Per-Vessel Level Analysis of Fractional Flow Reserve and Instantaneous Wave-Free Ratio Discordance - Insights From the AJIP Registry.

Background: The per-vessel level impact of physiological pattern of disease on the discordance between fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR) has not been clarified.

Methods and results: Using the AJIP registry, vessels with FFR/iFR discordance (133/671 [19.8%]) were analyzed.

Early responsiveness to continuous erythropoietin receptor activator predicts renal prognosis and is determined by a novel antioxidative marker in non-dialysis chronic kidney disease: a prospective, observational, single-center study.

Background: Responsiveness to erythropoietin-stimulating agents (ESAs) is important for anemia management in chronic kidney disease (CKD). We assessed the effects of a continuous erythropoietin receptor activator (CERA) on renoprotection beyond anemia management and the correlation between the responsiveness to ESAs and oxidative stress markers in CKD.

Methods: This single-center, prospective, observational study was conducted over 24 months.

Algorithmic Versus Expert Human Interpretation of Instantaneous Wave-Free Ratio Coronary Pressure-Wire Pull Back Data.

Objectives: The aim of this study was to investigate whether algorithmic interpretation (AI) of instantaneous wave-free ratio (iFR) pressure-wire pull back data would be noninferior to expert human interpretation.

Background: Interpretation of iFR pressure-wire pull back data can be complex and is subjective.

Methods: Fifteen human experts interpreted 1,008 iFR pull back traces (691 unique, 317 duplicate).

Physiological Pattern of Disease Assessed by Pressure-Wire Pullback Has an Influence on Fractional Flow Reserve/Instantaneous Wave-Free Ratio Discordance.

Background: Fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR) disagree on the hemodynamic significance of a coronary lesion in ≈20% of cases. It is unknown whether the physiological pattern of disease is an influencing factor for this. This study assessed whether the physiological pattern of coronary artery disease influences discordance between FFR and iFR measurement.

Correction to: Eribulin, trastuzumab, and pertuzumab as first-line therapy for patients with HER2-positive metastatic breast cancer: a phase II, multicenter, collaborative, open-label, single-arm clinical trial.

The authors would like to note the replacement of Fig. 2b, for which Fig. 2a was placed erringly, with appropriate Fig.

Eribulin, trastuzumab, and pertuzumab as first-line therapy for patients with HER2-positive metastatic breast cancer: a phase II, multicenter, collaborative, open-label, single-arm clinical trial.

Purpose To examine the efficacy and safety of triple therapy with eribulin, trastuzumab, and pertuzumab in patients with HER2-positive metastatic breast cancer (MBC) who never received any prior therapy in the first-line metastatic/advanced setting. Methods Eribulin 1.4 mg/m (days 1 and 8), trastuzumab 8 mg/kg over 90 min and 6 mg/kg over 30 min, and pertuzumab 840 mg/body over 60 min and 420 mg/body over 30 min were administered intravenously in 21-day cycles.

Conduction Delay-Induced J-Wave Augmentation in Patients With Coronary Heart Disease.

Electrocardiogram records were surveyed for the presence of an atrial premature beat (APB) and J waves in patients with coronary heart disease and patients with noncardiac diseases. The prevalence and response of J waves to sudden shortening of the RR interval on the conducted APB were determined and compared between the 2 patients groups. The change in the QRS complexes on the APB was also determined.

Pre-Angioplasty Instantaneous Wave-Free Ratio Pullback Predicts Hemodynamic Outcome In Humans With Coronary Artery Disease: Primary Results of the International Multicenter iFR GRADIENT Registry.

Objectives: The authors sought to evaluate the accuracy of instantaneous wave-Free Ratio (iFR) pullback measurements to predict post-percutaneous coronary intervention (PCI) physiological outcomes, and to quantify how often iFR pullback alters PCI strategy in real-world clinical settings.

Background: In tandem and diffuse disease, offline analysis of continuous iFR pullback measurement has previously been demonstrated to accurately predict the physiological outcome of revascularization. However, the accuracy of the online analysis approach (iFR pullback) remains untested.

Coronary arterial spasm detected by coronary computed tomography angiography and confirmed by intravascular ultrasound.

A 40-year-old man was admitted to our hospital for chest pain after smoking. Coronary computed tomography angiography showed severe stenosis in the left anterior descending artery. The stenosis site had no plaque on stretched curved multiplanar reconstruction and short-axis images.

Effects of caffeine on fractional flow reserve values measured using intravenous adenosine triphosphate.

We investigated the effects of caffeine intake on fractional flow reserve (FFR) values measured using intravenous adenosine triphosphate (ATP) before cardiac catheterization. Caffeine is a competitive antagonist for adenosine receptors; however, it is unclear whether this antagonism affects FFR values. Patients were evenly randomized into 2 groups preceding the FFR study.

Phase II clinical study of eribulin monotherapy in Japanese patients with metastatic breast cancer who had well-defined taxane resistance.

