Catheter ablation of AF is now a mainstream procedure. Continuing technical advances are needed to achieve better results with more uniformity and reduced procedure times.

An elevated triglyceride (TG)/high-density lipoprotein (HDL) ratio has been described as a predictor of insulin resistance and cardiovascular events. We evaluated whether a TG/HDL ratio > or = 3.5 was associated with the burden of coronary artery disease (CAD) on cardiac catheterization. A retrospective chart review of 156 consecutive adults presenting to the Montefiore Medical Center Emergency Department with symptoms of unstable angina and no known history of CAD who underwent cardiac catheterization as part of their index hospitalization was performed. TG and HDL data were available in 100 patients within 6 months prior to admission and no more than 24 hours after presentation. A priori, a burden of CAD score was developed. On multivariate analysis, a TG/HDL ratio > or = 3.5 was associated with the burden of CAD (odds ratio, 2.87; 95% confidence interval, 1.03-7.96; p = 0.04). Further study is warranted.
