Congenital long- or short-QT syndrome may lead to life-threatening ventricular tachycardia and sudden cardiac death. Apart from the rare disease-causing mutations, common genetic variants in CAPON, a neuronal nitric oxide synthase (NOS1) regulator, have recently been associated with QT interval variations in a human whole-genome association study. CAPON had(More)
Reactive oxygen species are important mediators exerting toxic effects on various organs during ischemia-reperfusion (IR) injury. We hypothesized that adipose-derived mesenchymal stem cells (ADMSCs) protect the kidney against oxidative stress and inflammatory stimuli in rat during renal IR injury. Adult male Sprague-Dawley (SD) rats (n = 24) were equally(More)
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 focal AT arising from different parts of the SVC, the AT occurred spontaneously, rather than being induced by electrical stimulation. The cycle length of the tachycardia was highly(More)
BACKGROUND To investigate the age-dependent impact of the superfast door-to-balloon (D2B) times of ≤60min as recommended by the new ESC Guideline for patients with ST elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI) on mid-term survival rates based on a single center registry dataset. PATIENTS AND(More)
This study presents a novel wireless, ambulatory, real-time, and autoalarm intelligent telecardiology system to improve healthcare for cardiovascular disease, which is one of the most prevalent and costly health problems in the world. This system consists of a lightweight and power-saving wireless ECG device equipped with a built-in automatic warning expert(More)
OBJECTIVES The aim of this study was to characterize the relationship between impaired sympathetic innervation and arrhythmia with noninvasive biologic imaging in an animal model of post-infarct ventricular tachycardia (VT). BACKGROUND Innervation might be abnormal in the normally perfused borderzone of myocardial infarction, contributing to myocardial(More)
Platelet activation and its interaction with leukocytes play an important role in atherothrombosis. Cardiovascular diseases resulted from atherothrombosis remain the major causes of death worldwide. Gallic acid, a major constituent of red wine and tea, has been believed to have properties of cardiovascular protection, which is likely to be related to its(More)
OBJECTIVES Chronic inflammatory disease may trigger vascular atherosclerosis. This study aimed to determine whether chronic osteomyelitis (COM) is linked to an increased risk of coronary heart disease (CHD). METHODS A national insurance claim dataset of more than 23 million enrolees was used to identify 15 054 patients with newly diagnosed COM and 60 216(More)
This case-control study was carried out to investigate the possible relationship between the gene frequencies of HLA-DRB1, -DQA1 and -DQB1 alleles/haplotypes and rheumatic heart disease (RHD) among the Chinese population in Taiwan. A group of 115 patients with RHD documented by echocardiography, and a group of 115 normal controls were studied. The HLA-DRB1,(More)
Despite great advances in therapy over the past decades, ischemic heart disease (IHD) remains the leading cause of death worldwide because the decrease in mortality after acute myocardial infarction (AMI) leads to a longer life span in patients with chronic postinfarct heart failure (HF). There are no existing medical treatments that can cure chronic HF and(More)
