Twelve-year outcomes after revascularization for ostial/shaft lesions in unprotected left main coronary artery.

Objective: To evaluate a very long-term clinical outcomes of patients treated with coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) with drug-eluting stents (DES) for ostial/shaft lesions in unprotected left main coronary artery (ULMCA).

Methods & Results: A total of 472 patients with isolated ostial/shaft lesions in ULMCA were enrolled, who received DES implantation or underwent CABG between January 2003 and July 2009 in Beijing Anzhen Hospital. The major endpoints of this study were death, repeat revascularization, non-procedural myocardial infarction (MI) and stroke.

Left ventricular systolic dysfunction in patients with unprotected left main coronary artery disease.

Background: The optimal coronary revascularization strategy for patients with unprotected left main coronary artery (ULMCA) disease and left ventricular systolic dysfunction (LVSD) remains uncertain. The purpose of this study was to evaluate the clinical outcomes after percutaneous coronary intervention (PCI) with a drug-eluting stent (DES) versus coronary artery bypass grafting (CABG) in patients with ULMCA disease with or without LVSD.

Methods: A total of 984 patients with ULMCA disease who received a DES (n = 511) or underwent CABG (n = 473) were included in this study.

Growth differentiation factor-15 is a prognostic marker in patients with intermediate coronary artery disease.

Background: Growth differentiation factor-15 (GDF-15) is involved in multiple processes that are associated with coronary artery disease (CAD). However, little is known about the association between GDF-15 and the future ischemic events in patients with intermediate CAD. This study was conducted to investigate whether plasma GDF-15 constituted risk biomarkers for future cardiovascular events in patients with intermediate CAD.

Long-term outcomes of PCI CABG for ostial/midshaft lesions in unprotected left main coronary artery.

Background: There are limited data on long-term (> 5 years) outcomes of drug-eluting stent (DES) implantation compared with coronary artery bypass grafting (CABG) for ostial/midshaft left main coronary artery (LMCA) lesions.

Methods: Of the 259 consecutive patients in Beijing Anzhen Hospital with ostial/midshaft LMCA lesions, 149 were treated with percutaneous coronary intervention (PCI) with DES and 110 were with CABG. The endpoints of the study were death, repeat revascularization, myocardial infarction (MI), stroke, the composite of cardiac death, and major adverse cardiac and cerebrovascular events (MACCE, the composite of cardiac death, MI, stroke or repeat revascularization).

Very Long-term Outcomes and Predictors of Percutaneous Coronary Intervention with Drug-eluting Stents Versus Coronary Artery Bypass Grafting for Patients with Unprotected Left Main Coronary Artery Disease.

Background: There are limited data on longer-term outcomes (>5 years) for patients with unprotected left main coronary artery (ULMCA) disease who underwent percutaneous coronary intervention (PCI) in the drug-eluting stents (DES) era. This study aimed at comparing the long-term (>5 years) outcomes of patients with ULMCA disease underwent PCI with DES and coronary artery bypass grafting (CABG) and the predictors of adverse events.

Methods: All consecutive patients with ULMCA disease treated with DES implantation versus CABG in our center, between January 2003 and July 2009, were screened for analyzing.

Predictive Ability of the SYNergy Between Percutaneous Coronary Intervention with TAXus and Cardiac Surgery Score II for Long-term Mortality in Patients with Three-vessel Coronary Artery Disease Undergoing Percutaneous Coronary Intervention Treated with Second-generation Drug-eluting Stents.

Background: The SYNergy between percutaneous coronary intervention with TAXus and cardiac surgery Score II (SS-II) can well predict 4-year mortality in patients with complex coronary artery disease (CAD), and guide decision-making between coronary artery bypass graft surgery and percutaneous coronary intervention (PCI). However, there is lack of data regarding the utility of the SS-II in patients with three-vessel CAD undergoing PCI treated with second-generation drug-eluting stents (DES). The purpose of the present study was to evaluate the ability of the SS-II to predict long-term mortality in patients with three-vessel CAD undergoing PCI with second-generation DES.

[The value of SYNTAX score in predicting outcome patients undergoing percutaneous coronary intervention].

Objective: To assess the value of SYNTAX score to predict major adverse cardiac and cerebrovascular events (MACCE) among patients with three-vessel or left-main coronary artery disease undergoing percutaneous coronary intervention.

Methods: 190 patients with three-vessel or left-main coronary artery disease undergoing percutaneous coronary intervention (PCI) with Cypher select drug-eluting stent were enrolled. SYNTAX score and clinical SYNTAX score were retrospectively calculated.

[Impact of left ventricular systolic function on the outcomes of percutaneous coronary intervention for unprotected left main disease].

Objective: To evaluate the impact of left ventricular systolic function on the outcomes of percutaneous coronary intervention (PCI) for unprotected left main (ULM) disease.

Methods: The relevant baseline and outcome data of patients undergoing PCI for ULM disease at our hospital were collected from September 2006 to August 2009. The enrolled patients were divided into two groups according to left ventricular ejection fraction (LVEF): LVEF ≥ 40% group (n = 130) and LVEF < 40% group (n = 56).

Syntax score predicts clinical outcome in patients with three-vessel coronary artery disease undergoing percutaneous coronary intervention.

Background: The Syntax score was recently developed as a comprehensive, angiographic tool grading the complexity of coronary artery disease (CAD). It aims to assist in patient selection and risk stratification of patients with extensive CAD undergoing revascularization. However, the prognostic value of the Syntax score in patients undergoing percutaneous coronary intervention (PCI) has not been validated.
