Temporal association between drops in thoracic impedance and malignant ventricular arrhythmia: A longitudinal analysis of remote monitoring trends.

Introduction: Thoracic impedance (TI) drops measured by implantable cardioverter-defibrillators (ICDs) have been reported to correlate with ventricular tachycardia/fibrillation (VT/VF). The aim of our study was to assess the temporal association of decreasing TI trends with VT/VF episodes through a longitudinal analysis of daily remote monitoring data from ICDs and cardiac resynchronization therapy defibrillators (CRT-Ds).

Methods And Results: Retrospective data from 2384 patients were randomized 1:1 into a derivation or validation cohort.

Use and Prescription of Direct Oral Anticoagulants in Older and Frail Patients with Atrial Fibrillation: A Multidisciplinary Consensus Document.

In the last twelve years the clinical management of patients with atrial fibrillation has been revolutionised by the introduction of direct oral anticoagulants. Despite the large amount of evidence produced, some populations remain relatively poorly explored regarding the effectiveness and safety of direct oral anticoagulants, such as the oldest and/or frailest individuals. Frailty is clinical syndrome characterized by a reduction of functions and physiological reserves which results in individuals having higher vulnerability.

Rhythm-control vs rate-control in the elderly: When to do it and which drug to prefer?

Atrial fibrillation (AF) is a relevant cardiovascular condition that is more prevalent in the elderly patients aged over 65 years. AF, with abnormal rate and rhythm can cause symptoms directly or indirectly by exacerbating other frequently coexisting cardiac conditions such as valvular heart disease, hypertension, ischemic cardiomyopathy, dilated cardiomyopathy, and hypertrophic cardiomyopathy. Evidence suggests that aging-related cardiovascular changes predispose to the elderly to AF.
