Review Meta AnalysisRadial versus femoral access for primary percutaneous interventions in ST-segment elevation myocardial infarction patients: a meta-analysis of randomized controlled trials.
This study sought to determine the safety and efficacy of radial access compared with femoral access for primary percutaneous coronary intervention (PCI) in patients with ST-segment elevation myocardial infarction (STEMI). ⋯ In STEMI patients undergoing primary PCI, the radial approach is associated with favorable outcomes and should be the preferred approach for experienced radial operators.

Review Meta AnalysisA systematic review and meta-analysis on primary percutaneous coronary intervention of an unprotected left main coronary artery culprit lesion in the setting of acute myocardial infarction.
This study sought to evaluate 30-day all-cause mortality of patients treated with primary percutaneous coronary intervention (PCI) presenting with an acute myocardial infarction (AMI) due to an unprotected left main coronary artery (ULMCA) culprit lesion. In addition, an average estimated mortality rate was extrapolated from the available data. ⋯ In this large meta-analysis of patients treated with primary PCI for AMI due to an ULMCA culprit lesion, the 30-day all-cause mortality in patients presenting with shock is much higher than in patients not presenting with shock. The estimated all-cause mortality data may serve as a benchmark for future reference.

Review Meta AnalysisOpen versus endovascular stent graft repair of abdominal aortic aneurysms: a meta-analysis of randomized trials.
This study sought to evaluate the short-, intermediate-, and longer-term outcomes after endovascular versus open repair of abdominal aortic aneurysms (AAA), including both AAA-related and all-cause mortality. ⋯ In patients randomized to open or endovascular AAA repair, all-cause perioperative mortality, as well as AAA-related mortality at short- and intermediate-term follow-up are lower in patients undergoing endovascular stent graft placement. This was associated with greater reintervention in the endovascular group noted at intermediate follow-up. Long-term survival appears to converge between the 2 groups.

Meta AnalysisImpact of lesion length and vessel size on clinical outcomes after percutaneous coronary intervention with everolimus- versus paclitaxel-eluting stents pooled analysis from the SPIRIT (Clinical Evaluation of the XIENCE V Everolimus Eluting Coronary Stent System) and COMPARE (Second-generation everolimus-eluting and paclitaxel-eluting stents in real-life practice) Randomized Trials.
The aim of this study was to investigate the impact of reference vessel diameter (RVD) and lesion length (LL) on the relative safety and efficacy of everolimus-eluting stents (EES) and paclitaxel-eluting stents (PES). ⋯ Patients with short lesions in large vessels have low rates of MACE at 2 years after treatment with either EES or PES. In higher-risk patients with long lesions and/or small vessels, EES results in significant improvements in both clinical safety and efficacy outcomes. (A Clinical Evaluation of the XIENCE V Everolimus Eluting Coronary Stent System in the Treatment of Patients With de Novo Native Coronary Artery Lesions; NCT00180310; SPIRIT III: A Clinical Evaluation of the Investigational Device XIENCE V Everolimus Eluting Coronary Stent System [EECSS] in the Treatment of Subjects With de Novo Native Coronary Artery Lesions; NCT00180479; SPIRIT IV Clinical Trial: Clinical Evaluation of the XIENCE V Everolimus Eluting Coronary Stent System in the Treatment of Subjects With de Novo Native Coronary Artery Lesions; NCT00307047; A Randomized Controlled Trial of Everolimus-eluting Stents and Paclitaxel-eluting Stents for Coronary Revascularization in Daily Practice: The COMPARE Trial; NCT01016041).

Meta AnalysisPersistent coronary no flow after wire insertion is an early and readily available mortality risk factor despite successful mechanical intervention in acute myocardial infarction: a pooled analysis from the STRATEGY (Single High-Dose Bolus Tirofiban and Sirolimus-Eluting Stent Versus Abciximab and Bare-Metal Stent in Acute Myocardial Infarction) and MULTISTRATEGY (Multicenter Evaluation of Single High-Dose Bolus Tirofiban Versus Abciximab With Sirolimus-Eluting Stent or Bare-Metal Stent in Acute Myocardial Infarction Study) trials.
These studies sought to investigate the impact on mortality of coronary flow after passage of the wire through the culprit vessel in patients with ST-segment elevation myocardial infarction (STEMI) undergoing mechanical reperfusion. ⋯ STEMI patients displaying persistent no-flow AWI have a lower survival rate despite an apparently successful mechanical intervention. As an early marker for high residual mortality risk, persistent no-flow AWI may qualify STEMI patients for dedicated pharmacomechanical treatment strategies.
