Background: Limited information is available about clinical outcomes following routine percutaneous coronary intervention (PCI) in the current era. This study aimed to identify predictors of adverse clinical or angiographic complications following PCI in patients from many different countries., Methods: RIVIERA is a multinational, prospective, observational study in patients undergoing elective or primary PCI. Consecutive patients (n=7962) were enrolled in 144 hospitals from 23 countries in four different continents. Primary outcome was death or myocardial infarction (MI). The mean age of the patients was 59 years and 77% were men; 92% of patients underwent elective and 8% primary PCI., Results: The rate of in-hospital outcomes was low: death 0.3%, MI 1%, any bleeding 3.4%. Angiographic complications occurred in 8.7% of patients, mainly coronary dissection (3.7%) and no reflow (2%). After multivariable analysis, the strongest independent predictors of death or MI were clinical presentation with non-ST-segment elevation acute coronary syndrome or ST-segment elevation myocardial infarction and administration of a glycoprotein (GP) IIb/IIIa inhibitor. Radial access, thienopyridine pretreatment and anticoagulation with enoxaparin were associated with a lower risk of death or MI. Female gender, PCI of coronary artery bypass graft, administration of a GP IIb/IIIa inhibitor and combined use of enoxaparin and unfractionated heparin were significantly associated with more bleeding. Radial access was the only variable associated with less bleeding., Conclusions: Routine PCI appears to be a relatively safe revascularization procedure. Many of the variables identified as predictors of adverse cardiac outcomes confirm results obtained in recent randomized PCI trials and are modifiable, suggesting that further improvements can be made.

Objective: This post-marketing surveillance registry is aimed at determining the safety and reliability of the CYPHER Select Sirolimus-eluting stent (SES) in routine clinical practice., Background: Little information and angiographic follow-up data in large-scale "real world" registry is available for the CYPHER Select SES, an advanced-generation SES., Methods: This was a prospective multicenter (20 centers) registry. 1189 consecutive patients who received at least 1 CYPHER Select SES during daily clinical practice were enrolled. Patients who underwent emergency stenting for acute myocardial infarction were excluded., Results: The procedure's success rate was 98.3% for CYPHER Select SES implantation, and follow-up rates were 98% with 100% data auditing. Target lesion revascularization (TLR) at 12 months occurred in 60 (5.14%) cases, cardiac death in 13 cases (1.11%), Q wave myocardial infarction (MI) in 5 cases (0.43%), non-Q-MI in 9 cases (0.77%), target vessel revascularization (TVR) in 67 cases (5.74%), and MACE defined as cardiac death, nonfatal MI and TLR in 76 cases (6.51%). MACE-free survival rate at 12 months was 93.7%. Angiographic follow-up at 9 months was performed in 418 (68.3%) lesions treated by CYPHER Select SES. The binary restenosis rate was 4.8% in-stent and 9.6% in-segment. Subgroup analysis showed diabetes, bifurcation lesion and combined use of different stents were independent risk factors of cumulative MACE. In-segment MLD
