BACKGROUND AND PURPOSE: The clinical benefit of endovascular stroke therapy has been demonstrated in several prospective randomized trials. However, in a relevant percentage of patients, mechanical thrombectomy bears the risk of causing new infarction in initially unaffected vascular territories through thrombus fragmentation and migration of clot debris. The goal of this study was to evaluate the use of the balloon guide catheter (BGC) to effectively achieve flow arrest and thrombus aspiration during the intervention to avoid distal embolization...

The epidemic of atrial fibrillation (AF) is increasingly recognised as a growing health problem worldwide. Although epidemiological studies on AF in the Asia-Pacific region are scarce, given the increasing age and size of populations in this region, the burden of AF is expected to be far greater than in North America and Europe. This is not only due to the growing, ageing population but also an increased incidence of risk factors for AF, such as hypertension, obesity, metabolic syndrome and diabetes, in the Asia-Pacific region...

Obesity and its associated metabolic dysregulation leading to metabolic syndrome is an epidemic that poses a significant public health problem. More than one-third of the world population is overweight or obese leading to enhanced risk of cardiovascular disease (CVD) incidence and mortality. Obesity predisposes to atrial fibrillation, ventricular, and supraventricular arrhythmias; conditions that are underlain by dysfunction in electrical activity of the heart. To date, current therapeutic options for cardiomyopathy of obesity are limited, suggesting that there is considerable room for development of therapeutic interventions with novel mechanisms of action that will help normalize rhythm in obese patients...

Atrial fibrillation (AF) is a common cardiac arrhythmia, and pathological burden can be influenced by environmental factors. The rural environment may influence the burden of AF, although no systematic review studies have been conducted to address this issue. We performed a systematic review of AF screening studies conducted in rural global populations to determine the burden, risk factors, and screening methods surrounding AF in these settings. Out of the 1792 articles gathered from a keyword search of medical databases and reference lists, 18 publications from 11 countries were included in our analysis...

Gout, the most prevalent inflammatory arthritis worldwide, is associated with cardiovascular and renal diseases, and is an independent predictor of premature death. The frequencies of obesity, chronic kidney disease (CKD), hypertension, type 2 diabetes, dyslipidaemias, cardiac diseases (including coronary heart disease, heart failure and atrial fibrillation), stroke and peripheral arterial disease have been repeatedly shown to be increased in gout. Therefore, the screening and care of these comorbidities as well as of cardiovascular risk factors are of outmost importance in patients with gout...

Atrial fibrillation (AF) and diabetes mellitus (DM) are common worldwide and their incidence is increasing, representing a significant public health and economic burden as well as an increase in individual increased morbidity and mortality risk profiles. Both conditions are closely related, as patients with DM are at increased risk of incident AF, and AF patients with DM are at higher risk of cardiovascular events compared to non-AF patients. Areas covered: This review article aims to provide an overview of the current evidence linking DM and AF, as well as the impact of obesity, weight loss and stroke on these coexisting conditions...

Atrial fibrillation (AF) is a common arrhythmia affecting a growing number of Canadians. Traditional risk factors, such as hypertension, diabetes, and valvular disease, are often present in older patients with AF. Modifiable risk factors should also be sought in patients presenting with new-onset AF. Obesity is a rapidly growing epidemic in Canada. Emerging evidence is linking obesity and the often coexistent obstructive sleep apnea with an increased incidence of AF. Alcohol intake can also predispose to the development of AF...

In recent years, the anatomic and functional contiguity of epicardial adipose tissue (EAT) to myocardium and coronary arteries has gained increasing interest for its potential pathogenetic role in obesity-related cardiac diseases. Besides its known and attributed biochemical cardioprotective properties, it is becoming evident that, in metabolic disease states, EAT-secreted bioactive molecules may play an important role in the pathogenesis of coronary artery disease and cardiac arrhythmias. EAT-derived inflammatory cytokines and reactive oxidative species may, indeed, play a part in the development of a local proatherogenic milieu by paracrine and vasocrine mechanisms of interaction...

Atrial fibrillation (AF) is a leading cause of cardiovascular morbidity and mortality worldwide. Management of AF is a complex process involving: 1) the prevention of thromboembolic complications with anticoagulation; 2) rhythm control; and 3) the detection and treatment of underlying heart disease. However, cardiometabolic risk factors, such as obesity, hypertension, diabetes mellitus, and obstructive sleep apnoea, have been proposed as contributors to the expanding epidemic of atrial fibrillation (AF). Thus, a fourth pillar of AF care would include aggressive targeting of interdependent, modifiable cardiovascular risk factors as part of an integrated care model...

