Coronary artery disease is common in patients with end-stage renal failure (ESRF). However, there is little evidence that revascularisation improves outcomes, compared with medical management. This study assessed survival and cardiovascular outcomes in patients with ESRF undergoing coronary angiography and then having coronary artery bypass graft (CABG) surgery, percutaneous coronary intervention (PCI) or medical management.Survival and major adverse cardiac events (MACE) were examined in all patients with ESRF who underwent coronary angiography at Auckland City Hospital between 2003 and 2012. Outcomes of patients who underwent revascularisation (CABG or PCI) were compared with those managed medically.Two hundred and eighty-eight patients with ESRF had a total of 382 diagnostic coronary angiograms. Ninety-one (32%) patients underwent revascularisation (61 PCI, 30 CABG), with the other 197 (68%) treated medically or requiring no specific cardiac treatment. The median survival was 3.3 (IQR 2.1-5.3) years in patients undergoing CABG, 2.9 (IQR 1.5-5.4) years in patients treated with PCI and 2.9 (IQR 1.3-5.5) years in patients managed medically. There was no significant difference in survival between treatment modalities in the entire cohort, nor in the 108 patients with triple vessel disease. Similarly, there was no difference in the incidence of major adverse cardiac events, comparing medical management with revascularisation.There was no apparent survival advantage with revascularisation by either CABG or PCI, compared with medical management, in patients with ESRF undergoing coronary angiography. This study confirms the poor prognosis of patients with ESRF and coronary disease. Observational studies cannot control for all potential confounders; randomised trial data are needed to guide optimal management of this high-risk patient cohort. |
