AbstractPurpose of ReviewBiomarkers of cardiac fibrosis closely track the disease state that gives rise to heart failure. The purpose of this review is to highlight recent data on the use of soluble ST2, galectin-3, and procollagen, three markers of cardiac fibrosis, for aiding with prognostication, and to explore the use of these biomarkers for guiding therapy.Recent FindingsSoluble ST2, galectin-3, and procollagen are prognostic in both acute and chronic heart failure, and data are emerging as to their potential uses for guiding therapies. Mortality benefit from exercise, cardiac resynchronization therapy, statin use, as...

Abstract Background: Approximately 20-40% of recipients of cardiac resynchronization therapy (CRT) do not respond to it based on the current patient selection criteria. The purpose of this study was to identify baseline parameters that can predict CRT response and to evaluate the effect of those predictive parameters on long-term prognosis. Methods: This was a retrospective, nonrandomized, noncontrolled cohort study. Patients who received CRT in our centre were divided into responders and nonresponders by the definition of CRT response (an increase in left ventricular ejection fraction (LVEF) of ≥5% and im...

ConclusionThe results of this sub ‐analysis demonstrate that the CRT‐DX system can provide similar CRT responses and significantly fewer complications when compared to a similar cohort with a conventional three‐lead CRT‐D system.This article is protected by copyright. All rights reserved.

CONCLUSION: Surface ECG allows the diagnosis of atrioventricular and intraventricular conduction disorder and its anatomical block site most of the time, without the need for invasive tests such as electrophysiological study. Dysfunctions of cardiac implantable electronic devices can be diagnosed by ECG, as well as the prediction of response to cardiac resynchronization therapy.

This study aims to explore the predictive values of both systolic LVMD and diastolic LVMD for CRT in DCM patients.MethodsEighty-four consecutive CRT patients with both DCM and complete left bundle branch block (CLBBB) who received gated resting SPECT MPI at baseline were included in the present study. The phase analysis technique was applied on resting gated short-axis SPECT MPI images to measure systolic LVMD and diastolic LVMD, characterized by phase standard deviation (PSD) and phase histogram bandwidth (PBW). CRT response was defined as ≥ 5% improvement of LVEF at 6-month follow-up. Variables withP

AbstractAimsThis multicentre observational study aimed to prospectively assess the efficacy of left bundle branch area pacing (LBBAP) in heart failure patients with left bundle branch block (LBBB) and compare the 6 ‐month outcomes between LBBAP and biventricular pacing (BVP).Methods and resultsConsecutive patients with LBBB and left ventricular ejection fraction (LVEF)  ≤ 35% were prospectively recruited if they had undergone LBBAP as a primary or rescue strategy from three separate centres from March to December 2018. Patients who received BVP in 2018 were retrospectively selected by using 2 to 1 propensity...

AbstractPurpose of ReviewCardiac resynchronization therapy (CRT) is an established modality for treating heart failure. However, one-third of patients do not respond and it is increasingly recognized that response is not binary and we should be aiming for “best response”. This review looks at factors predicting response and remodelling and highlights areas where we may improve both the proportion of responders but also maximize response in an individual.Recent FindingsWe review the clinical characteristics predicting response including structural and electrical remodelling and discuss areas of debate. We examin...

AbstractAimsDespite previous surveys regarding device implantation rates in heart failure (HF), insight into the real ‐world management with devices is scarce. Therefore, we investigated device implantation rates in HF with reduced left ventricular ejection fraction (LVEF) in 34 Dutch centres.Methods and resultsA cross ‐sectional outpatient registry was conducted in 6666 patients with LVEF
