NPPB and atrial fibrillation: This study found a correlation between supraventricular arrhythmias and plasma biomarkers levels, and that the combination of NT-pro-BNP and frequent SVEs was more common among subjects with elevated CHARGE-score, which supports the idea that atrial myopathy is caused by established AF risk factors, and that intervention against modifiable risk factors may slow the progression from atrial myopathy to AF.
