Clinical results from the Rabin Medical Center in Israel have showed a correlation between the use of drug-eluting stents and an improvement in long-term results for patients undergoing angioplasties.

Randomized clinical trials have determined that drug-eluting stents decrease the incidence of restenosis and the need for corrective revascularization procedures.  The study examined the benefits and risks of using drug-eluting stents over bare-metal stents.

Results from the study showed that the use of drug-eluting stents reduced the occurrence of heart attack by almost 0.7% and decreased the need for a revascularization procedure by over 2.5%.  Overall patient mortality also decreased by almost 2.7%.
