Percutaneous coronary intervention with everolimus-eluting bioresorbable vascular scaffolds in routine clinical practice: early and midterm outcomes …

2015

Clinical data on the early and midterm outcomes of bioresorbable vascular scaffolds (BVS) in routine clinical practice are limited. To fill this gap, we report on the early and midterm clinical outcomes of PCI with everolimus-eluting BVS from the large multicentre GHOST-EU registry.Between November 2011 and January 2014, 1,189 patients underwent percutaneous coronary intervention with one or more BVS (Absorb BVS; Abbott Vascular, Santa Clara, CA, USA) at 10 European centres. The primary outcome of interest was target lesion failure (TLF), defined as the combination of cardiac death, target vessel myocardial infarction, or clinically driven target lesion revascularisation (TLR). A total of 1…

Relationship between Psychophysical Measures of Retinal Ganglion Cell Density and In Vivo Measures of Cone Density in Glaucoma.

2017

Purpose Considerable between-individual variation in retinal ganglion cell (RGC) density exists in healthy individuals, making identification of change from normal to glaucoma difficult. In ascertaining local cone-to-RGC density ratios in healthy individuals, we wished to investigate the usefulness of objective cone density estimates as a surrogate of baseline RGC density in glaucoma patients, and thus a more efficient way of identifying early changes. Design Exploratory cohort study. Participants Twenty glaucoma patients (60% women) with a median age of 54 years and mean deviation (MD) in the visual field of –5 dB and 20 healthy controls (70% women) with a median age of 57 years and a mean…

Prognostic Implications of Tissue Doppler Imaging-Derived E/Ea Ratio in Acute Heart Failure Patients

2014

Background Tissue Doppler–derived transmitral to mitral annular early diastolic velocity ratio (E/Ea), as a noninvasive estimation of left ventricular (LV) filling pressures, is a strong prognosticator in various cardiac scenarios including chronic heart failure; nevertheless, its utility for risk stratification in the whole spectrum of acute heart failure (AHF) patients remains elusive. Thus, the aim of this study was to determine the association between E/Ea ratio and 1-year mortality in nonselected patients with AHF. Methods The study included 417 consecutive patients admitted for AHF. Twenty-two patients were excluded due to nonaccurate Ea measurements, leaving the final sample to be 39…

Usefulness of Right Ventricular to Pulmonary Circulation Coupling as an Indicator of Risk for Recurrent Admissions in Heart Failure With Preserved Ej…

2019

In recent years, the study of right ventricular (RV) to pulmonary circulation (PC) coupling in heart failure with preserved ejection fraction (HFpEF) has been a matter of special interest. Tricuspid annular plane systolic excursion (TAPSE) to pulmonary artery systolic pressure (PASP) ratio has emerged as a reliable noninvasive index of RV to PC coupling. Thus, we hypothesized that TAPSE/PASP would be a predictor of readmission burden in HFpEF. One thousand one hundred and twenty seven consecutive HFpEF patients discharged for acute HF were included. In 367 patients (32.6%), PASP could not be accurately measured by echocardiography, leaving the final sample size to be 760 patients. Negative …

Long-term follow-up study of endarterectomy versus angioplasty in patients with symptomatic severe carotid stenosis trial

2014

Background and Purpose— We aimed at comparing the long-term benefit–risk balance of carotid stenting versus endarterectomy for symptomatic carotid stenosis. Methods— Long-term follow-up study of patients included in Endarterectomy Versus Angioplasty in Patients With Symptomatic Severe Carotid Stenosis (EVA-3S), a randomized, controlled trial of carotid stenting versus endarterectomy in 527 patients with recently symptomatic severe carotid stenosis, conducted in 30 centers in France. The main end point was a composite of any ipsilateral stroke after randomization or any procedural stroke or death. Results— During a median follow-up of 7.1 years (interquartile range, 5.1–8.8 years; maximum 1…

Clinical course of patients with symptomatic isolated superficial vein thrombosis: the ICARO follow‐up study

2017

Essentials Late sequelae of isolated superficial vein thrombosis (iSVT) have rarely been investigated. We studied 411 consecutive outpatients with acute iSVT with a median follow-up of three years. Male sex and cancer are risk factors for future deep vein thrombosis or pulmonary embolism. Patients without cancer appear to be at a negligible risk for death. SUMMARY Background Studies of long-term thromboembolic complications and death following acute isolated superficial vein thrombosis (iSVT) of the lower extremities are scarce. Objectives To investigate the course of iSVT in the setting of an observational multicenter study. Methods We collected longitudinal data of 411 consecutive outpati…

Sex-specific differences in chronic thromboembolic pulmonary hypertension. Results from the European CTEPH registry

2019

BACKGROUND: Women are more susceptible than men to several forms of pulmonary hypertension, but have better survival. Sparse data are available on chronic thromboembolic pulmonary hypertension (CTEPH). METHODS: We investigated sex-specific differences in the clinical presentation of CTEPH, performance of pulmonary endarterectomy (PEA), and survival. RESULTS: Women constituted one-half of the study population of the European CTEPH registry (N = 679) and were characterized by a lower prevalence of some cardiovascular risk factors, including prior acute coronary syndrome, smoking habit, and chronic obstructive pulmonary disease, but more prevalent obesity, cancer, and thyroid diseases. The med…

International Normalized Ratio and Mortality Risk in Acute Heart Failure and Nonvalvular Atrial Fibrillation Patients Receiving Vitamin K Antagonists

2019

Introduction and objectives: Heart failure patients with nonvalvular atrial fibrillation (NVAF) on treatment with vitamin K antagonists (VKA) often have suboptimal international normalized ratio (INR) values. Our aim was to evaluate the association between INR values at admission due to acute heart failure and mortality risk during follow-up. Methods: In this observational study, we retrospectively assessed INR on admission in 1137 consecutive patients with acute heart failure and NVAF who were receiving VKA treatment. INR was categorized into optimal values (INR = 2-3, n = 210), subtherapeutic (INR 3, n = 267). Because INR did not meet the proportional hazards assumption for mortality, res…

Antitumor Necrosis Factor Agents to Treat Endoscopic Postoperative Recurrence of Crohn's Disease: A Nationwide Study With Propensity-Matched Score An…

2020

INTRODUCTION: Patients with Crohn's disease experiencing endoscopic postoperative recurrence (POR) may benefit from antitumor necrosis factor (TNF) agents but scarce data on this are available. Our aim was to assess the efficacy of anti-TNF in improving mucosal lesions in patients with endoscopic POR. METHODS: Multicenter, retrospective, study of patients with Crohn's disease who underwent therapy with anti-TNF agents for endoscopic POR (Rutgeerts score > i1). Treatment outcomes were assessed by the findings in the last ileocolonoscopy performed after anti-TNF therapy was initiated. Endoscopic improvement and remission were defined as any reduction in the baseline Rutgeerts score and by a R…
