Clinical Trial | By Yannopoulos D, Bartos JA, Raveendran G et al.
BACKGROUND - The prevalence of coronary artery disease (CAD) among patients with refractory out-of-hospital(OH) ventricular fibrillation (VF)/ventricular tachycardia (VT) cardiac arrest is unknown. OBJECTIVES - The goal of this study was to describe the prevalence and complexity of CAD and report survival to hospital discharg...
Clinical Trial | By Xu B, Tu S, Hu S et al.
BACKGROUND - Quantitative flow ratio (QFR) is a novel angiography-based method for deriving fractional flow reserve (FFR) without pressure wire or induction of hyperemia. The accuracy of QFR when assessed online in the catheterization laboratory has not been adequately examined to date. OBJECTIVES - The goal of this study was to assess the diagn...
Review Article | By Jang JS, Song YJ, Kang W et al.
OBJECTIVES - The aim of this study was to systematically review and perform a meta-analysis of randomized trials and observational studies of intravascular ultrasound (IVUS)-guided versus angiography-guided implantation of drug-eluting stents (DES). BACKGROUND - Although studies in the bare-metal stents era suggested that there were clinical benefits to IVUS guidance, it is s...
Silent Myocardial Infarction and Long-Term Risk of Heart Failure: The ARIC Study
Original Research | By Qureshi WT, Zhang ZM, Soliman EZ et al.
BACKGROUND - Although silent myocardial infarction (SMI) accounts for about one-half of the total number of myocardial infarctions (MIs), the risk of heart failure (HF) among patients with SMI is not well established. OBJECTIVES - The purpose of this study was to examine the association of SMI and clinically manifested myocardial infarction (CMI) with HF, as compared with patients...
Clinical Trial | By Motovska Z, Hlinomaz O, PRAGUE-18 Study Group et al.
BACKGROUND - Early outcomes of patients in the PRAGUE-18 (Comparison of Prasugrel and Ticagrelor in the Treatment of Acute Myocardial Infarction) study did not find any significant differences between 2 potent P2Y12 inhibitors. OBJECTIVES - The 1-year follow-up of the PRAGUE-18 study focused on: 1) a comparison of efficacy and safety between prasugrel and ticagrelor; ...
Effect of Plaque Burden and Morphology on Myocardial Blood Flow and Fractional Flow Reserve
Clinical Trial | By Driessen RS, Stuijfzand WJ, Knaapen P et al.
BACKGROUND - Atherosclerotic plaque characteristics may affect downstream myocardial perfusion, as well as coronary lesion severity. OBJECTIVES - This study sought to evaluate the association between quantitative plaque burden and plaque morphology obtained using coronary computed tomography angiography (CTA) and quantitative myocardial perfusion obtained using [15O]H2O positron emission tomography (PET),...
Clinical Case Study | By Ohya M, Morimoto T, Kubo S et al.
BACKGROUND - Data on outcomes of non-left main coronary bifurcation lesions treated with the 2-stent strategy using 2nd-generation drug-eluting stents (DES) are insufficient. Methods and Results: The 2-year outcomes and predictors of target lesion revascularization (TLR) in 356 patients with 364 non-left main coronary bifurcation lesions treated with the 2-stent strategy using 2nd-generation DES were retrospectively eva...
Step-by-step manual for planning and performing bifurcation PCI: a resource-tailored approach
Review Article | By Milasinovic D, Wijns W, Ntsekhe M et al.
As bifurcation PCI can often be resource-demanding due to the use of multiple guidewires, balloons and stents, different technical options are sometimes being explored, in different local settings, to meet the need of optimally treating a patient with a bifurcation lesion, while being confronted with limited material resources. Therefore, it seems important to keep a proper balance between what is recognised as the contemporary state of the art,...
Use of the Instantaneous Wave-free Ratio or Fractional Flow Reserve in PCI
Original Research | By Davies JE, Sen S, Dehbi HM et al.
BACKGROUND - Coronary revascularization guided by fractional flow reserve (FFR) is associated with better patient outcomes after the procedure than revascularization guided by angiography alone. It is unknown whether the instantaneous wave-free ratio (iFR), an alternative measure that does not require the administration of adenosine, will offer benefits similar to those of FFR. METHODS - We randomly assig...
