Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to compare the effectiveness and safety of intracoronary stenting with or without abciximab, an anti-platelet therapy, and conventional coronary angioplasty with abciximab in patients undergoing percutaneous coronary intervention.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a multicenter, randomized, double-blind, placebo-controlled study evaluating the safety and effectiveness of intracoronary stenting with or without abciximab, an anti-platelet therapy, and conventional coronary angioplasty with abciximab in patients undergoing percutaneous coronary intervention. Patients will be randomly assigned to one of three treatment groups: coronary angioplasty plus abciximab, intracoronary stent plus abciximab, or intracoronary stent plus placebo. The primary measures of effectiveness will be a 30-day composite, clinical outcome as determined by the number of deaths, myocardial infarctions, or urgent repeat revascularizations. Please see attached results.

Patients will receive one of three different treatments: Coronary angioplasty plus abciximab; Intracoronary stent plus abciximab; or Intracoronary stent plus placebo.
