BACKGROUND Triple antithrombotic therapy increases the risk of bleeding events in patients undergoing percutaneous coronary intervention. However, it remains unclear whether good control of percent time in therapeutic range is associated with reduced occurrence of bleeding complications in patients undergoing triple antithrombotic therapy. METHODS AND(More)
BACKGROUND Even with a low energy setting, radiofrequency energy applications on the left atrial (LA) posterior wall may cause excessive transmural injury (ETI) during catheter ablation of atrial fibrillation (AF). OBJECTIVE The purpose of this study was to clarify the prevalence and characteristics of ETI. METHODS This study included 104 patients with(More)
BACKGROUND Chronic kidney disease (CKD) is often associated with atrial fibrillation (AF). However, its impact on the results of radiofrequency catheter ablation for AF has not been fully examined. OBJECTIVE The purpose of this study was to clarify the relationship between CKD and postcatheter ablation AF recurrence. METHODS The study included 221(More)
BACKGROUND Our study aimed to investigate both the clinical implications of late gadolinium enhancement (LGE) by cardiovascular magnetic resonance (CMR) and the relation of LGE to clinical findings in patients with Takotsubo cardiomyopathy (TTC). METHODS We evaluated 20 consecutive patients (2 men, 18 women; median age, 77 years; interquartile range [IQR](More)
BACKGROUND Recent evidence has linked early repolarization (ER) to idiopathic ventricular fibrillation (VF) in patients without structural heart disease. However, no studies have clarified whether or not there is an association between ER and the VF occurrences after the onset of an acute myocardial infarction (AMI). METHODS AND RESULTS This study(More)
BACKGROUND Insulin resistance is frequently present in obesity and during the development of type 2 diabetes mellitus. OBJECTIVE The purpose of the present study was to investigate the effect of electroacupuncture (EA) on high-fructose diet (HFD)-induced insulin resistance. METHODS Male Wistar rats were fed HFD for 4 weeks and developed insulin(More)
BACKGROUND Recent studies have suggested an emerging link between obstructive sleep apnea (OSA) and atrial fibrillation (AF). Patients with OSA are less likely to remain in sinus rhythm after radiofrequency catheter ablation of AF. OBJECTIVE To evaluate the efficacy of appropriate treatment with continuous positive airway pressure (CPAP) on recurrences of(More)
BACKGROUND Obstructive sleep apnea (OSA) is often associated with atrial fibrillation (AF), but the impact of radiofrequency catheter ablation (RFCA) for AF on sleep apnea syndrome is unknown. METHODS AND RESULTS A total of 25 patients (3 women; 61 ± 6 years) with sleep apnea syndrome who underwent RFCA for drug-refractory, persistent AF were studied.(More)
BACKGROUND Hyperthyroidism is usually regarded as a reversible cause of atrial fibrillation (AF); however, one-third of patients remain in AF despite euthyroid restoration. We hypothesized that a significant number of AF patients with hyperthyroidism (Hyperthyroid-AF) as well as those without (Non-thyroid-AF) would benefit from catheter ablation of AF (AF(More)