No clinical evidence on the efficacy and safety of eribulin monotherapy has been obtained by a prospective clinical study in patients with metastatic breast cancer (MBC) who had well-defined taxane resistance. The present Phase II, multicenter, single-arm, open-label study aimed to obtain the evidence. Japanese female patients, aged 33-74 years who had the metastasis of taxane-resistant and histopathologically confirmed breast cancer, received eribulin mesylate 1.

The impact of C4d-negative acute antibody-mediated rejection on short-term prognosis among kidney transplant recipients.

Aim: We aimed to investigate the clinical and pathological features of C4d-negative acute antibody-mediated rejection (aAMR), and examined the impact of C4d-negative aAMR on short-term prognosis.

Methods: From 2005 to 2011, 626 kidney transplantations were performed in our institution and related hospitals. We excluded 174 ABO-incompatible transplantations, and analysed clinical and pathological data from the remaining 452 until December 2013.

Papaverine-induced polymorphic ventricular tachycardia during coronary flow reserve study of patients with moderate coronary artery disease.

Background: Papaverine is useful for evaluating the functional status of a coronary artery, but it may provoke malignant ventricular arrhythmia (VA). The aim of this study was to investigate the incidence, and clinical and ECG characteristics of patients with papaverine-induced VAs. METHODS AND RESULTS: The 182 consecutive patients underwent fractional flow reserve (FFR) measurement of 277 lesions.

Clinical outcomes of recipients with aplastic bone disease after renal transplantation.

Objectives: We expect that if chronic renal failure (CRF) is improved after renal transplantation (RTx), dialysis osteopathy bone lesions would also recover to normal. Nevertheless, it is controversial whether bone lesions really improve after RTx. In this study, we evaluated whether pathological dialysis osteopathy improved after RTx.

Successful escape of acute ischemic stroke patients from hospital to home: clinical note.

I describe four patients who successfully escaped from the hospital to their own home during the acute phase of ischemic stroke. This is a very rare phenomenon (seen in 0.35% of 1150 consecutive patients with first ischemic stroke within 24 h after onset), but the patients had rather uniform clinical characteristics.

Diffusion-weighted ASPECTS as an independent marker for predicting functional outcome.

Whether lesion volume on diffusion-weighted MRI imaging (DWI) can reliably predict functional outcome in acute ischemic stroke is controversial. The aim of our study was to assess whether the Alberta Stroke Program Early CT Score (ASPECTS) on DWI is useful for predicting functional outcome in patients with anterior circulation infarction with a broad range of severities. Three-hundred and fifty patients with first-ever ischemic stroke in the anterior circulation within 24 h of onset were enrolled.

Posterior circulation ASPECTS on diffusion-weighted MRI can be a powerful marker for predicting functional outcome.

There are few studies regarding functional outcome and lesion extent on diffusion-weighted MRI (DWI) in patients with posterior circulation (PC) infarction. The aim of our study was to assess whether a newly proposed posterior circulation Alberta Stroke Program Early CT Score (pc-ASPECTS) on DWI is useful for predicting functional outcome in PC patients. One hundred thirty-two patients with first-ever ischemic stroke in the posterior circulation within 24 h of onset who were admitted to our hospital were enrolled in the study.

Clinical-diffusion mismatch defined by NIHSS and ASPECTS in non-lacunar anterior circulation infarction.

Objectives: Instead of the mismatch in MRI between the perfusion-weighted imaging (PWI) lesion and the smaller diffusion-weighted imaging (DWI) lesion (PWI-DWI mismatch), clinical-DWI mismatch (CDM) has been proposed as a new diagnostic marker of brain tissue at risk of infarction in acute ischemic stroke. The Alberta Stroke Program Early CT Score (ASPECTS) has recently been applied to detect early ischemic change of acute ischemic stroke. The present study applies the CDM concept to DWI data and investigated the utility of the CDM defined by the NIH Stroke Scale (NIHSS) and ASPECTS in patients with non-lacunar anterior circulation infarction.

[Endovascular stent-graft repair for thoracic aortic aneurysm].

Endovascular stent-grafting holds great potential as a minimally invasive alternative to open surgery for thoracic aortic aneurysm. Although there have been several commercially available stent graft systems applied to abdominal aortic aneurysm in the United States, Gore TAG is the only device that is approved by Food and Drug Association (FDA) for thoracic aortic aneurysm repair. Experience of endovascular aneurysm repair by our homemade system and TAG device which is crafted particularly for the thoracic aorta is reported.

Predictors of good prognosis in total anterior circulation infarction within 6 h after onset under conventional therapy.

Objective: We investigated the predictors of good prognosis in total anterior circulation infarction (TACI), under conventional therapy.

Methods: We enrolled 166 patients with first-ever ischemic stroke within 6 h after onset with symptoms of TACI. Sixty-three patients (38.

[Predictors of good prognosis in total anterior circulation infarction].

We analysed the predictive factors for relatively good prognosis in the patients with total anterior circulation infarction (TACI) defined by the Oxfordshire Community Stroke Project. One hundred patients with first-ever ischemic stroke within 6 hours of onset were enrolled. Outcomes were assessed at 3 months using the modified Rankin Scale (mRS), and rated as good if the mRS was 0 to 3, and as bad if the mRS was 4 or 5, or the patient was dead.
