Association of COPD with adverse outcomes in heart failure patients with preserved ejection fraction

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 799-808, April 2025.
Abstract We performed a systematic review and meta‐analysis to detect the impact of chronic obstructive pulmonary disease (COPD) on the prognosis of heart failure patients with preserved ejection fraction (HFpEF). We systematically screened eligible literature from three electronic databases, PubMed, EMBASE and Cochrane Library, up to April 2023.

The contribution of ionic currents to changes in refractoriness of human atrial myocytes associated with chronic atrial fibrillation [PDF]

open access: yes, 2001
<b>Objective:</b> To investigate changes in human atrial single cell functional electrophysiological properties associated with chronic atrial fibrillation (AF), and the contribution to these of accompanying ion current changes.

Commonalities of platelet dysfunction in heart failure with preserved ejection fraction and underlying comorbidities

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1013-1028, April 2025.
Abstract Heart failure with preserved ejection fraction (HFpEF) is characterized by a lack of a specific targeted treatment and a complex, partially unexplored pathophysiology. Common comorbidities associated with HFpEF are hypertension, atrial fibrillation, obesity and diabetes.

Oral Bisphosphonates and Risk of Atrial Fibrillation and Flutter in Women: A Self-Controlled Case-Series Safety Analysis [PDF]

open access: yes, 2009
Background: A recent trial unexpectedly reported that atrial fibrillation, when defined as serious, occurred more often in participants randomized to an annual infusion of the relatively new parenteral bisphosphonate, zoledronic acid, than among those ...

FDG PET/CT imaging and circulating biomarkers of inflammation in desmoplakin cardiomyopathy

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1485-1489, April 2025.
Abstract Aims Inflammation has been implicated in the pathogenesis of desmoplakin (DSP) cardiomyopathy, and retrospective studies have described abnormal myocardial fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) findings in symptomatic patients eventually diagnosed with DSP cardiomyopathy.

Revisiting the concept that interictal implies asymptomatic: Pulse wave amplitude drops uncover autonomic responses during generalized paroxysmal fast activities

open access: yesEpilepsia, EarlyView.
Abstract Objective Interictal electroencephalographic (EEG) activities are generally considered asymptomatic. Pulse wave amplitude drop (PWAD) is a marker of autonomic nervous system (ANS) reactivity linked to cardiovascular risk. Generalized paroxysmal fast activity (GPFA) is a major EEG pattern in different epileptic conditions.

Clinical approach to paroxysmal atrial fibrillation [PDF]

open access: yesClinical Cardiology, 1990
AbstractIn addition to the role of the electrophysiological substrate, paroxysmal atrial fibrillation depends on the modulation of the atrial tissues by the autonomic nervous system. Experimentally, models of atrial fibrillation can be based on either adrenergic or vagal stimulations that provoke the arrhythmia by disturbing in a different way ...

Duration of heart failure and the risk of atrial fibrillation: different mechanisms at different times? [PDF]

open access: yes, 2009
Chronic heart failure increases the risk of atrial fibrillation (AF), with the prevalence of AF paralleling the severity of heart failure.1 Factors that underlie this increased susceptibility to AF may include electrical, structural, and neurohumoral ...

Exercising electrocardiograms from Thoroughbred racehorses with exercise associated sudden death

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Exercise associated sudden death (EASD), defined as a fatal collapse in a closely monitored and previously presumed clinically healthy horse that occurs during exercise or within approximately 1 h after exercise, is disproportionately more common in equine than in human athletes.

The G protein-gated potassium current I(K,ACh) is constitutively active in patients with chronic atrial fibrillation [PDF]

open access: yes, 2005
Background— The molecular mechanism of increased background inward rectifier current (IK1) in atrial fibrillation (AF) is not fully understood. We tested whether constitutively active acetylcholine (ACh)-activated IK,ACh contributes to enhanced basal ...
