When comparing the two types of stents, investigators found an equivalent MACE rate at 30 days (3.9 percent vs. 5.9 percent, p=0.12) with sirolimus-eluting and bare-metal stents. However, at eight months, the MACE rate was significantly lower with drug-eluting stents (7.8 percent vs. 14.5 percent, p=0.0039). This difference was mainly driven by a 69 percent reduction in the need for a repeat procedure to reopen the treated coronary artery (3.2 percent with sirolimus-eluting stents vs. 10.2 percent with bare-metal stents, p=0.0004). The rates of death and repeat heart attack were similar, as was the incidence of stent thrombosis.
"Our study shows that tirofiban is 'noninferior' in its efficacy to abciximab in this high-risk patient population, and has a better safety profile," said Dr. Valgimigli. "We have also confirmed that, even in STEMI patients, drug-eluting stents are highly effective in reducing reintervention in the target vessel. More important, this came without an extra price to pay in terms of death, myocardial infarction or stent thrombosis."
Dr. Valgimigli will present the results of this study on Sunday, March 30 at 9:00 a.m. CDT in the Grand Ballroom, S100. This study will simultaneously publish in JAMA: Journal of the American Medical Association.
