻塞性CAD或接受干预的CAD患者的无事件生存率显著更高。术前进行血管造影的患者(n = 77)在移植后30天内未发生不良临床事件(死亡、心肌梗死、中风、血运重建和移植失败)。在未进行血管造影的移植患者(n = 289)中,前30天内有8例临床事件(6例心肌梗死)。总之,我们的结果表明,负荷试验和常见危险因素对阻塞性CAD的预测能力较差,血运重建可能对这些患者有益。
