Metabolic syndrome associates with left atrial dysfunction

Obesity and metabolic syndrome (MetS) are risk factors of atrial fibrillation (AF), but limited data exist on their effect on left atrial (LA) function. The aim of the study was to evaluate the effects of cardiac, hepatic and intra-abdominal ectopic fat depots and cardiometabolic risk factors on LA function in non-diabetic male subjects.

Abstract Atrial fibrillation (AF) is the most common arrhythmia encountered in clinical practice with implications on long-term outcomes. Metabolic disorders including diabetes mellitus and obesity are independent predictors of atrial fibrillation and present therapeutic targets to reduce both the incidence and duration burden of atrial fibrillation. The presence of pericardial fat in direct contact with cardiac structures, as well the subsequent release of proinflammatory cytokines, may play an important role in this connection. Atrial fibrillation is an independent predictor of cognitive impairment and dementia....

Abstract Introduction: Metabolic syndrome (MetS) is defined as an association between diabetes, hypertension, obesity and dyslipidemia and an increased risk of cardiovascular disease. Mitral annular calcification (MAC) is associated with several cardiovascular disorders, including coronary artery disease, atrial fibrillation (AF), heart failure, ischemic stroke and increased mortality. The CHA2DS2-VASc score is used to estimate thromboembolic risk in AF. However, the association among MAC, MetS and thromboembolic risk is unknown and was evaluated in the current study. Methods: The study group consisted of 94 patients with ...

Conclusion: These findings limit the possible roles of gene transcriptional changes in previously reported age-dependent pro-arrhythmic electrophysiologial changes observed in Pgc-1β-/- atria to an altered Ca2+-ATPase (Atp2a2) expression. This directly parallels previously reported arrhythmic mechanism associated with p21-activated kinase type 1 deficiency. This could add to contributions from the direct physiological outcomes of mitochondrial dysfunction, whether through reactive oxygen species (ROS) production or altered Ca2+ homeostasis. Introduction Atrial arrhythmias constitute a major public health probl...

In this study we aimed to investigate the EFT in patients with MAC.Methods: The study group consisted of 78 patients with MAC. An age, gender and body mass index matched control group consisted of 47 subjects who admitted to echocardiography laboratory due to suspicion of organic heart disease and eventually found to be free of MAC. We measured EFT in patients with MAC and control subjects.Results: EFT was significantly higher in patients with MAC than in control subjects (5.7 ±0.9 vs. 4.4±0.6 mm respectively; P

Conclusions: Our study shows that a higher burden of liver steatosis seems to be associated with less severe stroke and better functional outcome after ischemic stroke or TIA. Introduction Non-alcoholic fatty liver disease (NAFLD) is a spectrum of diseases from simple steatosis to steatohepatitis with varying degree of fibrosis, and liver cirrhosis (1, 2). NAFLD is becoming the most common chronic liver disease worldwide including Korea, affecting approximately 25% of the general population (3, 4). NAFLD is closely associated with obesity, insulin resistance, and type 2 diabetes mellitus, and is even recognized as ...

Abstract Type 2 diabetes mellitus (T2DM) substantially increases the risk of cardiovascular events, including heart failure (HF), due to complications such as hypertension, obesity and dyslipidemia based on metabolic syndrome, which plays the central pathological role in HF. A reason is that T2DM causes left ventricular (LV) diastolic dysfunction beginning in the early phase of the disease, which in turn increases the risk of development of HF independently of the control of blood glucose levels, blood pressure or the presence of coronary artery diseases. Intracellular metabolic disorders and increased oxidative s...

ConclusionsMetS associates with subclinical LA dysfunction. Multiple components of MetS are related to LA dysfunction, notably visceral obesity and insulin resistance. Further studies are needed to elucidate the role of mechanical atrial remodeling in the development of AF.

Abstract BACKGROUND: Although the prevalence of both atrial fibrillation (AF) and metabolic syndrome (MetS) has been increasing in East Asia, the association between them is uncertain.Methods and Results:A total of 24,741 middle-aged Korean men without baseline AF were enrolled in a health screening program from January 2003 to December 2008. Among them, 21,981 subjects were evaluated to determine the risk of AF based on baseline MetS status through December 2016. At every visit, the subjects were evaluated for AF using ECG. MetS was defined using the criteria of the International Diabetes Federation and was p...

Cardiovascular outcome in type 2 diabetes and atrial fibrillation. Herz. 2018 May 02;: Authors: Costard-Jäckle A, Tschöpe D, Meinertz T Abstract Diabetes is an independent risk factor for atrial fibrillation (AF). Frequently, it is part of the metabolic syndrome cluster, which includes obesity and hypertension that are independently associated with AF. The risk appears to be higher with longer duration of diabetes and inadequate glycemic control. Patients with diabetes and AF have a substantially increased risk of death and serious cardiovascular complications compared with those in...

Conclusion In summary, although it is not possible to exclude confounding factors, the timing and dose-dependent effect of aripiprazole administration in our patient suggests an association between an initial intramuscular injection of long-acting aripiprazole and new onset of AF. This observation calls for clinical vigilance, not only in patients with additional risk factors for stroke but also in younger patients who might have predisposing factors for arrhythmias.
