Premature senescence is associated with atrial fibrosis and has an antifibrotic effect in mice. However, the role of senescence in atrial fibrillation (AF) remains unclear. Here, we investigated the association of premature senescence with fibrosis and also determined the role of senescence in the recurrence of AF after surgery ablation. Western blot, Sirius red staining, SA-β-gal staining and immunohistochemistry were performed to detect the degree of atrial fibrosis ,the expression of TGF-β and collagens, and also the senescence markers in 72 tissue specimens of left atrial appendage in this study...

: Vascular malformation is occasionally complicated by consumptive coagulopathy, known as localized intravascular coagulopathy (LIC), which is characterized by a reduced fibrinogen level, an elevated D-dimer level and a normal platelet count. We report the case of a 17-year-old Japanese girl who presented with LIC secondary to extensive vascular malformations, whose condition had progressed to disseminated intravascular coagulation (DIC). She suddenly presented with severe anaemia, despite the absence of obvious bleeding, and she began to require regular red blood cell (RBC) transfusions...

The patient population with the need for oral anticoagulation to reduce stroke risk associated with atrial fibrillation (AF) and dual antiplatelet therapy to prevent stent thrombosis and myocardial infarction after percutaneous coronary intervention is increasing. However, patients treated with a triple therapy consisting of oral anticoagulation, aspirin, and a P2Y12 inhibitor have been demonstrated to be at high bleeding risk. The best combination of these agents and the duration of the different therapies are still uncertain...

: A huge thrombus, developing after percutaneous left atrial appendage occlusion, has been successfully treated with dabigatran and aspirin as combination therapy.Although novel oral anticoagulants alone may be effective in thrombus dissolution, the association of an antiplatelet drug may safely enhance this process.

We report the unexpected transesophageal echocardiography (TEE) finding of a left atrial (LA) thrombus near the end of cardiopulmonary bypass and after deployment of an AtriClip (Atricure, Inc, Westchester, OH) in an 84-year-old man with atrial fibrillation and aortic stenosis undergoing aortic valve replacement and LA appendage ligation. TEE examination before cardiopulmonary bypass and deployment of the AtriClip had not shown a thrombus in the LA appendage. The heart was rearrested and thrombus was successfully removed through a left atriotomy...

AIM: Recently, digoxin use has been found to associate with higher mortality. Yet, potential mechanisms by which digoxin use increases mortality remain unclear. Increased arrhythmogenicity from digoxin use is one possibility. Thus, we aimed to evaluate the relation between digoxin and shock events in patients with implantable cardioverter defibrillators (ICDs). METHODS: We performed a retrospective chart review of all patients with ICDs and at least 1 device interrogation at our institution between January 1, 2012, and January 1, 2015...

Atrial fibrillation (AF) is a common cardiac arrhythmia with significant clinical outcomes, and is associated with high medical and social costs. AF is complicated for patients because of its specialised terminology, long-term adherence, symptom monitoring, referral to specialty care, array of potential interventions and potential for adversity. Health literacy is a frequently under-recognised, yet fundamental, component towards successful care in AF. Health literacy is defined as the capacity to obtain, process and understand health information, and has had markedly limited study in AF...

Very-low-density lipoproteins (VLDL) is a hallmark of metabolic syndrome (MetS) and each manifestation of MetS is related to atrial fibrillation (AF) risks. Slowed atrial conduction is a mechanism of AF in MetS. We hypothesized that VLDL can modulate and reduce atrial gap junctions. VLDLs were separated from normal (Normal-VLDL) and MetS (MetS-VLDL) individuals. VLDLs (15 µg/g) and equivalent volumes of saline (CTL) were injected respectively to C57BL/6 mice for 6 weeks. Electrocardiograms demonstrated that MetS-VLDL induced prolongation of P wave (P = 0...

Bleeding risk with vitamin K antagonists (VKAs) is closely related to the quality of anticoagulation in atrial fibrillation (AF) patients, reflected by time in therapeutic range (TTR). Here we compared the discrimination performance of different bleeding risk scores and investigated if adding TTR would improve their predictive value and clinical usefulness. We included 1361 AF patients stables on VKA for at least 6 months. Bleeding risk was assessed by the HAS-BLED, ATRIA, ORBIT and HEMORR2HAGES scores. Major bleeding events were recorded after a median of 6...

BACKGROUND: The global real-life impact of non-vitamin K antagonist oral anticoagulants (NOACs) introduction in the healthcare system in a setting of well-managed vitamin K antagonist (VKA) therapy has not been specifically addressed. METHODS: We did a population-based retrospective cohort study in naïve patients initiating oral anticoagulants for stroke prevention in atrial fibrillation in a region with a well-managed VKA therapy. NOAC and VKA cohorts were identified using Anatomical Therapeutic Chemical (ATC) codes, while excluding other indications for anticoagulation therapy using ICD-9CM codes...

BACKGROUND: Guidelines recommend long-term oral anticoagulation therapy for stroke prevention in patients with atrial fibrillation (AF). Treatment discontinuation rates in vitamin K antagonist (VKA)-treated patients are high but may be lower with non-VKA oral anticoagulant agents. OBJECTIVES: The goal of this study was to describe and explore predictors of dabigatran etexilate persistence in patients with newly diagnosed AF over 2 years of follow-up. METHODS: Consecutive patients newly diagnosed with AF and ≥1 stroke risk factor were followed up for 2 years...

Aims: We report the maternal and foetal outcomes at birth and after 6 months in a cohort of pregnant women with hypertrophic cardiomyopathy (HCM). Although most women with HCM tolerate pregnancy well, there is an increased risk of obstetric and cardiovascular complications. Methods and results: All pregnant women with HCM entered into the prospective worldwide Registry of Pregnancy and Cardiac disease (ROPAC) were included in this analysis. The primary endpoint was a major adverse cardiovascular event (MACE), which included death, heart failure (HF), thrombo-embolic event, and arrhythmia...

Atrial fibrillation seems to be overrepresented among patients with primary aldosteronism. The aim of this study was to determine the usefulness of aldosterone to renin ratio as a screening instrument for primary aldosteronism in an atrial fibrillation population with relatively low cardiovascular risk profile. A total of 149 patients <65 years and with history of AF were screened for primary aldosteronism using aldosterone to renin ratio. Pathologically increased aldosterone to renin ratio (>65 pmol/mIU) was found in 15 participants (10...

BACKGROUND: Atrial fibrillation (AF) is a major contributor to the global cardiovascular disease burden. The clinical profile and outcomes of AF patients with valvular heart diseases in sub-Saharan Africa (SSA) have not been adequately described. We assessed clinical features and 12-month outcomes of patients with valvular AF (vAF) in comparison to AF patients without valvular heart disease (nvAF) in western Kenya. METHODS: We performed a cohort study with retrospective data gathering to characterize risk factors and prospective data collection to characterize their hospitalization, stroke and mortality rates...

microRNAs (miRNAs) are small non-coding RNAs, involved in regulation of post-transcriptional gene expression. They exert key role not only in physiology and normal development of the cardiovascular system but also in cardiovascular disease development and progression. Recent animal and human studies of tissue specific miRNAs have suggested a role in structural and electrical remodeling in atrial fibrillation (AF). Their emerging role as biomarkers and potential therapeutic targets in patients with AF is discussed in this review...
