Drug eluting stents as effective as vascular brachytherapy in preventing restenosis

After angioplasty is performed to widen clogged arteries, surgeons frequently use tiny wire-mesh tubes called stents to keep blood vessels open.
But despite stenting, scar tissue can form to create new blockages -- a process called in-stent restenosis (ISR). At present, vascular brachytherapy (catheter-based delivery of intracoronary radiation) is the only therapeutic modality proven to effectively reduce in-stent restenosis.
But a team of
Emory cardiology researchers presented a study at the American College of Cardiology (ACC) Scientific Sessions today showing that patients with ISR treated with a sirolimus-eluting stent (SES), which releases the therapeutic agent sirolimus over time to prevent restenosis, fared at least as well as those treated with vascular brachytherapy (VB).
Moreover, the patients who received the drug eluting stent had fewer cardiac events afterwards.
