Abstract

Atrial fibrillation (AF) is closely associated with metabolic syndrome, and the receptor for advanced glycation end products (RAGE) pathway is involved in insulin resistance and cardiac remodelling. We hypothesized that plasma level of soluble RAGE (sRAGE) would predict clinical outcome after radiofrequency catheter ablation for AF. We measured pre-procedural plasma level of sRAGE in 496 patients who underwent AF ablation (142 patients with diabetes, 354 patients without diabetes selected by matching them with diabetic patients according to age, sex, and AF type). (i) Plasma level of sRAGE was significantly higher in diabetic patients than in non-diabetics (580.0 ± 576.4 vs. 435.8 ± 280.7 pg/mL, P = 0.005), but there was no difference in sRAGE levels between patients with clinical recurrence of AF and those without. (ii) During 24.5 ± 18.0 months of follow-up, the recurrence of AF was significantly lower in the diabetic patient group with high sRAGE (≥418 pg/mL based on the median value) than the diabetic patient group with low sRAGE (log-rank P = 0.045). This was especially pronounced in patients with paroxysmal AF and diabetes (log-rank P = 0.016), but no association was found in non-diabetics. (iii) In multivariate Cox regre...Continue Reading

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Cardiac Remodeling

Cardiac remodeling in response to a myocardial infarction is characterized by progressive ventricular dilatation, cardiac hypertrophy, fibrosis, and deterioration of cardiac performance. Discover the latest research on Cardiac Remodeling here.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
