HealthDay News — For patients with left main coronary artery disease (LMCAD), those with and without chronic kidney disease (CKD) undergoing revascularization have similar long-term outcomes with percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG), according to a study published in the August 14 issue of the Journal of the American College of Cardiology.

Gennaro Giustino, MD, from the Icahn School of Medicine at Mount Sinai in New York City, and colleagues examined the comparative effectiveness of PCI vs CABG surgery in 1869 patients with LMCAD and low or intermediate anatomical complexity according to baseline renal function.

The researchers found that 19.3% of patients had CKD. Compared to patients without CKD, those with CKD had higher 3-year rates of the primary end point (composite of death, myocardial infarction, or stroke [20.8 vs 13.5%; hazard ratio, 1.60]). Patients with CKD more commonly had acute renal failure (ARF) within 30 days compared to those without CKD (5.0 vs 0.8%); ARF was strongly linked to the three-year risk of death, stroke, or MI (50.7 vs 14.4%; hazard ratio, 4.59). In patients with and without CKD, ARF occurred less commonly after revascularization with PCI versus CABG (hazard ratios, 0.28 and 0.20, respectively). Patients with and without CKD had no significant differences in the rates of the primary composite end point after PCI and CABG.
