Arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) is an inherited heart muscle disease associated with increased risks of sudden death, particularly in young, otherwise healthy, patients. The pathologic features are progressive myocardial atrophy and fibrofatty replacement. Plakophilin-2 (PKP2) is reported as the most common ARVD/C-causing(More)
OBJECTIVE To explore the prevalence of depression and (or) anxiety disorders among cardiovascular outpatients of tertiary general hospitals of five Chinese cities. METHODS A hospital-based cross-sectional survey was conducted in the cardiovascular out-patient departments of 14 tertiary general hospitals in five Chinese cities. The patients aged 18 years(More)
Autophagy is promoted as a response to such environmental stress conditions as ATP depletion and excessive accumulation of reactive oxygen species (ROS). Multiple signalling pathways, including AMP-activated protein kinase (AMPK), are indicated to promote autophagy in ischaemic/hypoxic (I/R) heart. However, it's far more to clarify the orchestrated(More)
OBJECTIVE To determine whether the extent of prolongation of the transisthmus interval after ablation predicts complete bidirectional block. METHODS Since 1996 to 2002, 30 consecutive patients underwent ablation procedures for isthmus-dependent atrial flutter. There were 23 males and 7 females [mean age (47.85 +/- 9.35) years]. With the use of(More)
OBJECTIVE The purpose of this study was to screen genetic variations in plakophilin-2 (PKP2) gene in patients with arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) and investigate the differences in clinical features between mutation and no-mutation groups. METHODS Thirty unrelated Chinese patients clinically diagnosed with ARVC/D and 50(More)
OBJECTIVE To study various types of supraventricular arrhythmias in patients with Brugada Syndrome. METHODS Forty six patients with ECG of spontaneous type Brugada and with ventricular and/or supraventricular tachyarrhythmia, without structural heart diseases which were excluded by echocardiography, underwent 24 h-Holter recording, electrophysiological(More)
BACKGROUND Whether diabetes mellitus (DM) is a predictor of long-term adverse clinical outcomes after repeat drug eluting stent (DES) implantation for DES in-stent restenosis (ISR) remains controversial. We sought to evaluate the effect of DM on the long-term clinical outcomes in patients undergoing repeat DES implantation for DES-ISR lesions. METHODS In(More)
In the present work, Monte Carlo simulations were employed to study the characteristics of the dose distribution of high energy electron beam in the presence of uniform transverse magnetic field. The simulations carried out the transport processes of the 30 MeV electron beam in the homogeneous water phantom with different magnetic field. It was found that(More)
BACKGROUND Ouabain and digoxin are important cardiac glycoside and related to many cardiovascular diseases. The purpose of this study was to investigate the changes of sodium pump α-subunit expression in rats and compare the effects of ouabain (OUA) and digoxin (DIG) on the development of hypertension. METHODS In situ hybridization was performed. Specific(More)
AIMS To observe the influence of the peroxisome proliferator-activator receptor-G (PPAR-G) gene and cytochrome P4501A1 (CYP1A1) single-nucleotide polymorphisms (SNPs), and interactions among several SNPs on coronary artery disease (CAD) risk. METHODS A total of 1106 participants (including 583 males and 523 females) including 550 CAD patients and 556(More)
