Appraising the impact of left ventricular ejection fraction on outcomes of percutaneous drug-eluting stenting for unprotected left main disease: insights from a multicenter registry of 975 patients.

Background: Despite the well-known prognostic impact of systolic dysfunction in unselected patients undergoing percutaneous coronary intervention (PCI), limited data are available on its current predictive role after PCI for unprotected left main disease (ULM). We thus appraised the prognostic role of left ventricular ejection fraction (LVEF) in patients undergoing PCI for ULM with drug-eluting stents (DES).

Methods: Consecutive eligible subjects were retrospectively enrolled in a national registry.

Sex-related differences in patients undergoing percutaneous unprotected left main stenting.

Aims: Percutaneous coronary intervention (PCI) is increasingly being used for unprotected left main (ULM) disease. Limited data are available on sex-related differences in this setting. We investigated gender-associated differences in patients undergoing stent-based PCI for ULM.

Impact of acute coronary syndromes on two-year clinical outcomes in patients with unprotected left main coronary artery stenosis treated with drug-eluting stents.

In this study we investigated the impact of acute coronary syndromes (ACSs) on clinical outcomes in patients with unprotected left main coronary artery (ULMCA) stenosis treated with drug-eluting stents (DESs). In this multicenter, retrospective, observational study we enrolled 1,101 patients with ULMCA stenosis treated with DESs. Six hundred eleven patients presented with ACS and 490 had stable coronary artery disease.

Impact of bifurcation technique on 2-year clinical outcomes in 773 patients with distal unprotected left main coronary artery stenosis treated with drug-eluting stents.

Background: Distal unprotected left main coronary artery (ULMCA) stenosis represents a technical challenge for interventional cardiologists. In this study, we compared 2-year clinical outcomes of different stenting strategies in patients with distal ULMCA stenosis treated with drug-eluting stents.

Methods And Results: The survey promoted by the Italian Society of Invasive Cardiology on ULMCA stenosis was an observational study on patients with ULMCA stenosis treated with percutaneous coronary intervention.

Ostial and midshaft lesions vs. bifurcation lesions in 1111 patients with unprotected left main coronary artery stenosis treated with drug-eluting stents: results of the survey from the Italian Society of Invasive Cardiology.

Aims: In this study, we compared the cumulative risk of major adverse cardiac events (MACE) of patients with distal unprotected left main coronary artery (ULMCA) stenosis with those of patients with ostial and midshaft lesions treated with drug-eluting stent (DES).

Methods And Results: The survey promoted by the Italian Society of Invasive Cardiology on ULMCA stenosis was an observational study involving 19 high-volume Italian centres. We enrolled 1111 patients with ULMCA stenosis treated with DES.

Temporal pattern of ischemic events in relation to dual antiplatelet therapy in patients with unprotected left main coronary artery stenosis undergoing percutaneous coronary intervention.

Objectives: The aim of this study was to investigate whether there is a temporal pattern of ischemic events in relation to dual antiplatelet therapy in patients with unprotected left main coronary artery (ULMCA) stenosis treated with percutaneous coronary intervention (PCI).

Background: Identifying which periods during follow-up of patients with ULMCA stenosis treated with PCI are associated with higher risk of clinical events might help to improve therapeutic strategies.

Methods: We analyzed data from 15 centers involved in an observational study conducted by the Italian Society of Invasive Cardiology on patients with ULMCA stenosis treated with PCI.

Long-term clinical benefit of drug-eluting stents over bare-metal stents in diabetic patients with de novo left main coronary artery disease: results from a real-world multicenter registry.

Background: Few data are available on diabetic patients undergoing percutaneous coronary intervention (PCI) in the context of unprotected left main coronary artery (ULMCA) disease. The main goal of this study was to present the long-term relative benefits of using drug-eluting stent (DES) instead of bare-metal stent (BMS) for diabetic patients submitted to percutaneous ULMCA treatment in a large real world multicenter registry.

Methods: The GISE-SICI registry is a retrospective, observational multicenter registry promoted by the Italian Society of Invasive Cardiology in which 19 high-volume participating centers enrolled 1,453 consecutive patients who underwent PCI on ULMCA between January 2002 and December 2006.

Comparison of drug-eluting stents and bare-metal stents for the treatment of unprotected left main coronary artery disease in acute coronary syndromes.

The aim of this study was to compare long term clinical outcome after left main stenting in a large real world population of patients treated with drug-eluting stents (DES) or bare-metal stents (BMS) in the setting of acute coronary syndromes. The advent of DES decreased the risk of unprotected left main coronary artery restenosis as compared with BMS, but safety concerns still exist, especially when high-risk patients presenting with acute coronary syndromes are considered. The Gruppo Italiano Studi Emodinamici-Societa' Italiana di Cardiologia Invasiva (GISE-SICI) registry is a retrospective, observational multicenter registry promoted by the Italian Society of Invasive Cardiology in which 19 high-volume participating centers enrolled 1,453 consecutive patients who underwent percutaneous coronary intervention on unprotected left main coronary artery between January 2002 and December 2006.

Two-year clinical outcome with drug-eluting stents versus bare-metal stents in a real-world registry of unprotected left main coronary artery stenosis from the Italian Society of Invasive Cardiology.

Data are limited about the relative efficacy of drug-eluting stents (DESs) versus bare-metal stents (BMSs) for the treatment of unprotected left main coronary artery (ULMCA) stenosis. The survey promoted by the Italian Society of Invasive Cardiology on ULMCA stenosis was an observational study involving 19 high-volume Italian centers of patients with ULMCA stenosis treated using percutaneous coronary intervention (PCI). From January 2002 to December 2006, of 1,453 patients identified with ULMCA stenosis treated with PCI, 1,111 were treated with DESs and 342 were treated with BMSs.
