Chromosome 4q25 variants and atrial fibrillation recurrence after catheter ablation.

OBJECTIVES This study tested the hypothesis that chromosome 4q25 single-nucleotide polymorphisms (SNPs) associate with atrial fibrillation (AF) recurrence after catheter ablation. BACKGROUND Recent genome-wide association studies identified 2 SNPs on chromosome 4q25 associated with AF. Although the mechanisms underlying this increased risk are unknown… CONTINUE READING
