Gender‐Related Safety and Efficacy of Cardiac Resynchronization Therapy

Abstract BackgroundCardiac resynchronization therapy (CRT) is an established therapy for patients with chronic heart failure (CHF) and a broad QRS complex. Gender‐related safety and efficacy data are necessary for informed patient decision‐making for female patients with CHF. The aim of the study was to assess the effects of gender on the outcome of CRT in highly symptomatic heart failure patients. HypothesisGender may have an effect on the outcome of heart failure patients undergoing cardiac resynchronisation therapy. MethodsThe study analyzed the 2‐year follow‐up of 393 New York Heart Association (NYHA) class III/IV patients with a class I CRT indication enrolled in the Management of Atrial Fibrillation Suppression in AF‐HF Comorbidity Therapy (MASCOT) study. ResultsIn female patients (n = 82), compared with male patients (n = 311), CHF was more often due to dilated cardiomyopathy (74% vs 44%, respectively; P

AbstractBackgroundTachycardia-induced cardiomyopathy (TCM) has been known for decades as a  reversible form of non-ischemic cardiomyopathy. However, its mechanism and characteristics remain poorly understood.ObjectivesThis retrospective study investigated endomyocardial biopsy (EMB) samples from consecutive patients with TCM and compared them with samples from patients with dilated cardiomyopathy (DCM) and inflammatory cardiomyopathy (InCM).Materials and methodsA total of 684 patients (18  TCM, 170 DCM, 496 InCM) with recent-onset heart failure and reduced ejection fraction unrelated to valvular or ischemic heart...

AbstractThe majority of patients hospitalized for heart failure (HF) are admitted to internal medicine (IM) rather than to cardiology (CA) units, but to date few studies have analyzed the characteristics of these two populations. In this snapshot survey, we compared consecutive patients admitted for HF in six IM units vs. one non-intensive CA unit. During the 6-month survey period, 467 patients were enrolled (127 in CA, 27.2% vs. 340 in IM, 72.8%). IM patients were almost 10  years older (CA 75 ± 10, IM 82 ± 8 years;p

ConclusionsIn DCM patients with LGE, characterised by progression of LV remodelling, the LGE pattern was a predictor of HF recurrence, whereas in patients without LGE, absence of autophagic vacuoles was a predictor of HF recurrence.

Conclusion In our experience, patients with RV dysfunction less likely benefited from CRT. RV assessment, studied with CMR, appears to be a good predictor of the response to biventricular stimulation.

In conclusion, α1-antitrypsin and lectin-like oxidized low-density-lipoprotein receptor-1 seem to represent two good markers in HF and therapeutic targets, whereas galectin-3 does not. PMID: 31782085 [PubMed - as supplied by publisher]

CONCLUSIONS: In BIOSTAT-CHF, patients with HF of an ischemic etiology, and those with worsening HF precipitated by renal failure (irrespective of the underlying HF etiology), had the highest rates of death and HF hospitalization, but still benefited equally from treatment up-titration.

In conclusion, AF seems to have a higher prevalence in the general population than previously thought, and is mostly associa ted with hypertension, cardiomyopathy and rheumatic heart disease in SSA. It is associated with a high incidence of heart failure and stroke. The management of AF is suboptimal in SSA, especially with a low uptake of oral anticoagulation.This article is protected by copyright. All rights reserved.

AbstractHeart diseases are a major cause of morbidity and mortality world-wide. Lysyl oxidase (LOX) and related LOX-like (LOXL) isoforms play a vital role in remodelling the extracellular matrix (ECM). The LOX family controls ECM formation by cross-linking collagen and elastin chains. LOX/LOXL proteins are copper-dependent amine oxidases that catalyse the oxidation of lysine, causing cross-linking between the lysine moieties of lysine-rich proteins. Dynamic changes in LOX and LOXL protein-expression occur in a variety of cardiac pathologies; these changes are believed to be central to the associated tissue-fibrosis. An awa...