OBJECTIVES: Detection of atrial fibrillation (AF) in post-cryptogenic stroke (CS) or transient ischemic attack (TIA) patients carries important therapeutic implications. METHODS: To risk stratify CS/TIA patients for later development of AF, we conducted a retrospective cohort study using data from 1995 to 2015 in the Stanford Translational Research Integrated Database Environment (STRIDE). RESULTS: Of the 9,589 adult patients (age ≥40 years) with CS/TIA included, 482 (5%) patients developed AF post CS/TIA...

BACKGROUND: Early life risk factors are associated with cardiometabolic disease, but have not been fully studied in atrial fibrillation (AF). There are discordant results from existing studies of birth weight and AF, and the impact of maternal body size, gestational age, placental size, and birth length is unknown. METHODS AND RESULTS: The Helsinki Birth Cohort Study includes 13 345 people born as singletons in Helsinki in the years 1934-1944. Follow-up was through national registries, and ended on December 31, 2013, with 907 incident cases...

Tall stature or obesity has been associated with higher risk of atrial fibrillation (AF), but reported effects of aerobic fitness have been conflicting. A national cohort study was conducted to examine interactions between height or weight and aerobic fitness among 1,547,478 Swedish military conscripts during 1969-1997 (97-98% of all 18-year-old males) in relation to AF identified from nationwide inpatient and outpatient diagnoses through 2012 (maximum age 62). Increased height, weight, or aerobic fitness (but not muscular strength) at age 18 was associated with higher AF risk in adulthood...

The prevalence of atrial fibrillation (AF) is constantly rising. Different studies have underlined the correlation between AF and modifiable risk factors such as obesity, obstructive sleep apnea, hypertension and sedentary lifestyle. Treatment of these comorbidities could significantly reduce the AF burden and the recurrence rate after cardioversion or ablation. These data should therefore lead to a paradigm shift in the management of AF. A strategy limited to catheter ablation or to the prescription of an antiarrhythmic drug is not sufficient...

Cardiac obesity makes an important contribution to the pathogenesis of cardiovascular disease. One of the important pathways of this contribution is the inflammatory process that takes place in the adipose tissue. In this review, we consider the role of the cardiovascular system-associated fat in atherosclerotic cardiovascular pathology and a non-atherosclerotic cause of coronary artery disease, such as atrial fibrillation. Cardiovascular system-associated fat not only serves as the energy store, but also releases adipokines that control local and systemic metabolism, heart/vascular function and vessel tone, and a number of vasodilating and anti-inflammatory substances...

Obstructive sleep apnoea (OSA) is very common in patients with Type 2 diabetes (T2D), which is not surprising considering that obesity is a common risk factor for both conditions. In general population studies, OSA has been shown to be associated with several comorbidities including increased risk of road traffic accidents, T2D, hypertension and lack of nocturnal dipping of blood pressure, hyperlipidaemia, increased inflammation, increased risk of cardiovascular disease and mortality, increased risk of atrial fibrillation, worse quality of life, and erectile dysfunction...

Type 2 diabetes mellitus (T2DM) and obesity are important contributors to nonischemic heart failure (HF) and atrial fibrillation. There is a 2- to 5-fold increase in HF associated with T2DM, and there is a 5% in HF risk in men and 7% increment in women for every unit increment in body mass index, after adjustment for traditional cardiovascular risk factors. Likewise, the risk of atrial fibrillation increases by about 6% per unit increase in body mass index. Metabolic cardiomyopathy leads to a number of changes in cardiac structure and function that can be recognized by imaging in the asymptomatic phase, and these parameters can be used for monitoring the progression of disease or the response to therapy...

BACKGROUND: Heart failure (HF) readmission rates have become an increasingly important quality metric since the advent of the Hospital Readmissions Reduction Program. Despite many well-intentioned efforts to reduce readmissions, clinicians continue to struggle with the problem of high HF readmission rates. HYPOTHESIS: HF patients with obstructive sleep apnea (OSA) will have higher burden of rehospitalization and mortality than HF patients without OSA. METHODS: Our study included 344 patient encounters (among 271 unique patients) with a diagnosis of HF from September 2014 through September 2015...

Increased body mass index (BMI) and obesity are associated with greater risk of atrial fibrillation (AF). However, whether this correlation is independent and gender specific remains unclear. The objective of this study was to characterize the relation between BMI, left atrial (LA) size, and presence of AF and determine whether this association is gender specific. We prospectively studied 499 patients who underwent a transthoracic echocardiogram at an academic tertiary care medical center. Clinical and echocardiographic data were obtained...
