OBJECTIVE To define the relationship between changes in insulin sensitivity and attenuation of hypertension. METHODS We investigated whether troglitazone (CS-045, an insulin sensitizer) has an antihypertensive effect in fructose (FRU)-fed Wistar rats with insulin resistance and simultaneously compared its hypotensive efficacy with those of alacepril (ALA,(More)
To determine whether hypoglycemic agents such as sulfonylureas, biguanides and the newly developed insulin sensitizers such as troglitazone, have hypotensive effects in an animal model of non-insulin-dependent diabetes mellitus associated with insulin resistance, male Otsuka Long Evans Tokushima Fatty (OLETF) rats aged 12 weeks were administered following(More)
BACKGROUND Recent studies demonstrated that oral anticoagulants (OACs) should be considered for patients with atrial fibrillation and 1 risk factor in addition to sex. Because age is an important determinant of ischemic stroke, the strategy for stroke prevention may be different for these patients in different age strata. The aim of this study was to(More)
We have previously demonstrated that captopril ameliorates glucose intolerance by partially preventing the reduction in postprandial skeletal muscle blood flow. The present study was designed to clarify the mechanism by which ACE inhibitors affect glucose metabolism in fructose (FRU)-fed Wistar rats with hypertension, glucose intolerance and(More)
BACKGROUND Frequent ventricular premature complexes (VPCs) can lead to the development of dilated cardiomyopathy and sudden cardiac death. Renal artery sympathetic denervation (RDN) may protect the heart from remodeling. This study aimed to investigate the effect of frequent VPCs on structural and electrical properties and whether RDN can protect the heart(More)
Colchicine is a microtubule disruptor that reduces the occurrence of atrial fibrillation (AF) after an operation or ablation. However, knowledge of the effects of colchicine on atrial myocytes is limited. The aim of this study was to determine if colchicine can regulate calcium (Ca(2+) ) homeostasis and attenuate the electrical effects of the extracellular(More)
BACKGROUND Botulinum toxin (BTX), temporarily suppressing cholinergic transmission (<3 weeks), has been reported to suppress atrial fibrillation (AF) for ≥1 year. We aimed to investigate the mechanism underlying long-term suppression of AF caused by injecting BTX into major atrial ganglionated plexi (GPs). METHODS AND RESULTS Bilateral thoracotomies in(More)
BACKGROUND Chronic kidney disease (CKD) increases the occurrence of atrial fibrillation and pulmonary vein (PV) arrhythmogenesis. Calcium dysregulation and reactive oxygen species (ROS) enhance PV arrhythmogenic activity. The purposes of this study were to investigate whether CKD modulates PV electrical activity through dysregulation of calcium homeostasis(More)
