What is the impact of renal dysfunction on outcomes of coronary artery bypass surgery?
Studies have shown that there is an increased risk of adverse outcomes for patients with renal dysfunction undergoing coronary artery bypass surgery compared to those with normal renal function. This has been demonstrated in the VA Cooperative Study #5 (Anderson et al, 1999), the Society of Thoracic Surgeons National Adult Cardiac Database (Cooper et al, 2006), and the Bypass Angioplasty Revascularization Investigation (Szczech et al, 2002). These studies have shown that patients with impaired renal function had a higher risk of mortality, stroke, and major adverse cardiac events.
