Percutaneous Coronary Intervention in Patients with End-Stage Renal Disease

Abstract

Patients with end-stage renal disease (ESRD) represent a growing number of patients in the cardiac catheterization laboratories worldwide. This is a consequence of the growing absolute number of ESRD patients in developed countries, better noninvasive diagnostic tools, better catheterization facilities and last-but-not-least better education of referring physicians about the incidence and prognosis of coronary artery disease (CAD) for patients with ESRD. There is growing evidence of the positive impact of coronary revascularization on long-term outcome of these patients. ESRD patients have a high comorbidity and are therefore better candidates for the less invasive approach using percutaneous coronary intervention (PCI) rather than coronary artery bypass surgery (CABG). From the view of the interventional cardiologist, ESRD patients represent one of the most challenging patient cohort concerning technical challenges and potential risk of complication for the patient. Percutaneous coronary intervention (PCI) including debulking techniques and stent implantation is the current standard therapy for patients with symptomatic single-vessel disease (SVD) and the preferred therapy for most patients with focal, polyfocal or even diffuse multi-vessel disease (MVD). Coronary bypass surgery is reserved for a decreasing number of patients with mechanically untreatable coronary lesions and unprotected left main stem stenosis. The problem of restenosis and subsequent target lesion revascularization has been decreased to a minimum by the use of drug-eluting stents (DES), even though prospective randomized trials including ESRD patients are lacking. In case of acute coronary syndromes, the need for immediate coronary angiography and subsequent revascularization by means of PCI should be pointed out.
