Researchers have found that drug-eluting stents are safe to use in older patients, regardless of a patient’s kidney function.
In the largest registry study to date that suggests that drug-eluting stents appear to be safe in older patients with varying levels of chronic kidney disease undergoing percutaneous coronary interventions (PCIs).

Patients with chronic kidney disease undergoing percutaneous coronary intervention had less mortality and revascularization events if the stent they received was drug-eluting as opposed to bare-metal.

Overall adverse outcomes were higher for patients with chronic kidney disease, especially severe and on dialysis, than for those with normal renal function and that stented patients were not compared with those treated with medical therapy alone.
Drug-eluting stents reduce incidences of death, MI and revascularization in the patients with normal renal function.
