H1N1-associated sinus node dysfunction [PDF]

Heart Asia, 2015
A 51-year-old previously healthy man presented to the emergency room following an episode of presyncope. He had a history of fever, pleuropericardial chest pain and dyspnoea accompanied by important myalgia evolving over several days. His past medical history was negative for any cardiovascular or pulmonary disease, and he was a lifelong non-smoker. He

Cardiac Device Algorithms for Optimal Outcomes in Patients with Sick Sinus Syndrome [PDF]

, 2013
Sick sinus syndrome (SSS) is a relatively common chronic condition affecting the electrical conduction system of the heart. In the absence of any reversible cause of SSS, the most effective treatment is implantation of a permanent pacemaker to maintain ...

Extent of Sinus Surgery Is Associated With Disease Control in Biologic Treated Type 2 Dominant CRS

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background A greater benefit of biologics is observed after surgery in Type 2 chronic rhinosinusitis with nasal polyps (CRSwNP). However, the extent of surgery remains undefined in many studies. This study evaluated the extent of surgery on disease control in patients receiving biologics for refractory Type 2 dominant CRSwNP.

Cerebrovascular Events in Aortic Stenosis: From Native Valve Disease to TAVR‐Specific Risk and Prevention

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Aortic stenosis (AS) is associated with a heightened burden of cardiovascular comorbidities, atrial fibrillation (AF), and progressive valvular calcification, all of which may contribute to cerebrovascular events across the disease continuum.

Modifications to the cavopulmonary anastomosis do not eliminate early sinus node dysfunction

, 2000
Objective: To determine whether operations that theoretically jeopardize the sinus node (hemi-Fontan and/or lateral tunnel Fontan procedures) are associated with a greater risk of sinus node dysfunction than those that theoretically spare the sinus node (

Transthyretin amyloid cardiomyopathy: Literature review and red‐flag symptom clusters for each cardiology specialty

ESC Heart Failure, Volume 12, Issue 2, Page 955-967, April 2025.
Abstract Wild‐type transthyretin amyloid cardiomyopathy (ATTRwt‐CM) is a progressive and infiltrative cardiac disorder that may cause fatal consequences if left untreated. The estimated survival time from diagnosis is approximately 3–6 years. Because of the non‐specificity of initial symptom manifestation and insufficient awareness among treating ...

Platelet-bioengineered hiPSC-sEVs achieve targeted repair of fibrotic sinoatrial node in preclinical SND models

Nature Communications
Sinus node dysfunction, a prevalent arrhythmia in aging populations, is characterized by fibrosis and loss of pacemaker activity, necessitating pacemaker implantation. Current therapies fail to reverse the underlying pathology.

Intrinsic Versus Extrinsic Sinus and Atrioventricular Nodes Dysfunction in Athletes: Insights From Transesophageal Electrophysiological Testing With Autonomic Blockade

Reviews in Cardiovascular Medicine
Background: While sinus bradycardia and atrioventricular (AV) block in athletes have traditionally been viewed as benign consequences of enhanced vagal tone, recent evidence suggests that, in some individuals, nodal dysfunction may be ...

Genetic Na+ channelopathies and sinus node dysfunction

, 2008
Voltage-gated Na+ channels are transmembrane proteins that produce the fast inward Na+ current responsible for the depolarization phase of the cardiac action potential. They play fundamental roles in the initiation, propagation, and maintenance of normal
