Switching from Clopidogrel to Prasugrel in patients undergoing PCI: A meta-analytic overview
Very short dual antiplatelet therapy after PCI and new DES: a meta-analysis of 5 randomized trials
Very early (1-3 months) discontinuation of dual antiplatelet therapy (DAPT) has been recently proposed in percutaneous coronary interventions with modern drug-eluting stents (DES), with contrasting results. The aim of the present meta-analysis was to evaluate the prognostic impact of very short DAPT regimens vs the standard 12-month regimen in patients undergoing percutaneous coronary intervention with new DES
Stenting and abciximab in primary angioplasty: a review of current status
Improvement of stent deployment techniques and advances in antiplatelet therapy have shown that stenting in the setting of ST-elevation myocardial infarction (STEMI) is safe and effective. Randomized trials have found that as compared to balloon angioplasty, coronary stenting does not reduce mortality and reinfarction, despite the reduction in target vessel revascularization. Furthermore, these benefits seem to be reduced when applied to unselected patients with STEMI. Direct stenting represents an attractive strategy with potential benefits in terms of myocardial perfusion. Future randomized trials are needed to evaluate if this strategy is associated with a significant impact on outcome, and to provide cost-benefit analysis of an unrestricted use of drug-eluting stent in this high-risk subset of patients. Data from randomized trials have shown that the additional use of abciximab reduces mortality in primary angioplasty. Since the feasibility of long-distance transportation has been shown in several randomized trials, early pharmacological pretreatment may confer further advantages by early recanalization and shorter ischemic time, particularly in high-risk patients. Further large randomized trials are needed to clarify the potential role of small molecules in primary angioplasty for STEMI
Acetylsalicylic acid desensitization in patients with coronary artery disease: A comprehensive overview of currently available protocols
Contrast volume to creatinine clearance ratio for the prediction of contrast-induced nephropathy in patients undergoing coronary angiography or percutaneous intervention
Contrast-induced nephropathy is a common complication of procedures that are likely to use contrast media. The identification of high-risk patients and preventive optimal hydration are key measures to reduce the incidence of contrast-induced nephropathy. The aim of this study was to evaluate the role of the contrast volume to creatinine clearance ratio (V/CrCl) in the prediction of contrast-induced nephropathy after coronary angiography or percutaneous coronary intervention

Polymer-Free vs. Polymer-Coated Drug-Eluting Stents for the Treatment of Coronary Artery Disease: A Meta-Analysis of 16 Randomized Trials
Background: Polymer-coating represents one of components of drug-eluting stents (DES) to have experienced a more intensive technological evolution. Polymer-free DES (PF-DES) have offered promising angiographic results, with earlier complete re-endothelization, potentially reducing the thrombotic risk and offering the option of a shorter antiplatelet therapy. However, contrasting prognostic data have been reported so far with PF-DES. Therefore, the aim of the present study was to perform a comprehensive updated meta-analysis of randomized trials (RCT) comparing the impact of PF-DES vs polymer- coated DES (PC-DES) on clinical outcome.Methods: Literature and main scientific session abstracts were searched for RCTs comparing PF-DES vs PC-DES for the treatment of CAD. The primary efficacy endpoint was mortality, secondary endpoints were cardiovascular death, myocardial infarction, target lesion revascularization (TLR) and stent thrombosis.Results: We included 16 randomized clinical trials, with a total of 15,689 patients, including 50.6% randomized to PF-DES. At a median follow-up of 24 months, PF-DES were associated to a significant reduction in mortality as compared to PC-DES (0.82 [0.68, 0.99], p=.03, I2 = 0%; phet = 0.93). However, no significant benefit was observed in terms of cardiovascular death or major ischemic endpoints (respectively CV death: OR [95% CI]= 0.92 [0.71, 1.18] p=.50, I2= 0.50; phet= 0.84; MI: OR [95% CI]= 1.08 [0.90, 1.29], p=.42; I2= 0%, phet= 0.98; TLR: OR [95% CI]= 1.02 [0.78, 1.32], p=.91; I2= 0.63 phet = 0.0003; ST: OR [95% CI]= 0.98 [0.87, 1.10], p=.72; I2= 0% phet= 0.64). By meta-regression analysis, the mortality benefits of PF-DES were not conditioned by the rate of diabetes mellitus or acute coronary syndromes.Conclusions: Based on the current meta-analysis, PF-DES are associated to a significant reduction in mortality as compared to PC-DES, but not in the occurrence of major ischemic events. Future larger studies are certainly needed to further investigate and confirm our findings, especially in particular subsets of patients, such as those with high bleeding risk or acute myocardial infarction.
