BACKGROUND: The optimal duration of anticoagulation therapy for isolated distal deep vein thrombosis in patients with cancer is clinically relevant, but the evidence lacking. prolonged could have a potential benefit prevention thrombotic events; however, it also increase risk bleeding. METHODS: In multicenter, open-label, adjudicator-blinded, randomized clinical trial at 60 institutions Japan, we randomly assigned thrombosis, 1-to-1 ratio, to receive either 12-month or 3-month edoxaban...
Pulmonary arteriovenous malformation (PAVM) is a rare cause of embolic stroke undetermined source (ESUS) and can be challenging to diagnose promptly. In this case, woman in her 40s with ESUS was diagnosed PAVM after transoesophageal echocardiography (TOE) microbubble test revealed bubbles flowing from the right superior pulmonary vein. Endovascular treatment performed, follow-up transthoracic showed no right-to-left shunt, confirming successful shunt closure. This case significant as it...
Background: Due to advancements in cardiovascular intervention technologies, transesophageal echocardiography (TEE) is increasingly used. In Japan, nurse practitioners are being integrated into specialized procedures, including TEE, under physician supervision address shortages and improve patient safety. Methods: Consecutive patients undergoing TEE at our outpatient clinic from July 2022 June 2023 were included, with baseline characteristics, procedural details, outcomes retrospectively...
Abstract The media, a primary layer of the aortic wall, is rich in smooth muscle cells (SMCs) that regulate vessel diameter and maintain mechanical balance ring vivo. Embedded medial extracellular matrix, SMCs adapt to their surrounding environment via cyclic stretch during vascular contraction relaxation. Thus, circumferential stress constantly acts on hypertensive aorta expected further increase with increasing blood pressure (hypertension), resulting thickened wall. This thickening...
The aim of this study was to investigate the relationship between J-wave dynamics and arrhythmias during myocardial ischaemia in patients with vasospastic angina (VSA).Sixty-seven consecutive diagnosed VSA by a provocation test for coronary spasm were grouped according whether they had J wave baseline electrocardiograms or not (VSA-JW group, n = 14; VSA-non-JW group: 53). We retrospectively studied associations ST-segment induced ventricular fibrillations (VFs) spasm. In VSA-JW 7 14 showed...
Macroreentrant atrial tachycardia (MRAT) has been described most frequently in patients with prior cardiac surgery. Left and flutter are common who undergo fibrillation ablation; however, few reports describe left MRAT involving the regions of spontaneous scarring. Here, we without surgery or catheter ablation (CA) discuss clinical electrophysiological characteristics outcome CA.An study CA were performed 6 (3 men; age 76 ± years) originating from anterior wall (LAAW). No patient had a...
Abstract Aims Cardiac power output (CPO) measures cardiac performance, and its prognostic significance in heart failure with preserved ejection fraction (EF) has been previously reported. However, the effectiveness of CPO risk stratification patients valvular disease post-operative not We aimed to determine association between clinical outcomes left ventricular (LV) EF after transcatheter aortic valve implantation (TAVI). Methods results This retrospective observational study included 1047...
Abstract Weather conditions affect the incidence of acute myocardial infarction (AMI). However, little is known on association weather temperature and humidity with AMI hospitalizations in a super-aging society. This study sought to examine this association. We included 87,911 consecutive patients admitted Japanese acute-care hospitals between April 1, 2012 March 31, 2015. The primary outcome was number per day. Multilevel mixed-effects linear regression models were used estimate average...
Antiviral treatment is recommended for chronic hepatitis C patients with advanced fibrosis to reduce and prevent cirrhosis-related complications.To evaluate the efficacy safety of telaprevir (TVR)-based triple therapy in a clinical practice setting.This prospective, multicentre study consisted 102 (METAVIR score F3-4) who were infected HCV genotype 1b. All received 12 weeks TVR combination 24 pegylated interferon (PEG-IFN) α2b ribavirin (RBV).The sustained virological response (SVR) rate was...
Serum alkaline phosphatase was found to be higher in most cases between 2 and 26 weeks of age a line bred for high than random control line. The level the male female during growing period, but lower at later ages. There were no differences due or sex hatching.
Background: Patients with appropriately selected low-risk pulmonary embolism (PE) can be treated at home, although it has been controversial whether applies to patients cancer, who are considered not low risk.
Weather temperatures affect the incidence of cardiovascular diseases (CVD), but there is limited information on whether CVD hospitalizations are affected by changes in weather a super-aging society. We aimed to examine association diurnal temperature with hospitalizations. included 1,067,171 consecutive patients who were admitted acute-care hospitals Japan between April 1, 2012 and March 31, 2015. The primary outcome was number per day. range (DTR) defined as minimum subtracted from maximum...
Weather conditions influence the incidence of cardiovascular disease. However, few studies have investigated association between weather temperature and humidity cerebrovascular disease hospitalizations in a super-aging society. We included 606,807 consecutive patients with admitted to Japanese acute-care hospitals 2015 2019. The primary outcome was number per day. Multilevel mixed-effects linear regression models were used estimate mean humidity, 1 day before hospital admission,...
Abstract Introduction: Previous studies have shown that atrial fibrillation (AF) recurrence after pulmonary vein (PV) isolation depends on various factors; however, the effect of cigarette smoking AF PV has not been investigated. Methods and Results: Fifty‐nine consecutive patients with drug‐refractory (48 men 11 women, mean age: 60 ± years) who underwent were included. The divided into two groups: non‐smoker group, i.e., “never smokers (n = 29),” smoker group consisting 30 either “former...
AimsChronic obstructive pulmonary disease (COPD) is one of the important underlying diseases atrial fibrillation (AF). However, prevalence and electrophysiological characteristics typical flutter (AFL) in patients with AF COPD remain unknown. The purpose present study was to investigate those characteristics.
Abstract Although exposure to particulate matter with aerodynamic diameters ≤ 2.5 µm (PM ) influences cardiovascular disease (CVD), its association CVD-related hospitalizations of super-aged patients in Japan remains uncertain. We investigated the relationship between short-term PM and hospitalizations, lengths hospital stays, medical expenses. analyzed Japanese national database CVD (835,405) admitted acute-care hospitals 2012 2014. Patients planned those missing data were excluded....

Background: Fragmented QRS (fQRS) can predict cardiac events, and inducible ventricular tachycardia/fibrillation (VT/VF) is a known high-risk factor for arrhythmic death. However, whether fQRS predictor of events in patients with VT/VF unknown. We aimed to evaluate structural heart disease VT/VF. Methods Results: retrospectively investigated 98 who had defibrillator device implanted. All underwent electrophysiological testing prior or after implantation was induced. present 30 patients....
