Evaluation of the Safety & Effectiveness of the PROMUS Element Everolimus-Eluting Coronary Stent System in patients with new or untreated atherosclerotic coronary artery lesions

This study is testing a heart stent — a small mesh tube placed inside a narrowed heart artery — called the PROMUS Element Everolimus-Eluting Coronary Stent, in patients with longer blockages (24 to 34 mm) in their heart arteries. Heart artery disease (coronary artery disease) can cause chest pain and heart attacks. A stent is placed during a procedure called PCI (percutaneous coronary intervention) to hold the artery open. This drug-eluting stent releases a medication called everolimus to prevent the artery from re-narrowing. The PLATINUM LL trial will follow patients for 12 months to assess safety and effectiveness. You may be eligible if: - You are 18 years of age or older - You have documented stable or unstable angina or silent ischaemia - You have a new (untreated) narrowing in a native coronary artery that is 24–34 mm long - Your heart pumping function is above 30% - You would be a candidate for bypass surgery if needed You may NOT be eligible if: - You have had a heart attack within 72 hours before the procedure with elevated cardiac enzymes - The target artery was treated with any intervention in the past 12 months - You are on chronic anticoagulation therapy - You are pregnant, nursing, or planning pregnancy within 12 months Talk to your doctor about whether this trial might be right for you.
