Occult renal disease in patients undergoing coronary artery bypass grafting: does it really matter?

Invited Editorial

In this prospective randomised study titled “Impact of occult renal disease on the outcomes of off-pump and on-pump coronary artery bypass grafting” published later in this issue [1], the authors have tried to examine if the strategy of myocardial revascularization, off-pump (OPCAB) or conventional on-pump coronary artery bypass grafting (CABG), determines the post-operative outcomes in patients with occult renal disease. To answer this question, the authors have randomised 120 patients into off-pump (n = 62) and on-pump (n = 58) CABG. While there are previous studies where outcomes have been compared between OPCAB and conventional on-pump CABG, not many have examined this question in the specific subset of occult renal disease and perhaps none have looked at this subset in a randomised trial setting. This study, which is adequately powered and is well conducted, explores an area where there is a relative paucity of information. Broadly, the authors conclude that there is no...
