CIRCULATION: CARDIOVASCULAR INTERVENTIONS. Coronary Interventions. Remote Ischemic Preconditioning Improves Outcome at 6 Years After Elective Percutaneous Coronary Intervention. The CRISP Stent Trial Long-term Follow-up

William R. Davies, PhD, MRCP, Adam J. Brown, MRCP, William Watson, MRCP, Liam M. McCormick, MRCP, Nick E.J. West, MD, FRCP, David P. Dutka, MD, FRCP and Stephen P. Hoole, MA, DM, MRCP

Background: Postprocedural myocardial infarction (type 4a) has been shown to be an adverse prognostic indicator after elective percutaneous coronary intervention (PCI). The Cardiac Remote Ischemic Preconditioning in Coronary Stenting (CRISP Stent) study demonstrated that remote ischemic preconditioning reduced procedural symptoms, ECG ST-segment deviation, and cardiac troponin I release after elective PCI and reduced the major adverse cardiac and cerebral event (MACCE) rate at 6 months. We were interested to confirm if this early benefit in MACCE rate in the remote ischemic preconditioning group was sustained long-term.

CIRCULATION: CARDIOVASCULAR INTERVENTIONS. Coronary Artery Disease. Long-term Morphofunctional Remodeling of Internal Thoracic Artery Grafts. A Frequency-Domain Optical Coherence Tomography Study

Italo Porto, MD, Mario Gaudino, MD, Giovanni Luigi De Maria, MD, Luca Di Vito, MD, Rocco Vergallo, MD, Piergiorgio Bruno, MD, Giorgia Bonalumi, MD, Francesco Prati, MD, Leonardo Bolognese, MD, Filippo Crea, MD and Massimo Massetti, MD

Background: Internal thoracic arteries (ITAs) are frequently anastomosed to the coronary circulation for bypass grafting. The purpose of this research was to investigate in vivo the long-term morphofunctional changes of ITAs after their use as coronary artery bypass conduits, by comparing the morphological features and vasoreactivity of the grafted left ITA (LITA) with the native, nonharvested right ITA (RITA) in the same patient.

CIRCULATION: CARDIOVASCULAR INTERVENTIONS. Pharmacology. Differential Effect of Ticagrelor Versus Prasugrel on Coronary Blood Flow Velocity in Patients With Non–ST-Elevation Acute Coronary Syndrome Undergoing Percutaneous Coronary Intervention. An Exploratory Study

Dimitrios Alexopoulos, MD, PhD, FESC, Athanasios Moulias, MD, Nikolaos Koutsogiannis, MD, Ioanna Xanthopoulou, MD, Apostolos Kakkavas, MD, Eleni Mavronasiou, MD, Periklis Davlouros, MD and George Hahalis, MD, PhD

Background: Prasugrel and ticagrelor provide a superior anti-ischemic action than clopidogrel, with some of ticagrelor’s benefits possibly attributed to adenosine-mediated mechanisms. We aimed to compare the effect of maintenance dose of ticagrelor versus prasugrel on coronary blood flow velocity (CBFV) during increasing doses of intravenously administered adenosine.

CIRCULATION: CARDIOVASCULAR INTERVENTIONS. Myocardial Infarction. Prognosis of Patients With Non–ST-Segment–Elevation Myocardial Infarction and Nonobstructive Coronary Artery Disease. Propensity-Matched Analysis From the Acute Catheterization and Urgent Intervention Triage Strategy Trial

David Planer, MD, MSc, Roxana Mehran, MD, E. Magnus Ohman, MD, Harvey D. White, DSc, Jonathan D. Newman, MD, MPH, Ke Xu, PhD and Gregg W. Stone, MD

Background: Troponin elevation is a risk factor for mortality in patients with non–ST-segment–elevation acute coronary syndromes. However, the prognosis of patients with troponin elevation and nonobstructive coronary artery disease (CAD) is unknown. Our objective was therefore to evaluate the impact of nonobstructive CAD in patients with non–ST-segment–elevation acute coronary syndromes and troponin elevation enrolled in the Acute Catheterization and Urgent Intervention Triage Strategy (ACUITY) trial.

CIRCULATION: CARDIOVASCULAR INTERVENTIONS. Coronary Interventions. Transulnar Compared With Transradial Artery Approach as a Default Strategy for Coronary Procedures. A Randomized Trial The Transulnar or Transradial Instead of Coronary Transfemoral Angiographies Study (The AURA of ARTEMIS Study)

George Hahalis, MD, PhD, Grigorios Tsigkas, MD, Ioanna Xanthopoulou, MD, Spyridon Deftereos, MD, Antonios Ziakas, MD, PhD, Konstantinos Raisakis, MD, Christos Pappas, MD, Aggelos Sourgounis, MD, Nikos Grapsas, MD, Periklis Davlouros, MD, PhD, Anastasia Galati, MD, Theodora-Eleni Plakomyti, MD, Panagiota Mylona, MD, Ioannis Styliadis, MD, PhD, Vlassis Pyrgakis, MD, FESC and Dimitrios Alexopoulos, MD, PhD, FESC

Background: The ulnar artery is rarely selected for coronary angiography or percutaneous coronary intervention despite the expanding use of the transradial approach. We aimed to establish noninferiority of a default transulnar relative to transradial approach in terms of feasibility and safety.
