23 Chronic heart failure (CHF) is responsible for significant morbidity and mortality worldwide, 24 mainly as a result of neurohumoral activation. Acupuncture has been used to treat a wide 25 range of diseases and conditions. In this study, we investigated the effects of 26 electroacupuncture (EA) on the sympathetic nerve activity, heart function and remodeling in 27 CHF rats after ligation of ...
OBJECTIVE The purpose of our study is to investigate cirrhosis-related left ventricular remodeling and functional changes, further to analyze the correlations with model for end-stage liver disease (MELD) score. METHODS A total of 89 cirrhotic patients were enrolled for study and subgrouped according to MELD score: ≤ 9, 10-19, and ≥ 20. Thirty healthy individuals were enrolled as controls. Al...
Dilated cardiomyopathy (DCM) or round heart disease is a muscle disease of the heart which is characterized by ventricular dilatation and abnormal systolic and diastolic left ventricular function. In animals, including turkeys and humans, DCM is the major cause of morbidity and mortality which results from heart failure. In the turkey, DCM can be idiopathic or induced. Since idiopathic or spont...
INTRODUCTION Mitral stenosis (MS) causes structural and functional abnormalities of the left atrium (LA) and left atrial appendage (LAA), and studies show that LAA performance improves within a short time after percutaneous transvenous mitral commissurotomy (PTMC). This study aimed to investigate the effects of PTMC on left atrial function by transesophageal echocardiography (TEE). METHODS We...
AIM The neural cardiac therapy for heart failure (NECTAR-HF) was a randomized sham-controlled trial designed to evaluate whether a single dose of vagal nerve stimulation (VNS) would attenuate cardiac remodelling, improve cardiac function and increase exercise capacity in symptomatic heart failure patients with severe left ventricular (LV) systolic dysfunction despite guideline recommended medic...
Changes in left ventricular size may be of importance in the development of angina and in its amelioration by glyceryl trinitrate, but left ventricular dimensions have not been measured during exercise in the upright position, the circumstance in which angina most often occurs. To assess changes in left ventricular end-systolic and end-diastolic dimensions, echocardiograms were obtained from 5 ...
BACKGROUND This study sought to evaluate the therapeutic effects of renal denervation (RDN) on acute myocardial infarction (MI) in canines and explore its possible mechanisms of action. METHODS Eighteen healthy mongrel dogs were randomly assigned to either the control group, the MI group or the MI + RDN group. To assess cardiac function, left ventricular ejection fraction (LVEF), left ventric...
The aim of the study was to investigate the cardiac magnetic resonance (CMR) imaging in interventional therapy of patients with acute myocardial infarction prior to and after treatment. Fifty-six cases of AMI patients with elective treatment by percutaneous coronary intervention (PCI) were continuously selected. Patients with an incidence of 7-10 days were treated with CMR and echocardiography ...
Background and Aim: Heart failure is one of the most prevalent diseases with high mortality and disability. Beta blockers are among basic drugs treating the disorder and leading to reduction in cardiovascular mortality, and improvement of symptoms and left ventricular function. Regarding the increasing prevalence of this disease, the present study was carried out to compare carvedilol with meto...
BACKGROUND Many asymptomatic patients with aorta regurgitation and normal left ventricular systolic function remain clinically stable for many years, but others ultimately develop symptoms or left ventricular dysfunction and require operation. To identify indexes of left ventricular function predictive of symptomatic and functional deterioration during the long-term course of asymptomatic patie...
