Longitudinal study of patients with chronic Chagas cardiomyopathy in Brazil (SaMi-Trop project): a cohort profile. [PDF]

, 2016
PurposeWe have established a prospective cohort of 1959 patients with chronic Chagas cardiomyopathy to evaluate if a clinical prediction rule based on ECG, brain natriuretic peptide (BNP) levels, and other biomarkers can be useful in clinical practice ...

Progression and prognostic significance of electrocardiographic findings in patients with cardiac amyloidosis

ESC Heart Failure, Volume 12, Issue 2, Page 809-818, April 2025.
Abstract Aims This study aimed to evaluate the change of the main electrocardiographic (ECG) characteristics and their prognostic role across the main subtypes of cardiac amyloidosis [light‐chain amyloidosis (AL) and hereditary (ATTRv) and wild‐type transthyretin amyloidosis (ATTRwt)].

Influence of Slippery Pacemaker Leads on Lead-Induced Venous Occlusion [PDF]

, 2017
The use of medical devices such as pacemakers and implantable cardiac defibrillators have become commonplace to treat arrhythmias. Pacing leads with electrodes are used to send electrical pulses to the heart to treat either abnormally slow heart rates ...

The difficult discussion on the deactivation of implantable cardioverter devices at the end of life: a systematic review

ESC Heart Failure, Volume 12, Issue 2, Page 733-760, April 2025.
Abstract Implantable cardioverter defibrillators (ICDs) reliably prevent death due to life‐threatening arrhythmias; this may become less relevant in people with more severe heart failure who are reaching the end of life (EOL). This review aimed to explore the ICD deactivation process and identify ethical issues, especially around the initiation of ...

Forecasting heart failure: Seasonal alignment of heart failure outcomes in New York

ESC Heart Failure, Volume 12, Issue 2, Page 819-831, April 2025.
Abstract Background Seasonal variations have been observed in heart failure (HF) hospitalization. Numerous explanatory mechanisms have been proposed, but no prior studies have examined potential contributors directly. Our objective was to identify specific factors that could contribute to seasonal variability using a large longitudinal dataset of HF ...

Identifying atrial arrhythmias versus pacing-induced rhythm disorders with state-of-the-art cardiac implanted devices

Journal of Arrhythmia, 2014
Repetitive non-reentrant ventriculo-atrial synchrony (RNRVAS) is a pacemaker-induced arrhythmia that must be distinguished from atrial fibrillation (AF). Pacemaker-induced arrhythmias are commonly detected as atrial high rate episodes (AHRE) by implanted

Genetically engineered cardiac pacemaker: stem cells transfected with HCN2 gene and myocytes - a model

, 2005
Artificial biological pacemakers were developed and tested in canine ventricles. Next steps will require obtaining oscillations sensitive to external regulations, and robust with respect to long term drifts of expression levels of pacemaker currents and ...

Incident heart failure: comparing management and outcome in primary and hospital settings in Western Sweden 2008–2017

ESC Heart Failure, Volume 12, Issue 2, Page 832-838, April 2025.
Abstract Aim Heart failure (HF) is a highly prevalent condition managed in both primary care (PC) and hospital care (HC)‐based settings. HF patients managed in these two settings may differ in their demography, comorbidities and outcomes, so we aimed to compare the patient management in PC and HC in the Västra Götaland Region (VGR) in Sweden.

Pacemaker pocket histoplasmosis – A rarest of rare CIED infection

Indian Pacing and Electrophysiology Journal
Cardiac Implantable Electronic Device infections continue to pose a pivotal threat to the successful management of various cardiac electrical disturbances. We present a case of a 79-year-old male who had undergone a dual-chamber pacemaker implantation 10
