Previous noninvasive measurements of the pulse waveform radial artery have not employed standard positioning procedures. Here, we propose a new measuring apparatus that has two-axis mechanism and employs procedure for detecting optimal site accurately pressure (PPW). A modified sensor was designed to simultaneously measure arterial diameter changed (ADCW) PPW. Considering as cylinder, measured would be distorted if were at middle width. Moreover, blood vessel is elastic, its compliance...
Acute ST-elevation myocardial infarction (STEMI) elicits a robust cardiomyocyte death and inflammatory responses despite timely revascularization.This phase 1, open-label, single-arm, first-in-human study aimed to assess the safety efficacy of combined intracoronary (IC) intravenous (IV) transplantation umbilical cord-derived mesenchymal stem cells (UMSC01) for heart repair in STEMI patients with impaired left ventricular ejection fraction (LVEF 30-49%) following successful reperfusion by...
Multiple intracardiac catheters are often necessary for electrophysiological study (EPS) and radiofrequency (RF) ablation therapy. Therefore, multiple venous sheath placement in one femoral vein is always required catheter insertion. The vascular complications incurred by of sheaths have not been fully studied. We utilized duplex ultrasonography to assess the veins before after procedure. This consisted 52 patients (68 veins) who underwent EPS RF Up three were inserted into a single vein....
Peripheral artery disease (PAD) is known to be an increased mortality risk in patients with end-stage renal (ESRD). The aim of this study was compare patient survival between subclinical PAD undergoing peritoneal dialysis (PD) and hemodialysis (HD). Subclinical peripheral defined as ankle-brachial index less than 0.9. This conducted from April 2005, the observation period ended on 30 June 2011. At end follow-up, status all assessed data were obtained for entire cohort. A total 91 (61 HD PD)...
The initiation of focal atrial tachycardia (AT) from the superior vena cava (SVC) remains unclear. In 3 patients (2 females, 1 male; aged 57, 66 and 50 years, respectively) with AT arising different parts SVC, occurred spontaneously, rather than being induced by electrical stimulation. cycle length was highly variable, ranging between 190 300 ms in patient 1, 180 320ms 2, 200 300ms 3. clinical or associated arrhythmias were fibrillation (AF) (patients 3) flutter (AFL) 3). A presumed SVC...
The health benefits of coixol, an active compound adlay seed, have attracted certain attention. Adlay seed is often adopted in traditional Chinese medicine for the treatment various inflammatory disorders. Thus, it hypothesized that coixol could protect neuronal cells.
Background It is well known that familial sick sinus syndrome (SSS) caused by functional alterations of ion channels and gap junction. Limited information available on the mechanism age-related non-familial SSS. Although evidence shows a close link between arrhythmia renin-angiotensin system (RAS), it remains to be determined whether RAS involved in pathogenesis Methods In this study, 113 patients with documented SSS 125 controls were screened for angiotensinogen (AGT) junction...
Familial sick sinus syndrome is associated with gene mutations and dysfunction of ion channels. In contrast, degenerative fibrosis the node tissue plays an important role in pathogenesis acquired syndrome. There a close relationship between transforming growth factor-β1 mediated cardiac arrhythmia. It interest to examine whether involved syndrome.Overall, 110 patients SSS 137 age/gender-matched controls were screened for sodium channel polymorphisms using sequencing or restriction fragment...
Abstract Impaired left atrial appendage ejection fraction (LAA-EF) and peak LAA flow velocity (LAA-FV) are associated with high thromboembolic risks in patients fibrillation (AF). Herein, we examined function among flutter (AFL) stratified by the CHA 2 DS -VASc score using transesophageal echocardiography (TEE). Of 231 consecutive typical AFL, 84 who fulfilled inclusion criteria were enrolled. Among them, 57 had ongoing AFL divided into isolated (n = 38) paroxysmal AF (PAF) 19) groups,...
Aim: Atrial fibrillation (AF) is characterized by the development of thromboembolic events and more prevalent among end-stage renal disease patients than in general population. Vascular access thrombosis (VAT) a major morbidity chronic hemodialysis (HD) patients; however, association between AF VAT unknown.Methods: We retrospectively reviewed HD with functional vascular 1997 2006. The was analyzed using Kaplan-Meier analysis multivariate Cox proportional hazards regression.Results: A total...
Abstract Limited studies are available regarding the pathophysiological mechanism of acquired atrioventricular block (AVB). Matrix metalloproteinases (MMPs) and angiotensin-converting enzyme (ACE) have been implicated in pathogenesis arrhythmia. However, relationship between these molecules AVB is still unclear. One hundred two patients with documented 100 controls were studied. Gene polymorphisms MMP1 ACE encoding genes screened by gene sequencing method or polymerase chain...
QRS duration has been associated with the response to cardiac resynchronization therapy (CRT).However, methods for defining predict outcome of CRT have discrepancies in previous reports.The aim this study was determine an optimal measurement CRT.Sixty-one patients who received were analyzed.All had class III-IV heart failure, left ventricular ejection fraction not more than 35%, and complete bundle branch block.The shortest, longest, average durations from 12 leads each electrocardiogram...
This report describes a patient who underwent implantation of an atriobiventricular pacemaker following AV junction ablation and insertion temporary right ventricular (RV) pacemaker. During implantation, intermittent loss sinus P wave tracking occurred when the three permanent leads were connected to generator. Analysis marker annotation disclosed abnormal sensing that reinitiated postventricular atrial blanking caused failure tracking. phenomenon disappeared after removing RV lead, but not...
<i>Introduction:</i> Cellular mechanisms of adenosine include a direct effect on the activation adenosine-sensitive potassium current (I<sub>K,Ado</sub>) and an indirect antagonism catecholamine-stimulated adenylate cyclase activity. However, previous studies evaluating influence catecholamine activity electrophysiologic effects have yielded conflicting results. We tested hypotheses that if exerts its atrioventricular (AV) nodal blocking directly by activating...
