Atrial fibrosis may act as a substrate for atrial fibrillation (AF) and functional mitral regurgitation (MR); thus, recognition is required to select the optimal therapeutic intervention. We examined clinical data from 1045 consecutive patients in three centers who underwent catheter ablation persistent AF between 2020 2022. 75 met moderate severe MR criteria completed 1-year follow-up. Voltage mapping during procedure was reviewed classify extent of fibrosis. Significant found 34 (45.3%),...
ABSTRACT We report a case of 21‐year‐old female manifesting narrow QRS complex tachycardia and alternating R‐R intervals. The fixed RP interval suggested ventriculoatrial conduction via an accessory pathway (AP). PR intervals indicated anterograde through the fast slow nodal pathways, respectively. coexistence AP dual atrioventricular pathways is not rare, with most them exhibiting as reentry (AVRT) using or exclusively limb. propose that AVRT may occur when pathway's effective refractory...
Chromatic optical waveguides are embedded into a 3D printed prosthetic finger to realize the fingertip tactile sensing capabilities of object contour, slip, hardness, and temperature, which enables complex functions such as note-writing analysis braille recognition.
Carrying out status monitoring and fault-diagnosis research on cutter-wear is of great significance for real-time understanding the health Tunnel Boring Machine (TBM) equipment reducing downtime losses. In this work, we proposed a new method to diagnose abnormal wear state disc cutter by using brain-like artificial intelligence process analyze vibration signal in dynamic contact between rock. This mainly aimed at realizing diagnosis identification cutter, not accurate measurement amount. The...
Elderly patients with coronary artery disease (CAD) frequently complicated more cardiovascular risk factors, but received fewer evidence-based medications (EBMs). This study explored the association of EBMs compliance in different age groups and long-term death. A retrospective analysis was conducted from a single registered database. 2830 consecutive CAD were enrolled grouped into 3 categories by age. The primary end point all-cause mortality secondary endpoint is mortality. mean follow-up...
Left ventricular hypertrophy (LVH) is prevalent in obese individuals. Besides, both of LVH and obesity associated with subclinical LV dysfunction. The study aims to investigate the interplay between body fat relation all-cause death patients coronary artery disease (CAD).In this retrospective cohort study, a total 2243 angiographically proven CAD were included. Body mass calculated using established formulas. Patients grouped according percentage presence or absence LVH. Cox-proportional...
Abstract Introduction The optimized ablation index (AI) value for catheter of atrial fibrillation (AF) remains to be defined. We aimed compare the efficacy and safety CLOSE protocol lower AI in paroxysmal AF. Methods Results Patients with symptomatic, drug‐resistant AF first were prospectively enrolled from September 2020 January 2022. patients randomly divided into group (AI ≥ 550 anterior/roof segments ≥400 posterior/inferior segments) 450 ≥350 segments). First‐pass isolation, acute...
Intracardiac echocardiography (ICE) has been used to guide radio-frequency catheter ablation (RFCA) for better navigation and less radiation exposure in treating atrial fibrillation (AF). This retrospective cohort study enrolled 227 AF patients undergoing ICE- or traditional fluoroscopy (TF)-guided RFCA a tertiary hospital. ICE was more often with tachycardia [odds ratio (OR) 3.692, p = 0.062], higher score of Hypertension, Abnormal renal/liver function, Stroke, Bleeding history...
Whether body composition is associated with the N-terminal pro-B-type natriuretic peptide (NT-proBNP) level and its prognostic performance in acute coronary syndrome (ACS) remains unknown. We aimed to investigate influence of on NT-proBNP among ACS patients. In total, 1623 patients data were enrolled. Percent fat lean mass index estimated using Clínica Universidad de Navarra—Body Adiposity Estimator equation. Patients divided into three groups according tertiles sex-specific index, percent...
Objectives: It is clinically important to evaluate the performance of a newly developed blood pressure (BP) measurement method under different conditions. This study aims using deep learning-based measure BPs and BP change non-resting conditions.Materials methods: Forty healthy subjects were studied. Systolic diastolic (SBPs DBPs) measured four conditions learning manual auscultatory method. The agreement between determined by two methods analysed changes was finally evaluated.Results: There...
To analyse the characteristics and mortality of hypertrophic cardiomyopathy (HCM) patients with different body compositions.In this study, 530 consecutive HCM at West China Hospital were studied from November 2008 to May 2016. An equation based on mass index (BMI) was used obtain Percent fat (BF) lean (LMI). Patients divided into five sex-specific BMI, BF LMI quintiles.The average 23.1 ± 3.2 kg/m2, 28.1 7.3% 16.5 2.2 respectively. higher BMI or older had more symptoms adverse cardiovascular...
