Resveratrol attenuated homocysteine-induced apoptosis of rat ventricular myocytes
Elevated homocysteine level in the plasma is a new independent important risk factor of ischemic heart diseases, stroke, dementia, Alzheimer's disease, renal failure, osteoporotic fracture, etc. In particular, increasing evidence has revealed a strong association of hyperhyomocystemia with cardiovascular diseases including heart failure, atrial fibrillation and venous thromboembolism, so that serum homocysteine level has been considered as a diagnostic marker of myocardial infraction and an important predictor of mortality for patients with coronary artery diseases (CAD) [1].

NT-proBNP in “low risk” patients with atrial fibrillation
Atrial fibrillation (AF) increases the risk of stroke and death and constitutes a significant societal health and economic problem [1,2]. Prediction of thromboembolic risk is most commonly made using a clinical score such as the CHADS2 or CHA2DS2–VASc [3]. N-terminal pro-B-type natriuretic peptide (NT-proBNP) is associated with mortality and cardiovascular events in patients with AF and has been shown to improve risk stratification beyond the CHA2DS2-VASc score [4]. However, the association between NT-proBNP levels and the CHA2DS2-VASc score as well as the prevalence of high NT-proBNP levels indicating high risk in othe...

Relationship between macular and retinal diseases with prevalent atrial fibrillation — An analysis of the Australian Heart Eye Study
Atrial fibrillation (AF) is the most frequent cardiac arrhythmia, which significantly and independently predicts morbidity and mortality. AF increases overall mortality risk by 40–90%, and may be associated with underlying cardiovascular disorders including stroke and heart failure [1]. Ocular diseases including diabetic retinopathy, age-related macular degeneration (AMD) and retinal vessel calibre changes are also significant predictors of cardiovascular disease and blood pressure [2]. However, their relationship with cardiac arrhythmias such as atrial fibrillation has been relatively unexplored.

Screening for atrial fibrillation in general practice: A national, cross-sectional study of an innovative technology
To test the use of three lead monitoring as a screening tool for atrial fibrillation (AF) in general practice. AF is responsible for up to a quarter of all strokes and is often asymptomatic until a stroke occurs.

Letter by Bassareo regarding the article of Larrson et al. “Incidence of atrial fibrillation in relation to birth weight and preterm birth”
we have read with great interest the commendable article by Larsson and Colleagues, who have demonstrated the association of low birth weight (in men) and high birth weight with an increased risk of the onset of atrial fibrillation. It implies an increased risk of developing an embolic stroke in these subjects as well [1].

Vitamin D deficiency and atrial fibrillation
Vitamin D deficiency has been linked with hypertension, coronary artery disease, and stroke, but there is no consensus regarding the possible association between vitamin D deficiency and atrial fibrillation (AF). Vitamin D negatively regulates the renin–angiotensin–aldosterone-system (RAAS), mediates calcium homeostasis, binds to vitamin D receptors on cardiac myocytes, and has antioxidant properties that may reduce levels of reactive oxygen species (ROS) in the atria, which contribute to inflammation and proarrhythmic substrate formation.

Primary prophylactic anticoagulation is mandatory if noncompaction is associated with atrial fibrillation or heart failure
Whether patients with left ventricular hypertrabeculation / noncompaction (LVHT) require primary prophylaxis with oral anticoagulation (OAC) to prevent stroke / embolism is unsolved [1]. However, if LVHT is associated with atrial fibrillation (AFIB) / atrial flutter (AFLU), or systolic dysfunction or both, OAC for primary prophylaxis of embolism is mandatory, as illustrated by the following case.

Female gender and atrial fibrillation: An association with worse prognosis and outcomes
Females with atrial fibrillation (AF) are at increased risk for ischemic stroke but have been under-represented in AF cohorts. Without anticoagulation, women are at higher risk than men for AF-related thromboembolic events (TE) but results are not consistent [1,2]. Interestingly, vascular complication rates after AF ablation had been recently shown to be also higher in females [3]. Female sex has been included in the CHA2DS2-VASc score for assessing thromboembolic risk, which doubles in women between the ages of 55 and 65, the menopausal period, when estradiol levels decrease by about 60% [4].

Hyperuricemia is independently associated with increased risk of atrial fibrillation: A meta-analysis of cohort studies
Atrial fibrillation (AF) is a common cardiovascular disease in the elderly and the most common cardiac arrhythmia [1]. AF increases risk of mortality morbidity, and is associated with risks of a series of subsequent diseases, such as cardiovascular disease, stroke, and impaired cognition [1–3]. A better understanding of AF risk factors is essential for the development of preventive strategies and treatment of AF. Though several studies were published to assess the association between hyperuricemia and AF risk, no consistent results were reported [4–10].

Association between Neutrophil to Lymphocyte Ratio and Atrial Fibrillation
Neutrophil to Lymphocyte Ratio(NLR) is a ratio of subtypes of leukocyte and has been attracting attention as a significant biomarker of systemic inflammation [1]. Inflammation has a significant role in atherosclerosis [2]. NLR has been shown to be related to adverse outcomes in patients with coronary heart disease (CHD) [3–9] and can independently predict mortality of CHD in an asymptomatic population [9]. Atrial fibrillation (AF) is one of the most common cardiac arrhythmias and increases the risk of stroke and death.

Psoriasis and risk of atrial fibrillation
Psoriasis is one of the most prevalent T-cell-mediated chronic inflammatory disorders affecting the skin, scalp, nails, and occasionally, joints. The prevalence of psoriasis in the general population ranged from 1% to 4% in population-based studies [1–3]. In recent years, several studies demonstrated that psoriasis is associated with an increased risk of cardiovascular (CV) diseases such as stroke, myocardial infarction (MI), peripheral vascular disease and CV death [4–11]. In a recently published review in the International Journal of Cardiology, Mosca et al.

Prothrombotic risk of vitamin K antagonists during the first days of treatment: One more reason to use new oral anticoagulants
In the controlled clinical trials ROCKET AF and ARISTOTLE, which included patients with nonvalvular atrial fibrillation (AF), introduction of warfarin was associated with an excess of ischemic strokes during the first 30days after randomization in vitamin K antagonist (VKA)-naive patients compared with warfarin-experienced patients (4.40/100 patient-years versus 2.86/100 patient-years in ROCKET AF and 5.41/100 patient-years versus 1.42/100 patient-years in ARISTOTLE) [1]. A similar observation was made in the RE-LY trial, in which the risk of ischemic stroke was 0.26% for warfarin versus 0.12% for dabigatran (odds ratio 2....

Meta-analysis of Risk of Stroke and Thrombo-Embolism with Rivaroxaban versus Vitamin K antagonists in ablation and cardioversion of atrial fibrillation
: Anticoagulation in cardioversion and ablation of atrial fibrillation is imperative for reducing thrombo-embolic events. Ample information is available about use of warfarin and vitamin K antagonists (VKA) but few trials examine safety and efficacy of rivaroxaban in these procedures. We aim to explore the hypothesis that rivaroxaban causes equal thrombo-embolic and bleeding events when used in atrial fibrillation patients undergoing ablation or cardioversion compared to VKA.
