Abstract Background Edoxaban, a direct oral anticoagulant (DOAC), is first-line treatment for venous thromboembolism (VTE) and the suppression of VTE recurrence. In patients with cancer, however, recurrent after DOAC may be more common than in noncancer patients. To evaluate our hypothesis that anticoagulation effect edoxaban lower cancer Methods This study was prospective, multicenter, observational including treated Japan. The primary outcome difference prothrombin time (PT), activated...
Fragmented QRS complexes (fQRS) in the right precordial leads are associated with occurrence of ventricular fibrillation (VF) Brugada syndrome. Recently, epicardial mapping has revealed abnormal electrograms at (RV) outflow tract and inferior region ventricle. fQRS may reflect extent area potentials, but whether distribution prognostic value is not known.We evaluated existence 456 patients syndrome, including 117 syncope 23 VF. The was defined as (II, III, aVF), lateral (I, aVL, V5 V6),...
Abstract Introduction New onset of ventricular fibrillation (VF) in asymptomatic patients with Brugada‐type ECG is not frequent, but it cannot be negligible. Risk markers for predicting VF are usually based on results analysis symptomatic patients, and they have been determined patients. We analyzed Brugada syndrome to differentiate the risk factors both Methods The subjects were 471 we divided into two groups: Asymptomatic group (n = 326) Symptomatic (syncope: n 122, VF: 23). following...
Abstract Introduction The aim of the present study was to investigate impact time interval from collapse return spontaneous circulation (CPA-ROSC) in cardiac arrest patients and types who will benefit therapeutic hypothermia. Methods Four hundred witnessed adult comatose survivors out-of-hospital etiology were enrolled study. favorable neurological outcome defined as category 1 or 2 on five-point Pittsburgh cerebral performance scale at hospital discharge. A matching process based propensity...
Background A drug provocation test using a sodium channel blocker ( SCB ) can unmask type 1 ECG pattern in patients with Brugada syndrome. However, the prognostic value of results an challenge is limited non–type . We investigated associations future risk for ventricular fibrillation ‐induced changes and tachyarrhythmias VTA s). Methods Results administered intravenous pilsicainide to 245 consecutive syndrome (181 spontaneous , 64 ). parameters before after occurrence drug‐induced s were...
Background Sinus tachycardia during exercise attenuates ST‐segment elevation in patients with Brugada syndrome, whereas augmentation after an test is a high‐risk sign. Some have premature ventricular contractions (PVCs) related to exercise, but the significance of exercise‐related PVCs syndrome still unknown. The objective this study was determine for predicting occurrence fibrillation (VF) syndrome. Methods and Results subjects were 307 who performed treadmill test. We evaluated at rest,...
Abstract Background Remote monitoring (RM) has been advocated as the new standard of care for patients with cardiovascular implantable electronic devices (CIEDs). RM allowed early detection adverse clinical events, such arrhythmia, lead failure, and battery depletion. However, failure was often identified only by arrhythmic but not impedance abnormalities. Objective To compare usefulness events conventional abnormalities identifying in CIED followed RM. Methods 12 hospitals have center...
To establish the indication for programmed ventricular stimulation (PVS) asymptomatic patients with Brugada syndrome (BrS), we evaluated prognostic significance of PVS based on abnormal electrocardiogram (ECG) markers.One hundred and twenty-five BrS were included. We performed at two sites right ventricle up to three extrastimuli [two pacing cycle lengths minimum coupling interval (MCI) 180 ms]. followed 133 months fibrillation (VF) events. Fragmented QRS (fQRS) Tpeak-Tend (Tpe) as ECG...
Abstract Background The increase in the use of cardiac implantable electronic devices ( CIED s) has been associated with an ‐related infections. Transvenous lead extraction is safe and effective for patients infections; however, mortality rate these high. prognosis after transvenous Japanese patients, especially those lead‐related infective endocarditis, not evaluated. Then, purpose this study to clarify infections at a single center. Methods A total 107 who underwent were retrospectively...
One of the possible causes bone cement implantation syndrome during total hip arthroplasty is pulmonary embolism, as has been suggested by a characteristic image seen transoesophageal echocardiography, so‐called ‘Snow Flurry’. However, nature embolic material not definitively determined. We studied seven patients undergoing cemented or uncemented arthroplasty. Flurry’ images were detected in all patients. Blood was aspirated from right atrium Flurries’ and subjected to pathological...
To report rare cases of isolated medial orbital wall blow-out fractures and to evaluate their coronal CT findings.Nine fractures, diagnosed by in a general medical hospital between 1995 1999, were studied. was performed using direct acquisition with slice thickness 5 mm. Images obtained at bone window settings. Clinical examination findings from the records used give information on cause injury, ocular symptoms days after injury that performed.Most patients (67%) young male adults. The most...
Key Teaching Points•Short QT syndrome (SQTS) is a rare inherited arrhythmic disease and cause of sudden cardiac death (SCD). Implantable cardioverter-defibrillator (ICD) can prevent SCD in SQTS.•Quinidine reduce ICD therapy for ventricular fibrillation (VF) SQTS. If quinidine fails to multiple therapy, more advanced therapeutic option should be considered.•Recording premature complexes (PVCs) that trigger VF 12-lead electrocardiography will result success radiofrequency catheter ablation...
Objective Remote monitoring (RM) of cardiac implantable electric devices (CIEDs) has been advocated as a healthcare standard. However, expert consensus statements suggest that all patients require annual face-to-face follow-up consultations at outpatient clinics even if RM reveals no episodes. The objective this study was to determine the critical event rate after CIED implantation through RM. Methods This multicenter, retrospective, cohort evaluated with pacemakers (PMs), cardioverter...
Background The appearance of complete right bundle‐branch block (CRBBB) in Brugada syndrome (BrS) is associated with an increased risk ventricular fibrillation. pathophysiological mechanism CRBBB patients BrS has not been well established. We aimed to clarify the significance a conduction delay zone arrhythmias on using body surface mapping BrS. Methods and Results Body was recorded 11 8 control both CRBBB. transiently exhibited by unintentional catheter manipulation (proximal RBBB)....
