Background: Although magnesium deficiency induces left ventricular dysfunction, it is not known whether both systolic and diastolic functions are altered to the same extent. In this study, we investigated the effects of theophylline on left ventricular function in rats fed a normal diet or a magnesium-deficient diet for 1 month, and determined whether K201, a multi-channel blocker, modulated the effects of theophylline. Methods: Theophylline was infused at 5 mg/kg/min for 15 min in 6 control rats and 6 magnesium-deficient rats, and hemodynamic measurements were performed...

Background: Hypoxia/reoxygenation (H/R) in human umbilical vein endothelial cells (HUVECs) induces oxidative stress and eventually leads to vascular injury. Objective: The aim of this study was to examine the effect of melatonin on HUVECs injured by H/R and explore the underlying mechanisms. Materials and Methods: A model of HUVECs under hypoxia/reoxygenation was established. Cell migration and adhesive ability was measured by wound healing and adhesion assays...

Background: Type D, otherwise known as distressed personality type, has been associated with an increased risk of cardiovascular morbidity and mortality. Blood pressure reactivity and recovery to stress could be a possible underlying pathway linking type D personality and cardiovascular events. Methods: A total of 41 patients with hypertension were recruited from a regional hospital in southern Taiwan. Demographic and clinical characteristics were obtained from all participants...

Background: Periodic electrocardiography (ECG) at every clinical visit is generally performed for heart rhythm surveillance, and 24-h Holter ECG is usually used as the gold standard. We aimed to investigate the electrocardiographic features of persistent atrial fibrillation (AF) accompanied with second-degree atrioventricular block (AVB). Methods: From October 2012 to November 2015, 204 patients with an RR interval > 2.0 s before radiofrequency ablation were included...

Background: Atherosclerosis (AS) is defined as chronic inflammation of the vessel wall. The major objective of the this study was to explore the mechanism of Treg/Th17 imbalance and the role of high mobility group box-1 protein (HMGB1) on the balance in AS. Methods: We detected the apoptotic ratios of Treg and Th17 cells in peripheral blood mononuclear cells (PBMCs) from subjects with AS and normal coronary arteries (NCA) by flow cytometry. The effects of recombinant HMGB1 (rHMGB1) on the proportion, apoptosis and differentiation of Treg and Th17 cells were analyzed using flow cytometry, qRT-PCR and ELISA...

Background: Many techniques, methods and closure devices have been developed in order to reduce vascular complications that occur after coronary and peripheral interventions. The aim of the present study was to identify which method i.e. ultrasound (US) guidance or traditional access technique, is better for common femoral artery cannulation. Methods: The study included 939 patients, who were assigned to either the US-guided cannulation group (n = 449) or manual technique group (n = 490)...

Objective: Nesfatin-1 is a novel anorectic neuropeptide with potent metabolic regulatory effects. It regulates blood pressure, heart rate, cardiomyocyte metabolism and permeability. SYNTAX score, which is an angiographic scoring system, defines the grade and complexity of coronary artery disease (CAD). We aimed to evaluate the relationship between nesfatin-1 level and severity of CAD according to the SYNTAX score in patients with non-ST segment elevation myocardial infarction (NSTEMI)...

Background: Sphingosine 1 phosphate, an active sphingolipid metabolite, functions in both healthy and diseased cardiovascular systems. It has been reported to play a role in angiogenesis and arteriogenesis in various tissues, which are the proposed mechanisms for the development of coronary collateral circulation. To the best of our knowledge, no data exist regarding serum sphingosine 1 phosphate levels and the presence of coronary collateral circulation in the literature. Thus this study aimed to investigate serum sphingosine 1 phosphate levels in patients with and without coronary collateral circulation...

Intensive lipid lowering therapy is important in patients with acute coronary syndrome (ACS) and stable coronary artery disease (CAD). The 2017 Taiwan Lipid Guidelines for High Risk Patients was recently published. The guideline suggests that low-density lipoprotein cholesterol (LDL-C) should be the primary target, and that the treatment goal of LDL-C is < 70 mg/dL for patients with ACS or stable CAD. A lower target of < 55 mg/dL is appropriate for patients with ACS and diabetes mellitus. Non-high-density lipoprotein cholesterol (non-HDL-C) < 100 mg/dL can be considered as the secondary target after achieving the LDL-C goal for patients with a triglyceride level > 200 mg/dL...

Background: Atrial fibrillation (AF) presents a potential challenge when performing coronary computed tomography angiography (CTA). To date, there is no ideal protocol for CTA in patients with AF. We sought to design a protocol for single-heartbeat coronary CTA in patients with AF. Methods: We enrolled 32 patients with AF and a very low probability of coronary artery disease who were referred for CTA to assess pulmonary vein anatomy for catheter ablation. A 256-slice scanner was used...

Background: Ischemia of the atria and conductive system of the heart results in greater atrial electrophysiological changes and propensity for atrial fibrillation. P wave duration and dispersion have been proposed to be useful for the prediction of paroxysmal atrial fibrillation (PAF). This study aimed to investigate the effect of coronary artery dominance on P wave duration and dispersion. Methods: The study population included 194 patients with left dominant circulation (LDC) and 200 age- and gender-matched controls with right dominant circulation (RDC) and without coronary artery disease based on invasive coronary angiography findings...

Background: Atrioventricular nodal reentrant tachycardia (AVNRT) is one of the most common supraventricular tachycardia substrates. The aim of this study was to demonstrate the excellent outcomes of cryoablation without fluoroscopy in pediatric patients with AVNRT. Methods: From September 2015 to October 2016, a transcatheter cryoablation procedure was performed in 109 patients using the EnSite® system. After electrophysiologic studies, a cryoablation catheter was advanced for the purpose of ablation of the slow pathway...

Background: Neurological complications are an important concern in the repair of type A aortic dissection. Supra-aortic involvement is considered to be an important risk factor for neurological injuries. However, the optimal brain protection strategy still remains controversial. The aim of the present study was to assess the efficacy and short-term results of retrograde cerebral protection techniques in the treatment of acute type A aortic dissection. Methods: Between 2005 and 2013, 185 patients who underwent repair of acute type A aortic dissection were enrolled in this study, all of whom received retrograde cerebral perfusion...

Background: Although left ventricular systolic dysfunction (LVSD) is a major cause of morbidity in human immunodeficiency virus (HIV)-infected patients, there is limited data on cardiac functions of these patients. Compared to the conventional echocardiography, the global longitudinal strain (GLS) can detect subclinical myocardial dysfunction at an earlier stage. Objectives: In our study, we aimed to evaluate left ventricular systolic functions using the GLS in HIV-infected patients and to investigate the effect of cluster of differentiation 4 T-cell values on LVSD...
