Open AccessAssociations of combined polygenic risk score and glycemic status with atrial fibrillation, coronary artery disease and ischemic stroke
It is unknown whether high hemoglobin A1c (HbA1c) is associated with increases in the risk of cardiovascular disease among individuals with elevated genetic susceptibility. We aimed to investigate the associat...

Article
Open AccessAssociation between alcohol consumption and subclinical atrial fibrillation
It has become important to identify and manage risk factors for subclinical atrial fibrillation (AF) with an increase in its detection rate. Thus, this research aimed to investigate whether alcohol consumption...

Article
Open AccessResting heart rate and cardiovascular outcomes in patients with non-paroxysmal atrial fibrillation: CODE-AF registry
The prognostic significance of resting heart rate and its therapeutic target in atrial fibrillation (AF) is uncertain. We sought to investigate the relationship between resting heart rate and cardiovascular ou...

Article
Association of changes in cardiovascular health levels with incident cardiovascular events and mortality in patients with atrial fibrillation
Risk factor management is crucial in the management of atrial fibrillation (AF). We investigated the association of changes in cardiovascular health (CVH) levels after AF diagnosis with incident cardiovascular...

Open AccessLeft bundle branch area pacing with stylet-driven pacing leads: implantation technique
Traditional right ventricular apical pacing can cause electrical–mechanical dyssynchrony. Therefore, physiological conduction system pacing was considered and became the reason for develo** His bundle pacing...

Article
Open AccessMachine learning based potentiating impacts of 12-lead ECG for classifying paroxysmal versus non-paroxysmal atrial fibrillation
Conventional modality requires several days observation by Holter monitor to differentiate atrial fibrillation (AF) between Paroxysmal atrial fibrillation (PAF) and Non-paroxysmal atrial fibrillation (Non-PAF)...

Open AccessThe effect of age, gender, economic state, and urbanization on the temporal trend in sudden cardiac arrest: a nationwide population-based cohort study
Sudden cardiac arrest (SCA) has not been well studied in Asian countries. This study investigated the temporal trends in the incidence and outcomes of SCA and the impact of age, gender, economic state, and urb...

Article
Open AccessIn silico screening method for non-responders to cardiac resynchronization therapy in patients with heart failure: a pilot study
Cardiac resynchronization therapy (CRT) is an effective treatment option for patients with heart failure (HF) and left ventricular (LV) dyssynchrony. However, the problem of some patients not responding to CRT...

Article
Open AccessUsefulness of cardiac magnetic resonance images for prediction of sudden cardiac arrest in patients with mitral valve prolapse: a multicenter retrospective cohort study
An association has been identified between mitral valve prolapse (MVP) and sudden cardiac arrest (SCA), and ventricular arrhythmias (VA). This study aimed to elucidate predictive factors for SCA or VA in MVP p...

Article
Open AccessLower dementia risk with anticoagulation and ablation in patients with atrial fibrillation
Atrial fibrillation (AF), the most common cardiac arrhythmia in the elderly population, has been associated with an impairment of cognitive function and an increased risk of dementia. Even though there does no...

Article
Open AccessSubclinical cardiac perforation by cardiac implantable electronic device leads detected by cardiac computed tomography
The relationship between the characteristics of cardiac implantable electronic device (CIED) leads and subclinical cardiac perforations remains unclear. This study aimed to evaluate the incidence of subclinica...

Open AccessRisk for osteoporotic fractures in patients with atrial fibrillation using different oral anticoagulants
We aimed to investigate the comparative risk of fracture among patients with atrial fibrillation (AF) treated with warfarin or non-vitamin K antagonist oral anticoagulants (NOACs).

Article
Open AccessLong-term prognosis of short QT interval in Korean patients: a multicenter retrospective cohort study
Short QT syndrome is a rare, inherited channelopathy associated with sudden cardiac arrest (SCA) but the characteristics and prognosis of short QT interval (SQTI) in Korean patients remain unclear. This study ...

Article
Open AccessAccuracy and clinical feasibility of 3D-myocardial thickness map measured by cardiac computed tomogram
Although myocardial thickness is an important variable for therapeutic catheter ablation of cardiac arrhythmias, quantification of wall thickness has been overlooked. We developed a software (AMBER) that measu...

Article
Open AccessClinical and genetic relationships between the QTc interval and risk of a stroke among atrial fibrillation patients undergoing catheter ablation
A prolonged QTc interval is associated with an increased risk of a stroke or atrial fibrillation (AF). However, its direct causal relationship with AF associated a stroke has not been proven yet. To examine wh...

Article
Open AccessMultiple atrial premature contractions predict stroke recurrence in patients with cryptogenic stroke and concomitant non-sustained atrial tachycardia
Atrial fibrillation is a known risk factor for cryptogenic stroke and therefore requires early detection and prompt management. We investigated predictors of stroke recurrence in patients with cryptogenic stro...

Article
Open AccessDifferences in anticoagulation strategy and outcome in atrial fibrillation patients with chronic kidney disease: a CODE-AF registry study
Dose reduction of non-vitamin K antagonist oral anticoagulants (NOACs) is indicated in patients with atrial fibrillation (AF) with renal impairment. This study investigated anticoagulation patterns and outcome...

Article
Open AccessCharacteristics of symptom burden in atrial fibrillation with concomitant heart failure
Symptom burden is an important factor in determining the treatment of atrial fibrillation (AF). AF is frequently accompanied by heart failure (HF). This study investigated the characteristics of AF symptoms wi...

Article
Open AccessPost-operative left atrial volume index is a predictor of the occurrence of permanent atrial fibrillation after mitral valve surgery in patients who undergo mitral valve surgery
Atrial fibrillation (AF) can occur even after the correction of mitral valve (MV) pathology in patients who have pre-operative sinus rhythm and undergo MV surgery. However, the factors associated with the occu...
