Randomized Controlled Trial Multicenter StudyUse of ranolazine in patients with incomplete revascularization after percutaneous coronary intervention: design and rationale of the Ranolazine for Incomplete Vessel Revascularization Post-Percutaneous Coronary Intervention (RIVER-PCI) trial.
Incomplete revascularization (ICR) after percutaneous coronary intervention (PCI) is common and is associated with increased rates of rehospitalization, revascularization, and mortality. Adjunctive pharmacotherapy with ranolazine, an inhibitor of the late sodium current with anti-ischemic properties, may be effective in reducing recurrent events after PCI in patients with ICR.

Randomized Controlled Trial Multicenter Study Comparative StudyDesign and methods of European Ambulance Acute Coronary Syndrome Angiography Trial (EUROMAX): an international randomized open-label ambulance trial of bivalirudin versus standard-of-care anticoagulation in patients with acute ST-segment-elevation myocardial infarction transferred for primary percutaneous coronary intervention.
In patients with ST-segment elevation myocardial infarction (STEMI) triaged to primary percutaneous coronary intervention (PCI), anticoagulation often is initiated in the ambulance during transfer to a PCI site. In this prehospital setting, bivalirudin has not been compared with standard-of-care anticoagulation. In addition, it has not been tested in conjunction with the newer P2Y12 inhibitors prasugrel or ticagrelor. ⋯ The EUROMAX trial will test whether bivalirudin started in the ambulance and continued for 4 hours after primary PCI improves clinical outcomes compared with guideline-recommended standard-of-care heparin-based regimens, and will also provide information on the combination of bivalirudin with prasugrel or ticagrelor.

Randomized Controlled Trial Comparative StudyEverolimus-eluting stents in patients undergoing percutaneous coronary intervention: final 3-year results of the Clinical Evaluation of the XIENCE V Everolimus Eluting Coronary Stent System in the Treatment of Subjects With de Novo Native Coronary Artery Lesions trial.
We compared the outcomes of patients treated with everolimus-eluting stents (EES) versus paclitaxel-eluting stents (PES) at 3 years from the large-scale randomized SPIRIT IV trial. ⋯ When compared with PES, EES provides durable and significant reduction in TLF, especially due to its enhanced safety profile, with lower rates of death or MI and stent thrombosis up to 3 years.

Multicenter Study Comparative Study Observational StudyRadial versus femoral approach comparison in percutaneous coronary intervention with intraaortic balloon pump support: the RADIAL PUMP UP registry.
The role of intraaortic balloon pump (IABP) during percutaneous coronary intervention (PCI) in high-risk acute patients remains debated. Device-related complications and the more complex patient management could explain such lack of clinical benefit. We aimed to assess the impact of transradial versus transfemoral access for PCI requiring IABP support on vascular complications and clinical outcome. ⋯ In this observational registry, high-risk patients undergoing PCI and requiring IABP support appeared to have fewer NACEs if transradial access was used instead of transfemoral, mainly due to fewer access-related bleedings. Given the inherent limitations of this retrospective work, including the inability to adjust for unknown confounders, further controlled studies are warranted to confirm or refute these findings.

The association between smoking and long-term outcomes after non-ST-segment elevation myocardial infarction in older patients.
Prior studies have observed that smokers have paradoxically favorable 1-year mortality rates after acute coronary syndromes, but it is unknown whether this association extends to long-term outcomes and to older patients. ⋯ Among older non-ST-segment elevation myocardial infarction patients, we found that smokers had significantly higher long-term risks for both mortality and recurrent myocardial infarction. These results support ongoing efforts to promote smoking cessation, even among older patients.
